hello, issue with a carrera go set.

everything runs fine for about 5 minutes then both cars stall at the same moment. after a couple of seconds they restart, again at the same moment. race continues for a bit then they stall again, intermittently, repeatedly, in tandem.

if we stop and let the track rest for some time, the pattern starts over again. tracks and braids cleaned, connections inspected, all appears well.

any ideas?

So………how to integrate Scorpius data with a race app?

Firstly a smart device can talk to 7 devices but can only listen to one at a time when using BT. But they are good at processing wifi and BT simultaneously. 
So let’s make a converter. An MPD straight into an ESP32 (hardwired), battery powered. Stand alone, no cables. Now into a nice enclosure.
The MPD listens on channel 25 and passes it to the ESP32 using SPI. Here the MPD is able to be used as a dongle as USB is not required and we can use the data port.

After speaking to Marc at SmartRace this is definitely doable.

Obviously the app receives basic race info from the Carrera CU using their BT dongle.
But the opportunity exists to take any or all of the possible Scorpius data. So what’s available?

We have 3 sites of telemetry.
1. Controller.
2. Track.
3. Car.

1. Controller: The car reads the track beacons and  processes controller data simultaneously. In the controller we gather and use this data:
Controller ID
Controller PIN 
Lane change status yes/no?
Throttle speed 
Brake sensitivity
Driver name.

2. Track: 
Sector or LB ID number.
Lane number 
Start finish line.

Each lane changer broadcasts a message continuously from the track LED we call a beacon. The car gathers this info and uses it for various functions. 

So far we have 2 lots of important data. But about car data? 

3. Car:
Car specific telemetry.
Throttle speed after being mapped.
Firmware version number.
Tacho reading.
Hall sensor.
Accelerometer X axis.
Accelerometer Y axis.
Accelerometer Z axis.
Sound preference.

So around 16 lots of data within the telemetry stream. Some of this data is useless and others look promising.
Like having your automatically entered into the app ala Scorpius RMS. 
Collision detection between any amount of cars. From what direction. And how much for.
So now we can detect who shunted who, who caused a collision at any lane changer, detect deslots, detect roll overs. 
Tacho for tuning and testing. Even fuel usage.
More accurate throttle readings more often for working out fuel useage. Same with brakes using brake telemetry.
Of our transmission window we dedicate around 30% for telemetry so that’s around 30 transmissions per second which equates to a maximum 10 complete packages per second. This gives a true and accurate picture to pass to to the software/appware guys.

Welcome to the new era.

   

                                                       Here from the slot car museum is a 1/24th scale slot car set by Tamiya of Japan. The set has 2 trays containing the the parts ,one sitting on top of the other. The cars are Lola T70s. One is red and the other is blue. The set cars differ from the kit cars in that they are already assembled and painted by the factory. You can see the over spray in the photos of the underside of the 2 cars. The set contains enough track for a figure eight with borders and white fence. Check out more when you google bernards slot car museum. I am missing the cover top for the box which contains the fence and borders so if anyone has one I would be interested.

Hey guys,  Its getting colder outside and so my track is getting more use. I tried Smart Race for my Scalextric Arc track and am wondering how I can view my practice lap times after completing a practice session?
 I can't figure if this is available or its an Add On I would have to purchase?

Hey everyone,
I’m Emdadul Huq, new to the SlotRacer community and excited to be here! I’ve always loved seeing how people bring creativity and detail into their tracks and collections. I’m still learning about the different models and track setups, but I’m fascinated by the engineering and precision behind it all.
Looking forward to chatting with you all, picking up tips, and maybe sharing a few photos once I get my own layout going. Thanks for having me!
Cheers,
Emdadul

Hot on the heels of a successful swapmeet in Cobham, we continue to find a replacement venue for the popular Orpington Swapmeet, so we move on to Leatherhead

                       

Help please. 

Can anyone iD this slot guide, with as much info as possible, as it's absolutely IDEAL as a replacement for the Pioneer Legends guide and I'd like to get some more.

Unfortunately it was the only one in my loose slotguide stash. 

Thanks for any help with this.

Hi all long time away but I really want to ask has anybody a comparison between the rs200s with 20k motors &9/27 gearing & new models with 18k motor &8/31 ratios etc. plus the chassis differences ,how do they compare?

Digital is IDENTICAL to analogue with just 2 essential differences.
You have multiple cars per lane. 

And yes you need to read the instructions.Takes 30 minutes.

So when I race digital I have EVERY benefit of analogue plus some nice (very nice) added functionality.

My timber track is identical to analogue, with lane changers added.
And I can run it in analogue.

The cars I use are designed and built for analogue. Tyres, gearing, prep, chassis, weight, balance, COG mentality identical.
My controller is for analogue but can be used for digital too. 

Add lastly show me a 1:1 circuit anywhere in the world where every car races perfectly units own lane. Imagine if LeMans was 8 lanes wide? 
How unrealistic is it? 

And can you deal with a fellow hobbyist in your lane like real Motorsport? 

Another benefit. I can run 6 cars in 2 lanes cheaper and more space efficient than any 6 lane analogue track. So for many digital is cheaper and can actually fit in your loft. Double bonus.

Then we have the simplicity of analogue, albeit with limitations.

Me? I can run both, enjoy both and therefore comment on both.

Add no I’m not talking about digital systems from the toy market. Personally I couldn’t use them knowing what Ive experienced. 
If your first experience was with a toy market level system you may have had a bad experience. That bit I fully understand. First impressions count. My first impression was that  poor I decided something needed to be done about it. So I did.

I once had a race with 90% analogue guys who had never run digital before and at the end of the night every single racer was super impressed. No missed laps or other glitches. One guy even giving it 11/10.
So yup. First impressions count.
Make sure your first impression is on a pro setup.
