In this video, I’m showing you a custom DIY Bluetooth Morse Coder I built. The secret ingredient is the Waveshare 0.85-inch ScreenKey, an awesome mechanical keycap that already has a sharp IPS display built right inside it!

As soon as you power it on, it instantly starts broadcasting "Morse_Keyer" via BLE. Once it pairs with your phone or laptop (look for the little blue dot in the top right corner!), it works as a universal wireless keyboard. It’s simple, but so much fun to play with!

HARDWARE SPECS:
• Display & Switch: Waveshare 0.85-inch ScreenKey (128×128 IPS display + MX Switch)
• Brain: Waveshare ESP32-C5 WiFi6/BLE5 Kit (RISC-V architecture)
• Battery: Onboard Li-Po charging circuit via USB-C (True wireless portability!)
• Case: Custom 3D-Printed 2-piece enclosure designed by me
