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 ...
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) ...
