Project Keyboard

Mechanical keyboard found on the internet often come with a lot of drawbacks. I needed a compact keyboard that had all the keys I needed and at the same time it had the flexibility of programable keyboards.
What you need for this project is:

• 57 mechanical keys
• 57 Generic 1N4148 Diodes
• at least 3 LED Diodes (I used an LED strip instead)
• at least 3 330 ohm resistors
• some shielded signal wire
• a Teensyduino (you need at least 20 Digital I/O pins)
• Leaded Solder
• Soldering iron
• Hot glue (I know! the taboo word of 3D printing, but I want my keyboard to be sturdy and not wiggle as I type)
