    Question LED Battery Status (assembled)

    Hi all,

    looking to make a battery status toy that will show you how you car battery is doing.

    Initial ideas are a 5 LED display (or a numeric read out - more expensive), that would come on for a set amount of time after a push button was pressed.

    This is still in design stages and just thought they might be useful to you lot??

    Initial estimations are cheap,and the range i can provide is varied to suit your individual needs ie - backlit switches, colours, sizes, always on, 5 LED, 3 LED, Numeric etc

    Any interest out there??

    Nick

    no checked maplin 1st - basically im looking at something you can stick to your dash, or fix somewhere, and have either a on - site (in the box) push switch, or a off site (wait for it.... Out the box) that can be mounted elsewhere.

    Red -> Red -> Yellow -> Green -> Green LED's

    Numeric ones areexpenise - i would estimate 30 complete
    LED - 10 - 15

    Who's in?

    Hey i know the chainstore formerly known as Tandys used to sell all sorts of electronics books that used to have all these weird and wonderful circuits to build - I'm sure there's a circuit diagram out there somewhere to buy or just download
