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…
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…
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”…
Analysis of inductive current pulse dynamics in water electrolyses cell Authors:Â Martins Vanags, Janis Kleperis, Gunars Bajars, Andrejs Lusis Abstract We used inductive discharge voltage pulses to power the electrolysis cell with water and very…
Very interesting behaviour of the wireless power transmission system is demonstrated. This unit is the S/N 001 unit which will be the first one released into the “wild”, if it survives testing and tuning….
Q1 and Q2 oscillations in the Rosemary Ainslie NERD claimed overunity circuit. They have nothing whatever to do with function generator operation, other than depending on it as a power supply. Erratum: Of course…
Here, finally, is Part 5. I’ve added a Q1 mosfet and I’ve placed a DC milliammeter at the Battery Negative pole and a DC Voltmeter monitoring the Red FG output lead which is connected…
The bias current from the Elenco regulated power supply is used to set up the oscillations in Tar Baby and the waveforms strongly suggest that a negative mean power product would be obtained, as…
CAUTION: Flickering lights: if you are prone to seizures or are affected adversely by strobes or flicker please don’t watch this video or build this project. I can’t be responsible for any adverse… or…
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…
