Fresh hacks every day
Flashlights are so 20th Century. Be it the incandescent type that popped up very early on, or LED models with came around in the 90's, there's not much excitement to the devices.

He added a custom charging circuit and a Lilon battery as well as a boost-converter … [Read more...]
