10x Atmega664 in PDIP
10x Atmega8535 in PDIP
5x ATxmega32A4U in TQFP
5x ATxmega256A3 in TQFP

Im addicted; I have way to many AVRs. I have one atmega32 on my breadboard right now and its been there for months. I have something around 60 AVRs; and ~58 of them never been touched. (Now ~75 with these).

and whats really lame is I did a side by side comparison of a few of my atmegas today and noticed they are all the same really, besides maybe one or two peripherals difference.. basicly if you have one mega you have them all!!!1

Also, not shown but my samples from microchop arrived:

3x PIC24F somthing (A pic i can program with the bus pirate pic programmer finally test that)
3x MCP2200 (UART <-> USB)
3x MCP4801 (DAC)
3x RE46C140E16F (a gas detection IC)
3x MCP4662 (Digital POT)
3x MCP23017 (IO Ex pander, excited about this)

I just got this bad boy from some hongkong ebay seller. It's a 100mW 433Mhz Transceiver based on the CC1101. Exactly the same radio module that is inside the CC430 in my ez430-Chronos watch. My hope is to interface this with TI's wireless stack and create a central node which will sync my Chronos watch automatically.

@BrentBXR
this is a lot of atmega  ;o) you should build a super computer with all of them ;-)
i also got few sample from microchip,  those i2c io ports are cool i will use one soon in a little prototype :-)

@Greeeg
i wish you fun with you  ez430-Chronos watch, i wish you will document your project, that watch seems to be really fun and i might get one too  :-)

I just bought this (well about month ago, but it is waiting to be hacked).

(http://http://online.twincar.sk/~robot/foto/vf/IMG_20111216_191446-r.jpg)

RF tube amp, 0-600mhz (most HAM bands), power estimated to ~250W CW, ~400W PEP. Contains 2x 4cx250 tubes. Probably from MIG-xx airplane.

@Greeeg: I bought RFBee from seeed for the same purpose, my chronos is 868mhz.

I bought this a couple days ago (has not yet arrived)

[attachment=0]

now I messed up because the price was so nice (at first) I bid and relised they made up for it with shipping! Doh the classic ebay mess-up... Oh well still a decent price... but I messed up worse in the fact that this is a 220v not 110v...

So now i need to 1) buy a converter or 2) make a project out of it and convert it.

Post by: arhi on January 19, 2012, 01:33:12 pm
most of them have transformer with both 230 and 110 input so it might be easy fix

I just bought a Rigol DS1052E oscilloscope and got it yesterday.

Been having fun playing with it, it looks great.
However before I got it, I had lots of ideas for projects which I never did because I kept thinking "I could do this if only I had a 'scope". But now I have one I can't remember any of those ideas :P

So many cool parts! I just got more STN1110 and a bunch of parts for my open source OBD-II bluetooth adaptor. It takes care of all the physical layer stuff so you don't have to.

2 strings of these, I have "mostly" got them talking to my Ardu and by talking I mean I can make them go mental. Some more work on the protocol as they don't conform to the standard chips from the Adafruit/FastSPI libraries.

Such is life, this is all part of the fun though, isn't it?

Just got done with my BusPirate Free PCB Build today. Haven't had a chance to test it or anything like that (honestly don't even have an arduino yet LOL). I'm actually pretty proud as it was my first SMD soldering attempt and I think I did everything right. I'm not as sure on capacitors/diodes and their placement direction.

I got this in the mail today:
A FPGA dev board with 32MB SDRAM, 8MB flash and 0.5MB SRAM.
It got a EP2C8 FPGA, fun fun :D
It came with the adapter (next time, email ebay guy that you live in the Netherlands, else you get an unusable adapter) and LCD
Tweezers so happen to arrive at the same day.
Ow, right, if you order a USBBlaster FPGA programmer from seller A and a dev board from seller B you WILL get the dev board first and WILL be waiting impatiently for the programmer :(

An HP 1650A 80 port LOGIC ANALYZER W LEADS & SOFTWARE. In near mint condition!
and an HP Hewlett Packard 54502A dual channel Digitizing Oscilloscope 400MHz. Also in perfect condition. Paid less than $300 for both (including shipping.)
well spent time on the Ebays.

I just came from HAM swap meet. For 200czk (10 usd) I got this:

(http://http://online.twincar.sk/~robot/foto/digi/small/IMGP0351.JPG)

It's some kind of counter/stopwatch - not sure. But there are 8 nixie tubes, with working powersupply. This is old-school technology, containing piles of 74xx ICs (which draw 25-50mA each!). One board is missing. But the box is nice, for some other project.

2 Nokia 5110 LCDs with boards, 3 Nokia 3210 LCDs, and another 5 Nokia 3210 full phones, not working, (but LCDS should be intact)
The best part was the price, $10, that's 10 LCD's for $10 :D I like using 3210 and 5110 better then 3310s because the lcds for 3210 and 5110 come with metal cases around them making it easier to connect them to the board.

I've been buying a ton of odds and ends from ebay. This is:
200 SOT-223 3.3volt VREG
400 male to male breadboard wires (super poor quality, but get the job done)
200 12MHz crystals
100 2 terminal screw blocks (always too expensive at mouser, these were only $3 shipped)
10 2x5P sockets. These are so hard to get the right one, cheap, from mouser that we only use pin header in prototypes. Now we can use sockets too.

Still to come: a box of rotary encoders and knobs.

I ordered 5 different items from Amazon.co.uk, total 6 items, so two pieces of one item.

Now I got delivery information. I will get 3 Parcels from Royal Mail, and one from DHL. I'm wondering how my sub-£30 order gets this kind of delivery :D At least I'm having fun time to fetch packets from post office and opening them... LOL I must say.

