Controlling your computer by using hotkeys and macros is a great way of speeding up your workflow. Unfortunately a device dedicated to doing that (for example Elgato’s Stream Deck) will cost you about $120. That is why I designed FreeTouchDeck. FreeTouchDeck will cost you about $20 (including shipping!) to make. It uses an ESP32 and
