This tutorial will show you how to make a battery from 3 different types of copper wire, copper wire with a small gauge and copper wire with a large gauge. These batteries can be used for electric cars, solar car batteries, flashlights and small electronics like printers/pens/clocks.
Before you begin, make sure you have 1 and 2 x 1″ long strips of copper wire with a small gauge. Cut this at right around 1/8″ wide and 2 inches long and secure each one to the PCB using the holes you just cut. They are made out of aluminum and the solder is already done when you start so it’s quite fast.
Here is a diagram to help with the copper wire.
Cut a strip of metal and about 1/8″ in diameter. The strip should be around 1.5″ wide and about 2 inches long.
Place the strip on the PCB in the hole you just cut, secure it and solder it to the holes you just cut and the hole you just punched.
Next put the metal sheet over the hole you just punched, and solder it to it. This is a trick we learned from building a small wind tunnel called the Sky Wind Tunnel.
Next place more solder on the copper wire and secure it to the PCB. This is one of the hardest things you will want to do as if you go to leave solder residue on the pads on the PCB it will corrode the copper. If you use a very high temperature solder you can melt the holes and leave a black, burnt area on the pads. I used a few drops of flux and a paper towel to wipe it off. Now just repeat step 4 to make sure if your metal is completely dry.
Now we will need to cut the battery, the wire and the battery case using the drill. Use a jigsaw or a straight punch to cut and solder all four parts together before you cut the battery.
Cut the copper wire into pieces about 1/8″ wide and about 2 inches long. This is one of the only pieces of copper wire you will need as it is not needed for cars and computers.
There will always be enough copper wire to make it through a 2.54″ long hole.
Use the hole you drilled earlier to punch one end of a piece of copper into the ground and secure it, a good location for this will be a big enough hole. If you have a lot of copper you may need to take
