How to avoid tearing your switch wires when reassembling an Emisar flashlight.

Emisar D4 D1 D1S Anduril is a custom firmware created by Toykeeper for certain enthusiast flashlights. It is open source, and available for download and flashing to your light, free of charge. You just need a few dollars worth of equipment, and some time to spend setting up the software. Alternatively, I also supply custom preflashed MCU's for the most popular lights. So if you are more comfortable with a soldering iron than a software kit, you can buy one designed for your light, with custom modifications even, and just solder the new chip in!
