extremely small single led light
Description
this design takes 3 lr44 watch batteries and an led to make an extremely small flashlight it's only 10mm by 14mm. be sure to wrap the batteries in shrink wrap or some other thin insulation. kapon tape should do the trick in a pinch. this isn't really designed to be a flashlight. it's really more about making a modular light source I can put into many designs.
