Ugh all of the research and time working I haven't been able to do any mechanical work on this thing I hope ASIC AI comes a little further do to its simplicity and less of an instruction set. And an added bonus is the power consumption.
Conundrum have you done anything with your PI Zeros. it would be interesting to hear about after all this time.

Still trying. I did look into the Movidius mPCIe cards (intended for industrial use) but they may or may not work on laptop. It has to be at least a quad core with 8GB RAM (doable), running Ubuntu >16.04 for the special inference software and API to run. Depending on the CPU used, ideally it needs to be low power but in principle an AMD Phenom 2 notebook chip *might* work underclocked though it would be a bodge. There are SBCs optimized for this system but they are mighty expensive.

Yea that whole platform is too expensive as of now. I almost want to buy a cheap mining ASIC from Ebay and experiment with using it for AI. Honesty it is for crunching numbers right? Well here it is

You will find that a normal mining asic is useless for anything other than bruteforcing SHA256, which is what it is designed for. The asic mentioned in the article is a special one like the Movidius that just happens to be designed by a company that originally specialised in mining asics.

Actually its not completely useless. I have a possible application for this. Turns out the codes used on something else are structurally similar and a powerful graphics card can translate them into an SHA256 problem sort of like a co-processor then write out a "rainbow table" that allows the standalone unit to run in some modes (eg iris recognition) using pre-coded pattern written earlier where accuracy only has to be relative as its for a prop not serious security. Thats what the PIN pad is for
Its as others have said a bit like using a sledgehammer to crack a nut but if you have lemons then you have to make lemonade.
EDIT: Useful tip. If you have a really broken graphics card get a £10 IR thermometer and run the card for a few seconds with minimal heatsink just on the GPU. If you do it right then you may be able to find a "hot spot" or sometimes "cold spot where the bad RAM is, change that chip and all should be well. This assumes that the problem is indeed bad RAM and not just crappy solder ballache on the core or bad interconnects. Also works incidentally on PS3's with similar problems.
Dead PS3s can be a good source for some hard-to-find parts FWIW.
