Want a back-lit keyboard? Make one yourself. Though you may not want to after seeing this build by [prodigydoo], who devoted 40 hours to upgrade his mechanical keyboard with a smattering of shiny.
No eye rolling just yet, though, because [prodigydoo’s] work is a monument to meticulous craftsmanship and dedication. So what if he accidentally dropped the keyboard’s PCB and cracked it? He patched that up with a few wires in true hacker-problem-solving fashion and no one will ever know.
With the electronics “safely” removed, [prodigydoo] set about desoldering every single key switch, then carefully detaching and disassembling the Cherry MX Blues. He then inserted an LED into each switch’s backplate, reassembled them, mounted the keys back on the board, then added some current-limiting resistors and heat shrink to the circuit. [prodigydoo] cut a few necessary holes for a power switch, state indicator LEDs (Caps Lock, etc.) and some under-the-board lighting, then rounded off the build by hooking up a power supply capable of running all the lights.
No microcontroller? No RGBLEDs? We like it anyway, and it seems [prodigydoo] is glad he kept it simple. Go check out the gallery for gritty details, an explanation of the circuit, and more pictures than your family vacation album.
