Step 4Building the circuit
1. Build the rectifier according to the schema in step 1 (think of polarity of diodes and capacitors :-)).
2. Solder leds in parallel for tail light (this can be a little boring)
3. Solder wires from the rectifier to the pads on the power LED's PCB
4. Check the polarities and connections once more (a multimeter can be helpful)
When everything seems to be ok, then You can connect the circuit to the dynamo and spin the wheel gently. The diodes should flash immediately. When not, then check the connections once more...
Warning: when You disconnect the power LED from capacitors in rectifier then ALWAYS discharge the capacitors before connecting it again. The load in capacitors can destroy the expensive diode.