Edit: More on topic: I bought used Buffalo Linkstation (Linux NAS box) without HDDs for 6€. I'll be hacking the box to turn it to NAS/irssi/http?/etc-box :)

That post on DP is exactly what got me interested, but I wanted more specific information. :P

I would just link to the thread but I realized that the pictures make the thread HUGE and load slowly even on my 1.5 MB/s connection, so I will just put the quote here. It is directly from digikey.

Quote
Digi-Key does accept personal checks from customers within the U.S. There are two ways you could pay using a personal check. First, you could do what we call a pre-paid order, where you would send us a list of your parts. (either mail or you could enter the items on the website and then under billing select contact me, and then in order notes reference that you will be sending in a check.) Once we receive the copy of your parts we would let you know the total and once we receive your check in the mail we would then process the order and ship. No stock is reserved until we receive the payment. Digi-Key would pay for shipping which is usually shipped UPS Ground. Once the order clears the shipping department if you provide an email address you would receive an automatic email confirmation stating the order is being shipped. Second option would be to place an order via phone, fax, email, or on the website and select to pay via COD. With this you would pay the UPS or USPS carrier when they deliver your package. You would be responsible for shipping charges and I believe there would be a COD charge as well. If you use a personal check for that we would just need the bank information from your check. (Bank name and location, check #, routing #, and account #...ect)

Anyways; Today some more ebay stuff arrived:

A dry soldering sponge (I dont like it as much as just a wet cloth (not wet sponge but wet cloth wroks best for me)
I re-upped my supply of male and female headers (including straight and 90)
I re-upped SMD to DIP breakout boards
I re-upped on Kester 951 bottles x3 (alot) but i think its just iso alochole i dont think its flux, i was ripped of
I got some new AMTECH NC-559-ASM no-clean syringe flux, this stuff works GREAT my new fav for PCB, non-pcb i use AMTECH 223
Some assortment of wire
some assortment of heat shrink
and other odds and ends; including 50 Pcs of assorted clear LEDs (needed a re-up, i love ebay)

To lazy to take pics... My ATTEN hot air rework station arrived a few days ago; still have not used it

i bought this dcdc converter (Sparkfun) for a project who has been put on a shelve .:-(

so now i might going to used it for building me a poor man power supply :o)
i already have a hacked pc PSU but i need something adjustable...
fast try it is good for 2 -3A like that, (6A wih cooling) 
so i will have to find a way to put heatsink on it ...

2 minors implementations problems

-the resistor trim vs output voltage isn't a nice linear one... 
so i will have to find a way to have a nice coarse and fine adjustment

-the complete range [0.59, 5.5]volts output cannot be done with a single 12volt or 5volt input
so at some point i will have to change between input source

maybe a small pic with a latch-able relay and a digital pot will solve both problems
anyone have done this with this guy ?

i might also completely change my mind and do something else wit it too :oP

Forgot to post what I got!

I'm making a very simple breakout board for Nordic's Bluetooth 4 Low Energy chip - nRF8001
Eagle files and BOM: https://github.com/nabilt/nRF8001-Breakout-Board (https://github.com/nabilt/nRF8001-Breakout-Board)

Not backwards compatible with older Bluetooth devices like (e.g. v2.1), but everyone seems to be moving in this direction. If it works out I plan to use this for most of my wireless projects going forward.

They claim:
 - it lasts years on coin cell
 - 50m range
 -  1Mbps over the air data rate; 0.2 Mbps throughput

@Kartik,
There was no customs for the things I received last week from china. 1. SeeedStudio PCB. 2. the above resistor kit.

In my life I only paid for customs once that was for the $4.30 valued MSP430 launchpad. And I had to pay Rs. 483 or almost $10 for the fees.

I wonder why you(Kartik) don't respond to my emails.

Bought a Proxxon Micromot 50/E for € 34,95 (Has variable speed control.Comes with 6 triple slit steel collets.)

[attachment=0]

I used a 2A transformer with a full bridge rectifier for the 12V DC. The speed control uses a NEC 2P4M thyristor. Hence, no capacitor or regulator should be used for variable speed control to work.

Lots of stuff came today. My Mouser order which includes some parts for personal and Dangerous Prototypes projects (also some parts for friends, but I separated them before taking the picture), eBay order which has 1.8" TFT modules, uSD card holders (I hate Microchip SD card library, it is not uSD compatible as it needs Write Enable and Card Detect signals from card holder which are not present on uSD card holders, but managed to hack the hardware definitions :) ) and some rework wire. Also I bought a 1.4" TFT breakout with an SD card slot at the back (also does not have the above signals broken out) for messing around. Here are the pics:

I got a Chinese Owon 7102 scope ...:D

bad first
i discover i have a faulty probe,  when the probe lays flat no problem,  but a really small bend in one direction and i got  noise ....  1 new probe is suppose to be in the post for me.

i have also a stuck on green pixel !  it needs at least 3 to be a defect lcd seller and company said ... 
i'm kind of disappointed a bit because of that ...

good news
that the scope is kind of good for what i  want to do at a decent price :-)

and  it is fun to have a scope !  :P
here a small video of PWM of an hbridge in red  and voltage of the neg pole of the motor in yellow.
it is a small low standard no torque 50mA motor, i choose the worst possible trace and speed for noise ...
for sure this bridge need more study :-)

@Tayken - I'd avoid the Microchip SD card library if possible. There are a bunch of easily portable open source versions floating around. I think the first link in the equivalence table is the one I wanted to try most recently:

This is the purchase I've been most excited about. It's a decent light box (not fancy, not super), just better then when we had (nothing). Still needs some work to hold the DSLR properly on the overhead bracket.

