Making a pen for a digitiser tablet - calcomp DB3
I had some success making a pointer device for a trust digitiser last
year. I didn't actually need one for that device, I was using it for investigation. The tablet I need a pointer for, because they're very expensive to buy, is a Calcomp DB3. When I came to investigate this board, I couldn't find the HF signal to feed the pointer as in the trust device. Of course it's possible the calcomp doesn't work, I got it in an auction with some other kit 10 years ago! Anyone have any experience with these? Cheers, Alex |

Making a pen for a digitiser tablet - calcomp DB3
I think the puck is just a receiver maybe with an amplifier in it, and
the board itself generates the field. How does the trust pointer work? |
