Super-bright DIY flashlight
A super-bright little DIY flashlight. Today I will demonstrate how to assemble a compact flashlight, slightly larger than a matchbox and weighing only 34 grams. The flashlight is assembled on the basis of a container for AA batteries, with a built-in switch, which prevents accidental activation. Inside we see a super-bright diode with a heatsink, a TP4056 charge controller, a 400 mAh Li-ion battery and a sixty-degree lens. Several holes in the housing provide better cooling of the diode. The flashlight is equipped with a neodymium magnet for attaching to metal surfaces and a charge indicator. The flashlight is charged by charging your smartphone. So, the advantages: ease of manufacture, compact size, light weight, bright light and convenient charging. No deficiencies found!
