The Power Base Project

I wanted a semi-professional power setup at home that was universal to all type of tracks. I bought two power transformers (one for each lane) that gives 3-15 Volt regulated stabilized DC with up to 3A.	Each transformer feeds the gray box I built, also one for each lane. Out on the back of the box there is two banana sockets that feeds the track. Depending on how they are connected (polarized) you can choose the driving direction.
On this picture the Power Base system is connected to my Scalextric track. I used the Scalextric power extending cables, cut it in middle and mounted the banana plugs on it. The system is built to easily be adopted to any track.	On the front of the gray box there is three sockets for the controllers, this is also the banana standard. We use the same system and colors at the club so it is easy to use the same controllers at home or at the club.
	<== I also made external variable brake boxes that is attached on the brake wire from the handle. They use 100 Ohms variable resistors. That is a little to much. The rule of thumbs seams to be that the brake should use the same ohmage as the controller and I never have more than 70 Ohms. A 50 Ohm variable brake is probably the best. I got these resistors at a surplus shop so I might change them in the future, but they work fairly good since the knob turns 3/4 of a circle which gives rather good adjustability and controllability.
