introSimple electronic dice

Ever wanted to make an electronic dice? I designed a simple and small circuit, that fits into every pocket.

You might wounder why this is better than a normal die. It significantly increases your geekiness level.

The biggest part is the battery, because we're using a 9V battery.

step 1Parts

It's hard to understand, why some people build circuits with so many parts. You can build the same thing with less parts and it still works. You will be surprised by the n…


step 2Soldering it together

It is time to solder it on a board. The size of mine was 80x55 (mm). That would be about 3x2 inches. You are free to use wires on the board, so that it is easier to connect…


step 3Software

It's a no brainer that it can't work without a brain. We're using the ATTiny26 because it's small, cheap and powerful enough for the dice to work. I had some problems chan…


step 4Diffusing the LEDs

Chances are that you bought normal LEDs and now they are too strong. After looking directly at them, you get partially blind for a while. A good way to diffuse them is by …


step 5Showing it off

Ive seen this done with a much smaller chip, I think it was a PicAxe 08M, Instead of a PTM switch there was a "shake to make" switch, making it more dice like.

it's kind of hard to understand how you soldered it together.you should do a drawind on paint or something to simplify it

very nice!

i'm going to do this as my first real project.

thanks for the instructable

P.-S. :do you know where to get the materials?radioshack?

That was a great idea. But even if i thought of that, I still couldn't have made it. I only had enough leds for one and the avr would probably be too weak.
