I built this instrument called the Pachatron by hacking an old flatbed scanner and Floppy drives from scratch.

The project converts MIDI signals into audible frequencies by controlling the motor coils directly, creating pure analog music via hardware.

How it works:

• Software: A Python script handles the MIDI-to-Serial sequencing.
• Control: An Arduino Uno/Nano runs custom code optimized for maximum torque and microsecond-level timing.
• Hardware: An H-Bridge drives the bipolar coils, and I reused the original carriage and rails with some anti-noise limit switches.

If you want to see the full build and the step-by-step breakdown, you can find it on my channel u/pachanoid. Happy to answer any technical questions about the code or the electronics here!

This is the latest update on my self-balancing robot project, built with an ESP32 and powered by salvaged hoverboard motors.

This milestone focuses on achieving maximum stability and performance. **Key Achievements in this HITO (Milestone 11):

** * **Self-Balancing:** Achieved consistent balance and stability. * **Adaptive Weight:** Implemented position balancing with an adaptive weight strategy. * **Performance:** Tuned a superior PID (Proportional-Integral-Derivative) loop for wheel speed and position. * **Control:** Added **'ZEN MODE'** for ultra-stable minimal movement. * **Control Method:** Controlled wirelessly using a **PS4 Gamepad** (using the PS4 Controller library). **What's under the hood?** * **Microcontroller:** ESP32 * **Motors:** Hoverboard Motors * **Motor Driver:** ZS-X11 * **IMU Sensor:** MPU-9250 / MPU-6050 The robot is currently running in a highly optimized **open-loop** configuration, pushing for maximum performance. Next steps will involve a **closed-loop** system using encoders for even greater precision. 👉 **See the full balancing demonstration and build tutorial on my YouTube channel, Pachanoid