Yep, they have lots of problems with that. I also have to use the TCP/IP stack so I am weighting my options for now. I have a method for hacking the stack (by changing defines, not a biggie) but I am not sure...

cool :)

i just received my little clock / square wave board adjustable from 1Khz to 33MHz
it is base on LTC1799  and for the price it is pretty good, real decent SW until 5MHz
SW rising edge is a bit cut at 10 MHz and it becomes rapidly a triangle wave until 30MHz ...
freq seems pretty stable and near no noise. 
they design is really simple and  it seems a real keeper to include in my future projects  :o)

 i was using my BusPirate as clock , but i need it in more useful place than just a clock :-)

You know how hard it is to choose the right conector when all you have is an online catalog and well TE Conectivity (via Digikey) sent me a sample pack of their sotutions for SSL http://www.te.com/en/industries/lighting.html (http://www.te.com/en/industries/lighting.html)

BTW I cant believe UPS took a month to deliver this package, it's even slower than the Postal Office!!

There are some pics

I really like the solder less LED sockets.

I also liked this conectors, really easy to asemble and join wires.

When I got it, the small flat cable was missing. Instead, there were two of the "squid" cables with loose pin connectors. The flat cable is handier in most cases, as you can unplug the tool easier. So, I wrote to Digi-Key asking for one. I said is not a big deal and I don't want to return it, as I need to use the tool more than I need the missing part. They decided to send me another one for free and said to keep the first one, too. So, for a missing 2€ cable I got a free 200€ tool. It will be handy when I build a two processor something. :)

Reviving the old, but fun thread -or am I the only one getting new toys? Yesterday, I ordered:

A) A three output programmable power supply with V and A meters on all outputs. You would think there are more products that do this, but I really find only one affordable product, ATTEN PPS3203T ( a 5A model exist, but 3A is plenty for my purposes):

I wasn't going to suggest that....... does your supply auto switch from CC to CV?  If those batts burn, I don't think that plastic tray will save you!  RC guys charge in fire-proof boxes.  I never leave them unattended.  I have heard too many stories of people who left them and went out only to come home to fire damage.

I wasn't going to suggest that....... does your supply auto switch from CC to CV?  If those batts burn, I don't think that plastic tray will save you!  RC guys charge in fire-proof boxes.  I never leave them unattended.  I have heard too many stories of people who left them and went out only to come home to fire damage.[/quote]

I got one like this one, i hope it will do a good charging job (correct CC CV curve/switch) ... i might take some measurements of theses parameters ...  (i only own a  crap pc hack power supply,  no current control, so no good)  ...

The batts never leave my sight whenever its recharging. Well all I can say it's as safe as they know what they are doing. Im doing this way until my hobby charger arrives.
Safety is always a questionable issue with those ebay charger. I saw Imax b6 charger going as low as $19 where my local retailer is selling at $38.

Couldn't help myself... Bought some IN7b and IN15b symbol nixies. I came back from Maker Faire all charged up about them and hit ebay for IN2 sockets and ended up with 15 new tubes :D Numbers are more and more expensive (clocks), but the symbol tubes are cheap cause nobody wants them. Well I want them, they're my favorites!

Allright!  I've got the same microscope!  I bought it with both the x10 and x20 eyepices, but I'm only using the x10 and I wish that I selected 5x and 10x instead...

It's a rather nice microscope, but the built-in light is a total piece of junk - it got all the brightness of a cigarette lighter :-) So I currently use a IKEA LED lamp.  Maybe some day I'll make some better solution for the lightning...

I have that too. I too added some lamps. To be able to work on some big boards that I have, I had to the base around to make a bigger work area. Of course, this made it necessary to use a high tech microscope stbilizing device (i.e. a stone) on top of the base. I could have used the industrial made super high tech product (a brick), but the stone look nicer and reminds me to keep the down to earth attitude.

I agree with all the light comments, the included light is more useful as a hand warmer than an actual light. :P I mean, it gets hot, VERY hot, after only ten minute of use. I am going to stick a high power led in there or make my own led ring thing for this microscope.

Also, one bad thing about this microscope is that it falls over if you rotate it too far. I will also think up of some extremely advanced method of keeping it up right! And for some reason the left eyepiece fogs up after a few minutes of looking through, while the right one stays fine, it is so weird.

How much did you guys pay for yours? Mine was $200, hopefully I did not get ripped off, but it does seem to be high quality, with the all metal construction and whatnot.

And lastly, I got the one that has the 5x eyepieces and 10x eyepieces, but I will email the company in hopes of exchanging the 10x eye pieces for the 40x eye pieces, which cost only four dollars more.
Title: Re: I just bought this, and you what did you buy ?
Post by: matseng on October 14, 2012, 11:20:41 am
I bought mine from eBay back in 2009 and paid $180 for the scope plus $109 for the shipping to Dubai.  So it seems to be about the same price today.

40x?  Are you going to do surgery on fruit flies or something like that? My x10 gives me a very narrow field of view, I can't image how it would be just seeing 1/4 of that on the PCB...
Title: Re: I just bought this, and you what did you buy ?
Post by: hak8or on October 14, 2012, 07:27:57 pm
I want to be able to eventually look at chips I decap. :P Besides, I will still have the 5x eye pieces, so I can use that for more general stuff. Not to mention that I have a larger interest in photo lithography for not only PCB's but super small stuff, in the hundreds of nano meters

Though, I think I may need even higher magnification for that...

