| Can a tiny $2 full-range speaker deliver surprisingly rich sound inside a miniature Fostex-style back-loaded horn? In this video, I build, t...
| A unique combination of astronomy, embedded programming and ambient lighting that transforms an ESP32-powered display into a realistic real-...
| Wi-Fi HaLow successfully bridges the gap between traditional Wi-Fi and LoRaWAN. In this test, an ESP32 camera streams real-time video to a H...
| These amplifiers prove that a well-designed and carefully built analog circuit can survive decades of hard use and still perform reliably.
| Boost converters replace the mains transformer here: 12 V goes in, 230 V comes out for the anode and 16 V for the heater. At maximum volume...
| Wi-Fi HaLow successfully bridges the gap between traditional Wi-Fi and LoRaWAN by combining long range, low power consumption, and enough b...
| This project demonstrates that practical object recognition does not always require complex machine learning frameworks. Using only the buil...
| In this project, I convert a classic PCL86 single-ended tube amplifier design to operate with the less common PCL82 vacuum tube. Powered ent...
