| This is a fully functional flux-gate compass made at home from scratch. A physics demonstrator that could be useful sometimes, but also a so...
| Here is a simple and inexpensive yet effective RF comb generator that, once driven with a 100 MHz signal, produces regularly spaced harmonic...
| There are many cases in which a current measurement that does not include DC is useful. The most common is the case of Current Transformers...
| Because the first musical Tesla coil the author built was not entirely satisfying, he decided to build another one following a new approach....
| This is a very simple, but effective comb generator that, once driven with a 100 MHz signal, is capable to produce regularly spaced harmonic...
| Do you need to measure the antenna current of your HF transmitter? Or, like me, the primary current of your Tesla Coil? Here are some design...
| A musical Tesla Coil with Bluetooth streaming from the smartphone! Fully digital, with sigma-delta modulation implemented on an ESP32.