I recently got a stereo scope (used leica for sub $200) and love it, makes SMD work nearly trivial. Only thing it does not have a light source, so I need to come up with a good solution to that, on the cheap of course...
Title: Re: Stereo microscope
Post by: jolshefsky on October 15, 2012, 04:24:31 pm
On the stereo microscope, how's the depth of field (how tall can an object be so the top and bottom are in clear focus?) and the field of view (can you move your eyes to look around the view or is it like looking through a soda straw?)

I use a loupe to see the writing on SMD's but the depth of field is only a couple millimeters so it's only good for inspection, not close-up work. I also have a swing-arm magnifying glass with lower magnification (with that it has a deeper depth-of-field, and of course the field-of-view is quite large) that's pretty good, but the swing-arm setup is not ideal to move around.
Title: Re: I just bought this, and you what did you buy ?
Post by: hak8or on October 15, 2012, 10:20:37 pm
I am eagerly awaiting a review of the power supply, and hopefully a teardown of sorts! :P Do you have an oscilloscope, and if so, will you use it to see the ripple on the power supply?

For the headphone amplifier, do you use any hi-fi ish headphones like the 595's? The THD seems a bit low, at 0.01 %, but I have yet to actually test if I myself can hear the difference between 0.05% vs 0.002%.

And for the microscope, I feel terrible for having such a bad picture end up on the front page of DP! I will try to get a better picture later today when I get back from class. The DOF seems to be perfectly adequate for soldering, though at 20x magnification your hand jitters become a major visible problem. So, the DOF seems to be maybe half thickness of a plain 0603 resistor. I will give you a measurement later today if you want me to. the FOV is not too large, but you can move your eyes a bit to see everything. It is nowhere like looking through a soda straw though. Off the top of my head, I think the FOV would be maybe 2/5th of what is possible with one eye looking forwards. I don't really know how to give you a FOV number or comparison, sorry. But it is enough to easily see a good bit of a 0603 component and the surrounding PCB.

For reading the letters on IC's I do not think a stereo microscope is what you want. A major component of seeing the letters is the angle of light, and with this microscope that I bought you can change the angle of light only a little. I use this,
(http://http://ecx.images-amazon.com/images/I/411OWkRPFxL._SL500_AA300_.jpg)
http://www.amazon.com/Pocket-Microscope ... =loupe+60x (http://www.amazon.com/Pocket-Microscope-Jeweler-Magnifier-Adjustable/dp/B0053VJEL2/ref=sr_1_3?ie=UTF8&qid=1350332362&sr=8-3&keywords=loupe+60x), for magnification of letters and small stuff. The working distance is horrific, but the light is extremely powerful and magnification is quite high, so it is worth a shot to try out, especially given how cheap it is.

Post by: JuKu on October 16, 2012, 08:00:28 am
Looking again, there are some slight differences, so I might not have the exact same unit. Mine is a C2-D microscope from GX Optical (in US, they are called GT Vision). I paid about 230 UK pounds, including shipping, about a year ago. Anyway, I use 5x for hand SMD work, and I find that to be ideal: magnification is big enough that the limiting factor is my hand, not seeing what I'm doing, and the field is big enough. The optical quality is good, never felt that limited by that. I actually went down to my cellar lab and took some measurements. Using 5x:
Width of vision: 30mm max, 15-20mm usable (not a Mantis but quite ok. Still, you never have enough)
Depth of vision: 10mm sharp, blurry but usable about 25mm (more than enough)
Vertical work room under the lens: 200mm (great!)
After turning and stabilizing the base, 200mm horizontal work room to the base. (In other words, if I have a board 500x500mm board, I can't work at the center using he microscope. Hasn't happen yet.)

I'm still happy with the unit.

First up is some RAM. It may look flimsy and cheap, but thanks to Samsung's 30nm process used for these DDR RAM chips, you can easily overclock them to at least 2 ghz with a small bump in voltage and still have tight timings. This is a little secret of the RAM world, as these are also rather cheap.

This made a huge difference when i finally switched from a clothes iron (I found a GBC laminator on ebay).  To get mine to accept PCB's , I only had to take off the cover.  The rollers are on some really strong springs which have a fair amount of travel.  At first, I was putting a little piece of wire between them (and not bunch up the paper), but with thicker photo paper, this turned out to be unnecessary.

This one feeds 1.6mm boards just fine but the temperature is too low.

The bi-metallic thermostat is a 102C (215F) -version so I'll probably just replace it with a small uC using a diode as tempsensor together  transformerless power supply and a triac for bang-bang regulation - should be easy.

I'm not sure what the limit of the thermal fuse is, it probably needs to to be replaced with a higher temp fuse or removed altogether. The laminator will be supervised when in use so I really don't care about the possible fire hazard...

cool I received Monday my new Mega 2560 from Seeed !

so here the story, i'm working (very) slowly on a little project where i need a small  hbrige and few io, 
so long time ago i got one clone Mega1280 ... it sat in the drawer for a while and i started to use it
with the hbrige project ... 

I look at Atmega1280's spec and i was please with the 6 timers available, so my thoughts were, to use
counters 4 and 5 to count external io events ... 

so... DUH ! what the hell ! 
the arduino mega 1280 and 2560 don't have all cpu pins connected to headers!
rendering 2 timers blinds of external events  !

that is not good in my "open" hardware set of rules / wishes ...
-giving access to all cpu function pins is a must !
what the hell ! 

so i start to look around and found Seeed Studio Mega2560
witch has all pins routed to headers ! and keep the standart Uno header layout.
so i spent $$$ and got it ...
so i guest my next move will be soldering headers tonight :-)

so again please keep in mind that "open" products are more fun when they are versatile and hackable  :o)

The soldering iron kit was $249 free shipping with the two tip it came to $277.46. The tip are T15-1603 and T15-ILS , yes they are tiny. I can tell you right now that the iron gets hot quick! The sleep mode is great and it recovers fast. This is the best iron I've ever had. Bought the kit from http://http://www.bdent.com/105-TL-FX9516-p/105-tl-fx9516.htm

Any specific reason why you bought it from bdent instead of amazon? They both have free shipping and the same price, but amazon has legendary customer service and most likely no tax in this situation, unless you are in California.

