For anyone interested…

The precision speed measurement and display is being readout using 4inch LED 7 segment displays I showed elsewhere on slotracer.online.

The high speed cars are based on brushed motors (e.g up to King Evo 50) and a two part decoder which places high power MOSFET control directly at the motor. Again, shown elsewhere on slotracer.online.

Alternatively the high speed cars may be based on SENSORED brushless motors if that workstream proves successful in the coming weeks.

Thanks for reading.

I’m going to call the configuration of digital slot car racing described in this thread ‘System-D’. The ‘D’ stands for development as the system is more of a development platform rather than being aimed as a commercial product.

Key features of this system:

1/ IR signalling for lap counting and lane changing using the Mark/Space timing method with signal inversion for lane change. This is designed for up to 36 cars.
2/ Enhanced track sensors for reading the IR signals which use 4 phototransistors in a row for increased performance on high speed tracks.
3/ Wireless communications from throttles to a central wireless hub which onward broadcasts the throttle data to the cars in a single multi-car packet refreshed every 10ms.
4/ Fast USB over-ride of packet data for advanced simulations and smart pacer cars.

Thanks for reading this overview post about the digital slot car racing configuration I am calling ‘System-D’.

I think "System D" is totally appropriate for this project.
But hasn't the whole thing been rendered obsolete by the new Carrera Hydrid system which allows for up the 30 drivers on track and anywhere lane change/overtaking?

Hi Joel, what a great question!

Perhaps the answer is that the current Carrera offering is more of a toy with some great characteristics but also a few limitations compared with digital slot cars - the latter including:

- relatively low car speeds.
- cars are battery powered.
- lack of customisation/tuning options.

However, the idea of cars being guided by electronic sensors rather than physical slots is exciting, and as you say it offers lane changing anywhere.

So looking into my crystal ball… perhaps the future of digital slot cars will retain the ‘slot’ for electrical power pick-up but allow cars to transition between slots at any point, guided by sensors until they reach the adjacent lane’s slot where they next pick up electrical power? Just a thought.

If so, System-D would be a useful development platform to start to explore this.

Meanwhile I’ll wait to see if, and how, the enthusiast digital slot car community chooses to engage with the new Carrera Hybrid system. Also, let’s see whether ‘user demand’ drives commercial activity in the ‘technical solutions’ domain for hybrid systems.

As I say, great question :)
