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…
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…
hey guys, I thought I would share this as I found it interesting. RWGresearch.com
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…
Pulse Motor Build Off 2013 Contest Update #1 check out peterhalleffect for ideas on what we are looking for. www.youtube.com/user/peterhalleffect Original video for PMBO 2013 please see this page for all details and information:…
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 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…
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…
