I'm pretty good at interviewing, actually. You see, when you know something there is no reason to have the problems you do.

No hypocrite. I don't much like your type though; stupid and arrogant.

...and the plummeting costs. The VS option on a tool with a 3/4HP motor seems to cost $100-$150 retail, these days. It'll probably be standard (where it makes sense) in a few years.

Three.

One to hold the bulb, and two to turn the ladder :-)

I thought they banned ladders in the UK? No need for one, after they banned decent lightbulbs. :-)

That was fun! (3-phase squarewave digital generator, feeding 2-pole filters for wave shaping.)

Whenever I play with these type circuits I always want to generate a

3x squarewave and subtract it from the fundamental to cancel the 3rd harmonic, easing filtering.

The 2nd impulse is to integrate the waveform into a triangle wave, then round off the peaks with diodes (LEDs are nice), then filter.

Those always start getting messy, so that's when I drag out the weighted resistor-DACs and counters or shift registers to smooth out the steps.

By then you've gotten tired of all the parts and go back to the original...It's the circle of life.

It's probably more than pure enough. Thanks for posting it.

From which manufacturer? Searching on that string alone gets me the NXP part, but the data sheet identifies it as a Philips part from

1996, only 14 years ago, which isn't all that relevant to what a modern microprocessor might do.

Is that what you think you were identifying? And if so, why were you bothering to identify it?

That was never my assertion. You keep on claiming that I said that, but you've never produced a quote where I said anything of the sort, and I can only imagine that it is delusion generated by your failing memory and defective understanding.

Since the only data sheet that I have found - without any help from you - was fourteen years old, not twenty, and - you tell me - from the wrong manufacturer, you haven't got to first base on making that point. If you can't point us to a data sheet to tell us what your favourite chip - whatever it was - could do back then, your claim is no more intrinsically credible than your fatuous claim that I said that Mark Weaver's job couldn't be done by a micro. Since you've got that totally wrong, your opinion about what a twenty-year-old micro might - or might not - do, can't be remotely credible until you can back it up with a real data sheet for a specific micro, manufacturered by a specific manufacturer.

You are a posturing windbag, and no amount of calling me "stupid" on the basis of something you imagine I said is going to make you look any more credible.

You're such a liar, Slowman.

I found it in about 10 seconds. I can't help it if you're so incompetent that you can't even do a simple web search. Acutally, I didn't think the datasheet would be on the web, but it is.

You're projecting again, Slowman. Yes, you *are* stupid. You work hard to prove it every day.

He probably thinks the Signetics 'Write Only Memory' was a real component.

You suppose correctly, but it's not just a word, it's a word which
describes the way in which the device is used, so it's also a word
describing fact. 

That is: a pot, if it's wired like a rheostat, is a rheostat no matter
what you choose to call it.

I can't say that I've ever been tempted to design them into anything that I was thinking about building. There does seem to be a market though - krw's memory would be constructed exclusively with these devices or their biological equivalent.

Actually, that is the "synthetic sine wave" where you generate a three level approximation to a sine wave

This is easy enough with an H-bridge driver, and seems to be popular with people generating 50Hz and 60Hz approximations to mains power. It should have no third harmonic content at all.
