AVR, robotics and homebuilt control
This section preserves the electronics behind the early workshop projects: microcontrollers, motor drivers, hand-made programmers, RS232 tools, encoders, sensors, and the practical circuits that made the robots move.
Project links
Where original project pages are still available, the links below point to the preserved RoboRepRap archive.
AVR Basic Interrupts
Foundational timing control, interrupts, and logic for early DIY robotics.
Motor Drivers
H-bridges, PWM speed control, and practical drive electronics for moving machines.
LED Flashers
Classic first steps in code, timing, output pins, and visible logic.
Linear Actuators
Repurposing common hardware into controlled movement for robotics projects.
EPIA PC Integration
Embedding low-power computer systems inside larger robot builds.
Encoders
Building and reading wheel or shaft position using simple clever disc designs.
Tracking Camera
Early tracking experiments and motion-sensing ideas before modern vision libraries made it easy.
LEGO Robotic Arm
A hybrid of LEGO mechanics and servo-controlled experimentation.
Programmers
Serial, parallel, and tone-based approaches to programming AVR chips.
RS232 TX Unit
Simple serial communication hardware for debugging and machine control.
PCB Making
The board-making workflow that supported many of the electronics projects.
