Hi Guys,
   Ever head an event where you need to equalise cars?
I’ve held a couple of events with handout cars. NSR cars in one event and SCX Nascars in another event. Motors vary in tolerances and therefore speed. This makes for an unequal event.

So fast forward to 2023. We currently have a design layout which includes Back EMF detection. This circuit detects a pulse in back the back EMF that feeds back from the motor to the decoder where the magic happens.

The MPD is not just a car decoder. It’s an advanced micro computer for slot cars if you like with its own proprietary real time operating system. 
Information is analysed. RPM is shown on the plug in plug out OLED. screen or you can use your PC (and later app) to see RPM.

Now use the configuration program on your controller or PC to limit tech, ie 21,000RPM. Upload to car and now you have all cars equal RPM.

If that isn’t enough you can handicap any car using speed limiting now settable in car not just on controller.


The great thing is all these functions are purely firmware. All with one piece of hardware, the MPD.
