The People: So, what did you do on Valentine’s Day?
Oli: I went to Warwick South Services on the M40. at 9:30am to meet a man I met on the Internet.
The People: Hmm.
Oli: To collect the oscilloscope I bought off him off Ebay!
The People: D’oh, you tease.
Was worried it wasn’t working to begin with, not having ever used one before, but with a bit of advice from Gabriel Oscilloscope Vendor, it all turned out ok.
It’s for a video I want to make to accompany a piece of music submitted to the GeekPop Festival, whcih you can just about hear tinkling away in the background.
Yes, I could have used a digital oscilloscope on the Mac, and which I do have several flavours of, but like analogue synths there’s something much more satisfying about knowing that there is a real stream of electrons being deflected by the audio signal, and that it’s really flourescing the crt display. It looks great actually, not done any justice by crappy Youtube compression.
Not only that, but this oscilloscope is so old it actually have valves in it – gawd knows what it does to my electricity bill when I switch it on!
