it's solar powered... but the good thing is, it's spring/summer already, so there's lot of sun.
very soon-ish I think, but the things we are debugging etc are not completely in my personal domain so I can't estimate with 100% confidence how long it will take (as you've already noticed most likely) . It's tricky system/sdk/host related stuff, as you will see. Or maybe not -- it's the type of stuff that if we have done our job correctly looks extremely simple on the surface of things and you will wonder "duh, isn't that the way it should always work? it's so obvious!", but making it work that way behind the scenes is quite complicated and non-standard. Thus when wading in uncharted waters we've gotta watch out for crockdiles and other nasty surprises etc. (sorry, I watched 20min of Bear Grylls, latest thing on Neflix last night, so I am metaphor prone at the moment. )
