How to Produce a Slot Car Video
Geting the Camera Inside the Car
With the car stripped (ohhhhhh) I could see how much space I had to play with. (PICTURE A) The car has small
LEDs working as headlights as well as a removable interior. I knew I had to lose the interior
but I did want to retain the lights if possible. The cars are easy to take apart as they are
built to be tinkered with. The silver bar in front of the motor is a magnet which can be moved
to different positions to change the handling of the car.

The first thing was to position was the 9 volt battery. This is slightly wider than the cars
chassis but because the car doors curve outwards it will actually fit inside the shell. There is
no room for a battery clip but as I wanted the battery is permanently installed in the car I was
going to solder wires directly to it. Once the car was completed I didn't want it to be opened
up again. The battery is a rechargeable NiMH so it actually only provides 8.4 volts. The tiny
camera will work with this voltage. The battery is nicely placed near the centre of the car and
low to the ground so the car remains nicely balanced. (PICTURE B)

I needed a way to recharge the battery in the car so I added a small DC power socket. (PICTURE C) This I put
in the floor of the car. I cut a small hole which the socket fits into and sits flush with the
base of the car. It is held in place with a drop of superglue. (PICTURE D)
