Yeah, despite my misgivings, we kept him around. And what did it get us? After 10 or 12 years he up and quits! Off to do web stuff that will no doubt come to a bad end.

The pcbcore link doesn’t seem to work anymore…

I’ve just ordered another board from pcbgeek.com. I’ve used them several times before with good results; $90 for as many (identical) boards that fit in 200 sq. in.; max individual board size 7“x7”.

The board I just ordered is 3“x5”, so it should…

I’d like to try the Stellaris.

Thanks,

Gary

“ – didn’t lower the voltage much.”

Well, I said that it trims the duty-cycle, not the voltage. This reduces the average power, but this will not be reflected in a voltage measurement by a non-true RMS voltmeter. Most inexpensive digital meters will only read an AC voltage correctly if it is a…

If I read this right, your question is: Will an AC speed control intended for a router, work to control the temperature in a length of nichrome wire?

I think the answer is, probably. Most speed controllers work by cutting the duty cycle of the AC, which effectively reduces the average voltage. I…

So I already despise your registration screen. I fill it out, but don’t check the EE Times subscription box, because I already subscribe to EE Times, and anyway, this is Datasheets.com. So it comes back and says I must check the box, and, by the way, you have to fill out the registration again….

And the answer is… it depends. Depends on what your assembly house wants. Most that I’ve dealt with are already used to massaging the data from any format/origin/orientation, but if not, I’ve done the spreadsheet route too.

OIC, an internal assembly house. That explains it. Total…

So a nice holiday weekend, I decide to reorganize my home office and set up some extra equipment I had sitting around. I pull everything out, unplug all the cables, and dress everything up nicely. I add a network hub, and set up an old PC that I use occasionally, and added the power wall wart to…

A circle on a scope, and other shapes, are called Lissajous Figures. This looks like a good site for an explanation:

And Cody is correct, of course.
