I sometime changed red/green leds (especially on fidelity) but more often, I just moved the led with one finger and it worked again.

I know that too from a Fidelity Excel Mach III! Had this also with a H&G Exclusive board (older version)

I am probably unlucky but I have one CC9 with the sensory system out of order (one square seems to be pushed permanently).

I sometime changed red/green leds (especially on fidelity) but more often, I just moved the led with one finger and it worked again.

I changed one time a magnetic sensor on a Conchess.

I never had any problem with my old mephisto exclusive except difficulties to switch it on with a recent module (magellan) after a long period of non use.

I had many low cost devices but never had a problem with the sensor system except a generic problem of "large bubbles" (due to bad glue quality ?) under plastic chessboards. It often happens with Yeno.

Hello Mike,


Quote from: Mike Watters on January  3, 2007, 03:01PM   

You seem to have been luckier with pressure sensors than I have. The old Fidelity's were not without their problems in my experience. Fewer problems with later boards though.

Fidelity pressure sensors are ok here, even the older ones (CC9, CSC Elite, Mach II/III)

Slight sensor problems i had with a SciSys Turbo 16K and a Super Forte. Some of my Novags (and the Turbo 16K) show not correctly fastened board surfaces; but that doesn't matter the function.

Quote:

need replacing. I have not, yet, had any problems with Mephistos, Novags or Saiteks. Not sure about CXGs?

regarding reed switches:
With CXGs i had relatively many defective reeds (considering, that i don't have so many CXG magnetic sensory boards)

Had one defect in my Commander and one in a Chess 2001 (the switch is not working, but you can hear the clicking sound, so maybe only a bad contact)

In a Saitek Corona, one reed stopped working, but when i went to repair it, it mysteriously worked again!

With Mephisto and Fidelity, i had one defect each; so i would say, it's well distributed! 


regards,
Robert

The oldest magnetic sensory boards are a bit of a worry on account of failing reed switches eg the Conchess machines and Sargon ARBs. The contacts seem to  oxidise if they have had years of non-use and the reed switches need replacing. I have not, yet, had any problems with Mephistos, Novags or Saiteks. Not sure about CXGs?

All the best
Mike

The Grandmaster(Excalibur) is magnetic sensory with a plastic board and it seems to work just fine.

And isn't the Novag Robot also magnetic sensory?

The disadvantage of magnetic sensory: the reed switches are by far more prone to defects than pressure sensors!

Until now, i had only 2 computers with a not perfectly working pressure sensor (too easy to trigger; only the weight of the piece is enough!); i would not call them defective.

But about 4 or 5 (definitely) defective reed switches!

I assume, Mike could tell us more... 


regards,
Robert

I am surprised by such a question.
Magnetic sensory is for me a lot better.


Same is here...

1st choice - Magnetic sensory in wood
2nd choice - Magnetic sensory in plastic
3rd choice - Pressure sensory
4th choice - DGT type with a PC/laptop
5th choice - Staring at the screen

But this is just my preference.

In fact, I think that you never have the choice:
  • Wooden board = magnetic
  • Plastic board = press sensory

The only plastic board I have with "magnetic sensory" is the Kasparov Blitz... and yes, it would probably be more practical with Pressure sensory squares.

Best regards,
Alain

Hello, I think that

press sensory  ... is not possible for wooden boards 
press sensory  ... is a mechanical system and so I think we can hope more defects

on the other hand,
press sensory  ... errors are avoided dragging the pieces
the newer chess computers have a very sensitive press sensors and it's a good advance

This is a interessant question...

What´s the best option for eletronic boards?

Magnetic sensory ( wich reed switch) or press sensory?

In my oppinion "press sensory" is the best because:

1- Minimize danger problems (reed switch make problems every time than "press sensory")

2- Wich "press sensory" is possible play blindfound, because the board dont need know all pieces position for play.

3- More and more ;-)

Tell We oppnions
