  1. By the way I mentioned the accelerometer idea on SFI back in 2007. Gee that only took 14 years to implement.
  2. Hi Guys, Accelerometers. Scorpius was the first company to specify an accelerometer for the digital slot car industry. We will be the first to market also The MXC6655A 3 axis accelerometer is only 2x2x1mm and is around $1.25AUD. a much better proposition than a 9 axis gyro which is overkill, 4 times the cost and OBSOLETE. For slot cars a 3 axis accelerometer will perfect. Small, cheap and from MIMSIC who lead the industry. Uses: 1: Ghost car. Here the the X axis is monitored and speed reduced as G forces increase. Calibration may be required. Early days. 2: Side impact collision detection for lane changers for use in applying penalties using the Y axis data in the Scorpius Race Management System (SRMS). 3: Front to rear collision detection for use in applying penalties using Y axis data in the SRMS. 4. Impact data collected and used in Damage Simulation for SRMS. Using an addition of all 3 axis. Once you reach a certain level of damage you must pit or retire from the race. All this will be done in car, processed by the powerful nRF52840 CKAA-R chip. And data will be fed into the processor at 100 times per second. The same data will be sent wirelessly to SRMS for use in applying penalties etc. As you can see this is very advanced for the current tech level in the industry.
  3. I must admit one component on a 5mm thick pcb with expert soldering is not only astounding it’s proof of innovation, years of hands on experience and honesty. And only 4 years into it. Quick too.
  4. Hi Guys, Once the decoder is manufactured it’s time for anything hand soldered. In this case it will be 2 LEDs, one phototransistor directly onboard and then various hardware attached to multiple wires. Heres a sneak at progress so far on a diagram. It’s only for the car decoder so far not the Lane Brain for 4 brands. Once the diagram is completed a spread sheet is compiled on the parts for each sub assembly. The idea is to keep costs down that lights and hall sensor are sold additionally. Why pay for something you’re going to cut off and put in storage? The other idea is in the web shop you will be able to customise the decoder any way you want. If you’re purely a Carrera user and SCX driver wires, SSD LED, and Scorpius photo sensor don’t interest you we can remove those. Want lights? We can add those. Want the tacho option we can include the hall sensor. Want the onboard Carrera LED or the fly lead LED? Or both? You choose. Anyway I have been working spec for the various wiring and accessory bits and pieces. Included in the spec hardware variations and associated wiring, AWG, length, conductor material, insulation material, strand dia, number of strands, strip insulation length, tinned or not tinned ends, single wires or pairs? choice of IR LEDS, clear LEDs headlights, red LEDs taillights, photo transistor, hall sensor, wired pair or single, colours, heat shrink, diameter, material type, colour, length, split cores to accomodate?, shrink or not shrink?, part numbers for each, check availability, etc. That’s for each of the sub assemblies x 15. So now to complete the drawings and then the spread sheet.
  5. Scorpius latest skill set is miniaturisation. It’s been a fun challenge, very enjoyable and satisfying. Developing state of the art designs is not cheap. It also devours time and effort. But it pays off. Now more than ever since we are developing the MPD. Here are 3 miniaturisation projects we did in recent times. Pictures below: 1. Wireless Disc Decoder project for Scalextric systems. On hold while we complete the MPD. Design complete. 2. Scorpius Wireless Nano Decoder wiyh world record dimensions of 9.4x5.0mm or 47.00 sq.mm. To give you an idea the worlds previously smallest chip ever manufactured was 325 sq.mm being the Scalextric F1 decoder. The Nano Decoder is 1/7 the size with triple the functionality. Project completed with all firmware completed and tested and programming jig manufacturered. 3. Scorpius Wireless F1 chip 12x8mm with beefed up motor and brake drive circuits. Still under 100 sq.mm and These important projects have just raised the stakes and given us a serious head start on the latest MPD. The new MPD is just 292.60 sq.mm. It has also given us new bootloading and programming experience with the newer Nordic development platforms. In our arsenal of chips specified in designs, prototypes or manufactured include so far: 24L01 51810 52811 52832 52832 WLSCP 52840 WLSCP 53 series is yet another development platform again and would require much effort to learn it.
  6. Hi Guys Some pics showing more detail. Red is side A. Blue is side B.
  7. We have used 41 of the available 73 pins on the 52840 WLSCP chip! For a slot car decoder? And as far as wire to pcb in/out pins on the new decoder we have an 26 pins all up! In fact around the perimeter there is maybe room for 1 more pin only. We have really maxed out everything. So let’s see: 2 pins Power in 2 pins Motor Drive 2 pins Aux Motor Drive 1 pin Antenna 3 pins Hall Sensor 2 pins Carrera on board LED 2 pins Carrera LED on flylead 2 pins Scalextric Sports Digital onboard LED 2 pins Scalextric Sport Digital on Flylead 2 pins Onboard Photo Sensor (Scorpius lane change) 2 pins Photo Sensor on flylead (Scorpius lane change) 2 pins Headlights 2 pins Tailights That’s around 38 solder points!
  8. Hi Guys, Ok so hardware design took 3 man days spread over the last few weeks. A lot of that was spent researching materials, replacements for parts not available due to world shortage on some important lines and availability of the entire BOM. Monday we start the production files and design a new programming jig pcb (only way to go) that will accurately guide the 3 pins exactly to their target +or -0.1mm. The jig must be robust and professionally built as it will be sent to the factory in Taiwan for use eventually on the first production run. I think I will order 20 maybe 30 of these beauties. These unfortunately will have to be programmed and wires/LEDs/PTs soldered all by hand. Next I’ll start integrating our own app rather then the Nordic app for upgrading .That should be fun. Luckily it is something we have had completed successfully in another wireless project I’m involved with. So it’s well tested and works flawlessly. Rick
  9. So how’s 22.00x13.30mm? That’s just 292.6sq.mm! How does the worlds most functional decoder (by a factor of 5 at least) also be the second smallest? The Scorpius Nano Decoder is the smallest of them all at just 47sq.mm. However it doesn’t have any fancy hardware. This decoder acts as a car decoder for 5 brands, as a lane changer decoder for 6 brands, as a lapcounter for 5 brands, (Using our own Scorpius Race Management System), as an anti collision device for 5 brands, and finally as a location detector for 5 brands. Don’t forget also it has built in full function lights. So 21 products all up in one that can change identity in 30 seconds flat using our app off the phone. And just 292.6sq.mm. Scorpius.... industry development leaders since 2007. Pictures showing both sides of the latest Scorpius MPD just 22.00x13.30mm.
  10. Bud the last post was 8 years ago.
  11. So how small can we make this decoder. Previously we had it at 26x13, then revised it and added an extra photo transistor circuit, a couple of zener diodes, a solenoid driver circuit and a few other components and got it kept it at an amazing 26x13. Just had an email from John. He may be able to get it down to 25, 24 or perhaps even 23mm in length. Or 299 sqmm So I wonder what John can achieve?
  12. .....Are you saying you need to do 4 years of Uni, consult, lecture and have a lab in Japan to make a light connection board and maybe upgrade a resistor or say cut a certain colour wire Ade?
