You might think, "I'm worried about the durability of 3D-printed gears." Certainly, they cannot compete with metal gears. However, for robot prototypes and hacking applications, the performance is ...
On a chessboard, a pawn moves forward on its own. A knight jumps in an L-shape. A rook slides in a straight line. All 32 pieces are independent robots. Moreover, it is open-source and anyone can build ...
Compact Magnetic Encoder IC Supports Both On-Axis and Off-Axis Position Sensing for Humanoid Robots, Quadruped Robots, Servo ...
There are plenty of radios you can buy that pick up MW and SW bands if that’s what you’re into. Or, you can follow [mircemk]’s example, and whip one up yourself instead. The build employs an ESP32 as ...

When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they ...
To measure the motion of wheels by odometry, two rotary encoders of 20P P R 20 P P R (pulse-per-revolution) are coupled to each reducer shaft of the motors. To operate the motors, a dual motor driver ...
- CW mode : IQ band scope + keyer + CW auto-decode + waterfall - LSB mode : SSB transmit/receive (Si5351 phase modulation TX / Hilbert transform RX) ...
