We have been told for our As-level coursework, we have to design and make a circuit and were given a few ideas. I decided to look at an electronic dice. After looking at the option I chose this electronic dice because it sounded like it could be fairly advanced. This dice is to be used in board games such as ‘monopoly’, ‘cluedo’, ‘ludo’ and ‘snakes and ladders’ It has to be easy to use and cheap to build.  

         

Research

For the research section I started looking on the Internet, using search engines and found very little of what I wanted. I used the ‘Yahoo UK and Ireland’ search engine and searched for ‘electronic dice’ and ‘electronic dice circuits’. This showed up very little of what I wanted. It can up with results for companies that sell electronic dice kits for you to build at home rather than circuit diagrams. I then searched for ‘electronic dice circuit diagrams and found…

After doing this I decided to go to the library and look in books there and from home. If searched in books including, ‘electronic options by P.Gormley, L.S.Hagan and C.C. Atkinson. This had no information on any relevant circuit diagrams but had lots to do with thyristors and relay diagrams.

        Next I searched on crocodile physics V1.7 for any relevant ideas and found what I was looking for. I found an electronic dice circuit (below) and an electronic counter from 0-9 (below). This is the basis for my circuit. I then looked in my old GCSE course notes and found 2 helpful circuits. I found an electronic dice circuit using a 4017B decade counter and a circuit for an astable 555 timer chip circuit (made below on crocodile physics.)

Specification

Dice are used in a variety of ways. Mainly for board games. For this reason the dice needs to replicate a standard 6-sided dice and it needs to count up to 6.

The system I am aiming to create has to be able to be run off a small voltage battery. (I.e. a 9v battery.) It must be easy to use and be cheap to build. It has to be, made up of ...