For some reason, I can't get around the coloring making it look like a toy. I am still using a cheap $15 soldering iron from radioshack! :)

I guess it's loyalty to the company . If someone treats me right I'll keep coming back. It's not alway about money,  product knowledge is also a must. I deal with Tom  all the time , good individual to work with. The color is a little to close to purple for me but the quality is outstanding.

I just got 25 pcs of ATXMEGA32A4 shipped to me from USA by a member in this forum - I won't mention who it is because officially one need an export license to ship them out of USA.  It's really ridiculous since it's just a 8-bit AVR with USB and a encryption module, you can do faster encryption on a FPGA that you can purchase without an export licnese....

These will go into my KimCard / KIM-1 clone project and I won't even use the encryption part of it - only the usb module. The ATXMEGA32D4 is the same chip but without usb & encryption. Why can't they do a model where only the encryption is removed?  The A4 and D4 chips are about the same price anyways so it can't be out of cost reasons.

Anyho... Thank you Mr. Z for your help.

A box with three partitions and a 100-pack of rather thick and sturdy envelopes that has the flap on one of the short edges instead of the top.  The flaps will be closed and the envelopes cut in half height.

I'll use these to sort smaller parts into - I'm sick and tired of having hundreds of bags from Element14 in random piles...

They're the ones that DP featured when they went on sale (http://dangerousprototypes.com/2012/09/ ... ev-boards/ (http://dangerousprototypes.com/2012/09/19/latticesemi-offers-discounted-fpga-dev-boards/)).

Opamp, dc-dc converter, audio amplifier, some 0603 capacitors.

All these bought from SM Electronics, who is Indian distributor for Mouser. Buying directly from mouser attracts $40 shipping, tension of customs, etc. Buying from them attracts little charge and it's good for small orders. My current order was near $10-12  only.

Picked up this at SEG market @ Shenzhen with the help from Eric at Seeedstudio.

5 meter of addressable RGB LEDs with PWM in waterproof flexi strip for 150 RMB = USD 24 total.  Adafruit charges 150 USD for 5 meters of a similar strip (about 30 leds per meter).  This strip got LPD6803S as the LED controller chips.

Three full reels each with 3000 pcs of 0805 leds, red, green and yellow... 513 RMB = 82 USD in total.  Eric was not too happy about the price but I accepted it anyways...

I finally received my encoder from Ebay :o) 
and I send a message for the seller for the datasheet last week ....
until now no answer,  so I think few people here already used them ...
I know it is 2 bits gray code plus a switch so it will be easy to find out, but still
having the specs will be nice ... 

do you have the datasheet handy ?

I also remember to see an eagle part in the blog,  was it done for those litte encoder ?

I also ordered a bunch of stuff from ebay, so I will get few Xmas packages in my mailbox :o)

A very good microbiology textbook for only 12 bucks including shipping. Used, one edition old (basically a year old), and quite a bit of highlighting.
An iphone 5 for 200 which I will flip for around 700, netting me 500 bucks which will go towards a proper biology microscope, like one of these:
http://www.amazon.com/gp/product/B004X3 ... d_i=507846 (http://www.amazon.com/gp/product/B004X3QWZW/ref=s9_simh_gw_p328_d0_i5?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-5&pf_rd_r=0Q4Z7Y5ZB8TD5Y1YGFSM&pf_rd_t=101&pf_rd_p=470938811&pf_rd_i=507846)

or this guy if I find a similar one on ebay:
http://www.ebay.com/itm/amScope-40x-200 ... 7675.l2557 (http://www.ebay.com/itm/amScope-40x-2000x-compound-binocular-microscope-w-camera-/121025069947?nma=true&si=hljxjC%2Ff7FnbVUG964Odui6AdtU%3D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557)

And the rest of the money will go towards paying off my parents mortgage. A pretty good "investment" considering it will give me a good yield, tax free, and 100% safe! Yes, paying off a mortgage early can be considered an investment.

And here comes the tiny thing in the bottom of the picture, my PCB's from OSH park. The guy or gal there is extremely helpful, helped me out by telling me which files I should generate from altium, and even canceled an order of mine by request after it was panelized! I will be doing all my PCB buys from OSH park from now on.

Only eight bucks for the used version, versus over a 100 for one edition, or one year newer version. I despise publishers and their relation ship with schools. Nowhere near enough new things have been discovered or changed to warrant the necessity to buy a newer edition for over 100 dollars.

I ran into the same thing, funny thing is ohms law(and many others) has not changed at all in my lifetime. I once went a whole year without buying new text books, or old ones for that matter. I borrowed some 25 year old books at the time and was 95% covered.

