CyLight90 is a Cylinder Light consisting of 90 LEDs. The goal was to create a simple light, that could be assembled fast using cheap materials, so that you can have many of them. I use them mainly in an orchestrated way using DMX over E1.31 (sACN) in combination with QLC+.
90 LEDs is a good practical upper limit since the power is taken from internal transformer, so any USB charger/powerbank can be used, given that not all LEDs are bright white at the same time.
For safety the current can be limited to 1A in settings.
Bill of Materials
- 1.5m WS2812b strip (60 LEDs/m)
- Wemos D1 mini
- round cardboard shipping tube + caps (6cm diameter)
- 3 male dupont wires
- micro USB power cable
- solder the female header onto the Wemos D1 mini
I chose to put them under it, so it also shields the transformer, which may get quite hot
- cut, strip and solder the three dupont wires onto the LED strip
- mark about 9cm height of the tube
- cut it
- glue a half toilet paper roll onto the cardboard tube to slightly increase the diameter. this will help shift the LEDs so that “rows” are aligned more even.
- mark a good angle for the LED strip, so that it can be curled around the tube in a nice way
- glue the strip around the tube using the adhesive strip on its back
- cut a slit for the cables
- and put them inside
- connect 5V, GND and D4 as data and put the Wemos inside.
- close the tube using two caps
- flash firmware, configure
