Scorpius Wireless revolutionary quick change braid plate decoder
#31

Standard equipment on the SSD disk decoder will be 422B, a one-part, acrylic-silicone blend conformal coating by MG Chemicals, that cures to a durable, flexible and smooth finish. It is easy to apply and can be handled in only 8 minutes. It may be removed with appropriate strippers, or soldered through for repair or rework.
422B is designed for applications where both high service temperature and flexibility are required. It puts minimum stress on components during thermal cycling, making it ideal for applications that involve a wide temperature range. It provides strong protection against moisture, corrosion, fungus, dirt, dust, thermal shock, short circuits, high-voltage arcing, and static discharge.
Features: Excellent corrosion resistance, tested in salt spray environment with no oxidation or coating damage.
Yet another world first for Scorpius Wireless.

    Dummy boards have been ordered to test fit and power connections.
We are using ultra thin 0.4mm 4 layer boards never before used in the slot car industry.
Is this the most demanding and precise slot car electronic project ever undertaken?

            Next stage will be to produce prorotypes. Then test vigorously. But how?
This is the Scorpius digital multi protocol vertical test track which is currently being assembled Downunder.
It will test chip performance on motor drive performance and reliability as well as  lap counting and lane changing performance, k limits and reliability.
In the picture anti clockwise we have:
1. Carrera Control Unit.
2.Scorpius Lane Brain. This will drive the LEDs and receive lap count and lane change commands. A program we have puts a timestamp into an excel file and produces a bell tone on every successful command, so you can hear it while you multitask. Switch between lap count and lane change using a quick wireless reconfiguration.
3. Scalextric C7042 Advanced powerbase.
4. Scalextric Arc Pro powerbase.
5.Scalextric C7030 powerbase.
6.Ninco digital powerbase.
7. SCX Advance. Empty. Trying to easily source V2.0 compatible Bluetooth lapcounter.
8. Oxigen. Empty, Magnet to be installed under track for start finish line. 2 magnets to be installed for pit stops. Oxigen lane change chip to be installed for lane change testing.

This is in preparation for current and upcoming projects. 
The loop makes for efficient large scale testing, generally in runs of 1000 or 10,000   laps. 
All lane change testing will be done by routing solenoid driver wires to an LED or possibly a modified Scorpius car chip back to the rest program.
Testing of lapcounting on the various systems will use proprietary powerbase or dongle and accompanying 3rd software if chosen/applicable. 
Test loop hardware to be powered by a lab quality 20V, 30A or 15V, 30A regulated and variable power supply in order to test at various voltages/speeds. Connecting leads for each powerbase except SCX have been made up so far.
Simple banks of switches will be used to isolate each powerbase as required.
First test will be the F1 chip which arrives early next week. 
And very soon the Scalextric braid plate chip.

Hi Guys,
   Here’s the final design. Long story but we made it by a square millimetre or 2.

Next stage order unloaded boards for physical fit....

So this can be used to coat the electronics boards of a camera inside a doorstation, for instance?

Hi Guys.
     It became obvious half way through this project it is impossible to fit the newly built disc onto a standard Scalextric guide without modifying it. Thus a 3D guide must designed be built. This however takes away some of the gloss in regards to a quick fit.
Still a great idea and product. We will pick this up once work on the main project, the MPD is completed.

Yes definitely.

Update: As you know all the hard work had been done, design, firmware complete, production files complete.
But one issue. After trying every possible configuration it was impossible to make it work with a standard guide.
The whole idea of this was the quick fit. 5 seconds to convert any Scaley car to digital.
Obviously if we need to redesign the guide it defeats the purpose. 
Still weighing up if this is a viable go ahead.
At this stage I’m saying no.
And honestly it’s all over a millimetre miss.
So close yet so far.
