Customizable Random Number Generator

“In this project, we will be building a “Customizable Random Number Generator,” in which you can set the minimum and maximum values. We will be using two buttons to toggle the settings on the OLED display. For example, if the …

DehneEVSE - Open source EV charging station

“I designed and built my own EVSE EV Charging station from scratch because I wanted 2 stations with each 22kW support (3 phase, 400V, 32A) and “real-time” current & voltage measurements on all phases - in order to be able to do …

DIY Arduino Audio Modulated (misical) Tesla Coil

“A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891. It is used to produce high-voltage, low-current, high frequency alternating-current electricity. The source of the audio signal in this case is the Arduino nano …
