The long explanation... Skip this if you are easily bored!
I'm a teacher who decided to go teach in another country. Hey why not? Paid Holiday. Hell yes!
I arrived at my new job to find out I'm now teaching 2 year eleven electronics classes. Only one problem.... I have never taught electronics before. I've never even studied electronics before! So I have been on a very steep learning curve. Don't worry I know manage to work out which part of a component is positive and which is negative 50% of the time. So I think I'm basically an expert now. I just have a few problems. One half my students know more about electronics than I do and two they still don't have much of a clue either.
Please help. It's for the children!
Short explanation...
I need help designing a scorer. Like you would use to keep score of a snooker game electronically. I was trying to use a 4510 bcd counter and 4511 decoder with a 7seg counter. It works fine when I model it in the school's prehistoric version of crocodile clips but when I build it. It doesn't work unless I create an astable circuit to create pulses for the clock input.
Has anyone got a schematic for a scorer? There are heaps of schematics for electronic dices out there but none for scorers.
