Tutorial - LATCH CIRCUIT
This is a simple latch circuit. Press the button once and it will turn on the output. Press the button again, and it will turn off the output. Instead of a push button, you can use a vibration sensor for example, and turn on your devices with the latch each time you sense a vibration. See belo... view more

Tutorial - TESLA COIL CONFIGURATIONS
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
