If you have been keeping up and reading the updates you know that we ended up changing to capacitive touch. Capacitive touch has come a long way in the last year. We have had more progress in the last few weeks than all the effort we put to the IR version since the beginning. I know you all are hating the extremely long wait and I am really sorry. There are so many unexpected hurdles but I think we are past that now.
Capacitive touch will make this product so much better, I am sure you will all agree when the product is in your hand that the wait was worth it. The way it works is that there are small conductive pads printed in an array, on a thin clear film. The film is laminated on the back of a layer of glass or plastic. In our case we will laminated it in between a piece of 3.2mm thick Sapphire glass and a protective backing part. The print on the sensor film is color matched to the glass so that it is completely clear and the traces that go to each touch area are only 30 microns or .03mm wide so they are nearly impossible to see. Each sensing pad is about 4mm square and can be interpolated into about 25 positions in either the X or the Y direction. This may all be a bit much to absorb but it basically means the number of touch points on the keyboard will be just under 94 million.
Both the keyboard and touch-pad will be much better looking. The camera bumps under the glass will disappear and the base will be completely smooth.
The base must be made from glass reinforced polycarbonate so that it does not interfere with the sensor signal. This will reduce the weight a lot. We wanted it to be heavy to add to the feeling of quality but it ended up being a lot heavier than we wanted.
The plastic part that covers the Bluetooth antenna will go away eliminating the seams and making the base look even better.
The rechargeable battery will last longer and the device will charge quicker.
The glass will be safer. We were using tempered glass which is really strong but it explodes when it breaks. The new glass will be laminated with a polyurethane membrane to contain it if you decide to use it as a baseball bat. I don’t recommend it… We don’t want any lawsuits!
The new assembly will also be fewer parts so it will be easier and quicker for us to assemble. Fewer parts equates to higher reliability and lower cost, which doesn’t do much for you but it helps us stay in business which I like very much!
