Simple frame and stand for RGB colour-changing edge-lit display. Designed for 3 mm clear acrylic, template provided (
You will also need:
engrave your design onto 3 mm clear acrylic using the template provided. Best to keep the design ≥ 10 mm from the top and sides and ≥ 20 from the bottom edge. The template has a central cutout for a 5 mm LED. Don't forget to remove the acrylic protective paper!
(optional) glue thin strips of aluminium foil to the top and side edges of the acrylic sheet to improve brightness of the image. This is immensely fiddly, and may not be worth your time.
glue the mitre frame pieces to the top and sides of the acrylic sheet
slot the framed sheet into the top of the stand. The front of your image should be on the other side of the stand from the USB battery bank cutout. At your option, glue the sheet into the stand.
Program the Digispark with the
DigiRGB sketch, and install the RGB Shield
- Plug the Digispark into the power bank, and install it into the base. The stand was sized for the ubiquitous cheap square USB power banks - you may need to improvise if yours is different. Also, you might consider covering the base of the Digispark — I accidentally shorted one and fried its power regulator.
