Chapter 3 — Power Hacks
With two of these, a little wiring to put them in parallel, a connector, and a Kodak Advantix
film canister (see Figure 3-13), you can create a small, simple, high-capacity battery pack.
FIGURE 3-13: Simple starting material
Here’s how you build this pack:
1. Take a Kodak Advantix film canister and make a small pinhole near the bottom on the
side; as shown in Figure 3-14.
2. Put a small amount of modeling clay into the bottom of the film canister. You will
need to experiment with the amount that you use here. This will be used to push the
batteries up against the terminals. Figure 3-15 shows a cutaway of what you are aiming
for here.
