I wanted to jump into coding for the new microcontrollers, but I had to start with Nordic's Software Development Kit. I could not find a clear starting point, so I installed their nRF Connect suite, and then SEGGER, but neither was clear about how to compile for a microcontroller. I played around with SEGGER's Hello World example to familiarize myself with the environment.
I realized that I was doing the same thing that had stopped many other implantable microcontroller projects, and that was wanting to do everything perfectly. The programming was holding me up, but that told me it was not accessible to everyone anyway, which was the whole point of the project. I am going to move forward, and probably use Arduino, even if that does not support OTA updates.
I set to work getting the microcontroller to work with Arduino. I was using an inexpensive clone, so I had to hunt for relevant tutorials. Luckily, I found how to enter the bootloader mode and check my version. I updated that and tried to send a "Blink" program, but the board stopped responding after that.
A little troubleshooting fixed my unresponsive microcontroller. Shorting the RST pin to ground did the trick. I checked my hardware by downloading an example using Serial communication, then used that to figure out which pin the onboard LED was on, and also discovered a couple of pins that cause an immediate reset. I downloaded a sketch that let me toggle the LED via Bluetooth on my iPad.
I added an oversized basket to the roof of my car. I picked the kind of luggage rack I usually see on sleeper vans and off-road vehicles. There was a lot of stuff to bring to Grindfest, and I do not want anything to cramp my wife or me.
Empire Records aged surprisingly well. It had the baggage you would expect from a mid-90s teen-drama movie, so fair warning. Benjamin and Joe picked this movie to promote their comic, Dead Air, which just reached its third chapter. The comic and the movie both have a feeling of found family, rooted in a shared love of music. I read the first two issues, and I am eager to see the third.
The rest of the summary posts have been arranged by date.
