From what I have read, firmware is basically “ready”. There is no space left for new stuff and as long that it mostly works, we wont be seeing much development.. Smaller sample buffers might be possible (by James, because fw is closed source), but i’m not sure that is it also something that could be affected from the app (which is open), like James told about logging intervals..

Oscilloscope would be nice (but expensive) and current shunt would not cost anything.. Piece of (probably existing) wire should be enough in most cases.. It seems to be bit bad thing for mooshimeter, that people see graphs about electrical measurements and think that those only come from scopes. Mooshimeter should be taken as 2 channel multimeter, that can log. It can do it bit faster compared to human with couple multimeters, pen and paper, but it would not make it an oscilloscope.. Buffer mode in graph view might raise the hope even more, but really it still limits your measurements to few hundred hertz with shooting in the dark as a trigger mechanism. It is much more though than most multimeters do in the same price range.
