Building a DIY Stream Deck (Mini Macro Keyboard)

I’ve been doing a little streaming on Twitch (hiya!), and a lot of streamers I follow have something called an Elgato Stream Deck.

Pulling the trigger fires, sliding the hammer back “fans the hammer”, and spinning the cylinder reloads. The gun also includes an inertial measurement unit (IMU) with an accelerometer and a gyroscope. This allows me to track movement for aiming. McCree’s…
