hey,

ive tried searching for this but results are very limited and explain almost nothing relevant...

what i want to do is make a shift warning beep on my mini... the same as you get from an impreza sti... sounds kinda like an alarm clock beep.

how exactly would i go about making one? would it be better to buy one? how does it come on at certain rpm?

obviously it would be wired in a similar way to a shift light... but i dont know how they work...

any info would be great...

Cheers

Chris

You'd need some sort of pulse counting device hooked up to the ignition, shouldn't be hard using some sort of PIC.

Google, Picaxe or Arduino

How about buying a cheap shift light off ebay, then wiring a cheap buzzer into the light output of that?

As above, use a shift light and change the output. But I don't know if the output would drive a buzzer.

If not, could it provide signal to a relay to drive a buzzer?

If it wouldnt power the buzzer you could use the light and just before you connect to the light use a simple contactor and run the buzzer dirrectly off the battery witha inline fuse, that might work but im not 100% positive.
