Arduino: Software FFT Color Organ, First Steps
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…

Pulse Motors: SNOT Update 2: Arduino Data Display of Velocity and Energy
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…
Extreme High Voltage: MagLevES Motor v2.0 with Arduino Tachometer
I rebuilt the base and electrode mounts of the maglev ES motor, to match the new pencil-less armature. I am also working on an Arduino sketch for pulse motor control, and here I decided…
Arduino 16: Magnetic Levitator Optically Controlled
Here’s the latest project, an optically-controlled magnetic levitator using the Arduino. The OSEPP Uno clone runs a sketch which senses the position and velocity of the levitated object, and sends a switching signal to…
Scoposcopy: Supplement: Arduino’s Method of Inductance Measurement
To complement the earlier video on inductance measurement by resonating tank, I’ll now show a slightly different method used by the Arduino inductance meter. The Arduino uses a bit of external circuitry to “strike”…
Ofenrohr HHO Katalysatorheizung von Holger – Oventube catalysator HHO heating
www.overunity.de English description translation see below. Hier sehen wir die Katalysator Heizung von Holger, die in einem Ofenrohr eingebaut ist und in die von unten verwirbelt HHO eingespeist wird. Das HHO Gas wird dann…
Arduino 5: TKThermosensor w/ Alarm, Airflow Sensor
I used the same circuit arrangement as in the last video but with the addition of a piezo speaker element. A negative-coefficient thermistor is used along with a 1K resistor as the “potentiometer” sensor…
Arduino 1: TKTracker Simple Light Tracker
A single RC servo and a couple of cheap CdS photoresistors make the Arduino “look alive” by making a simple light tracker. With just a few lines of code you can make the arduino…
Arduino 7: Switching a Heavy Load Using MOSFET and PV Sensor
Here I continue to demonstrate the versatility of the simple Arduino pot-voltmeter system. NOTE: I get scrambled when I describe the mosfet pin hookup. The Load has no connection to the mosfet gate, it…
Arduino / Electric OU: Camera Intervalometer Data Logging System
I needed to record some time-temperature-power data over a long period of time. So I made this Arduino simple intervalometer to control the Canon camera through its external shutter release cable jack. The system…
