This is a spinning top design that uses a Hemispherical Gimbal drive system that has been minimised to fit inside of a hand held toy. The hemisphere will rotate with the outer body. The angular momentum of the spinning top will drive the hemisphere....

The attached idea came to me today. I didn't see a comparable design online so I thought to get the idea out as fast as possible so it might spark further ideas. Ideally any 3d printer could be cannibalized to build one in just a couple hours....
CAN Simple nodes all look pretty much alike. Only the headers on the top change. There's a tremendous amount of connectivity available on that top row, including two UARTs, I2C, SPI, PWM ports for motor drivers or servos, a quadrature decoder, a bunch...
The clock consists of the tops arms and the bottom base. The long arm contains 2 stepper motors, The arduino and the stepper drivers. The Stepper motors although being small consist of a gearbox pulled out of big servo motors. This gives them enough...
This year I had a special gift for my girl. Earrings that feature an oled screen with animations of her favorite arcade game, Tetris. The original idea was to have tetris blocks fall from the top of the screen to the bottom and stack up. But in the End...
I started this project wishing to build the station around a pen form factor with USB PD as the power source. However, as I started using the perfboard prototype built around the USB PD idea, I realized the RT series of tips really are best used for...

Because of the box design, the side guides can't be a straight but have a step. The guide i design is to be cut on CNC router from 3/4" plywood or MDF , but can be 3D printed as well. Since the middle wall is 1/2" the guides should be either attached...

Design Description Overall, the GRIP consists of sensor inputs sent and processed by the ESP32, and then data sent to the web-server through websockets. The web-server then also pulls the 3D hand models from a github repository based on the sensor input...
A few years ago I ported a Z-Machine player to a little arduino-like device. Ever since I have been meaning to get around to a project that would work on a TV with a real keyboard and once again rekindle fond memories of long nights playing Zork on my...
