Frankly, I don't know when I'll get this done, since even a small spool of
magnet wire at Frys is $ 25, and I have a limited number of $ 25 chunks to

small discretionary fund.
Have you though of recycling wire? Smallish motors are not rebuilt like
larger ones and can be bought for scrap prices.

Hi William,
Good to hear from you. Actually, no, I hadn't thought of that. That's
an interesting link.
I might have to pursue something like that. I have a fairly large coil
of wire that I bought long ago that's something like 28 AWG. I could
use it to wind smaller individual spools of wire but I haven't decided
if I want to keep it as is or not. I might want to do some experiments
with a large coil. Of course, winding spools of wire is a challenge in
and of itself. I might have to put the spool on an old record player
and turn the thing on to spin it around.
TV's are interesting animals. My Dad learned the hard way a long time
ago that the flyback transformer can knock you across the room with an
electric shock about an hour after the TV is turned off. Also, if you
crack the picture tube, you can get a nasty implosion. But, it is
interesting to think of harvesting the wire from them, and people
certainly are disposing of them. I wonder if I can buy a TV at Goodwill
cheaper than I can buy the wire that's in one.
At this point, I've aquired a Raspberry Pi B+, power supply (5v 2a), usb
power cord, hdmi cable, and memory card. I'm supplying keyboard, mouse,
and wifi adapter that I already had. I also bought a couple of how to
bookazines. I'm into it about $ 120, and for now, I have to save up a
while before buying more. For the moment, I'm going to focus on
learning how the Pi works, and how the GPIO pins work, and how to attach
sensors, buffers, and drivers. I'm also going to work on learning some
GO or Ruby programming with the device. While the recommended beginner
languages for the device are Python and Scratch, I think I would like
the others better based on my reading about their features. Hopefully,
I'll actually get to the point where I can drive some coils.
Sincerely,
Ron
