You beat me to it! I figure SCOPRION is one of the products of SprakFun.

Everything I know about inter-jurisdictional law enforcement I learned from “Dukes of Hazzard” reruns.

Reminds me a bit of this story from a year or so ago—– http://www.pcmag.com/article2/0,2817,2387447,00.asp

I was wondering that too. Freescale’s appnote AN3747 says that with large (finger-sized) pads, it should work through a 3mm dielectric. I just measured a couple pieces of window glass I had handy and they were 2.0 and 4.0 mm thick, so I guess the answer is, maybe?

Those are logic-level translators. It’s a super-simple way to do bidirectional level translation on an open-drain line. I can’t find the nice appnote that TI (I think) had on the technique, but here’s an article from Maxim.

Even-numbered copters are easier because you can balance out the rotor torques (half the blades turn CW, half turn CCW). But tricopters exist too; they use a small servo to angle one rotor to adjust overall torque. William Thielicke’s “Shrediquette” copter is a good DIY example.

You can’t fool me, young man. It’s current sensors all the way down!

This seems like it’s probably a great chip, but is there more information on it available? The PS-MPU-6000A.pdf spends pages and pages describing I2C timing but says nothing about what settings, modes, data the chip might send, what its registers are, etc… do I really need to go through the whole request-information-from-Invensense dance to get some basic datasheets?

Actually magnetic materials saturate also (steels, etc). Permanent magnets come in a range of coercivities— many can be partially demagnetized pretty easily, using fields no stronger than their own, or even just by removing them from their low-reluctance magnetic circuit (which I guess is what’s happening with steppers, but I don’t know much about steppers).

I’ve tried a couple of programs but the PDF doesn’t display in any of them (most of the text is replaced by fuzzy black bars).
Could someone who can read the file tell me what kind of protocol the module communicates with the host with? Does it take BT-HID messages as they’d be transmitted on the bluetooth channel, or is it restricted to some subset of the protocol?
