I am just a beginner fooling around with the little knowledge I have and I made this:

Comes with schematic too Smile

Beep bepp beep, just what I needed to bring things back up to outer space after some nice classical music Wink Thanks!
However, the outputs of those of those inverters connected directly together worry me, try connecting them through 10k resistors or diodes. When one of them goes high, if the other is low that's like a short circuit to ground. I mean they certainly have output impedance but it still seems like a bad idea to me to connect two outputs directly together.
Love the simplicity though, I can't get enough of nice, simple circuits. I'll give something like this a go too Smile

Thanks for the tips. When I was inviting this I knew a very little about electronics actually (not that I am genius now, but I understand why is that wrong)... Maybe you have other ideas for version two? This schematic is completely open-source and open for improvements Smile

I'd just add more oscillators with touch contacts Laughing you have two more schmitt triggers on that chip which are unused.
