Reader [Eric Mockler] brought Louis “Lebel” Wichinsky to our attention, a colorful inventor he ran into some years back in the Borscht Belt of Upstate New York. Described as a Mel Brooks doppelgänger, Lebel was born the son of a baker in Hurleyville NY. During WW2 he served in England where he lodged with two brothers who also owned a bakery. When his British friends suggested he should build a bagel machine because “you Yanks can do anything”, he accepted their challenge and began working on a design. Despite taking a detour through Israel as an aircraft mechanic on his journey home, he finally succeeded in 1964 after 20-some years of tinkering. A patent followed in 1968, despite discovering that someone else had independently invented similar device.
Chances are you’ve never wondered what your goldfish is trying to say, but if you have (or if you just want a project), check out this DIY hydrophone.
You will need a computer microphone, vegetable oil, plastic wrap, scissors, solder, and a small unused plastic bottle. Solder the mic capsule to an appropriate length of cable and test. The entire assembly can then be submerged in vegetable oil inside a plastic bottle. Yes, vegetable oil. Seal the bottle and you’re done.
