Education

Hardware projects for learning and teaching. From simple STEM experiments to complex builds. Hardware kits, development boards, and lesson plans for classroom use.

In this project, I built a simple yet effective variable high voltage power supply using affordable components, offering precise control for high-voltage experiments.

In this project, I convert a classic PCL86 single-ended tube amplifier design to operate with the less common PCL82 vacuum tube. Powered entirely from compact DC-DC converters, this amplifier delivers maximum 2W of warm tube sound with absolutely no audible hum or switching noise.

This project demonstrates that practical object recognition does not always require complex machine learning frameworks. Using only the built-in camera, display, and processing power of the UNIHIKER K10, it is possible to create a simple, fast, and effective object recognition system that can be trained directly by the user.
