hi,
It was 25 years ago when I designed the dice, explained in my PP.
I have no documentation from that time for the dice. I will have another search thru my doc's asap.
I recall using all CMOS i/c's, 40106 i/c as the pulse gen, 3 * AA batteries located in the base of the dice.
You can buy ready made battery carriers.
It used 7 red and 7 green, minature led's, one color for each dice face,
[remember lots of games require two dice, (die)],
The shaker 'ball bearing' we had gold flashed to improve the contact with the shaker funnel.
The overall dimensions about 6cm cube, with rounded corners, made from
a hard wearing nylon based black plastic. [black gave the best led contrast]
We designed the dice as a promotional item, for our customers, we made around 100 units.
Also produced 10 units in real silver cases!! for our prestige customers.
Please post your concept circuit, like to help.
