    Hi Harm,
    I would be interested to see what results you get with the 3mm acrylic. I made a keypad with key scanning, which worked fine with a thin covering, but I had varying results with 3mm. I also needed some of the buttons to latch on. In the end, I used an Atmel solution which works very well

    John

    Hi John,

    what kind of results do you want to see
    measurement values?
    a video?

    latching is, of course, no more than a software thingy

    Regards,
    Harm

    Hi Harm,

    I was more interested in what material types and thicknesses that you were able to get reliable repeatable results from.

    It's called 'plexiglas' in Dutch, a more formal name is Polymethylmethacrylaat.
    Both 2 and 3 mm transparent give good results and even 10 mm works.

    That's as far as it will go.

    Question: at the moment my uC and pads are on the same PCB (just for experimenting purposes) and I find that touching the traces between the pads and the uC results in a response.
    I'm considering to have the pads on a separate PCB, so make it two PCB's, to reduce this unwanted behaviour. Then I'll have to wire the PCB's and this might cause more problems than it solves like interference between wires.
    Should I shield each separate wire?

    Regards,
    Harm

    I made my board in 2 parts as you suggested with pads and leds on top board.(illuminated pads) and a uc board underneath with pic16f723 & relay outputs on the lower board and connected them with 2.54mm pin header and sockets. The top board was double sided with the pads on top and traces below.