I usually end up buying the used book "bundles" from my school, we have to buy activation codes for all the "Mastering$CLASS" and such anyway. It's ridiculous, entire departments are wrapped up in Pearson's web. </fightthepower>

I do not want to say what they are meant for yet, as I want it to be a interesting surprise thing, so instead here is a picture me messing around with them! Sadly I have my final exams now, so this will be left alone for the next week or two. :(
[attachment=4]

And testing out photo stacking. I originally wanted to do it in gimp but then found a free program which does all the masking, re positioning, and other stuff for me. This is a cracked piezo up close under the microscope.
[attachment=3]

Off topic: I finally sold the Iphone 5, via ebay, making a cool $375 ish after all the fees and whatnot, and I should be getting access to my funds in a few days! Still debating a 3d printer like the makibox vs a kick ass biological microscope. I would add it to my savings, but damn curiosity and eagerness. :P

And yeah, at my college they do this thing where you need an activation code to do courses and exams online through either web assign or some other garbage. Don't have the code? No homework credit for you, and sometimes you don't get to do the exams, which essentially means you fail the course or pass it just barely. This happened for my intro to psychology course. And if you want to just buy the code, it costs more than the text book with the code. And guess what, the ebook version costs the EXACT same as the printed version. For some classes you need the code only for the homework, which is usually at least 10% of your full grade, normally it is from 15% to a 1/4 of your grade though. For classes which do not use the online code, the books generally cost less than thirty dollars because people are reselling the old versions, while the books with the code generally cost 100$ and up. The funniest part? When you get the print version, you get the ebook version included. The company that seems most at fault for this is Pearson, so now what I do out of hatred of them is just buy the book, look at the free included ebook version on their website, and download the entire book. What I do further with it I cannot comment on this site, but I can safely say that I am quite sure it violates their TOS. >:l Screw Pearson and my university for such garbage!

Also, I think I am derailing this thread, sorry guys!

Edit:
To keep this on track, I took some pictures of what I got in the mail a while ago.

I don't remember ordering this or anything. I didn't even get a chance to look through it properly yet, but with a quick glance I did not see any nice pictures. :(

Nope :) That does give me something really interesting to try out though! I did not even think of such an application for these!

Indeed. :P Omnidirectional speaker or mic would be interesting, but I would be missing a mic for the above area because the middle piezo would probably block sound from above, and the side pizeo would also block sound for the lower piezo. Good idea though!

I should have given more info earlier, but the piezos are wired fully separately. This was my first attempt, and it failed horrifically, for two key reasons. First was because of a totally obvious design flaw, and second because it kept falling apart. Hot glue sucks for this. :( My second attempt also used hot glue, which also fell apart. The application of what I am trying to do is minuscule. Ok, no more hints or anything of the sort, or else someone will actually guess this. :P

Anyways, here is yet another thing I got in the mail a while ago! I learned that these magazines information on computer related things leaves something to be desired compared to magazines like maximum pc.

Anyone know what happens if it is opened but not used before the date listed? First time I ever saw anything like this.

Anyways, I might be getting myself a Rigol scope instead of the 3d printer. Makibox decided to jack up their cheapest shipping (via cargo ship, month wait) price to 128 damn dollars from the original 28 dollars. So instead, I am looking at getting a new scope, as my current analog one is starting to be less useful. I want my FFT, automatic duty cycle calculating, the ability to save my waveform, and save the image on the screen itself.

And on a unrelated note, I finally got a blog thing up on my site! I am changing all the nav's to be done with with PHP instead of html, so I only need to change it once and have it propgate to all pages, instead of changing it manually on each page.

If you don't follow the instructions on the package (only applicable if you're assembling via reflow) then you risk blowing the package of the device.  Plastic cased IC's absorb the humidity from the air, when the entire package is heated, the moisture can boil and cause damage to the IC package (known as the popcorn effect (http://http://en.wikipedia.org/wiki/Mobile_device_forensics#Forensic_desoldering)).  This is less of an issue if you're hand assembling with a soldering iron since you're not heating the entire package, but mainly the leads.

I went to IKEA to look at work tables, as I need a new table for a new project, and my cellar lab had room for one. I went at lunch time, and ate lunch first. While eating, I paid attention to the table I was sitting at. Turned out it was the sturdiest of what they had, and they had an offer on it, too. :)

Got this last week and it's a nice little toy to go along with the FX-951 that I bought a while back. Great little buy for $14  new, free shipping from China on ebay, probably Chinese version. The label on the back does say made in Japan.

Does it give you correct temperatures?, I bought the previous model, 191, seems to give correct temperature-reading, but my fx951 (which obviously is an clone, again) does not give me correct temperature.. set it to 300 and I get 310-320, if I set it to 340 I get 380-400, which is way off..

@neslekkim,
My FX-951 is with in +- 5%  at or above 380deg that is checking with the FG-100. I bought the FX-951 from a US distributor, so I would think that it is the real thing. I hope. I seem to remember seeing a calibration certificate in the box, I'll try and look for it.

I even have an transformer for 110 and 220volt.. and I bought it from an US distributor myself, and paid $240 for it.

Seems to be about the same... But your's much cheaper. $6 for 100 pcs vs  $5 for 10 pcs :-)  But I only have use for a few so I really don't mind.

I don't have the fixture yet, I'm just preparing for the day I'll actually get one....

yes, i hope it's the same, not bad for this piece of metal.  Couldnt find anything on ebay to use these dowels for, but i bought 2.5mm and 3mm packages.
Not sure if i can use those 3mm, but since DP SoB cases and boards use 3mm (I think?), I wonder if I can make an easy jig for sanding multiple boards, but 100 is kinda.. a lot. :)
Title: Re: I just bought this, and you what did you buy ?
Post by: matseng on January 16, 2013, 03:19:53 pm
Good idea with the 3mm dowels. Ideally they should be 3.2 mm since the holes in the SoB pcbs are 3.2, but 3.0 is probably just fine as well.

