I panicked this morning when my last battery started to die on me. I pulled out the soldering gun and a few spare parts and came up with this. It actually pulls a strong cloud of juice considering it's primitive appearance and dangerous bare wires. The battery pack fits well in my shirt pocket and if I am leaning back in my chair the switch and tank don't bounce around. Strictly for computer desk\chair use.
I hope no one takes this mod as a serious design. It should only be used where fire insurance has been purchased.
