Fresh hacks every day
Building RGB LED displays is one of the most interesting programming and engineering challenges we see here on Hackaday. Not only do the creators of large displays and LED cubes have to deal with the power requirements of driving a whole bunch of LEDs, but there’s also the issue of getting the frame rate high enough to display video. It’s … Read the rest
[Garrett Mace] decided to dress festive for New Year’s Eve. What he came up with is a fedora ringed in LEDs that react to music. The hardware uses 5050 LEDs on strips. Three of them encircle the head-gear providing a total of 114 RGB pixels. Each is a WS2811 module — a part which we’re seeing more and more … Read the rest
[Cunning_Fellow] published a post with three proof-of-concept approaches to driving a WS2811 LED pixel. We looked at a project early in December that used an AVR microcontroller to drive the RGB package. [Cunning_Fellow] saw this, and even though he doesn’t have any of these parts on hand he still spent the time hammering out ways to overcome the … Read the rest
[Alan] has been working on driving this WS2811 LED module with an AVR microcontroller. It may look like a standard six-pin RGB LED but it actually contains both an LED module and a microcontroller to drive it. This makes it a very intriguing part. It’s not entirely simple to send commands to the module as the timing must be … Read the rest
