Dangerous component/part tester

Postby BrentBXR » Sat Dec 10, 2011 7:57 pm

check this out:

http://www.youtube.com/watch?v=8UgL53mt ... re=related

its a component tester; you can put the component in any way you like (just connect the pins and hit the button) and it will tell you what component it is; and its stats, along with what color pin is connect to what pin on the component (eg: NPN transistor; EMT=GRN; BASE=RED; COL=PURPLE)

is that sweet? there is also an AVR based one:

That would be sweet DP product

Dogsbody:

I'd also prefer keeping a SPI connection, since its 50-100X faster than serial


I´m lost in translation, who ask for replace the SPI and use USART transmitting? I think that SPI it´s the only one cheap (free) alternative when we need fast and cheap serial download or control. I used PCI and PCIe and was very challenging but powerfull and involved a lot of trial and error to polish the board for high speed noise. I use USB at max speed or ethernet at 100Mbit and was more easy than PCI in most of cases but I prefer for small distances SPI. Have you ever design something with PXI?

I'm not sure how SPI is any faster than 'serial'. SPI is serial, just synchronously clocked. Most UARTs today will run well into the mega-bit/s range even with 16x over-sampling.

However if you need to transfer a lot of data, using the 8 bit FIFO interfaces built into the FTDI FT232H, FT2232H, and Cypress FX2LP high speed USB devices can't be beat. All three can deliver over 20 MBytes/s.

This component tester is a great project ... do you know the home page of that avr based one ?

Great, thanks, I also found: http://www.mikrocontroller.net/articles ... stortester

not sure if they are identical .. checking them out - very interesting .. was thinking of making something like this for a long time ..

I think this is it:

Its in german; perhaps Ian can read it :3 Im half german (used to live in den-haag (the hague; Netherlands) but all I know is no, good morning, stuff like that lol.

google translate works ok and I do know a bit of german so not a big deal ... this looks very interesting, single side board, nice firmware written in c (no asm shit) .. I think I'm making this "asap" :)

:) Me too. Will do it on protoboard to save PCB fabrication time.

You guys should start a project log; I would be interested to see how it turns out. Are you starting from scratch and just taking ideas and principles from the AVR project? Or are you just re-creating? Either way im sure you will put your own twist and/or modifiy and upgrade where possible.

so please create a project log! If it turns out pretty sweet I will make one too. Infact; if it comes out really sweet; we should all pitch in on getting some PCBS built and split the boards; anyone who wants one can get one for cheap! that would be sweet! Hell if it comes out super super sweet; we may even be able to get DP to jump on the bandwagon and design it with there twist! which you know would be sweet! I would like to see the BP do this... Although; once you start having the BP do stuff like that then all of a sudden it should do this and that too; and you end up getting far far away from what it was and is supposed to be. So I guess a line should be drawn; but thats for Ian to decide of course. Im guessing its for protocol and communication only and Ian has already set that line; but who knows! He may want to expand it...

some lazy calculations; if we kept the board at or under 5cm x 15cm and got the board non-green; we could each get ~3 boards for 15bucks. thats pretty darn good. If we got 5 ppl total; it would be under 10 bucks each :D and of course we would always get it green, then we are talking even cheaper! (I want an un-populated PCB so bad :( I cant win one and have no project ideas to make one.... its killing mee. Ordered two differnt kinds of flux; I bought super slim soilder and even a sharper iron tip... i want to try SMD so badddddddddd. iv all but given up on the PCB drawer, now im looking for left overs or new ideas! I wish Ian sold all his PCBS (as an option; free and/or purchase! that would be sweet.)

I will just make "identical" pcb and recompile firmware with changes to strings (as I seen some strings are czech or polish or something like that) but that's all, the pcb is as simple as it can be, it's single sided, and it works ... I don't see a reason to add a "twist" :) and don't have time to design it myself (I will of course look trough firmware as I'm interested in principle of operation :D ) but this looks like "better version of super probe"

can you make me one too? I will compensate you for time and material. I do not have the materials to design PCBs anymore. I dislike etching; so I usually just protoboard these days because I dont have drills and stuff like that to really make a good etched PCB. I live in an apartment; I dont have the space nor the area to drill without annoying neighbors...)

If you could duplicate it and make 2; i would really appreciate it (un-populated is fine; if you could drill where needed that would be sweet. but i will take care of components and compensate (paypal? or other method? let me know)..

Infact; perhaps we could help each other. If you design the PCB I can go through the firmware and fix any translations needed... I dont know enough to update it and make it work *better* yet. but I might be able to save you some time.and compensate (dont want to leave that out. Im not one of those broke hobbiest; i actually make great money for my age. So im serious)

I think I will also pay someone to make pcb's for me (Arakis or someone else), I just don't have the nerves to be honest, neither for etching (I always miss something, spill something ..) nor for drilling (I will be making soon a cnc to drill my pcb's but until then ..) and the money it cost to get pcb made is just not worth the time & effort. Or I'll just make on one stripboard ... anyhow I'm sure I will not be etching and drilling them

:D trust me, money is not an issue, seeed's 10 board deal is waaaaaaaay cheaper then my time, I do electronics for fun. I might redesign the board to be smd and order it from seeed (so that it's smaller, faster to assemble ..) but .. I definitely won't be doing anything until I finish with the soldering iron driver. I assume pcb's will arrive in next week or two so that I can start testing... I have some weird issues in simulator attm (simulator show RA4 to be open drain but looking at datashit 18F2550 is not open drain but regular output) so I really need finished boards before I can test the project and output the finished & tested layout + firmware

If I decide to go with itead/seeed you can have one board for sure :D but I'll go that road only if stripboard version don't work

BrentBXR wrote:so I usually just protoboard these days


90% of my projects I make on stripboards .. mostly on ones with circles only but sometime the ones with stripes too. They are super cheap, check out seeed: http://www.seeedstudio.com/depot/protot ... 5_188.html and they get the job done for anything trough hole.

Man SEEEDs great and all; but for protoboard you cannot beat ebay. They have EVERYTHING. (even PCB services; i have not compared prices though).

Poop! Oh well :)

FYI; I just learned when I squeeze my dog he squiks like a toy... hes sitting on my lap atm
