Developing an IR Remote and Software Controller

Posted May 11, 2016 by Chris

"This one is an interesting one, it’s something we’ve been looking at for a while and figuring out how to solve it. We have sets of speakers and projectors and the users keep losing the remotes, or misplaced/stolen. Usually this wouldn’t be a problem, we’ll just contact the supplier or manufacturer and order replacements. Except we can’t any more."

PWM Dimmer for LED Lighting

Posted May 4, 2016 by Chris

"I have recently moved to a new apartment and was looking for a PWM dimmer to control some 12V LED strips. I thought that should be easy enough nowadays but it proved more difficult than I thought. All I found either didn’t meet my requirements, were uggly or expensive. So I decided to build my own, tailor-made to my needs."

RGB LED Ceiling Display

Posted April 1, 2016 by Chris

"When I was measuring out the dimensions of my current home in September 2012, I realized that the main room was 20′ by 32′ and that this would make a nice Tetris playing field if the ceiling were made out of 2′ by 2′ light up tiles. I figured I could use opaque suspended ceiling tiles with a single RGB LED pointing down on to each one. With that thought planted in my head, all I needed was the time to design the electronics and build it."
