Unusual functions of cheap parts

Yeah. I have some extra instruments not doing anything, if you feel well enough not to use that as an excuse. I get stuff real cheap on eBay, and sometimes Harvard types are too proud to use it. And they also give me stuff nobody wants. A perfectly-fine HP oscilloscope, for example. Before anybody makes a remark, yes I've used HP scopes, used them in EE lab years ago, and have a 500MHz 4-channel Infinium plus an Agilent's 300MHz MSO on my bench now, so hide that smirk. :-)

People are funny. I had a 2 MHz scope once, did lots with it. You can use scopes well above their f_max with a simple envelope detector.

I had one with about a 30KHz bandwidth. The nice thing about it was that you could switch to driving the plates externally.

It got lost in a flood :<

As reluctant as I am to contradict a fart who's even older than me, if it's glass, it isn't a 1N4004:

Well, I've been known to disdain HP scopes because their sync sucks, and their knobs have terrible backlash, but at that price, hey, beggars can't be choosers!

You already have my snail mail address - third or fourth class can't be that expensive - I've gone some years without a scope - a couple more weeks certainly isn't going to do me any harm!

Thanks! Rich

I've used H-P scopes, too. They're perfectly fine scopes if you don't need triggered sweep[1]. Some of them even play games.

So, you think that a single datasheet covers all manufacturers, and all production runs? Once again, you show a great lack of understanding. I have several glass 1N4004 diodes in front of me.

You're probably wrong, of course, as Michael Terrell points out, but I'll have to admit that's an impressive list, and I love the manufacturer's logos, 26 of them, all lined up. Sigh, I only have datasheets from 20, stored in my computer. But, I have them from Won-Top, Leshan Radio, Gulf Semi, Formosa Micro, Dachang, and Bytesonic, to name a few they don't have, SFAICS. Plus, I have multiple versions from several of the companies. So there!

So many files, so little time.

Correction, they had Leshan Radio, listed as LRC. What a great site,** now I have 1n4000-series data from 35 manufacturers. That's got to be a record. Maybe I can stop now. [smile]

Sure. Why not? They are as big as the plastic versions.
