Excellent channel! Keep it up--I anxiously await your new videos just the same as I do the ones from that crazy Aussie bloke!
Anyways, the main reason I'm here is because I watched your video where you used your scope to measure the speed of sound. You said you'd be "chuffed" if your viewers would give it a shot and link their videos. Well, I did just that, and was able to successfully measure the speed of sound with both my Agilent AND Rigol scopes, and put the video up on youtube. I wasn't able to successfully post the video into your comments due to youtube's over-zealous spam filtering. (I can see my message when I'm logged in, but if I'm not logged in or logged in as anyone else, it doesn't appear in the comments) Grrr... youtube....
Also, I had to look up what "chuffed" meant on google. I get a kick out of South Africanisms. (or is that one more English?)
Anyhow, here's the video:
