Sonicare Head Holder

I am a big fan of the Sonicare toothbrush, but I’m not a fan of how large the heads are and how hard they are to store between uses. Since my girlfriend and I share a base, we always have a need to store the heads when we’re not brushing our teeth.

Since my bathroom is tiny, I wanted to be able to have something that would hang on the wall. I searched online, but I couldn’t find any existing products that would work. Thus, I decided to design my own hanging Sonicare head holder. This is what I came up with:


It is a laser-cut design made of white acrylic. The heads slide on, and the vents allow for any trapped moisture to escape. I used nodes on the interlocking portions to make the pieces better fit together.


If you’d like to make this yourself, check out the design files on the GitHub page. You can also buy it ready-made it on my Ponoko page.

Arduino Pong

I recreated the classic game Pong with an Arduino.


During my Arduino training sessions, I tasked my students to come up with a cool project using Arduino and various sensors and other electronics I had collected. This was my project entry.

Check out the video demo to hear the beeps!


This project takes advantage of Adafruit’s SSD1306 OLED driver library and GFX Library.
