Comment I use a PC to create (Score 3, Insightful) 291

The 'real' PC, used for design and engineering work, is not likely to go away any time soon, as all our technological advances would grind to a halt without it.

The PC will get more expensive as the sales volume goes down from hundreds of millions to hundreds of thousands of 'real' computers per year. but then, those of us who use PCs for real work have been riding the coattails of the gamers for a decade now.

Sexual orientation is becoming less important, especially to the younger generation. Unfortunately, there are still people, even parents, to whom it matters. Those people are the problem, not Facebook. Facebook is just one more avenue for a person's orientation to be revealed.

The best defense against your parents finding out about your sexual orientation from someone else will always be to tell them yourself, from whatever distance is safe.

Comment Here's what I have. (Score 2) 208

I've been doing electronics work in my home workshop for about 35 years. My workshop is equipped with the following;

I have 20 units of 36-drawer Akro-Mills parts cabinets, the kind with the clear plastic drawers. These have SMD components, through-hole components, nuts, bolts, connectors, switches, etc. I occasionally devote a parts cabinet to the parts for a particular project that I build a few hundred of.

Hand tools: I have a red plastic screwdriver caddy that's full of screwdrivers. About 80 different tools to open anything I may encounter. There is a very expensive pair of diagonal cutters and a nice pair of long-nose pliers on the bench, and some tweezers and an X-acto knife.

I have a Hakko soldering station and a Bauch & Lomb stereo microscope to see what I'm doing.

On the bench, I have a 3 digit digital voltmeter and a couple HP bench power supplies to activate my current project.

Next to the bench, I have a 6 foot tall rack with a Tektronix R7704 oscilloscope with appropirate plugins, a vintage Fluke 6-digit Nixie tube voltmeter, an HP 5245L Nixie tube frequency counter, a signal generator, an old HP spectrum analyzer and tracking generator, and a Nixie tube atomic clock.

You're very lucky to have a school that would teach that.
I built a similar thing (a frequency counter) as an 8th grader, using the RCA CMOS data book's application notes as a guide. And my dad was an electrical engineer who taught me a bunch. But I brought the counter into my electronics class and got credit for it, although I don't think the teacher knew the first thing bout digital logic - he was a TV repair sorta teacher.

My high school obtained a PDP-11 (with dual 8" floppy drives) while I was a sophomore. I was given free reign to use it as much as I wanted, with no supervision. I ended up writing assembly language and parlayed the experience into a nice job at the local university programming and building interfaces for a couple PDP-11s, then building custom S-100 graphics systems, etc.

For starters, Tesla came up with the three-phase AC power distribution system that has been in use everywhere in the world for the last hundred years. There's enough material there to fill a few rooms. I imagine we'll see some Tesla coils as well. Plus all the really exotic stuff, such as the proposed wireless power transmission scheme and the marvelous conspiracy theories about its suppression.

It's all fun stuff. The most interesting pieces I have are an IBM 704 module with eight IBM vacuum tubes, and a CDC6600 cordwood logic module (see it on Wikipedia). Just sold a Remington Rand tube module to a collector. Apparently, it was the only one from its type of computer still in existence.

I was just playing with some cores the other day. I found them on ebay a while back, two bottles each with 1.2 megabits of 1/64" diameter ferrite donuts. Add your own wire and sense amps.

These things would have been threaded with three 46 gauge wires each. They had machines to make that easier, but not quite automatic. http://www.nixiebunny.com/ibmcore/ibmcore.html
