light/sound/motion/info

Fairly simple circuit sculpture I call "Where and When". Couldn't get all of this to run using one microcontroller so the GPS and OLED display are running off an ESP32 Mini (bottom board) and the buzzer, servo, and blinking LED are running off an ESP8266 Wemos D1 Mini. It takes a couple of minutes for the GPS to get a lock and then a bit more before the info is displayed so I set up a delay on the blinking, beeping, and servo motion. The GPS is accurate to within about 2 meters and the time is listed as UTC (coordinated universal time - which is 5 hours ahead of daylight saving time in my central time zone. 89,99,57,0,B

Code Cleaning

Cleaned up the code and cut the number of lines almost in half.  

Ordered the mini version of the ESP32 to try with the project.  79,85,42,0,B

pass'n'fail

Got the code figured out to change how the info is formatted using an ESP32 microcontroller and OLED display - but I couldn't for the life of me get the GPS to work with the smaller ESP8266 Wemos D1 mini.  67,89,49,0,W

Arduino GPS

Took all day to get this working.  Now I'm trying to figure out how to change the format of the time and date display.  81,88,47,0,B

GPS

Figured out that the only way to get all the unnamed ranch roads on my new GPS was to download the topo map for Texas from Garmin  (I bought the Garmin GPSmap 62s because it includes an altimeter function just in case I decide to take up powered paragliding).  Took 2 hours for the download to complete even though the progress bar kept suggesting that it would take anywhere from 6 minutes to 58 minutes.  While that was working, I trimmed about a half inch off the pot studs on the rocket stove and cut a steel "skirt" from another little junk tank I found.  Just after the download completed, I went outside and checked to make sure it all worked and I heard some cranes way up high flying their migration route south...without a GPS.  65,88,57,0,B,.26
