I now have the temperature sensors connected to the flight computer, and all the software written to poll them, send the data to the attached PC, and display it there. Same goes for the various battery voltages which I want to monitor to see how well they cope with the loads and temperatures, and to have the option of switching the video camera from one pack to another (it will have 2 battery packs). Later the data will be incorporated into the radio data link, and will be logged to the SD card.
Here’s a screen shot showing the various measurements. For this test. the computer battery is a used alkaline battery, and the phone battery is near fully charged. The other batteries aren’t connected yet.
