Now the DS200 is good as it gets the timing done via laps etc.. but to make the event more exciting and a clear narrative of what is happening would be the option of DISPLAY TIMING ON THE ONGOING STAGE.
Like the real timing on the WRC when the stage is being run the competitors time is shown as he drives the stage. So my question is, Is there a way of displaying the overall stage time when it is being run?

If I can get some way  to display the timing as they are actually happening the whole drama of rallying   Would enhance the event

But I've not got the foggiest idea how to assemble it and program it to do what I want. I know I could trawl the 'net and, most probably, find instructions to do something broadly similar to what I'm after............

The plan is a base plate glued or screwed to the under side of a half straight , with a box on the side for all the electronics . An overhead gantry will house the IR emitter along with 16 addressable RGB LEDS. I'll be going along the well trodden route on an Arduino Uno for the PC connection along with a relay box to turn power on and off to the circuit. This is largely unnecessary, but i like techy things and the relay boxs aren't expensive. Ill be sticking with the sport controller 3.5mm jack plugs as there small and readily available.

The main parts will be 3d printed for now. But i do run a CNC machine shop so may be from aluminium eventually. Picture below is first model files that are currently on the printer. They will no doubt get a complete re-design as i compact the electric down and hopefully make them a bit more visually appealing

What I want to know is can I remove one set of sensors from the gantry and position them 'across' the track horizontally so the counter only ever counts the one car?

I have a competition / club rally track, so only ever need to count one car. I don't mind if I have to bundle up the second set of sensors and store them in a project box.

Please help me as I don't want to find the items I'm looking at go out of stock.

I tried using Edit/laps to alter it, but I couldn't get the figure set correctly. Tried taking -4000 sections off, but it didn't work as expected.

The Wrong Race Record Score still shows on that race screen.

In the end I went for the nuclear option and deleted all the results from last night by deleting from the Stats, however that didn't work, I still have the wrong Record showing on the race screen.

Is there any way I can delete this record or will I have to delete the class from the race set up and substitute an 'new' class and start again with the records?

Hope that makes sense.

Do you fancy a true navigational slot rally, one where the driver drives – and a co-driver navigates a complex route through dozens of junctions?

Thanks to a moment of genius from Jason, we have come up with a framework that might just do the job. Okay, it's a bit of a departure from traditional slot rally, but if you want to replicate your own classic Coupe des Alpes or Tulpenrallye, a modern-day 12-Car club event, Targa or a bonkers Welsh all-nighter, then this might be for you. There’s one core navigational element required – and then it’s in the hands of the route-planner and their imagination...

The slot car technology is off-the-shelf – indeed, you might have the kit already. By its nature, navigational slot rallying is most suited to a group of friends, a club or dedicated event – with the focus on navigation, puzzle-solving and a fun social occasion. Having said that, I’m sure a SlotNav event is possible via Zoom – and Autotest-style formats with signs rather than navigation would be a fabulous single-person offshoot. Please remember, this outline is just a start – I'd love to see what people can create with the building blocks described below...

What’s different about a navigational rally?

Until 60 years ago, the majority of rallies were navigational events on public roads, usually with some car-handling ‘tests’ thrown in – and perhaps a timed special stage on private land. For a crew to be successful, the navigator (or co-driver) was as important as the car and the driver. Today, most rallying is based on exciting flat-out special stages with pace notes. The co-driver prepares and reads those notes, but it’s more akin to a driver-aid than navigation. In 1:32 scale, slot rally is all about the special stage, the car and the driver – an exciting replica of modern rallying.

Traditional navigational rallies still happen and are very popular, especially at the grass-roots of motorsport. In the UK, these are usually referred to collectively as ‘road rallies’ – but that label covers a wide variety of events and formats. In a modern navigational road rally, the navigator is the most important member of the crew. Although toned-down in terms of horsepower and speed, road rallying today is a more complex navigational challenge than ever. Think of it as a mix of driving fast down country lanes and solving mind-bending cryptic puzzles on the move... then furiously plotting the course on an Ordinance Survey map with a 2B pencil, all while trying not to annoy the local residents too much.

1.2.jpg Size: 113.17 KB Downloads: 224

Driving home from a 12-Car rally event in Hampshire earlier this month, I wondered how a modern road rally could be simulated on a 1:32 scale slot car track. The big problem is: to navigate, you need junctions... and traditional slot rally stages don’t have those. I happened to mention this to Jason and asked if he’d ever come across navigation used in slot rallying. He said he hadn’t… but a few days later came up with element I’d been missing: digital. And he created a track plan (of course!) which might help…

1.3.jpg Size: 55.85 KB Downloads: 267

This design was a brilliant starting point for the navigational rally framework that I’ll develop below – a framework that means any type of event that uses navigation can be re-created in 1:32 scale.

This is what I’ll be looking at in this thread:
