Link error... I know the forum was playing up for me yesterday and it looks like it's doing it here too...

Copy and paste the following url;

interface.khm.de/index.php/lab/experiments/theremin-as-a-capacitive-sensing-device

Yeah I have seen this happen several times on other threads.

I have just posted a General topic called Humor with a link and it did not appear on the Forum.? "There's something strange in the neighborhood"
