Okay, we've got our 1.3" round TFT prototype ready for testing - and here's a cute GIF of a dial turning back and forth. It's a great way to test the display, backlight, and SD card interface. We're using a QT Py ESP32 since we need quite a bit of oomph to decode GIFs and display them in real-time. With EYESPI, no wiring is required! This is good to go - it's time to book the PCB panel!

We got some 5V USB-cable fan samples, and we're testing them out. These are handy when you need air cooling or to add motion to lightweight robotics. They come in various sizes, from petite 4cm to bountiful 9cm, and have two mesh screens to keep wires and fingers from getting caught in the blades.

WLED-compatible board. We're doing the audio-reactive test with the built-in I2S microphone this time. This digital mic will give great audio quality without needing any extra work. If you want an external mic wired far away, there are GPIOs exposed that you can solder to for another I2S connection - ESP32 lets you use any pins, which is nice! this demo is a graphical equalizer that makes verification easy! All we have left is to test the IR remote and fuse, and we're good to go!
