Picture of LED dice
Recently I was deleting some files from my computer and found some photos of my old project. It was made a few years ago. It's very simple and don't require much time, skills and materials. This dice helps me to relax and come up with ideas. I hope you will like it!
P.S. You can give it as a little gift for someone with no reason.

Sorry for very poor video quality. It was captured with my old phone...

Step 1: Tools and materials

How I mentioned you will need just a few things, which you will find in your house or in dads garage. If you dont't find something, you can buy it just for a few dollars in local store:
  • 3 or 4mm drill bit;
  • drill;
  • a jigsaw
  • sanding paper;
  • 4mm plywood;
  • super glue and wood glue;
  • lighter with LED torch;
  • switch;
  • blinking two color LED;
  • soldering iron and solder;
  • clamps;
  • spray paint.
And of course ruller and pencil. No work can be created without their help

Step 2: Drawings

This dice is very simple so drawings are simple too. What you will need to draw is just six 3x3cm squares. Four of them have 2x2cm squares in the center, which will be cut out. Bottom has two openings: one is for swich and other is for battery holder.

Step 4: Sanding and painting

Assembling is easy too. first of all, take four midlle parts ant apply some glue. Then put them together, press it firmly with the clamps and hold it like this for an hours.
While body is pressed and drying, take your bottom part, insert battery holder and glue it. Don't forget to screw the switch. After this, solder LED to battery holder and switch. It's very simple.
When it's done with electronics glue the top and the bottom to the body. Leave it for a few minutes because super glue dries quickly.

When labeling the die the opposite sides should add up to seven.

So is there one side that doesn't have a lit number? I'm confused about what the "bottom" looks like at the end and how you put batteries in at the end. Is the die weighted or does it roll fairly randomly?
DOT. (author)  minderbinder10 months ago
Yes, you are totally right, one side ("bottom") isn't lit. I don't have any photo how bottom looks like at the end. But batteries holder is open from outside, so it's easy to change them. This dice was made just for fun so I don't think it will roll quite well

My english isn't very good either, so don't be afraid to ask if you don't understand something. And thanks for appreciation!

It's amazing the number of people that don't know that. I bet they've handled and looked at many dice and not noticed.

Good project. Excellent use for left-over plywood.

Good job. One quick tip, though. Opposing sides of a die should always add up to seven.
If you look at a commercially available die you will see that the side with 1 pip is opposite the side with 6 pips. The side with 2 pips is opposite the side with 5 pips. And the side with 3 pips is opposite the side with 4 pips. I.e. 1+6, 2+5, 3+4 all equal 7.
