This is a design for a "Stream Cheap", an inexpensive DIY version of the Elgato Stream Deck. Although I made this to take the place of a Stream Deck, it's really a mini macro keyboard that can be used as a hotkey board for any program.

Build Instructions

1. Print out both parts and tap the bolt holes in the base to fit an M3 bolt.
2. Insert the switches into the faceplate and wire them up. One post of each switch needs a signal wire, and all of the other posts are connected to ground.
3. Solder everything to the Arduino. The ground connection goes to "GND" and the signal wires go to pins 2 - 9. I numbered my buttons from left to right and top to bottom, but you can wire them in any order that you like. If you have the connectors, use those rather than making direct connections.
4. Bolt on the faceplate to the body.
5. Print out the button icons and apply them to the keycaps. Firmly press the keycaps onto the button stems.
6. Upload the firmware and enjoy!
