Réalisation - Chemical battery
Etape 1
Report the two forms below (download from the blueprints/plan section) on the cardboard and cut them with a pair of scissors.
With an awl, make small holes in the shoes.
With the eyelet pliers, cut the holes at the back of the shoes and fix in an eyelet (the eyelet is not absolutely necessary).
Etape 6
Unscrew the battery cover of the watch. Remove the battery and replace it with the nut-washer mounting.
Screw the battery cover back checking that the two contacts (nut and wahser) are not touching each other.
The mounting must be adapted for each type battery! Check it the watch still works by connecting the ends of two wires to the battery which has just been removed. Never throw the battery in the bin. If you cannot reuse it in another device, bring it to a recycling centre.
Etape 7
Fix the watch stand on the board with double sided foam tape.
Strip on the entire length the 2 electrical copper wires and fold them in three.
Strip the end of the two wires connected to the watch. Wrap one of the them around a copper wire and the other one around a piece of galvanized metal (zinc).
