davedarko created this Adafruit Trinket Pro shield for the HP QDSP-6064 bubble display. The design files and source code are hosted on GitHub.
An additional temperature sensor in the form of the LM75 can be added to this bubble display shield. The atmega32p is capable of driving up to 40mA per pin, so with the display needing 5mA per element of a digit, it should be fine, since it will be a pulsed signal and there are 8 elements max.
