I'm trying to make a digital metronome for drumming as my AS Design & Technology project.
Anyone got any ideas where I could find a suitable circuit to use, or somewhere that sells metronome kits?
I'd like it to have a single flashing LED, aswel as row of LEDs to simulate the movement of a traditional metronome. Also as sound outputs I'd like a speaker (preferably one that makes a diferent tone on the 1st beat of the bar) and an output jack to headphones. A BPM monitor would be very clever but I think that is probably getting too complicated!
I've found a site selling kits that fulfil most of my requirements, but it's in the US and they wont ship to the UK.

Anyone got any ideas?
Any help would be much appreciated.
Cheers,
Ben.
PS. I've checked with teachers and no using a kit is not considered to be cheating!

Try Maplins: http://www.maplin.co.uk/
Look under Projects/Mini Kits, there is a kit there, but doesn't do everything you ask.

IWatkins - Thanks for the suggestion, I'll take a look.
stevie c - I'll just ignore you, but if I thought it'd get me an A I'd try it!
teen_machine - AS level, new word for the 1st year of A level, the exams were introduced last year. The idea being that if you drop a subject after a year you get some credit for it, i.e. half the UCAS points of an A level.
Any other ideas people?
Cheers,
Ben.

Looking at it as an intellectual excercise (that is why you are doing it, right? ), find out about astable multivibrators. You are right about the digital display, that is going to be a bit of a step. I guess the teachers are thinking of kits as a box of lego, rather than what you are going to get, which is a list of "put resistor 'a' in hole '1'" type Ikea-ready-built instructions.
Don't know where to buy kits - but all you really need are some bread boards and op-amps / transistors plus the mandatory spread of capacitors and resistors. Yours from your friendly local Maplins.
Good luck mate.
