I'm looking forward to it!
Hi, yes that's right. Connecting the ADDress pin to the positive rail gives the second MPR121 another address than the first one, where the ADDress pin is connected to ground. Like that the Arduino can distinguish between the two
Hi, I'm looking forward to see it! The 1 cm wide copper tape will also work for longer handles, but as the space between the electrodes increases, the chance of no touch being detected rises because you could touch the handle in areas where it is not touch sensitive. So I would suggest to keep the gaps between the copper tape electrodes rather small. In the Milan-version the electrodes were 4cm wide with 5mm gaps in between.
