inspired by J. Naudin “gege” Inductor have tried some variations of harnessing of this HF EM induction, developed by transistor’s oscillation circuit in an Induction Cooktop; it appears that the Induction Cooker is a…
The Parallax brand LCD display is easy to use with the Arduino. It only needs a single data pin on the Arduino, and 5 V and ground connections. You need the Parallax LCD library…
Here’s a small and easy inductance meter made from the Arduino and some other parts. Old TVs are a great source for capacitors, diodes, and even some chips: I found this handy dual lowvoltage…
Steorn, the Dublin, Ireland based free energy company, has announced their latest overunity technology that they have named  HephaHeat. The technology produces excess energy in the form of heat, by utilizing a low frequency…
just a test to use an induction-cooker’s oscillation circuit as a flat-coils air-cored transformer for something other than lighting…
Here I use the example sketch called “arrays” and blended it with the “potentiometer” example from the basic Arduino library with some simple modifications to serve as a potentiometer LED sweeper, which can also…
I made a couple of circuit boards, including a “color organ shield”, and found an ideal enclosure for the Color Organ. The project is now a stand-alone FFT Color Organ that works from ambient…
The Arduino is a flexible platform for controlling all kinds of devices from all kinds of input signals. Here I demonstrate the most basic Analog Input — a voltage from a potentiometer — and…
I found a wonderful implementation of the Fast Fourier Transform that runs in Arduino code, and since it uses the ATmel’s native ADC commands it can work very fast, actually in realtime, to decompose…
Here’s another SNOT update. This time I’ve cobbled together an Arduino data collection system. The Arduino monitors the gate signal from the SNOT controller circuit by the use of the pulseIn() function on pin…
