Intro: LED Eye Fidget
Just like the spinning hand fidget toys that occupy you
while you think.
The LED eye fidget occupies you by providing a soothing cascade of color, light and patterns.
What you will need:
1 12 X 12 X .118 inch clear acrylic sheet
1 12 X12 X.118 inch black acrylic sheet
1 can thin acrylic cement (or other glue)
1 adafruit Trinket (or other small Arduino like processor) (https://www.adafruit.com/products/1501)
2 adafruit 8 pixel led stick. (https://www.adafruit.com/products/1426)
Step 1: Cutting and Assembly
Use your laser cutter and the Corel Draw pattern (provided) to cut out the LED fidget items.
The Items on the right of the drawing are the clear items.
Choose the clear item you want and cut out 16 of them.
The items on the left of the drawing are the black items.
Cut the black items out and assemble them using the clear cement so they resemble the photo.
Be sure to assemble the box so that the large slots are on the outside of the box.
Once the black items are assembled and the glue is dry. Glue the clear items to the front of the box.
Step 2: Inserting the Electronics
Once the enclosure is complete and the glue is completely dry.
Wire up the LED sticks and Trinket on the outside of the box. The PDF file contains the breadboard wiring diagram.
Connect the assembly to your computer and install the strandtest.ino program (provided) into the Trinket.
Test the program and be sure that the LEDs light etc.
Get some tape and with the LEDs still "on" place the LED sticks into the enclosure. Move the LEDs up and down in the enclosure and observe the brightness on the outside of the box. When you get the LEDs is the sweet spot use the tape to hold the LEDs in place.
You can use hot glue to permanently fasten the LEDs or just use tape (as I did).
Now fasten the Trinket to the bottom of the enclosure with double sided sticky tape (or hot glue) and enjoy.
