We had an 'Afro Engineer' at the AFRTS TV station in Alaska.
Anything he touched turned to crap, and the only thing he was good at
was drinking his month's pay in under a week.
I've improvised & made parts that weren't available. That includes a
TV tuner for a piece of broadcast equipment. The only tools I had were
a few hand tools and a soldering iron.
It really hit the fan when someone told one of the Army cooks that
they were renaming the mess hall to 'Ptomaine Hall'. ;-)
(UTC) typed in rec.crafts.metalworking the following:
Jerry had to improvise even when they were winning the war. They
had this problem that the demand for material (trucks, tanks, guns,
etc) meant they couldn't take a captured factory off-line to retool to
a standard "type". Plus they had a lot of captured items (tanks,
transports, etc) that they pressed into service because it worked.
Imagine having to keep parts on hand for trucks made in Germany,
France, Czechoslovakia, Russia and England/The US?
It is a wonder they lasted as long as they did.

When I was a kid and my parents had company, I tended to sit with the
men. One, especially, who was born 1904 in Norway, whose mother
operated a lighthouse there...had the best stories. He could make the
telling of cleaning a fish highly interesting. He lived a long life and
he and his wife were the best friends a person could hope for...they had
a special gift for making one feel special when with them, would do
anything they could for a friend but sure didn't suffer fools. They
could be gutting and remodeling their home, which they did several
times, and yet have company for dinner and not have a spec of dust
anywhere. In later years, both had severe health issues but did
together what neither could do alone.
I discovered in the early days of working in nursing homes that old
folks had awesome stories and rarely were unappreciative of the care I
gave....those who were unappreciative needed more :o)
Me and JH do work on telecom, network and other low voltage systems for
a chain of nursing homes and we were in one a two hour drive away last
Wednesday and Thursday. We were both in a lot of pain and I couldn't
climb up in the attic to pull wire so I was down in the hall handling
the 10 foot ladder going from access hatch to access hatch. I was having
some chest pains the first day and of course every joint was hurting so
bad I had 90 year olds in walkers come up to me and ask if I was OK. Me
and JH have been looking for a young sober guy about 50 years old to
help us pull wire. ^_^
LOL! You are correct! I just bought a 900W microwave from Walmart
[made in China] for around $46. I have not had to clean the buttons
yet, because ...yes, the plastic coating has deteriorated and looks
like I ran a soldering iron over them.At first, I thought this was a
protective plastic sheet that I had neglected to remove and was
supposed to be removed. Guess not.
That's the type that doesn't notice the damage till it's too late.
Hell, a GOOD US made membrane switch would sell for more than $30 in
quantities of 5,000 or less.
Being who I am, I am replacing the switches in a wireless mouse. I
can't find another model that doesn't bother my Carpal Tunnel, and
Logitech has used the same switches for over a decade. Not that I think
most people could replace one on a double sided, board with PTH.

Which reminds me...I picked up a microwave last week from a Scratch
and dent store for $20. Kenmore product, current model. I fired it
up before buying it and it worked well. Got it home..fired it up..and
it ran for about 30 seconds and then it puffed out some smoke and
So I popped it open and found a thermostat secured to the top of the
cooking chamber that had literally melted down. Bypassed it..and it
works fine. I suspect its a safety that senses if the chamber gets too
hot because of fire or other extreme temperature. Simple open/close
device that had for some reason..melted. Wires were fine, plastic on
the connectors was not melted and there were black smoke smudges on
the inside of the cover. No idea of why it melted down. Must have been
something internal..not well made. Near the klystron and above the
lightbulb compartment. Main power runs through it. So I put the thing
back in operation with wire strippers and a wire nut... and in
fact..cooked dinner in it tonight. Works fine.
So I took the old Panasonic that had failed..and Id replaced with the
new Kenmore out and opened it up too. Filled with spider webs, the
odd fly, roach and lots and lots of crumbs. Probably 12 or more years
old. And virtually identical to the Kenmore internally. The only
difference was the position of several of the internal sensors and the
electronic display for the various cooking programs. Cleaned it out,
sprayed the circuits with board cleaner to get the crumbs and roach
turds off the board, , let it dry out, fired it back up and it now
works just fine as well.
I was rather amazed at the simularity between the Panasonic guts, some
12 or more years old..and the new Kenmore guts. Obviously Sears doesnt
make their own nukes and is buying them from Panasonic. Shrug
We finally lost our Microwave tank we bought in 1980 or 81.
We bought a new model - about the same capability - less in some way
more others - but this one I could pick up and hold in one hand.
They changed the heavy core transformer - 1 KW is a transformer!
To a switcher supply - aka modern.
When we turned it on, it swamped or killed WiFi in the house. Never
tried the cell phone but computers would not be on line...
I now have hard wire to those computers and we can use the microwave
It is a Panasonic. Works just fine - suspect the osc in the switcher
is just there.
You could try a power line filter, I have small ones I use on telecom
equipment but I'm sure you can get a high current filter for appliance
use something like what's in the links below. ^_^
Some reviews of the Logitech M570 trackball say it helps their CTS:
(Amazon.com product link shortened)
I bought one to control 7 Media Center from the arm of a chair and am
slowly approaching the precision I acquired with a mouse from 20+
years of CAD work. At first it was very awkward.
My hand is slightly too small for it and slides back unless I position
it where the chair back supports my elbow.
It does take a little while to get used to a trackball, but Ive been
using them for at least a decade and they are very good.
Be sure to change the settings in Windows (or whatever OS ) so the
ball moves properly for your "touch". Its all changable of course and
can be adjusted nicely
How long have you had that M570?
Now that I have asked, ;~) I am going to tell you how to fix it when it
quits working properly. I am on my 3rd in 2 years, Logitech has
replaced 2 units without requesting a return.
My problem has been with the center click button, this center click is a
big time saver in Sketchup for orbiting while panning. Anyway I could
hear and feel the click but the orbit command would not engage unless I
pressed even harder after hearing the click and then some times having
to hold down the wheel and wiggle it. The cursor would not go from a
pointer arrow to an orbit icon. A real PIA.
After getting the second replacement I decided to open up the one with
the problem. Both had the same problem BTW.
There are "5" screws on the bottom and inside that have to be removed
to open the unit. One screw is obvious just under the ball on the
bottom. 3 more screws are under the rubber pads opposite the ball and
at the far long ends. The 5th screw is under the battery label at the
1.5v lettering. Poke a hole through the diagram label at that point to
find the screw. Then pull the bottom half away from the top half.
Inside you have a small square switch with a round button, flood that
switch with electrical cleaner and or any other switches that may be
giving you trouble. Thoroughly blow dry the assembly, I used compressed
air and reassembled. Works like new again.
I have tried several trackballs, and none felt right. They were much
harder for me to position the cursor accurately than with a decent
mouse. It might be OK for newsgroups & Email with more practice but
they were useless for Eagle (Circuit board layout) ot LTSpice (Circuit
simulation) Forget doing graphics with GIMP or another graphics
