New Components for sale:
Very bright white LEDs
Long paddle switches
10000uf 16V capacitors
N38 disc magnets
A No-Friction Bicycle Dynamo
Warning: The magnets in this kit are every strong, please handle with care.
Tools. (You also need some super-glue and bath-room sealant)
(As this picture shown) Some parts of this DIY kit package are little different from already made product (SPL).
11 is a ball magnet.
12 are 2 block magnets on bike's wheel.
4 is a already made 5000 turns coil.
13 are 2 white front LEDs.
14 are 3 back red LEDs.
15 is a 1N4248 diode (protect the white LEDs).
Now, start!
1. Scrape paint at two ends of the coil (4) by using sand paper. Be very careful do not break the thin copper wire.
2.
3. Cut the foam tape (19) by scissors, as this picture.
4. Stick 3 foam tapes onto middle of the coil.
5. Other view.
7. bottom view.
8. Push the coil into part (1).
9.
10. The coil is pushed to the end.
11. Fix cable (16) on part (1) by using the small foam tape.
12. Solder the 2 ends of the coil and the wires (16) together.
13.
14.
15. Place the rubber disc (40) at bottom of the coil.
Place magnet (11) inside the coil.
16.
17. Stick the foam tape (20) on the cover (2) as this picture.
18. Fix the cover on part (1) by 3 small (stainless steel-not attracted by magnet) screws (How to find out the 3 screws? Us a magnet). Also add a drop of super-glue at arrow pointed place to fix the wire.
19. Fix 3 red LEDs on part (5) and solder them.
20. 2 white LEDs (13) and part (6).
21. Before fix the white LEDs, add little "bathroom silicon sealant" on legs of the LEDs (as picture). The sealant will make the front light waterproof.
22. Fix the white LEDs on part (6) and solder the cable (16) and the LEDs and diode together (according to the Circuit).
23. Connect all wires together according to the "circuit" above.
24. Finished.
Now a No-friction bicycle dynamo is ready!
