Step 15:
Feed the cable that is connected to the negative pole of the left solar
cell through under the windings to the positive pole of the right solar
cell. Solder to the cable that is already soldered on to it, and the piece
of the winding (coil) that ends on this side. (see circuit diagram)
Note:
Strip the ends of the copper wire carefully with sandpaper!
Feed the cable that is connected to the negative pole of the right solar
cell through under the windings to the positive pole of the left solar
cell. Solder to the cable that is already soldered on to it, and the piece
of the coil that ends on this side.
Step 16:
Cut off an approx. 20-30mm piece of copper wire and
tie the coil together on both sides as shown. Twist the
wire ends together and shorten with a side cutter.
Step 14:
Now wind the coil with copper wire
(10) onto the spool carrier according
to the calculator to the right. Leave
approx. 80 – 100 mm overhanging at
both ends. Once the coil is wound,
strip the ends of the coil carefully
with sandpaper.

Note:
Make sure, that whilst winding the
coil no windings get stuck at the
corners of the spool carrier.

Step 17:
General:
To ensure smooth running align the rotor. To balance the rotor
insert it in the frame. If the rotor turns away to one side, a
balancing weight has to be added to the opposite side. For this
insert the brass nails into the spool carrier drill holes. Depen-
ding on weight it might be necessary to add weights to both
spool carriers. Shorten nails accordingly.
