If you’ve got a party coming up and are looking to add a little bit of excitement, you might be interested in this recent project from [Gav Lewis]. The build is based on a commercially available party light, but with some upgraded components the final product is brighter and more dynamic than it was stock.
Realistically, [Gav] has changed out almost every component of this light except for the enclosure and the front lens. The original 5 mm LED array was replaced with a new 8×8 WS2812B panel, and the electronics completely replaced with an Arduino Nano. He’s still using the light’s original power supply, but as it only puts out around 4.2 V, he’s added a boost converter to provide a stable 5 V for the new hardware. He also added a small 12 V cooling fan, which he says is basically silent since it’s only getting half its rated voltage.
[Gav] has developed a number of lighting patterns with FastLED that do a good job of emulating what you might see from a much more expensive laser scanner. In the video after the break, you can see how multiple colored beams of light exit the housing at once, projecting patterns on the opposite wall. He says he’s like to restore the device’s original sound activation mode, but as of yet hasn’t gotten the code sorted out.
This project uses a off-the-shelf 8×8 matrix of WS2812B LEDs, but if you ever find yourself needing to piece together your own array from individual LEDs, we recently covered a great tip for making it a bit easier.
