I've been thinking about this all day at work (LOL ......!!) And I think I know why all this is so. It's because the triac does NOT function as a wave-modifying device .... rather as a

The one we have here now is like that. The one where we used to live was electronic, sort of. The display, instead of being the usual mechanical stuff, was a small LCD panel which would sequence

Not necessarily. I have some other (rather ambitious) plans for my sound card that don't involve making it into a scope...

You should start a separate thread for this or someone's going to get confused (like me). I'd strongly suggest opto-isolators. Alien Steve

If you need an 8 channel logic analyzer (like an o'scope for digital signals), have a look at this: http://www.xs4all.nl/~jwasys/old/diy2.html It's been VERY helpful to me working on I2C and AT

thought about that... but was looking for a really simple thing using existing components. building a PS2V circuit takes me at least as long as measuring the phase shift point by point. of course if

the power company meters have a aluminium disk and 2 coils, one for voltage and one for current. (i reckon a 3 phase unit has 6 coils). this ensures that really the power is measured. the fields

That's how i did it.. but do you have any ideas on how one can get the phase shift on the screen? (If the scope can't calculate it of course) ST

I too say that, but i say there can't be reactive power. now, a phase shift in current and voltage, and no reactive power, can't be, can it? i bet a wattmeter would measure none, if it works as a

in europe you can get them at all major distributors like RS components and such. guess it is similar where you are. ST

Hi, The current design is in the group files folder "Filter with DC adjust.jpg" AD8400s tends to roll off around 600KHz, this is a common problem with all digital potentiometers. Using a FET as a

Hehe... Then we add some input conditioning circuitry and attentuators and such, and when we're done we'll have built ourselves our own digital storage scope. You that ambitious? I'm not, these days.
