5% accuracy 1/4 watt resistors to get you started with your BEAM experiments.
TR3904 NPN small signal transistor, as used in most basic solarengine designs.
This NPN transistor is similar to the TR3904, but can deliver higher maximum current at better efficiency ratings.
TR3906 PNP small signal transistor, as used in most basic solarengine designs.
The Panasonic 1381x voltage trigger detects preset voltage levels depending on the flavour you select. These are the heart of many solarengine circuits.
IR emitter and receiver in one package for close-range optical detection (sold individually)
Look, it's another voltage regulator! Look at it go! Vroom, vroom! (They go vroom, right?)
A 3.3V voltage regulator! AMAZING!
A small, but very mighty power supply. This board was designed to be as small and inconspicuous as possible.
It's a nice quad-AA battery holder, with 6" leads.
