Hi chris_bomicino and Andy P,

 

As you say Andy lots of discussion to date on this topic re 4 lane ARC PRO but not aware that anyone has done it as yet.

 

My view is that the simple doubling-up approach is unlikely to work as the ARC PRO puts the signal line low until the blade detector sensor is interupted. Its only when the blade detect sensor is interupted that the signal from the IR LED on the underside of the car is passed through to the powerbase electronics.

 

Hence there are three issues in attempting to use a lane changer sensor paralled up...

 

1/ the sensor design is different and does not incorporate a blade sensor.

2/ you would have to find a suitable signal point on the sensor board as the standard output jack is designed to power a solenoid rather than couple into a circuit as a pull-down transistor.

3/ the main blade detect signal in the ARC PRO blocks all signals anyway until it itself detects a blade, so n signals would get through if paralled up..

 

All of the above makes the challenge difficult but not impossible...

 

I, with others, am currently developing a small circuit board which will use a microcontroller to interface to all the necessary sensors for a four lane start/finish line (and up to two pit lanes). The microcontroller will then output signals correctly onto the main circuit board of the ARC PRO.

 

This is quite a complex project involving new hardware and new embedded software. Not easy!

 

I hope all of the above is helpful... and, of course, if there is any easier way to do all of this... I would love to hear from others...

Hi JPaindaveine,

 

I think this is one for Scalextric customer care... it sounds like an internal fault inside the powerbase and better to ask Scalextric to fix/replace (assuming it is under warranty ).

 

By the way, what happens in analog mode? Is the A lane ok and the B lane dead i.e. similar to digital?

 

The fact that one lane functions in digital mode suggests all four electronic output transistors on the main circuit board of the powerbase are fine - hence likely it is a detached internal wire. That said, best route would be to ask Scalextric customer care for assistance...

 

Hope this helps,

 

C

Bought the ARC Pro for my son and spent 2 weeks trying to figure out why the app wouldn't count more than 1 lap.

Fault was apparent using any car on either lane on a basic oval track using 5 different devices. All other functions of the app worked including, calibration, lane change, braking, etc.

After following all the advice on the forums and contacting Scalextric I still could not use the ARC Pro as the most basic function of lap counting is required.

I came across this Magic ARC app whilst reading the mostly negative reviews of the official Scalextric app on Google play store.

Downloaded the Magic ARC app to android phone and the ARC Pro works perfectly!

I think it's quite embarrassing that the Scalextric app is inferior to an enthusiasts app... not taking anything away from the App creator  'Cristiano Ruisi' as it better in all areas. 

 

If the official app only counts 1 lap, while the magic app counts laps correctly it is likely due to a faulty exit sensor. The two apps use different methods to avoid double counting of laps. The official app needs the exit sensor to be triggered before the next lap for that car can be counted. The exit sensor is inside the track base piece at the opposite end to the start/finish line. The Magic app does not use the exit sensor in this way... instead it requires a time delay before the next lap can be counter.

 

Causes of a faulty exit sensor can be:

 

1/ Internal plug and socket connectors not seated correctly.

2/ sensor board inserted 180 degress rotated... so lane 1 and lane 2 sensibg is reversed.

3/ internal fault on circuit board (unlikely).

 

Apologies for delay in providing this input...

I dont understand the issue here, for clockwise tracks I place the powerbase with the electronics module/block on the outside of the circuit while for counter clockwise I place the powerbase with the electronics module/block on the inside of the circuit. I slghtly prefer the inside configuration (counter clockwise) since the layout takes up marginally less space.

 

Makes perfect sense to me!

Yep the ARC PRO powerbase mod (either of the two shown on slotforum international) put the polarity of the digital signals on the two lanes into phase matching. Hence, 2-into-1 chicanes and unmodified LCLs will then function correctly for the system operating in digital mode.

Thanks woodcote for the informative update... so at least the issue is known with a solution in sight... many thanks

Over the years every Scalextric product I have purchased has functioned perfectly and looked great... well that is until yesterday... when my new Aston Martin DB5 C4029 arrived in an amazing metallic black paint finish... its chrome plated boot lid was missing... and I have learned that others have the same problem too.

 

Might Hornby make available some of the missing parts please? It would be a pity to waste resources by shipping nearly (but not quite) perfect model cars backwards and forwards under warranty... especially when the missing part could be easily glued into place by the user. This is such a nice design... but it does need its chrome plated boot lid please!

i wonder if by any chance you have the pit entry and pit exit the wrong way around... only theentry section has a sensor... just a thought?

Hi Woodycolorado,

 

So you have sorted the problem with the ARC PRO... but you are still getting power interuptions with the ARC AIR?

 

Do the problems occur when you race two standard Scalextric analog cars against each other? The ARC AIR has a separate current sensor for each lane so if either car is drawing too much current... I believe the power shuts down. Adding a larger transformer might give more even power... but the current sensors will still trip at the same current value. Of thecars you mention you own, the Scalextric ones are likely to run with the lowest current... do two Scalextric cars racing against each other cause the problems you mentioned earlier?

In case anyone experiences problems similar to above and plans to reposition the IR LEDs on the underpan of their SSD cars... there is a brief summary describing how the ARC PRO start-finish sensor operates... via the link below...
