Step 11Modify battery holder
I really wanted to keep this project small so I opted to try a 6V, barrel shaped battery (Duracell 28A medical battery). I couldn't find a battery holder for it, so I decided to mod a AA battery holder.
Cut & Sand
With a small hand saw cut the middle out of the AA battery holder - about 1/3 from each end. Chuck the middle piece and sand down the seams of the other pieces. You will be putting these ends together. Measure and use common sense so that you don't make it too small or too big. Check often against your battery.
Epoxy
Epoxy these two pieces together. I used a spare chunk of thin plastic to help secure it. Epoxy the two halves onto the plastic base. Repeat for the 2nd battery holder.
