Zoomieleven driver

I made this driver to fit in a tiny zoomable keychain flashlight I found at Lowe’s Home Improvement. The flashlight comes with a cheap LED on a PCB, and no driver. It uses 4 button cells to power the LED directly. There is a clicky switch in the tail of the flashlight. It’s the smallest zoomable I’ve ever seen, and probably the smallest flashlight I’ve ever seen with a clicky switch. Since there is no driver, with a single PCB containing only the LED, I decided to make this driver board with all the driver components on one side and the LED pads on the other side so that it would be a drop-in solution. This driver is made to be small, but still have direct-drive level power output to the LED. OSH Park requires a 15mil distance to the dimensional outline to be free of copper so I padded the board by that much around the edge. If you sand down to the edge of the copper pour, this board will be 11mm diameter. That is the diameter I need for the flashlight that I have in mind for this board. This driver uses the 10 pin Atmel Tiny13a MMU chip and a LFPAK33 FET. The LED footprint is made for any CREE XP or similar LED.
