Step 5Charging Your Battery - Part 1B
The next photo shows the front of the completed and soldered circuit.
The red lines at the bottom show how the copper tracks are aligned on the other side of the board. The blue lines show how the circuit completes through its electrical common points ( i.e. the tracks ). See how the small silver band at the top of the diode is toward the positive terminal of the battery. It allows flow towards the battery but not from it.
It is of course possible to do away with the brown wire and connect the black/negative wire the same track as the negative end of the battery. We simply wanted to show a more 'closed' circuit form.
