Testing crystals
Last millenium I built a box to test Xtals and 555/6 timers - I'll see if I can find the circuit - it wasn't original, I pinched bits of the circuit from various places.

Who is using the Raven?
I should get some time to further experiment next month and I'll vote then. It's remarkable how things suddenly go from "hard" to "easy" when - with the help of people like Dean...

Getting a rotary encoder to work reliably
Because a gray code should only change one bit at a time, bounce will only be a problem it it lasts past the next bit change position. The effect will be dithering back and...

Detecting RS485 idle
If you give each slave 2 addresses that differ only by 1 bit (top or bottom is easiest) and you use the 9-bit system to mark address bytes, the overhead on polling is greatly...
