Have you ever wanted a display that is a little larger then one you can buy?
Have you ever wanted to make a display the way you wanted it?
This is how I made a custom multiple color display that I use for temperature.
Step 1: Supplies and Tools
Safety Glasses, Gloves, Etc. ( Be safe )
Clear casting epoxy
Black Enamel Model paint
.093 inch Acrylic sheeting
A bit of balsa wood
1- Arduino or other microcontroller
72- 470 ohm resistors
46- Surface mount red/green leds
46- Surface mount blue leds
3- 0.1uf Capacitors
Assorted size wires
5 volt power supply. I used a phone charger.
Needle nose pliers
Assorted Sand paper
Hot glue gun
Assorted other tools
Step 2: Style
This is easiest to lay out on a piece of graph paper.
You can draw a few different styles. Though there really are only two styles I know of.
Straight up and down and slightly angled.
I like the slightly angled look.
Draw it out on your graph paper and using a razor blade cut out the individual pieces.
The pieces of graph paper are then placed on a large eraser so the eraser can be cut to shape.
For the decimal placed I ripped the eraser off the back of a pencil.
Perfect circle : )
