Hacked Evolv with lithium 02
Hacked a Craftsman Evolv cordless screwdriver to run on lithium-ion batteries and have a USB charger.
The screwdriver opened up - see the new batteries and charger in the handle.
Orginal batteries where AA sized nicads with tabs. 3 of them for 3.6V, around 800mah I figure. Swapped out for two 14500 lithium-ion batteries at around 800mah each, but 3.7V. Have the LiON batteries in parallel so the same voltage, but twice the mAH capacity. Most important, put in a mini USB charging circuit. If Craftsman did this from the beginning I think it would be more awesome.
Warning: My day job is selling tools at Sears, so yeah I like the Craftsman tools.
