Scorpius Wireless revolutionary braid disc decoder for SSD

Question: 

After fitting the IR LED into the Scalextric guide blade assembly in the above experiment, was the guide blade capable of rotation?

I only ask because it looks like the 3mm hole goes through both the moving part of the guide assembly as well as the triangular chassis attachment point? if so the LED would act as a locking pin... right?

Maybe I am missing something?

Yup it’s pinned straight.

Lol nah. 
7005 s#!t itself because.... well because it’s a 7005. Was only bench tested on straight track section. Motor most likely the blame. New motor though.

Chip was playing up the moment I put on track. Intermittent.

LED Install proof of concept only.  Loop has no bends or XLCs.

Good to see Hornby use Scorpius spec diodes and fets.

The loop was fun to build. I get to use my carpentry skills and of course all the Makita tools.

Ill be installing a C7042 SF sensor into the loop soon a long with Scorpius and Carrera lap count hardware. I can add a magnet for Oxigen and eventually SCX.

So I’ll be able to test any new chip develop with up to 5 systems at will quickly and efficiently, saving time and speeding any related project up.

I have 8515 decoders ready to use also.

Revised state of the art nano board design and innovation plus.

Will it be possible.....?

Enjoy.

Similar to a jigsaw puzzle. Sort of.

So the process begins.

By drawing it multiple times in different views you really get a feel for the project. Here’s the latest side view incorporating all the recent small but numerous changes.

As you can see we only have 1.1mm of height space to work with. And a huge chunk of board missing right down the middle.

Hi Guys

Ive been forced to put LED on the bottom of the PCB due to the fact a hole in the PCB  for the LED to shine through would take up space at a critical place where we need physical strength in the PCB but also where a number of crucial tracks need to go.

So let’s draw it to get a better understanding of how this could work.

Here we have a 1.8 wide LED right behind a 1.8 mm wide blade in a 2.7 mm slot.

First pic in typical middle position.

Second pic shows guide hard against rail. 
You can see no contact between LED and rail.

All images including braid are drawn exactly to scale. Braids and all dimensions measured using digital vernier calipers to nearest 0.05mm and drawn as such. Non crucial elements may not be drawn to scale.

 Hi  Guys,

The disk decoder was first developed and shown by Scorpius Wireless. Ideas conceived of years ago are now possible with better robots, better tolerances, lower fault rates etc Example the F1 chip we announced in 2011 and the disk decoder now in progress are possible due to Nordic releasing their 3.2x3mm nRF52832 wafer chip. Better manufacturing has seen more robust and smaller components possible. 

However I think its right that hobbyists show the art of the possible when inspired by the others, follow (if it makes sense) their limited experiences..Ability to complete ideas to a useable stage are extremely rare.

Seems easy these days to take existing and/or cutting edge technology. by other manufacturers, make a variation and call it innovative.

So the project continues with 0.05mm tolerances require to get the job done. 
Considerations today: defining the exact length of the slot on the decoder. Working out wether the decoder can actually be fitted and removed in real life. Experimentation with another LED. Sourcing parts. Antenna considerations. R1 track piece CAD drawings to prove clearance. The realisation that adding the LED, and the resultant shorter guide slot is paramount and that every 0.1 of space use efficiency was required to keep the dream alive.

 A bit of a scare it couldn’t be done, a brick wall, eventually a solution, followed by a well earned Bourbon. :)

Designing a new product from scratch but trying to make one fit to so many criteria, and micro at that, is multiple times harder. Nothing has been easy on this project, as enjoyable as it is. In fact this is probably the most challenging yet rewarding projects for me ever since 2006.

Its very rare a blue sky idea actually comes to fruition. Could this actually work jn real life without drama? Lets see......

Day 24

Ah John the master kills it again and proves yet again he is at the top of his game.

Still work to go.

LED might go on top .

Accelerometer might squeeze in too.

Other work to do.

Time sheet thus far 48 man hours fur both John and I or 24 hours each.

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?

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.

Hi Guys,

Unloaded boards arrive for testing of the physical aspect,   fitment to guide, braid fitting and power continuity.