It's really strange that I can find your dowels when I search eBay.  The item is named "100 Pcs Stainless Steel 2.5mm x 15.8mm Dowel Pins Fasten Elements" but when I search for 2.5mm dowel it doesn't come up in the result list.  No wonder I had to purchase the expensive ones from UK.

Mats I just searched for "2.5mm dowel" and found the same UK x 10 listings, but if I keep scrolling down it has an ad area and then shows the international listings, where the x100 cheap ones are.  Perhaps you didn't scroll down far enough or maybe your settings are not set how you want them?

No, it's actually nothing - or at least as little as possible :-)  It's just a slight indentation / groove caused by removing the soldermask there so the pcb is bare. Like this....

SockiSop looks good. Did you put the number (order number?) on yourself or did they do that?  With mine they've always done it by making the text a negative in the solder mask, so it's hardly noticeable. That's a lot of LCD displays! Do you have a use in mind, or just getting some cheap stock up?

Negative soldermask text?  That would be really nice, but I've never seen that from Seeed on any of my like 25-30 different board designs they've made for me.

The first few boards I actually put the Dxxxx-order number on myself as according to their instructions, but they always ignored it and put their own stuff elsewhere on the board so I stopped doing that.

The LCD's are not for any particular project, except for doing a breakout as we discussed in the Cheap Nokia LCD thread. And as usual I go for a decent sized lot of whatever I buy if the total price is not too high.  This lot were like $1.85 each inclusive shipping compared to the $3.50-$4.50 if I just would have gotten a single lcd from another seller.

Some random cheap crap from eBay.  A few weeks ago bid on, and won, a lot of low cost free shipping auctions.  I set a max bid of either $0.99 or $1.26 depending on the item on about 300 auctions over the course of a few days and in about 25 of them I was the winner.

This was waiting for me when I got back home from my trip. I expect some more crap to turn up in the next week or two. Not all items here was less than $1.26, for instance the DDS modules I got at the regular buy-it-now price of $4.50 each with free shipping.

Those hubs look suspiciously like the ones I bought to dismantle for inside a TL-WR703n - if they are, then I found that they have no visible xtal, and stop working after 6+ hours (which is bad when your root drive is on usb...) - I suspect due to timing drift.

Still, I like the idea of throwaway bidding on random junk... :)

Heh, I got 100 of those magnets last year, They work great, but are so small they latch onto your tools without noticing and stick to everything else. I think the envelop they came in was stuck to my mailbox pretty good.

A couple months ago I picked up a roll of the RGB LED strip with the little control box and remote from eBay. The LED strip looks nice, but the remote basically sucks. It really wants to stay in the fast flashing crazy mode and will only stay on a few colors. I'm making my own controller anyways as part of an aquarium project.

Well these actually got a 12MHzc rystal mounted at the bottom of the single sided pcb. It's really incredible to see a 4 port hub with so few parts. I've got a some 4-port hubs that are a few years old and they have 4 or 5 ic's and more like 50 discretes in them.

Wow -- how were those packaged and shipped. I wonder if they stick the machines an mess everything up?
[/quote]
They're really really tiny, so 500 of them is about the same size as 1.5 sugar cubes. So they were just wrapped in some bubble wrapper and then put in a regular envelope.  But at close range they are really strong. I put all of them in a line and hold on to the top one it can carry the weight of the remaining 499. One of them can easily hold a A4/Letter sized paper on the fridge.

Yea, I'm not surprised.  I got these boards to use for parts for building my own board and it was cheaper to get these from ebay than purchasing the 125 MHz oscillator and the AD9850 at my local Element14/Farnell. :-)

I just picked this up at my local surplus shop.  The gallon size bag contains mostly these values: 470uF, 220uF, 100uF, 47uF, 22uF and 10uF.  I estimate the number of caps totals around 450-500, I'll take inventory later.  I saw it and had to pick it up.  It's funny because I was just pricing parts for one of my projects and I needed 470uF and 100uF smd caps so this works out perfectly for me and saves me the shipping time.

That binary explorer board looks pretty cool!

While getting a Garmin Nuvi 50LM GPS for a upcoming roadtrip I couldn't resist also picking up a 199 Ringgit (USD 63) Android Tablet just to see if something priced at a 1/10th of an iPad actually is usable at all.

It turned out that it is not a total piece of shit so my wife adopted before I had a real chance of actually testing it properly.  :-) or :-(  Don't know what smilie that is best here...

I have to go back and get one for me as well.

I recently bought this same "cheap" tablet. I thought I will use it on my wall as a huge light switch to manage all my light in the living room and kitchen.

After playing around a while I think that except the viewing angle of the display (which is total crap) the tablet is amazingly usable.

Even when I just switch lights on and off occasionally the battery lasted 10 days!! I was shocked to see this with a cheap Chinese pad.

I also use a Nexus 7 which is of course better, but I have to say the cheap one is nice, too. :)

I recently got myself a signal generator, the Siglent SDG1025 to be exact. I am not sure how long Siglent has been around, but I had not heard of them before. However, they make some really nice gear. They even had a booth at Electronica.
So far I'm really happy with signal generator. It can generate sinus, rectangle, sawtooth, pulse and noise out of the box. It also has some preprogrammed arbitrary waveforms, but you can also generate your own. The software that comes with the device is ok, but not great. As waveforms are saved as CSV files, it is easy to generate them. I wrote a short script for this task and it worked flawlessly. I tried to measure THD and 50dB @ 100kHz was the best I got (this was the first time I worked with a spectrum analyzer, so the actual value is most likely better).

