Technical update

Main focus points of project:
- functionality (making great progress, no worries)
- durability (update below)

The emi contact fingers providing the springy contact between the two parts prove not to be durable enough. See picture below, problem marked with sad smiley.


NO PANIC

I've done some research into pogo pins (gotta love 'm). These should also do the job, but because they are just surface-mounted, the copper beneath it becomes the next weak spot. However, there are pogo-pins that go through the PCB and provide a very strong connection.


They are about 1.5 times as thick as the pins of the phone itself. They go through the full thickness of the PCB and feel very strong even without being supported by the outer casing.

This is still under testing, but first impressions and primary tests give me a lot of confidence this is a good solution!
