Sphaericae has a dimension of not bigger than 20cm. The wheels are driven by an 3D printed internal gear which is driven by a sun gear. Engine power is provided by two 12V 110RPM [4.5Kg.cm] geared motors with on the back an encoder. On the...
You can program and test your boondock without an enclosure. But we recommend you 3d print the enclosure to protect the board. Open the link for details

After 4 evenings of hasty development, the 3D printed parts arrived last night and I was able to assemble a first prototype for outside the garden. Today we went to the field test site Weilburger Grenze (Gießen, Germany) to test the sensor under...
Power coupling to the leg lift shaft is created by an oldham coupler created out of an old piece of oak flooring and glow-in-the-dark 3d printed plastic. Currently testing PLA.
ok major redesign, new welded suspension and oil filled shocks, needed less boing and more vroom, 4.8mm mild steel should take the punishment from the drive modules far better than 3d printed parts
I ordered keycaps to 3d print service 2 weeks ago and I have keycaps now. Below photo is keyboard with keycaps. It seems like I have done all what I planned.
Once the SOT-23 part is attached, pop the 3d printed cap on! It is a friction fit for me. To make them permanent and to keep the legs from shearing off when you bend them, fill the rest of the cavity with resin and cure it.
The PCB and 3D files can be ordered directly on PCBWay. Ver 2.0, I increased the number of LEDs from 7x7 to 8x8, then modified the order of the pins, and increased the LED output signal.
