Bernd:
Thanks Bill. I fixed it in my orginal post. Works now.
Sorry guys, fat finger syndrome. :wack:

Hmmm, I am please so many people have chosen to respond to my topic with variation of an anemometer.
However, and this is my fault for inappropirate choice of topic title, what I really wanted to do was to draw attention to the potential of using a pukaru keyboard for simple interfacing to PC etc.
tumutbound:
I'll reply on topic then. ::)
I can see no reason why your scheme should not work for wind direction.
I'm not sure if it will work for wind speed, it would depend on how quickly the keyboard can respond to a key press.
How many RPM will an anemometer get up up to in a strong wind?
Well mostly on topic.
Here a high tech option with no moving parts.
BillTodd:
The principle problem with using a keyboard is the way its input is handled by the operating system. In a multi-tasking system like windows or linux the key inputs will be passed to whatever application has the current focus, so unless you are prepared to dedicate a pc to the task of wind speed monitoring, it's not an idea solution.
Serial inputs (com ports) are useful because the driver usually takes care of unused data without causing too many problems. Parallel ports (printer ports) can also be used but usually require some extra hardware knowledge. Sadly both ports are disappearing from new machines, as they are replaced by USBs. USBs requires a ridiculous amount of software at both ends to use natively (i.e. as a Human Interface Device), but at least there are cheap USB-serial adapters that turn them into comports.
