My little project - Boundary Layer Sonde

That's amazing - thanks for posting up. It's a really good use for Quadcopters!

Do you have a graph of the kind of data you get?

This kind of this opens the door for all kinds of stuff (not just weather) - for instance you could fly to 'scan out' a whole area of ground. You could map out all the thermals, and with a magnetometer you might even be able to notice deposits of things under the ground.

Of course, nobody's written the code to control any of those from Espruino yet.

Modtronix have kindly sent me some of their SX1276 boards (which should arrive in a week or so). Not sure when I'll get time, but I do intend to try and develop a module for them.
