I made a telemetry unit to go on board of a large model rocket that I built! The unit itself was built on a teensy board which uses the arduino IDE and language but was a little more powerful. The data was recorded on the rocket and then sent to my MacBook real time so I could see the data while ... view more

A Tesla coil generates a high frequency high voltage inside of the main coil and that ionize the air at the end of the copper wire and the air will glow due to the created arcs. Depending on the tesla coil power, the arcs could ger bigger. This project is very cool to look at but not just that. I... view more

How are these induction heaters work? We will look over the circuit and explain step by step how the oscillating signal is created, how current is induced and how the metal will get hot. Finally we use that schematic and mount a homemade version and see if it works to heat up some metals. So let'... view more
