Toolduino is a simple software tool that lets you easily interact with Arduino hardware. With this software you can easily can test the circuits you create. The Arduino must be running the Firmata firmware that comes with the Arduino IDE. Things can’t get much easier for all kinds of hacks. You can just connect some →
Troubleshooting grounding problems can be difficult at best. Especially on complex automation/instrumentation systems. Use your power system drawing or a system map to document as you go because these problems can be quite complex requiring some logic to figure out. The typical utility DC bus consists of a battery charger, a string of batteries, a →
The DJ mixer crossfader was originally developed as a control for implementing smooth fades from one program source to another, but where did the idea come from? Evolution of the DJ Crossfader article tells the history and development of crossfader in DJ mixers. →
