I was doing almost exactly the same thing, although I'm just dumping it into a mysql db locally. To speed things up as I prototyped, I was using python to poke around the data once I'd curl'd it down from the server. Once I dropped the output from c…
I might be misunderstanding but it sounds as if you'd be depending on a rotation around a vertical axis as the signal, which isn't a face-to-face rotation of the twine (ie, if you start the side with the 'twine' logo facing out towards the room and …
Brian,
I was kludging some things together in a similar fashion I think. I couldn't get your script tho; not sure if I'm just blocked ATM due to some network settings as I'm on the road tonight. Can you let me know if the HB location is working, ot…
As a 'related but not exactly what you asked' note, once the breakout board support is in place on the 0-3.3V signalling, I expect you'll be able to use items such as the current/voltage monitoring units such as this small 0-30A split core CT which…
Yes. You can use a CT (current transformer) with a NO or NC output and a settable trip point. I'm sure there are cheaper options, but here's something I use in commercial/industrial installs that's in the 'lower scale' of current settings. You'd tie…
The breakout board has 3.3V (unused ATM, until analog signaling is built into code in an upcoming update) plus a pair of pins for a circuit (NO/NC). You can take any Normally Open or Normally Closed switch and put it inline between those 2 pins, an…
The twine aux power port is a micro, not a mini.

Mini left, micro right
You can buy an adapter or a micro cable or micro-pin'd supply fairly easily, tho.
I have access to a laser cutter & 3d printers at my hackerspace, and I'd be happy to play around w/ some options if there was access to the model of the existing case so I don't have to reinvent the wheel as far as that goes
