I connected color-coded wires to an RGB LED and three PWM pins on an Arduino Micro. I covered the Arduino in shrink tube and exposed the reset button. I kinked and tidied the wires before securing them in a hexagon arrangement. I compressed the sides until they touched, and I could fit the top and bottom pieces in place to assemble the device.
KeyRyptex after assembly
I tested my assembly, but ten keys were not responding correctly. I added RGB LED code and made the puzzles easier so I could "win" on the broken hardware. I made the light shows easy to recognize.
At least the lights work
I was close to abandoning KeyRyptex, but I opened it and saw a mess of broken and shorted connections. I replaced the stiff diode leads with flexible silicone-coated wire and reassembled it.
Improved wiring
I tested the buttons with a USB cable and miniature clamps to hold it together. All buttons worked and code reflected each press. I redesigned the end caps to add threaded rods instead of gluing the pieces.
Redsigned top and bottom
I cut the redesigned pieces on the laser cutter and tore open the device. I added a switch through the new bottom, and a battery with charger inside. I ordered threaded rods, but the shipment was empty so I held it together with clamps while I let the battery charge.
Packing the electronics inside
I created a schematic for the KeyRyptex, using parts from the Keyboardolier design and making some modifications to fit everything neatly on one page.
