Goldmine Electronics had a sale on USD5096F 35 Volt, 35Amp Schottky diodes (they’re now sold out), so I bought a handful. These are the old style all metal stud mount package, and come without any mounting hardware. The stud is 1/4 x 28 threads, so I had to order some 1/4 x 28 TPI nuts

I did a search of my blog and I couldn’t find this topic, so I think that I blogged this ‘way back in my late, great watsonseblog. So I’ll go over this again. Sometimes it’s necessary to use a Zener diode for overvoltage protection. It can also be used as a shunt regulator, but nowadays

The photo is of one of my Supercharged Joule Thief circuits that I built a few years ago (see link at the end). This one has a supply current of 70 mA at 1.5V and a LED current of 25 mA at 3.3V (actually 25 millivolts measured across the 1 ohm [2 resistors] in series

I took this pic a while ago, May, 2001. The germanium chip and catwhisker are so clear and visible. The GI stands for General Instrument company, the maker. I know that silicon chips are light sensitive. If germanium chips are, then this one should make a good light detector.
