You know those holes are probably small enough that milk would not drip through because of surface tension, right? Which gives me an idea… with an array of different hole sizes, you might make an instrument for estimating the surface tension of milk. Or whatever else you are brave enough to S.H.O.V.E.L. Along with a graduated cylinder and an hour glass, you could also estimate viscosity (flow through one of the holes per unit time).

Mmm, those time travelers were tastEE! Hey… what does this say? “If found, please return to Chicxulub.” Huh. OK.

Thanks, I would appreciate it. I haven’t found anything similar (programmable from an Arduino).

AD’s website shows it in production and octopart shows suppliers with inventory… perhaps it was only mostly dead and true love has brought it back to life? Any chance of more?

Well, synaptic installed nodejs without fussing. There’s some C examples of pin I/O installed in the default user account on the pcDuino that are pretty basic; I can’t imagine it would take more than a weekend to adapt this Raspberry Pi GPIO module to the pcDuino: https://github.com/EnotionZ/GpiO using the examples as a template. Mind you, I haven’t verified that the example code works yet.

Hi Pete (and all),

Instead of using a magnetometer to determine orientation, you might consider using a search technique developed to deal with the big sky surveys (SDSS, LSST); it takes pixels from an image, finds centers of features (stars/galaxies) and uses the relative lengths of 4-tuples of nearby features to infer the orientation of the camera (and lense properties that affect the mapping). The approach is described in this paper and there’s a really good video presentation and slide set to go with it. Plus, there is source code and even a free web service available. Your tax dollars (US NSF, US NASA, Canadian NSERC) at work!

Wow, this is as easy as shooting fish on a Volvo. Oh, wait… this is shooting fish on a Volvo!
Then the car ran out of gas and the gathering crowd made the Greater Corpus Christi Fish School and Lobster Train increasingly anxious. “Look,” shouted Tex from atop the vehicle, “one of them has butter and a knife!”
