The AR draggable power-up functionality has now reached a stable state that’s good enough for a version 0.1. Updates to the code made it more modular for multiple markers, for 3 element power ups, and now the power up rectangle that is placed onto the marker knows when it has done so. The power up rectangles only appear when there’s a marker in view. The next step will be to download the libraries that are used and make sure it works with the latest version of everything. After that will be making some new markers, and then merging the code with MQTT. Also, catch-up has to be done for the previous logs… oops. Well, by the time this is posted, the previous 5 are now caught up too.
Quick tech log to note that the instance is back up and running again, and the AWS credits missing was resolved! Did some high level searching on what next to tackle with that, and it will be learning more about Route 53, DNS, SSL certificate manager, and React Native. This will come a bit later though, the biggest priority at hand is to make this prototype work.
Board routing is done! Needed to do two iterations on it. The first iteration was routed without using the right dimensions on the outline. Oops. With the proper outline imported, everything needed to be placed closer together. Lesson learned: always import the proper outline (or close to it) as the first step. Alright, so the routing was completed fine. It is a 2 layer board with a copper pour on the back of the board. Tolerances for design for fabrication are 20 mils tracewidth, ample spacing at 10+ mils, and using longpads whenever possible. Vias are large like pads, so they can have a wire pass through them during the assembly stage. Next up is milling the board!
Schematic done for v0.1 of the sensor node! This is the most simplest design possible, with the barebones minimum. An ESP32 breakout, with headers to each side just in case, a reset switch, 6 LEDs, temperature sensor, speaker, and power boost board. All components are through hole at this moment in time. Pretty smooth sailing on this. Next step is to route the circuit board.
