INTERFACING HC- SR04 ULTRASONIC SENSOR WITH ARDUINO
If you go to tutorial on the adafruit GFX library, there's a link that will generate the array for you from a .bmp file. The trick is you have to use Windows Paint for it to work. Even though other software says it saved it as a .bmp - im looking at you adobe.

YW, it helped that I had a bag of them on my desk, since I needed one for another project. Otherwise I may have overlooked it as well. ;)
found bug in the HB020_Badge_A sketch, I set my Mobile hotspot to act like a badge by giving it the SSID of HackerBoxer_T3chG1rlMN, and it showed up just fine. But when I turned the hotspot off, to replicate being out of range, it still showed as a tagged ID until I reset the badge.

I made some revisions to the hardware, switch not jumper, big cap hidden under display and of course the ring of neopixels. Firmware revisions; different display patterns to accommodate the neopixel ring, and adding a splash screen that pops up twice duning the main loop.
