PIC18 four-channel DMX relay controller

Thursday, October 26th, 2017

Glen Akins has a nice build log on his four channel DMX-controlled relay, that is available on GitHub:  Halloween was right around the corner and I needed a timer with a bunch of relays to trigger some store-bought props and a fog machine periodically. (Mental note: read fog machine specs carefully—not all...

DMX lighting sequence player

Tuesday, July 2nd, 2013

Paul over at Dorkbotpdx has written an article about his DMX lighting sequence player: Portland CORE effigy at Burning Man will be using DMX controlled lighting this year.  At least that's the plan, but a low-cost and low-power way to automatically play the lighting sequence (without a PC) is needed. ...

Light sequencing and decoding DMX with Arduino

Wednesday, November 2nd, 2011

Akiba of Freaklabs and the Tokyo Hackerspace has written an excellent tutorial on using the Arduino to decode the DMX protocol, a standard protocol for stage lighting displays. It includes a three-part video presentation (Part I, above) and a link to the source code. As Akiba notes, these techniques could...
