I don’t know much about kobo or the software it runs. However it does appear to be very interesting and I’d like to try it out sometime, especially for free flight.
I’m currently working on a project for the OpenPPG unit: a custom PCB for a battery cell monitor with built in altitude measuring capability. (More on the cell monitor later when I make a little more progress) but for the altitude measurements, I can’t decide if I want to use a pressure sensor or a GPS module. This altitude measurement will be displayed along with the lowest battery cell voltage on an OLED mounted to the gooseneck bar.
I have a lot of experience working with pressure sensors for my variometer project. So I figured it wouldn’t be hard to add features like that to this PCB I’ll be designing.
