“Random” Numbers Box

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.

Meteorite Giftbox

This was built as a gift to my wife for her birthday. She is a big space nerd so I found a small meteorite and purchased it as a gift. While a piece of space is cool, it wasn’t very easy to find an impressive way to display it. I eventually found a vintage film box an designed the internals to build a scifi-esque stone containment box.

The box consisted of the vintage metal box, a piece of walnut plywood, a 3d printed cone and display platform, some hand bent aluminum bars, an rgb led ring, an arduino, two vibration motors, and a 9v battery.

Using a small switch in the rear, I turned the box on before handing it to her fully gift wrapped. This started the vibration motors gently vibrating in a sinusoidal hum. The rgb leds also started gently cycling through the spectrum as it could be felt physically vibrating.

It was featured on Hackday shortly after I submitted it. She loved it and it is still displayed on a shelf in our home.
