Recreating a 2,200-year-old experiment from home, with a twist
A high-precision NTP client that syncs a small IoT device to within 1ms of UTC
A miniature version of my full-size stand, still with a slip ring to power the display
Monitor air quality trends without giving up control of your data
At a local museum, we spent the day demonstrating 3D printing, moldmaking and casting
Pyramids don't roll very well, so I made D4 dice with 8 sides. You can download and print your own!
We needed a drain stopper for a party. What's the fun in buying one when you can make it right at home?
This platform rotates 3 times per hour and brings power to the tree through a slip ring. Made from wood with 3D printed gears and motor mounts.
A tiny circuit board to help run costume lights off a portable power brick
Friends wanted a wedding cake shaped like a D20 die. We made a 3D model of half a die, printed it in PLA, created a silicone mold, baked the cake, and covered it with fondant cut with a 3D printed cutter.
My friend has a tattoo that looks like a circuit board. I made a real circuit board that looks just like it—but actually works!
3D printed cookie cutters for making a gingerbread house—including a tutorial for making your own!
A 3D printed fountain based on one I saw in a Japanese Garden in Portland. My first attempt at making something that moves water.
Rarely does building a treehouse require welding, grinding, painting, riveting, bending, crimping, plumbing, brazing, laser cutting, sound design, printed circuit board fabrication, 30,000 lines of C code, distributed network protocols, sewing and embroidery. Ours did.
We tried to modify an RC boat with a GPS and software to have it be self-driving. Many of our projects take way too long; for this one, we limited ourselves to one weekend, no matter what. It didn't work, but it was fun and we learned a lot.
I built a small test rig to test the shutter speed of the mechanical shutter on a Lomography camera.
Keeping our toaster alive was my original motiviation to learn 3D printing. As time went on, the fixes got more elaborate.
A fun, light-up ornament for the cyclists in your life. Originally inspired by a friend's tattoo!
A 16-button keypad with all the software and mounting hardware to make adding it to your Arduino project a snap.
An Arduino shield for quickly and easily adding old-style (DB15) PC joysticks to your sketches.
A circuit board that increases the battery life of your Ikea Duktig Stove to years. We also sell replacement buttons.
