Hello everyone. I did not know what section to post this in. Hope it’s ok here. Or perhaps a mod can move it for me
I’m looking to make a spirit box for a friends birthday. It’s mostly a gag gift. But I still know he’ll love it. The part I need help with is making a momentary switch that constantly turns on (pulses) and I’d like to be able to adjust the frequency it pulses at too. I’ll be using a 3v radio but if I need a secondary power cct for the switch (5V?) that’s fine. It would be nice I’d the frequency could range from 1 ish to 60 or more hrtz
It’s been years since I played with electronics and I was thinking of using 555 timer ect, but got lost in my own head.
Could anybody help out with a schematic for me please? Hope this isn’t to much to ask for.
