DGT Piece Sensors

ChessSpawnVT

Does anyone know the specific type of sensor used in dgt pieces? I'd like to create my own dgt compatible set of chessmen to use on my dgt eBoard. Thanks in advance.

I just asked DGT about the pieces sensors availability and this is what they replied:

"Indeed the sensor set can be purchased and would cost around 115 Euro ex. Shipping.

Shipping to Mexico will be around  32 Euro.

PayPal payment has a 5 mark-up.

Please also take note of see attached the instruction how to assemble the resonators into your pieces."

Seems like a "a bit" risky to install the sensors on your own. I had thought it wasn't a so delicate process.

Thank you for the information! Do you know how much dgt is charging for a complete set of E-tags?

115 Euros without shipping + 5 if paying with Paypal (have a quick look at my first post)

That's rather expensive given the diy aspect which I would likely mess up. Thank you for all of the good information.

You're quite welcome !

I was interested about making my own electronic pieces, too; but I'm almost sure I'll give up because the risk of screwing things up is much higher than my expertise at DIY tasks. We might wait and see if someone takes the plunge and provides us feedback about his/her experience.

I'm looking for a good price on a set of dgt Royal chessmen. There is a seller on Amazon who sells them for $245. Weighted cost just under $400.  I'm not at all certain the extra $150 for the extra weight is worth the expense.

DGT-compatible weighted pieces must be complicated to make, since metal interferes with the sensor coils. I read that the plastic pieces that come with the DGT Smart Board are the heaviest available and the least expensive, though not very pretty, by the way

True for the plastic regarding weight. They are butt ugly, IMO.  The company selling them on Amazon is based in Slovakia. They have expedited shipping ,< a week, for $18.00. I'm on the fence. There's a set of House of Staunton Margate chessmen that I really like for just $99. So many sets. So little time. Never enough money.

I keep seeing similar threads on here that tell me there are a lot of folks that want to touch and see real pieces on a board that would be close to an OTB experience now that everything has mainly shifted to online play.

Not sure if any of you saw my project on kickstarter, but I've come up with a way to incorporate real chess pieces you can use to play your favorite iPad chess apps. 

Think of it as a "poor man's DGT"

It's scaled for a standard 9.7inch ipad or similar sized tablet, works with any app, there's no pairing, it's portable, and will retail for $15 USD (plus shipping). Kickstarters will get a reserved copy!

Take a look at the project here! The campaign is almost over but there's still time for you to have an early shot at the product!

That's an unnecessarily complicated design. You could just use photoresistors in the board, that way you wouldn't need anything in the pieces, you could just use normal pieces.

(Ok, but the board would have holes in the middle of each square.)

The holes would be a bit of a problem, unless they were made in some way so that the hole was hidden. There has to be something simpler. RFID smart tags perhaps.

Ok, that's true.

I was just thinking that there's no reason not to be able to use any pieces you want... but yeah, the holes might not look nice.

Holes can be small by perforating a covering material (maybe with chessboard printed on it), so you have many tiny little holes instead of a big hole.  But the problem I ran into was shadow rejection, it made the e-board unstable in real play.

 

As for playing with weighted pieces, here's my DIY e-board:

https://www.youtube.com/watch?v=uJqjMlebuHc

It uses regular weighted chessmen and saves PGN to a USB thumb drive.  Another video at an earlier stage:  https://www.youtube.com/watch?v=0Y8NTp1wk2s (same e-board, but without USB feature and with more bugs).

 

Oh, I should add that the e-board allows illegal moves and undos (the software was initially designed for USCF scholastic tournament play, and sometimes check isn't addressed before a move is made, so moves may have to be undone. Also, sometimes, (especially) the knight is placed in illegal locations.  In USSCF tournament, illegal moves are allowed if gone unnoticed so the e-board can handle that.

 

I've been using my e-board more than the DGT e-board because of the USB thumbdrive support. The DGT e-board is a bit of a pain because the only way to get a game off of it is to download to a computer.

Oh, ... just watched the video and realized that I missed mentioning a bunch of things... my e-boards also..

1. record move times (the little line above the PGN is movement times),

2. runs for hours on 6-AA batteries (also has external power plug, next to the USB connector),

3. the little LCD display is unnecessary to the board's operation (it displays debugging information),

4. connection to computer is also unnecessary, in fact, normally, it doesn't output anything to the computer and can run faster; just for the demo I've enabled it's debugging output.

5. it "learns" as it is being used by recording unexpected movement sequences (for later downloading to computer),

6. The on-board non-volatile memory stores a lot more games because I don't just save source-destination squares.  A lot of times, only need to save the destination square (and that's only 6 bits; there's even more room because only 1 color is moving...)
