A little Halloween fun. Made with an old pair of eyes and some LEDs inside in a white silicone tube. 60 SK9822s in total powered by an ESP8266 18650 module.

I used the ESP8266 version

The most useful post was trying out the teensy SPI hack to run four sets of SPI leds from four pins. I only used three sets but it worked and I’d been wanting to try it out for ages. I know there’s no great advantage with bit banging but I wanted to see if it would work.

Thanks @Chris_Parton ​​​, the eyes are early prototypes for the masks I make. Your pumpkin is very cool too :slight_smile:
