This is how to make a trimet.
The parts you need are: 3 Capacitors, a 2N3904, a 2N3906, a resistor(1k to 10k ohm), a solar cell (minimum 3 volts), a dc motor(the flatter the better).
you'll also need a blinking/flashing LED (FLED).
to help you, i have made a, very easy to follow, schematic of the circuit, which can be found on http://fc09.deviantart.net/fs71/f/2010/052/a/f/FLED_circuit_by_kattejuice.jpg
teet3 made it!
