By alot do you mean not a lot the way atheist means not a theist.

Yesterday I had to go through a metal detector to get into the court
house. Even had to remove my belt so the buckle would not set it off.

Got me to thinking that iron and steel effect radio tuned circuits one
way and brass and maybe some other materials affect it the other way.

Could someone have say a knife with a steel blade and an matching amount
of brass go through the detector with out setting it off ?




By all means try it, we are all in for a belly laugh.

OK, fairly nice set of leads.

THEY CAME IN AN ANTI STATIC BAG !

I want to call that company and ask if they have any DVD rewinders in stock.

I'm forever stepping on the ones that fall off the bench unnoticed, and they flatten almost completely (and I'm not overweight). Years ago, clip leads were heavy stamped steel or copper and much more durable. If you ever run across a source for these let me know.

How fast is the DVD rewinder?

Here are 100 of the small alligator clips with red insulators for
$13. You can repair the damaged ones, or make your own.

They have others at reasonable prices, as well.

Seems to be some smart people here. I need to learn how to empty the /dev/

I have lots of scripts that that write to it and I suspect it needs
emptied.

Any help?

mv /dev/null /dev/null ... that should do it!

Alligator and crocodile clips are useless in todays miniature

Sure. Merely change /dev/null from a device node to an ordinary file
with 666 permissions. The file will grow and grow until your disk
fills up. Overflow indicates that it's time to clean out the
accumulated junk with a simple:

/dev/null
and start over. No need to have root permission, anyone can do it.

With this method, you have the satisfaction of knowing that /dev/null
is working, not having a dangerous black hole in the middle of your
system, and giving the NSA a chance to look at what you are trying to
hide in /dev/null. If you get tired of clearing the /dev/null file,
you can build a FIFO buffer (i.e. named pipe) where /dev/null is
maintained at a fixed size, and new junk tossed into /dev/null will
push old junk out the other end of the pipe. I'm not a very good
programmist, but I'm sure it can be done by someone more evil and
devious than me.

When you write "affect"/"effect" I take it you mean altering the
resonance. It would be foolish to measure only resonance without also
measuring Q, which would certainly be altered by metals.

To effect radio tuned circuits is to cause them to exist.

If you recall the movie "The Graduate" there is just one word from the
cocktail party scene that answers your point.

I don't know if your scheme would work but I do know that airport
metal detectors have some way to discriminate between a key in my
wallet and all the titanium and stainless steel in my arms, back, and
pelvis. I used to set the things off but not any more. I have spoken
with folks who have long pins in their legs, artificial knees, and
artificial hips and they don't set off the airport metal detectors
either.

Yuck. Hook clips work fine until one gets to boards full of SMT
components. I have a box of spring loaded probe tips, originally from
a bed of nails test fixture, positioned with the flex plastic hose
used for coolant hose and camera tripods. The board is secured to a
PCB holder and spring pressure makes the connection. Much better and
easier than tack soldering wires.

I'll be at home for a while longer so no photos but here are the
components:

Insulation Displacement Something. Yep, been there with every ribbon
cable connector. I even have the proper IDS compression tools for
most of the connectors used in PC's.

Wire Wrap. Yep, I still have my spools of #30 wire, which I now use
for soldering breadboards. I still have my manual tools as I sold my
battery operated wire wrap gun.

Now, are you familiar with my policy of ignoring one line questions?
The problem is that one line questions usually lack any content,
value, understand, detail, and are generally not worth reading. Since
your nom de plume implies uncertainty, I'll make an exception this
time.

I'd enjoy seeing pictures of your test bench setup with those pogo pins.
Near as I can figure you use those semi-stiff hoses to hold the pins on
the UUT (unit under test). For me, not su useful as I am mostly fixing
TTL stuff (not many folks still do that), but I can see it being very
useful on SMT products.

No thanks. An inkjet CD printer works better.
