This was conceived after noticing my first son’s love of the microwave and oven’s displays. This was a project to get me back into building stuff after being out of the loop after having a baby.
This consists of an Adafruit esp8266 feather board with 4x 7 segment display and an spi accelerometer. The feather features an built in lipo charger which allowed a quickly implemented lipo battery in the build. Next I designed a case around the components and assembled it. Both of my kids loved it before it was lost under a couch and the battery died beyond revival at which point both of them were interested in bigger and better computers.
