Flasher
I need a circuit that will flash a light at fairly accurate regular timed intervals.
Perhaps the easiest might be a battery circuit with LEDs, but flashing a mains-powered light would be OK if easier.
It is for use as a light metronome, so I need to be able to vary it to between 40 and 200 flashes per minute.
Have searched the net: lots of flashing circuits, but none that can be varied in tempo in a reasonably accurate way.
Grateful for any thoughts!

Not flashing, but free; there's an online metronome.
Of course, you could always try the flashing metronome projects on this website...

You're quite right - I should have searched harder. Thanks!
