Dangerous component/part tester December 11, 2011, 01:57:10 am check this out:http://www.youtube.com/watch?v=8UgL53mt ... re=relatedits 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:http://www.youtube.com/watch?v=ux5gh4jGS3QThat would be sweet DP product Last Edit: January 01, 1970, 01:00:00 am by Guest
Re: Whats next for dangerous prototypes Reply #1 – December 11, 2011, 03:16:17 am Dogsbody:QuoteI'd also prefer keeping a SPI connection, since its 50-100X faster than serialI´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?

Re: Whats next for dangerous prototypes Reply #3 – December 11, 2011, 05:21:43 pm 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. Last Edit: January 01, 1970, 01:00:00 am by Guest
Re: Whats next for dangerous prototypes Reply #4 – December 11, 2011, 07:17:11 pm This component tester is a great project ... do you know the home page of that avr based one ? Last Edit: January 01, 1970, 01:00:00 am by Guest
Re: Whats next for dangerous prototypes Reply #5 – December 11, 2011, 07:44:07 pm Great, thanks, I also found: http://www.mikrocontroller.net/articles ... stortesternot sure if they are identical .. checking them out - very interesting .. was thinking of making something like this for a long time ..

Re: Whats next for dangerous prototypes Reply #7 – December 11, 2011, 08:46:01 pm 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" :) Last Edit: January 01, 1970, 01:00:00 am by Guest
Re: Whats next for dangerous prototypes Reply #8 – December 12, 2011, 01:33:36 am [quote author="arhi"] I think I'm making this "asap" :)[/quote]:) Me too. Will do it on protoboard to save PCB fabrication time. Last Edit: January 01, 1970, 01:00:00 am by Guest
Re: Whats next for dangerous prototypes Reply #9 – December 12, 2011, 02:22:04 am 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.) Last Edit: December 12, 2011, 02:45:25 am by BrentBXR
Re: Whats next for dangerous prototypes Reply #10 – December 12, 2011, 02:38:08 am 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" Last Edit: January 01, 1970, 01:00:00 am by Guest
Re: Whats next for dangerous prototypes Reply #11 – December 12, 2011, 02:47:49 am 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) Last Edit: January 01, 1970, 01:00:00 am by Guest

Re: Whats next for dangerous prototypes Reply #13 – December 12, 2011, 03:19:25 am [quote author="BrentBXR"]can you make me one too?[/quote]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[quote author="BrentBXR"] I will compensate you for time and material.[/quote]: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 + firmwareIf 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[quote author="BrentBXR"]so I usually just protoboard these days [/quote]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. Last Edit: January 01, 1970, 01:00:00 am by Guest
Re: Whats next for dangerous prototypes Reply #14 – December 12, 2011, 03:28:39 am 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 Last Edit: January 01, 1970, 01:00:00 am by Guest
