Re: state of the project

[Robin V. <mls...@gm...>]

thanks philip (also for the fast reply)!

johannes, i do not understand much but.. sounds great!!
so you helped with (or made yourself) 30 such car conversions already??
wish you all the best with all that, and also hope your old team gets
together again! :-)

the main reason i wrote, was to see if i could help with some minor stuff.
as i remember you are all kind of low-level guys, mostly into electronics,
mechanic and C coding, while i am a high-level (usually desktop software)
Free Software developer. tell me if i could be of any help, possibly. the
only thing i would say where i have some possibility to help, is the
android app (the dashboard).. is that still useful for your current setup,
johannes?
