Where I work we use large MOSFET adjustable DC load controllers to test or drain power supplies and batteries. I'm wondering if anyone knows of a DIY small version that would be useful for testing/conditioning battery packs, providing a fixed load for PS testing/development, etc?
I'm hoping for something with a feedback-based load circuit that will maintain the same current load until the V/A can no longer support it. Something on the order of 10 amps max would be most handy. Anyone already invent this particular wheel?
Hanging strings of lightbulbs off the side of the bench just isn't cutting it anymore.

Do some Google searching for Arachnid Labs (UK). They once sold a DC electronic load PCB, with no chassis, called ReLOAD. Maybe it will do what you want.
If you don't mind Chinese low price, low lifetime gear: search for KL283 on eBay. 30 amps with enormous loud fans. Be sure to read the fine print and buy one whose AC mains voltage and plug dimensions, match your country and your lab gear.
