Donation (unused components, dev kits, working laptop, etc)

Hi all!

Not a member - still considering it. However I do have a large amount of stuff to donate. I’d like to do so this Tuesday during the open night, but I’d like to make sure there is someone there to hand it off to (I did try using the donate form several days ago on the web page, but have received no response).

Much of this is from my workplace (formerly we did some hardware, but now just software). A few other odds and ends too - no junk (I have plenty of that too - but won’t trouble you with that :smile:). List includes:

  • Large number of UNUSED (mostly sorted into separate bags if not actually organised) components, including:
  • Resisters of various values (both through hole and SMT).
  • Capacitors of various values (both through hole and SMT).
  • Logic chips (4000, 74LS families and others, both through hole and SMT).
  • Microcontrollers of various sorts (including Atmel ATMega128s, PIC 16F86s and no doubt more, both through hole and SMT).
  • Various development kits (primarily Atmel, but also a Rabbit micro controller kit too).
  • LEDs of various types (through hole).
  • A few other component types.
  • Part drawers (some of the above are in them).
  • Working Toshiba Satellite, with I THINK a Pentium core, currently running Debian (mostly boots but reports disk errors). I had been using this to drive a small CNC machine as it includes a parallel port, so this could be of significant use to the space,
  • Security camera + related gear. I believe this works, but even if not the optics look quite nice.
  • Canon Pixma MP800R multi-function printer with WiFi. Quite a nice printer actually, but developed an issue turning on (power button started acting only intermittently then not at all). May be repairable but even if not likely to have a LOT of nice bits for recovery.
  • Display board + enclosure for LED scrolling sign. Remainder of electronics lost - could be reverse engineered to drive from modern micro controller or parts (LED matrixes) recovered.
  • Some old Bunnings home automation kit, including PC interface - probably of no direct use but enclosures may be of use if building your own automation gear from scratch.
  • Probably the odd other bit I’ve forgotten.

Hi Linus,

Thank you for letting us know about these items you have. I’m sure we can find some good use for them.

will you be coming along this Tuesday night?

Yes, I was intending too. Just didn’t want to dump it all in the boneyard given I’m not a member. Will probably arrive around 6pm.

hey Linus and others…!

I was looking through all the cool stuff you donated… and I saw a bunch of new-in-packaging Atmel atmega103 cpus and also a reasonable number of atmega128 cpus ( more than 50, probably across both sorts) , and although these cpu’s are no longer manufactured, and past end-of-live for manufacture, they are still atmel chips kinda like an arduino, so they should be fairly possible to program with the modern Arduino IDE.s, etcs, once we figure out the magic incantation/s.
I was looking at one of the atmega103’s to start with ( there are more of these) , and I found that they have 128k of flash, so they are similar to a larger “Arduino Mega 1280” in programming space, but they only run at 4-6Mhz, which is 1/4 the speed of an arduino, so they aren’t quite so powerful there. ( the atmega128’s can in theory do 16Mhz and are otherwise pin-compatible with the 103’s, just being a slightly newer/less-old version of the same thing )… kinda…

Anyway, I was able to hack a “core” for the atmega103 / atmega128 by taking a zip file from here: for the “crumbuino”, and integrating that into version 1.0.3 of the Arduino IDE, and I can compile code against it… but I can’t “upload” or “program” the resulting .hex file to the 103 chip at all, as I can’t get my avrdude to recognise that there is a device attached.

So my question to everyone is… between us, can we get these cpu’s working…?

They’d be great for a bunch of things around the hackerspace, like inside RFID systems, security, or whatever, and if members could get value out of them, there’s sure to be enough that interested people could have at least a few each of them… ?

To other members, these’s cpu’s, etc are currently in the laser-cutter room till its sorted properly, please feel free to take 1, but only if you are really going to have a go at getting code onto it, and reporting back here on how you went. …

( it has some links to two neat OSX tools: “AVRFuses”, and “CrossPack” ( avrdude for OSX, which works well with AVRFuses, but also importantly claims support for the m103 chip when u run it on the command line ) :
