A handful of photos and comments regarding some of my unfinished, abandoned, failed or likewise hilariously stupid experiments, for which I have gathered up the courage to put them on-line 🙂
Neon glow lamp electromagnetic radiation indicator/detector (on YouTube too)
A small stabilized inverter was tuned right below the striking voltage of a glow lamp.
This made it sensitive to static electricity, light variations, RF fields and radiation.
An extinguishing resistor was used so that the glow lamp did not continue to glow.
(The glow lamp is located right on top)
This was a hand driven “record player”, which I made out of toys as a fourteen year old.
A plastic tube from fizzy vitamins was used as a tonearm, with a sewing needle on the end
positioned vertically, with a microphone near, all stuffed with tinfoil to help it “resonate”.
(Of course it was a record wrecker)
