Tom is designing a breath transmission system using a PC case fan as a optical interrupter –
“Breath” is a breath-over-IP phy2phy system. You blow on one fan (anemometer, whatever you want to call it), that data is sent over IP to the other side where a fan it turned on to match how strong you are blowing on it.
Once a fan’s internal coil is removed it’ll spin freely, making it a suitable for measurement/interruption. Read more of his development process here – Opto-interrupters for Breath

Begs the question (without wanting to sound negative, and is posed as a legit question) . . . how can this be applied to anything useful in the real world?
Also, wont the remaining kinetic energy in a fan when you stop blowing on it throw out the accuracy? Our breaths can stop instantly, fans dont normally.
I don’t know, its an interesting concept to explore, but its got very limited applications.
Well I guess the uses of the implementation are limited. But the idea of a cheap low volume air movement detector is interesting.
