Subject: [alt-beam] diode
Hello List,
Sometime I saw a description of a solarpowered robot, with a microprocessor
(PIC is guess), on the web. The solarcell charged a huge capacitor via a
diode (so that the capacitor wouldn't discharge itself through the
colarcell when there isn't enough light anymore). The same diode I found in
a solar-battery-charged (which I disassembled to check how they did it) and
had a threshold-voltage of something like 0.2 V (that's why it's do ideal
for this application). The problem is: I forgot the type-number of the
diode .... 1N58.. or so ... I really don't remember.
Maybe anybody knows the URL of the page I've seen, or knows which diode I
mean ... please tell.
Wouter Brok.
