Step 9: The battery holder
We will hook are battery holder in serie to get higher voltage but with the same current.
Four battery of 1,5Volts will give 6V of power.
If you use rechargeable battery it will be 4,8Volts
To hold your gear in place, I have use some terminal block, I have remove the plastic and cut the terminal in two using a saw. I simply put them on the shaft to hold the gear.
You can even use small tie-wrap instead of terminal block.
