Argh!

Alright seriously, whats so hard about plans for building a night vision camer, IR camer, or thermal camera?! I've spent about 4 hours now looking everywhere for some schematics of any of these, but do you think that I can find any, of course not. It's starting to get me just a wee bit bloody pissed off! Well, now that I have most of that out, everything should be all good, till I decied to look some more anyway. Hope your all having a great day!
