I lost my flashlight. I've given up looking for it, and I should have just bought a new one. I tried really hard to convince myself to buy a new one, but i just couldn't bring myself to spend $60-$100 for a flashlight. I tried to resist the urge to make one, but I just couldn't bring myself to spend as much money as it would take to get a flashlight that I like so I ended up making one. 37 components and 1014 lines of code to turn an LED on and off. I should have just bought a flashlight. Here's the first revision of the PCB and a 3d printed case. Next will be a CNC machined aluminum case.

It's got a Cree LED behined a cool reflector optic, and a 328P for a brain. I can plug it into my computer via USB and flash firmware exactly like an Arduino Uno, and I can even see diagnostic data on the serial console!