[quote author="matseng"]Picked up this at SEG market @ Shenzhen with the help from Eric at Seeedstudio  - 5 meter of addressable RGB LEDs with PWM in waterproof flexi strip for 150 RMB = USD 24 total.  Adafruit charges 150 USD for 5 meters of a similar strip (about 30 leds per meter).  This strip got LPD6803S as the LED controller chips.

[attachment=1]
[/quote]
After being put in a box for the last six months I finally took a closer look at my led strip and found out the reason for it being so cheap (1/6th of the Adafruit price).  There are only 50 controller chips in this 150 led strip and each chip can only handle one RGB led. 

So the leds are connected in groups of three and can not be individually controlled within the group.  :'(

But it will still be enough (50 controllable segment/groups) to make a 1-dimensional Pong game with piezoelectric foot stomp boxes....

I've never used the crown-style pogopins, only the pointy ones.  Are the crown-style better and/or easier to use?

crowns are suppose to provide better contact than the points (they're also generally more expensive when buying from "normal" distributors).  I use them for test fixtures - they're good for hitting surface mount test points but also do a good job of straddling small vias in the center of PTH test points.

If you use chrome, you get the question if you want to translate the page. It does a decent job, and most of the things will be unerstandable. Be aware the Yuan (RMB) symbol will be replaced by a $ symbol. When I was in china I used for converting it to EUR I divide it by 7. Later I understand the power of showing a calculator to the seller and type obscure calculations ;)

I noticed it is 8 for EUR now and 6 for USD. Use the xe.com link to be sure or for your currency.

Those times I have used Taobao (mostly for Atten soldering stuff and component rolls) then they have used Alipay. Alipay takes Visa and mastercard AFAIK.

Today I got 9 ARM LPC1111 Cortex-M0 processors.  I got the entire tray for only 9 chips. Luckily Element14 have free overnight courier shipping to me so I don't care about the extra shipping costs :-)

Even if I had to repair it twice my old AVRDragon had served me well for a few years by now.  But two days ago it finally gave up its final (dragon)breath. The control of the Reset-line stopped working and I haven't been able to find the cause yet, so I got myself a new Dragon for the time being. Maybe I can resurrect the old one some day....

cool, I went crazy in january and also bought lot of sound chips:
SMC0608S, YM2203C, SAA1099P, YM3014B, YM3012, SN76477N, AY-3-8910, SID 6581
Took very long before I got them so I lost the idea thought, but I guess you come up with something soon?

I also bought various dac's, not sure if they are usable but:
YM3016-D, PCM61P, MCP4921, DIR9001, TDA1543, YM3016-D

and after finding this:

I was sold on the MSGEQ7 also.. but still not used, as with most :)

I only planned to get the AY-3-8912's but some other good-to-have junk appeared  "almost by itself" in the shopping cart. :-)
 
I'm not 100% sure of what I'll use them for.  Either as a sound module for my Pling-Plong synth, or I'll just cobble up a standalone player/editor with a LCD display and some buttons...  Maybe both.

I have 7 of these https://www.tindie.com/products/FriedCi ... trix-link/ (https://www.tindie.com/products/FriedCircuits/led-matrix-link/)  and some other matrixes laying around, my grand scheme is to make an wakeup alarm clock, with radio (If I ever find out how to get some DAB+ thingy connected), maybe i can use the MSGEQ7 with an microphone to do an snoring detector also? :)

SN76477 - Wow! Haven't heard that code since...          well, lets not go there! I'm amazed you were able to get one, I recall them being hard to get even when they were around. And both of you having the old AY-... chips from GI. I still use AY-... keyboard stuff (have a PDF somewhere on it). From memory that stuff became hard to get way back then because the General Instruments (GI) factory burnt down or something like that (at least that was the rumour at the time). Apparently Microchip and the first PIC was a spinoff from GI!
http://http://en.wikipedia.org/wiki/General_Instrument
I still have an old Pong Game (somewhere!) I built with the AY-3-8500 http://http://www.pong-story.com/gi.htm and http://http://en.wikipedia.org/wiki/AY-3-8500 built from an old ETI magazine design (which also had a design for the SN76477 as I recall). I recall finding it 10 or so years ago and wondering how on Earth it managed to work, with a homemade Bakelite board cut with a pair of tin snips, hand etched and hand drilled and rather 'questionable' soldering, (long before I was trained). I thought it was a 40 pin, but apparently it was only 28pin. There was a later project for a skeet shooting type project to add on to it, which I think used a photo-transistor.

make something so I could read midi from my keyboard and use these chips as soundgenerator would be cool, but I'm not sure how easy they are to use. (And I'm not an musician by a long shot, only find it amusing to make some noise.. )

I probably should have specifed 'Qwerty' Keyboard, not musical keyboard - lol.  But you could probably interface the SN76477 to some interface to midi. I wouldn't know though, don't think I ever ended up actually getting hold of one back in the day.

People have made interfaces to midikeyboard using arduino and smaller chips, so I don't think that should be the biggest problem. At least for me, since I don't know notes ;)
But I have the papilio fpga with retrocade that have zpuino sketches for midi playing using sid chips etc, but that is all fpga, interfacing through real chips is otherwise, but someone started an thread now interfacing real chips:

I got a pretty lamp frame from the dumpster few weeks ago, "the electronics" is burn by I like the frame  design ...
so yesterday I got few 4 leds square ($1.50each)  and a switch from the surplus store nearby :o)
I have few 12volt dc adapter laying around so I will reused one of them.

Tests,
2 squares will be enough, each square need 12v and 75mA.

so this week I will take some time to drill some holes, build some bracket, wire few things .... 
and maybe have a new dumpster lamp !!
