The worst part is thinking about best way to do it with whats in your just box i am sure my wife would wonder what the hell i am keeping this and that for but as we know we need junk ,i never buy wire its all from old electronics .
I can never be bothered building some thing messy then neat rather try my best first time win or loose and a nice size these days .
I did have another idea for replacing the dc motor yesterday and it slowed me up it was some thing you said in the past just want to see if i could get it to work .
(the use of steppers as synchronous motors as a great opportunity for NBTV)
I Hooked a bipolar stepper motor up to a Ac supply and wanted a pulley system to drive belt drive an un powered motor with the cd disk on that motor just as i could get perhaps a nice speed worked out if it worked the disk went 25 times around to 1 of the stepper motors rotation ,trouble was it was the stepper didn't have enough torque it would not turn the other motor and it was big .
The thinking behind it was it would be in sync with the 50hz so a slow clock rotating a strobe disk to make a higher frequency ..if i got it right.
Dam that torque.
I hereby pronounce you the Heath Robinson (Rube Goldberg for U.S. members) of NBTV!
And I mean that has a very high compliment indeed.
That sounds like a nice honor sounds like they have a bit of steptoe in them as well...need to like junk to reuse it .
I must try and get you interested in steampunk some day...

OH i do like steam punk its very clever i suppose NBTV is steam punk in reverse .
i saw a i phone hand cranked charger on a program the other day but not sure i like changing vintage electrics tack on modern bits rather a copy ...i never liked the idea of cutting open a vintage valve radio and turning it into a say a monitor ...a copy i like.... original its like murder to me .
The electromagnetic spectrum has no theoretical limit at either end. If all the mass/energy in the Universe is considered a 'limit', then that would be the only real theoretical limit to the maximum frequency attainable.
