Aussies lead the world in digital slots.

Recommended Posts

I mean just take a look at this. A digital chip half the size of your pinky fingernail. 
And wireless .......plus goodies.
 

New Nano chip in left. Typical slot car decoder, this one in particular Scorpius.

The new Nano chip is around 1/7th of the average sized car chip. That’s a reduction of around 85%

Go Aussie !

Hi Clive,

    I’ve been wanting to make an F1 chip from the start. So long in fact I forgot about it. Then seeing your very small project reminded me to pull my finger out. So for that I have to thank you.

So I rang John to have a quick chat after which I sent him a specification. The mission was to make the smallest chip for the buck. It had to be wireless with the latest technology, best quality parts and made in an ISO approved  robotic manufacturing plant. The smaller you go the higher the costs and risks as you can appreciate. It just happen to come out at 9.4x5.0

Im hoping John can start work on the firmware next week. He is busy on other projects. He has however used our purpose built programming jig to successfully do the initial program so now all future firmware updates can be wireless. On our chip all the firmware has to done from ground up. Working with the latest products is a lot of fun but it means John has to be up to speed with the latest and greatest which means learning.

We will use RF Connect app to reflash the F1 decoder wirelessly initially before transferring over to the app I’m building which already has a complete DFU (Device Firmware Upgrade ....via Bluetooth) program in place ready to go. Tested on other projects and very robust. Once your slot car can talk to your phone it opens up a lot of exciting possibilities.
And yes those shiny solder pads are gold nickel immersion for superior conductivity yet strong. And red is well, just a bit different from normal green.

Hi Guys.

   Today the worlds smallest digital decoder (As of 5th Feb 2021) breathed life for the first time. It works first time....amazing!

 

So this chip has now been programmed and testing begins. From now on we can use the app to wirelessly upgrade the development firmware. 

On a big day John may produce up to 6 firmware versions to test so this tool will be handy. Receive file on phone. Insert it into the app and press go. Its that easy.

 

Micro soldering practice today also. Lots of fun.

 

So next we will add lane changing protocols.

 

Video by John is rough, but Ill get some more video soon.

Nice work Rick and team, good to see you are still improving the product and with the top manufacturers bringing out F1 cars it’s a no brainer.

New Scorpius F1 chip fitted into a Thunderslot Lola.

Third picture shows new versus old. 
It’s amazing how fast technology moves.

Wow your recent work is fabulous. Such a great improvement in size. Leaves others well behind if size is an issue. Digital tracks here all home types but SlotNZ did build one of those automatic ones a few back but sold to local member when he went to Spain. Think it is still in Napier.  Have tried digital a couple of times in NZ and Aussie but would love to try your sometime. Keep up the good work. As a 60year slottie probably too died in wool for analogue but I have frequently kept up with your progress. Regards Chas Le Breton (charlesx)

Yeah probably all the more reason to stick with 3A mosfets so you don’t get tempted to run big currents through a board with tiny tracks and other vulnerable low current components. 

After tests we may find it beneficial to actually step up in size if reliability becomes an issue. A 12x7 decoder, time will tell and it will still be micro.


The motors used in digital typically have 2A useage on take off and settles down to 0.3 to 0.5A almost immediately.

One amazing test session using the vertical loop test track seen the Scorpius chip out survive a NSR 46K Shark at 18V after 3 x 10,000 lap test sessions.

The motor got that hot it melted the motor mounts and the motor fried. The Scorpius chip was installed into another car and it ran perfectly. So we know how not to over design a chip as well as design it.
Successful digital is very much more to scale speeds. Anything more than a 25K motor will bring slower lap times as it’s unsuitable rev range is exposed. For home tracks 18K motors are perfect. Want more grunt just up the voltage. Not the motor. Also passing through any lane changers at high speed despite the car so testing to unrealistic speeds we find is a waste of resources as we have so many projects we want to get to.

Good news. John is 99% finished on the firmware for this, he has been working on several other contracts hence the delay, but I’ll be getting some working samples late next week. Then onto the loop where the plan to try to destroy it. 
 

Below the recent video I posted showing testing going on on the loop at 8.8m/s

Thanks for the compliment Chas.

Size is important for obvious reasons, F1 cars, old classics, even motor bikes among others.

But anyone knowing how the floating motor pid should work would realise blutacking a car decoder affects handling.

The photo below shows the current generation Scorpius chip on the right attached to the floating motor pod. Attached wires add resistance due to inflexibility even we use smallish wire gauges. A guy looking for extra tenths is not going to want the motor pod interfered with.

And on the left the worlds smallest functioning car decoder attached to the chassis rather than the motor pod.

So the size matters for more than 1 reason .

And a blast from the past the first Scorpius prototype the size of a house. And an aerial as long as a fire hose.

On the menu we have also added ability to boot and reconfigure car decoder from controller from Nordic or Scorpius app.

Hi Guys,

Here’s a little video showing data streaming into the PC from the car. Just like 1:1 race cars Scorpius has telemetry. Yes the car receives throttle data and sends telemetry 100 times per second. 
In this telemetry is all sorts of goodies. It tells you what your car ID is, throttle data from 0-255 (256 steps) and similarly with brakes 0-255. It tells you what sector you are in, which lane you are in and wether the car is trying to perform a lane change. 
Telemetry is fed into the Scorpius Race Management System and algorithms work out fuel usage,  simulated tank weight, simulated tyre and brake wear with the new simulations recently added.


New telemetry to be added to the big brother Multi Protocol Decoder includes G forces, (using an onboard accelerometer), RPM (tacho using hall sensor on motor) and BEMF (back EMF detection).

These are all world firsts by Scorpius. It’s interesting that only the Scorpius system has any form of telemetry after all these years.
