Not too long agos I tore apart an NFC lock from IKEA, and someone ran with the idea and connected the controller to the Arduino IDE. While the Rothult is nothing like high-security, it is neat to see that a lock can become another accessible tool. The coolest part, in my opinion, is that someone could catapult off something I did and make it better.
Some of the buttons in Adafruit's Bluefruit Connect app were more useful than others, but some became obsolete. I reprogrammed button two to stream live readings to get a better idea of what was happening in the device. To make things easier, I started formatting my messages to match my screen, which was 35 characters wide.
I repurposed button three to mute vibrations. Even during the testing phase, there were times I wanted to turn off notifications. The most obvious case was when I was driving north on a highway, and didn't need reminders.
If I get to an implantable version of this product, it will have wireless charging, and I wanted to install it early and work out bugs soon. The first bug was that the coil/charger I picked was for Apple and wouldn't power a simple 5V device. I had to discard the equipment.
When I tested the wireless charger, I may have created a short, or damaged a board connection because the battery ceased working. I could measure the voltage on the wire leads, but the Arduino refused to work without a wired power source. My tracking revealed an open connection between the battery and the BAT pin, so I installed a short wire between these points, and I got functionality back.
Even with the electronic components mounted to a base, they were still vulnerable. I designed a simple lid around the base with corresponding holes and an opening the same size as the base so I could nest it within. I used some metal standoffs to keep the base and lid spaced, but due to a miscalculation, the two parts don't sit flush.
The rest of the summary posts have been arranged by date.

It is good to know screen width

Remotely muting vibrations

Unusable wireless charger
When I tested the wireless charger, I may have created a short, or damaged a board connection because the battery ceased working. I could measure the voltage on the wire leads, but the Arduino refused to work without a wired power source. My tracking revealed an open connection between the battery and the BAT pin, so I installed a short wire between these points, and I got functionality back.
Testing for a bad connection
Even with the electronic components mounted to a base, they were still vulnerable. I designed a simple lid around the base with corresponding holes and an opening the same size as the base so I could nest it within. I used some metal standoffs to keep the base and lid spaced, but due to a miscalculation, the two parts don't sit flush.
