I need 12 hours of ongoing education to fill out the staff development part of my teaching contract. So far I've found 9 hours of stuff I'd enjoy (analog & RF, mostly). Anybody got a line on some good enjoyable stuff I can do online for the other 3 hours?
I'd LIKE to get some smarts on FFT (Fast Fourier Transform) practical stuff, but so far I've come up empty.
