4700uF 6.3V Electrolytic capacitor
We haven't seen many other 4700µF 6.3V Electrolytic capacitors this electrically large this physically small!
12mm diameter x 21mm long (1/2" diameter x 0.835").
The Panasonic 1381x voltage trigger detects preset voltage levels depending on the flavor you select. These are the heart of many solar engine circuits.
Standard 1N914 Silicon Diode for general purpose circuit design.
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.
1.75mm 0.5kg spool of thermochromic PLA changing from blue to natural/off white as temperatures rise and fall.
These 16MHz crystal oscillators are actually through-hole, but formed with a spacer to be surface-mount, and can be converted back to through-hole.
It's a Survival Bracelet... for geeks. Armoured full protects the wire.
SparkFun's minimal design approach to Arduino. This is a 3.3V Arduino running the 8MHz bootloader (select 'Arduino Duemilanove w/ 328' within the Arduino software).
40 Tooth 8mm Bore Pinion Pulley.
Synapse SNAP modules are super-useful, and here's a bundle to get a PC base-station up and running!
