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…
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…
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”…
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…
Grr. The YT compression has masked the screen graticle markers. See what happens when I leave the lights on? Sorry about that….. Here I show the oscillations first at the usual low resolution to…
Here I show the “supernova mode” (SNM) and how it is different from the normal broadcast power, inverse-square falloff with distance that is expected from a broadcast system. In SNM, the power linking the…
Here’s a little Ultrasonic Ranger using the Parallax brand Ping ultrasonic transducer pair and the Parallax LCD display. Both are easy to use with the Arduino system. Just don’t try to supply more than…
The APMC (Arduino Pulsed Motor Controller) v1.0 is a very useful tool designed for helping the experimenter who want to explore the Delayed Lenz Effect or the Magnetic Lag Effect and want to test…
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…
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…
