Basic 'clap ON' switch.

Hello,

I came across this basic clap-switch circuit demo on YouTube:


In theory, it does pretty much what I need. The idea is that when I turn on the over-sink bathroom lights, a 12V LED driver powers the clap circuit. When I clap, instead of switching a bulb, it would trigger a relay that feeds a 5V supply to a DAB radio.

I don’t need an “off” function, as the whole setup would lose power when I leave the bathroom and switch the lights off.

It’s obviously a bit frivolous, but it does solve the problem of the radio coming on in the middle of the night when I turn the lights on.

My question is: am I kidding myself trying to build this from the YouTube example?

I’ve already noticed that the SCR (Y1112) doesn’t seem especially easy to source, and I suspect the sensitivity control may not be particularly effective either.

I can machine simple PCBs myself and I’m happy to buy decent components and experiment a bit, but I’m very much a beginner with electronics, which is why this example appealed to me.

I know there are plenty of ready-made clap-switch modules available cheaply, but most seem to overcomplicate things with extra functions I don’t need.

Any advice would be appreciated.

Wal.
