Soldered it up today and it works. Hooray!!!

Look and listen:



The circuit is the tiny black blob on the right, the speaker is wired directly to it. Please note the method I use for bass-enhancement: the speaker is put onto an empty pickles-jar (which btw is a trick I learned from the local natives. I modernized it by leaving off their complicated traditional cleaning rituals and simply used a dishwasher. Also, I left off their - at least for my taste - somehow disgusting secret tricks to boost it even more they whispered to me late at night.)

I tuck one body-contact between thumb and index finger and touch the other one or more fingers. (Finding: it is rather difficult with these small contacts to produce a high-pitched tone. The original design with a large bolt and a tin-can, which is grasped with the whole hand probably gives a better range.)

The light show is nothing but a gimmick from MM Magazine. Cool

and the schematic.

I'll see if I can make a video,. or at least record some sound.


Idea

which reminds me ... filing the top off a metal can transistor ... it will be a photo transistor then .. like them oolde bc107's ... anyway with a lens in front it could count cars passing at 30 or 40 meters or so on my multimeter .. it could save some LDR's maybe here or there ... no holes tho I guess in this particular design I took the quote from.
