Re: gEDA-user: Need help repairing a damaged FPGA board (GR-PCI-XC2V)
Just a bit OT but:
since you refered to students, you might like to check wether the
following evaluation kit is suitable for your needs:
AVNETs
Xilinx® Spartan®-3A Evaluation Kit
http://tinyurl.com/avnet-dev-kit
Features beside the typical FPGA stuff:
somehow open (datasheets, etc. given)
an existing forum for user discussions
an usb interface for programming (sending the bit file is not done via
ISE webpack but with a own software tool)
ISE Webpack free edition on CD
embedded PSoC chip with CapSens-Button and the necessary programmer
(miniprog) for the PSoC.
Rather much free I/Os compared to other eval-kits
power-over-usb (makes it more difficulte for fry it ;) )
and finally the price
the drawbacks as I found them
I/O-banks are fixed already to 3.3V logic.
less I/Os then a "real"-developer kit
ISE Webpack is not open source ;)
However, it cost "only" 49 dollars. Thus instead of buying (or fix) ONE
expensive regular development kit you could propably buy a set of those
and hand one to each student. Makes it a bit more redundant.
Hope that helps a bit

A relatively new professor here at OSU had one of these FPGA boards:

Unfortunately, some students recently fried part of the power
regulation circuit. We don't have the expertise to repair it
ourselves, and we don't have the budget to buy something new. This
board was being shared by multiple students, one of whom was using it
for his masters thesis work. So its loss is rather painful and
problematic.
I was wondering if anyone could advise us on repairing this. Perhaps
there is someone whom we could ask to repair it for us? Trying to get
the original manufacturer to repair it would probably cost more than
it's worth. The damage was done to at least the C12 and D9 components
(lower left in the picture).
Any suggestions and help would be most appreciated!
