Quote from Jaume Martínez on April 17, 2021, 6:35 pmHello Certabo friends.
I would like to share with you my work. I wanted to hide the electronic chips and put the felt on the base, but I couldn't do this because the chips were too big to hide in the pawns. After asking Pietro, he gave me the opportunity of using naked chips. Once received, after several hours of carefully handwork, finally I have got my desire: electronic pieces with felt. The playing experience has become very better. At least, for me. My desire has been done reality!!
Here several images of the work with the pieces and the final result: https://photos.app.goo.gl/HZxzG3eSnJP27zQT7
Any doubt, feel free to ask.
Many thanks to Pietro! Without him this dream would not have been possible.

Nice DIY! Two questions:
They look like weighted pieces, haven't you had problems between the metal and the emisor chip? How have you isolated them?
Where can I find such beautiful pieces?

Yes, my pieces are weighted, but I don't have any problem with the detection. Probably because the weight in the pawns is not very big. Depending on the space I had, sometimes I used a piece of paper to isolate the chip, but not always, because the space was not the same in all the pawns. For the major pieces I inserted the normal chip (with the plastic housing), so they are isolated.
I bought my pieces in the ajedrez21 shop, they are available in black colour, but they are now out of stock, the next is the link: https://www.ajedrez21.com/piezas/4208-519-piezas-classic-2000010013012.html#/6-tamano-4/27-color-negro
My board is the Lucien Brown, 45mm squares, and the pieces are stauton nº4.
Thank you for asking. If any doubt, let me know.

Great work and nice outcome! I thought it would be nice idea to make a sticky post so everybody can find easy direction to do this.
I also take opportunity to add another document written by Marco (marc_one) he sent me here the main steps downloading the pdf can see pictures too.
Thanks to everybody for contribution!

APPLICATION OF CERTABO ELECTRONIC CHIPS TO A CHESS SET
- The green felt at the base of the chess is usually applied with vinyl glue. To remove this felt it is first necessary to moisten it with a few drops of water
- after waiting about 15/20 minutes, the felt can be removed easily
- the glue residues are eliminated with a cloth, always dampened with water
- here is the piece ready to be converted
- at this point, color the edge of the chip with an indelible green marker; this to better simulate the felt removed
- the original felt is replaced by d-c-fix adhesive green velvet (code F3480003). To cut the discs to size to be applied to the piece, you can help yourself with a set of dies easily available in the interet for a few Euros; these dies usually have diameters of 20mm, 30mm, and 35mm which exactly match those of Certabo chip sets
- The discs are prepared with the punch of the diameter corresponding to the chip
- Which subsequently apply to the chip on the face printed with the Certabo logo
- The last step is to apply the chip on the piece using its adhesive

Quote from julkal on May 19, 2021, 2:14 pmIn my experience, I can only advise against this attempt (with weighted pieces). I've been experimenting really long. Always with the same frustrating result: Some pieces were no longer recognized by the board. But that's not because the board has poor detection, it's just about physics. Metal and piece recognition simply do not always get along. I now have the chips directly at the base of the figures and a thin window leather to protect the board. In my case, some pawns just couldn't be persuaded to do their job......
Just for information: These are my problematic pieces:
Doesn't look that good, but it always works perfectly.

Thank you for reporting your experience, yes we got similar conclusion we also think it is the specific shape of the metal and more precisily the edge conformation.
To give more technical deatils, the board sends signal to chip this signal supply the chips which respond back and frequency used is very low and also big chunk of metal will not change much the efficiency of transmission. We also tested with huge ferromagnetic coils and this also wont' effect. But some specific shape of metal can result into a diffraction path of rf specifically is how the edges of the metal piece are made as if it matches specific combination then the metal can generate diffraction of the field it will not reflect back any signal resulting in the piece to be invisible to any detection system. Most of the time this can be overcome with different antenna size or changing distance, in your case I think when you drilled you changed a bit the edges conformation exting from this specific combination which could not be solved either way.
For those interested the theory is "Method of Edge Waves in the Physical Theory of Diffraction" which explains how the intensity of reflected wave is proportional to how the edges are shaped and not on actual dimension of the part. And i would call your set "Stealth set" 🙂 as this is effect is used to design metal object to be invisible to radar or other rf detection system. And would be good to know if had chance to see how the metal weight was shaped before your drill.
All the best
