Step 1: What You Need
An Espruino Board (http://www.espruino.com)
A switch, and two wires for it
A string of 12 WS2811 RGB LED Lights
(Not shown) Wrapping paper, tape, and double-sided tape
Step 2: Cutting the Tube
Also cut another ring from the middle of the can, around 3cm wide. Cut across it as well - this will help to hold the LED lights in place.
Step 3: Drilling Holes
Put the two ends of the can back together, and tape them together on the inside.
Finally apply double-sided sticky tape around the outside of the can, and then use some patterned paper (like wrapping paper) to cover up the pringles text.
Step 4: Adding the LEDs
Then push each one of the 12 LEDs into their holes (in order). You can use blu-tack or double-sided tape to hold them in place.
Put the third ring of the Pringles can inside the LEDs to hold them in place - add some tape to it to help hold it in position.
Step 5: Soldering Up
Solder the wires to Espruino. For the connections, see Here:
Connect the other end to 'A1' on Espruino (any data pin would do for this)
Connect one end of the switch to a pad marked 3.3V (it should be right next to A1)
On the lights, take the end that was marked '5V, DI, GND', and separate out the 3 sets of wires that correspond to each marking.
Connect '5V' to 'VBAT' on Espruino
Connect 'GND' to 'GND' on Espruino
Connect 'DI' to 'B5' on Espruino (for this one, you need a pin that is marked SPI#_MOSI)
You're done - you can now connect the battery!
Step 6: Fitting Together
Make sure the USB connector faces outwards so that you can connect to it with your PC.
Step 7: Software!
Just copy and paste the code from one of the two files into the terminal window - or copy it from the bottom of the website here
You've now got a working Digital Dice! Type 'save()' and everything will be saved to flash, so the next time you power on your Digital Dice it'll auto-load the Digital Dice software!
