the Tricorder project

for measurement you can use your own integrated sensors.
use the white led as an emitter and your sensor of lightment as an absorber.
only you must integrate the funktion of this modul.

you send an permanent lightbeam and get an stroboskopic signal of the light-sensor.
now you can say one signal per minute is one rotation per minute.

sorry, i cant show you.
i cant publish images with an external url...

I think by default you have to post a certain number of times before you can include pictures or links, but given that we manually verify accounts now and havent had any spam since (!), we can probably get rid of that requirement

hmm, are image uploads technically classed as "attachments"? do you think there would be any issues if we enabled them?
