hi may I first say, I'm semi retired now but my training was electronics / design,physics was my best subject really I've personally seen various types of 'lights' specially in Wiltshire UK, tonight i saw something very close to what people probably call a will o the wisp, a flickering...

Hi Jeff.. I know..its all just 'words' isn't it.. maybe watch Enter the Dragon again as a poor substitute But would you be able to 'see' when chi is being truly used, and when its brute force? I'd pay to see it too, provided they don't permanently damage each other..

If you can use circuitry with op amps its more design-controllable. What about standard microphone amplifiers chips, designed for running from piezo electric audio mikes? The frequency range limits could be adjusted by altering any capacitor sizes.. I seem to remember piezo voltage output...

play safe Hi cepheid me an old :approve: engineer used to transistors (remember them?) If the shutter is inductive (a coil) then I might run it anyway, from a transistor separate from the opto device, but run from its output in some way perhaps via a base resistor (etc...). Thats merely...

is chi chi! This is my first post, having read all yours, I feel yes I do have some input but plase go easy on me, I'm only human o:) writing what turned into an essay... I was a development engineer in electronics for 30 years, always fascinated by the 'unexplained' in all areas, because...
