Converting A 5HP and 1HP 460V three Phase Milling machine to run on single phase 220V 30A Project Insanity Hacked that VFd! 😉 Recycle… Reuse… video of moving this beast here: Blessings. ~Russ http://rwgresearch.com/
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…
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…
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 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…
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…
The phase relationship between my traces will no doubt be questioned by viewers of my previous videos. As I have explained in detail elsewhere, the phases must be accurately measured if they are 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”…
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…
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…
