So in the spirit of this community and not just to focus on the Reddit... issues... I thought it might be nice to get a topical conversation going in here.
Basically, what open source projects are you currently working on or are you heavily involved with?
I think it would be nice to see what projects people have on the go, get some publicity out there and otherwise talk about stuff that we should be discussing here.
Not the more normal FOSS project, but I keep plugging away on Speeduino an open source (hardware and software) Engine Management system (aka ECU). Started it way back in 2013 and it just continues to grow in terms of community and contributors.
We have no way of accurately tracking how many are in use, but there's at least 4000 of these units out there these days, which is a number I'm pretty proud of for a hobby based open hardware project.
