Hi Jim, Thanks :) I've not put any details up yet, though currently just using a regular Pi Camera 1.3. Its easy to take photos using the "raspistill" command, though I wrote something in Python. In the end should probably just have kept it as a shell script for simplicity.
Lots of fisheye style camera options around too. I'd like something of a slightly wider angle lense, but with the sharpness and colour of the Pi Camera 1.3. The Pi Camera 2 is wider, but the results don't look so nice to my eye. Good luck! Alex On Sunday, 26 January 2020 01:52:49 UTC+13, Jim Nagle wrote: > > I like this project!
