So... I got an idea for improving the watch mod.
The original idea by N-O-D-E was to put the antenna behind the frontplate using a PCB antenna, which is great but leave me no room for resonant frequency tuning. What if I can tune the antenna anyway?
The idea is the following: what if we can build an antenna using the above part as a guide and as the front plate? Showing off the back of the chip (which is awesome) and leaving all the room needed for the tuning?
But Mattia, you say, how do you protect the watch now that we have a big gaping hole in front of the screen?
UV curable resin.
This will cure perfectly clear and fill all the needed gaps, with the added benefit of making the frontplate and the antenna a whole thing.
But Mattia, you say, how do you glue this new frontplate to the watch?
2mm wide double-sided tape usually used in smartphone repair (again thanks to N-O-D-E for the idea).
This new design should solve almost all the shortcomings of the old version:
- Buzzer gets back in place
- No scratches from the 3d print
- Improved range because the antenna is not behind all that metal
Let's see if it can actually be done...
