Quoth James Cameron at 2008-11-15 13:30... > What you describe reminds me of a very low frequency RF oscillator with > an audio tone added in. I'd like to see a photograph of the wiggly > line, as I suspect it is not a simple sine wave, Here are the photos so far, per Plutek's request: <http://www.flickr.com/photos/msmiffy/sets/72157609086659400/> I might pull the rotor off completely once I've put penetrating oil on all the rusty bits - then I'll get a close-up of the entire rotor. I'm pretty sure that the way that the line is marked would mean that the tone would run as a sweep between the lower and upper frequencies - and 25 times per second at that. Should be an interesting noise - especially once it's been fed into a synth ;-) > Does it start slowly? That I can't tell as I haven't powered it yet. Think I might replace the capacitor first - don't know what will happen if I energise a 40 year old capacitor, but don't want my office full of shrapnel. Rotor spins very freely so I'd guess that it would get to full speed quite quickly.
