Customizable IR Blaster Case - ESP32-C3 SuperMini

Behold! A fully customizable infrared blaster powered by the ridiculously small but surprisingly capable ESP32-C Supermini. This isn't just a project; it's a testament to the fact that good things do come in tiny packages (and require a steady hand for soldering). Using the included OpenSCAD design, you can tweak its dimensions and appearance to your heart’s content, making it a truly one-of-a-kind remote control. We're not claiming it's going to take over the world, but it will let you control your TV, lights, and other IR-controlled devices with satisfying precision. 

Features:

• Tiny but Mighty: Leverages the ESP32-C Supermini – soldering skills required!
• Customizable Design: Modify dimensions with the included OpenSCAD file. You could fit it for a whole other Controller and sensor/actor.
• ESPHome Powered: Can be integrated into homeassistant.
• Compact Design: 23mm x 18mm x 27.3mm
