DVD Rewinder

[jurb...@gmail.com]

Got in a pack of new clip leads. I can do alot of things with clip leads. They are a bench staple like the ends off of components, paper clips, various glues and potions.

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.

[et...@whidbey.com]

DVD rewinders are rare. Write only memory is rare too, but not rare
enough. I have come across write only memory DVDs and that's what I
use my DVD rewinder for.

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?

WOM is not that rare - the 25120 was designed by Signetics engineer John
G 'Jack' Curtis back in the early 70s and included in their catalog:

Anti-static bags don't work. I put one of my radio designs inside
such a bag and all I heard out of the speaker was the same old static.

I like the DVD rewinder, but can't you just insert the CD upside-down
and play it again to rewind it?

You really need anti-static bags for protecting clip leads.
Atmospheric electricity increases at the rate of about 30 volts/ft[1].
If you're 6ft tall, there should be 180 volts between your head and
your toes. If you bridge this voltage with one of your new clip
leads, it will surely create a spark. With the typical low quality of
Chinese clip leads, that would probably blow the wire as if it were a
fuse.

I think that voids the warranty on Sonys and a couple of other brands.

I can insert a DVD upside down in my laptop to write the label.

You actually got that "Lightscribe" thing
to work?? Stuck a disk in my tower,
configured the label the way I wanted
it, hit "OK", waited a half a friggin HOUR,
no status on the screen, no sounds from
the CD/DVD disc DRIVE, eject - blank label.
Never bothered with it again.

Not at all, actually. Just buy a cheap USB memory stick from Ebay.
Fill it up with data and then try to read it back. You will notice
that most of its rated capacity is write-only.

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?

Some types of anti static bag defeat the security tag detectors in shop
doorways.

The motivation behind making them so readily available is anyone's guess.

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 ?

Many things I buy from Farnell now comes in anti static bags, regardless of
the vulnerability of such goods to static.

I suspect the cost of this packaging is less than the cost of the litigation
of not providing goods in this packaging, and then having to deal with
spurious/bogus claims of static damage.

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.

Alligator and crocodile clips are useless in todays miniature
electronics. The best I can do are "wire hook" ends like these:

When you write "affect"/"effect" I take it you mean altering the

Perhaps someone should invent caiman clips. Ideally they would be sold

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

a bed of nails test fixture, positioned with the flex plastic hose

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

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.

[John Robertson]

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.

Not me. I tried it a few times and gave up. It takes forever,

No thanks. An inkjet CD printer works better.
