I've always enjoyed the honeycomb mirror arrangement of NASA's James Webb Space Telescope (JWST). To commemorate the telescope's launch on December 22, 2021, I created a set of DIY Nanoleaf LED wall panels inspired by the telescope's primary mirror.
The LED Display is composed of 18 3D-printed hexagonal cells, with 18 3mm acrylic light diffusers glued to the top. Microcontroller is a Wemos D1 Mini running WLED. Each cell has 12 LEDs, divided into two LEDs per side (216 LEDs total). 216 x ~60mA x 5V = ~64.8W peak total power draw. Total display size is ~26" long.
| Quantity | Item | Notes |
|---|---|---|
| 2 | WS2812B Addressable RGB LED Strip, 30 pixels/m | These strips draw around 60mA per LED, so size your power supply accordingly |
| 1 | Wemos D1 Mini | |
| 2-3 | JST 3-Pin Connectors, 20pk | May not be necessary, if you want to make permanent connections instead |
| 2-3 | Roll(s) of Black PETG | I chose to use PETG for the structural properties. PLA would probably still work fine. |
| 3 | 3pk White Acrylic Diffuser (3mm) | NOTE: You will need access to a laser cutter (or some other machinery) to cut these acrylic sheets. I have seen some projects that use a thin layer of white PLA as a diffuser instead of acrylic, your mileage may vary. |
| 1 | Spool of solder | |
| 1 | Soldering Iron | |
| 3 | Rolls of assorted red, black, and green wire | |
| 1 | 5V 15A Power Supply | If you choose to use more/less LEDs in your setup, you can adjust the power supply wattage as necessary. |
| 2-3 | Bottle(s) of your superglue of choice | |
| 2-3 | Screws for wall-mounting |
My Wemos D1 Mini is running WLED. I have 18 virtual LEDs set up, with 12 LEDs grouped to each.
