I’ve been using the instrument occasionally since receiving it from the KS campaign, and in the last week or so rather intensively. Early on I was completely baffled by its ranging controls and UI, being an old-school scope-with-knobs kind of girl, but am now beginning to feel comfortable with and even like it One thing I’d suggest is moving some things, in particular the peak indicator selection (none, lines, fill) from where it’s currently buried 4 or 5 clicks deep in “Preferences”, to buttons on the toolbar. I mean there are acres of space available, and this is something I like to switch fairly often. Visibility controls for the displayed measurements would also be better as buttons also, rather than being in “Settings” where people can go a long time without even knowing they’re there (don’t ask me how I know).
Another thing I’d love to see is measurements in mAH. I’d wager that most people using this instrument are concerned with battery life, but I’ve yet to see a battery data sheet specifying coulombs or joules. Yes, it’s a simple calculation, but hey, this thing is hooked up to a computer, so I shouldn’t have to do calculations just to get the basic quantity it’s supposed to measure, in a usable unit. If you really want to make me happy, let me enter a number in mAH for battery capacity, and display the projected run time in days/hours. Yes, I know there are a lot of other factors affecting run time like cutoff voltage, battery resistance, varying current draw with declining voltage etc, but trust your users to be able to enter a pre-fudged battery capacity number for a ballpark run time estimates.
Lastly, long-time measurements. This is crucial for a lot of users and applications, and we shouldn’t have to deal with scripts and other hacker-ish stuff - it should be built in, imo.
Thanks for creating Joulescope, I’m finally digging it!
