interesting project.
rotation of the head during wind change is the next hurdle.

It seems to be held in by gravity at this time, with a tube slipped inot the
mast. I don't imagine it will rotate as easily as it should. The slip rings
still have to be installed also. The blades may be in need of a protective
coating to protect the wood from falling apart.

It should be interesting.

I've seen windmills which, instead of a rudder, had a smaller impeller
mounted just like the tail rotor of a chopper, except the big propellor is
pointing forward instead of up, of course. This small rotor was coupled to
a spur gear, that engaged a ring gear, such that when the small rotor
blew, it turned the spur gear to turn the assembly into the wind until the
rotor wasn't catching any wind any more.

I'd also seriously look into balancing it, and getting a thrust bearing.
Maybe wheel bearings from a railroad car...

Good Luck!

LOL, personal computers have been around longer than 25 years.

...depending on the definition.

I'd say the Apple and PET should qualify just as much as the first
PC
that IBM put out. At least they had graphics capability. And
everyone
knows that was the key factor to making the personal computer
popular
;-)

The IBM PC was the first to wear the label. ;-) ...and it did have
graphics capability. Again, depending on what your definition is.
;-)

I don't think you had pixel level control until Hercules came along and
fixed it.

Yeah, they did. It was called the CGA - Color Graphics Adapter. 320x200,
16 colors, or bitmapped text at 40x25.

Hercules certainly got in on the game, and I can't say if they beat IBM to
market with the color graphics, but I hadn't heard of them until well
after I had a CGA. ;-)

Hercules hardly beat the IBM. The CGA card shipped on the original
5150. I have one. Hercules claim to fame was the graphics card
driving the monochrome display.

What about the Copmmodore VIC-20? Peek and Poke to the graphics page

Hi Jim,

But a natural gas machine needs no gasoline station ;-)
Click to expand...
True, but so far I have only seen propane versions. These fell from
grace a bit when propane became more costly than gas per BTU. So I
haven't heard about these for at least a couple years now. Often the
conversion from propane to NG is simply done via fuel to air ratio
adjustments (new injectors etc.).

If your father's heating system is a real central heat furnace you need
something serious, like a big industrial strength UPS. These sometimes
show up for cheap at computer scrap dealers after mainframes were taken
down. It would have to be hard-wired in per code and probably needs to
generate 240V. On our central heat even the circulation fan runs 240V.
It is almost the size of an oil barrel.

Most of the things on the list were around before then.

Some (like the hybrid car) were around 100 years ago.

I think, in many cases, they are talking about particular
implementations of an old idea. In that respect, maybe it
should be a CMOS 555...

That is the link to the company's press release, yes? Does it say they
have a working cell, no? Is it 100% methanol, yes? The time has come to
look this technology in the face and except it for what it is, the real
McCoy.

Or stay in denial, like the people I know that won't upgrade from
Windoz 3.11.

You're looking at the wrong one of his creations. The MC4044P phase
Click to expand...
detector made for much better PLLs' compared to the limited lock
detectors used before (such as in the analog Signetics PLLs which
helped bring the concept to the masses and whic came out about
the same time). While I'm not so sure the rest is traceable to
the 4044, but you had a long period when PLLs were known but little
used due to complexity when using tubes, and then after the 4044
came along we had a blossoming of synthesized equipment. Everything
from two way radios, toss out those multi-crystal synthesizers, to
digitally tuned tv sets and radios.

The 4044 might not have been used in all those designs, it was too
bulky for a lot of mass produced equipment, I gather, from Jim's posts,
that the basic design appeared in other ICs. Certainly, Motorola
integrated it into various ICs that included more of the synthesizer.

And they were even used in disk controllers. I've taken apart some
early "IBM PC" boards, I can't remember if they were floppy or hard
drive controllers, and gotten some 4044's that way.
