Dropping 1V from a Regulated 6V Wall Wart

[Watson A.Name - Watt Sun, Dark Remover]

I read in alt.binaries.schematics.electronic that Watson A. Name - Watt
[email protected]>) about 'Dropping 1V from a Regulated 6V
Wall Wart', on Wed, 31 Dec 2003:


That's a coaxial connector, a bit like a phono plug but with a smaller
centre pin. Is that what you have?


I'd forget those descriptions if I were you. Certainly the Belling
connector has very little indeed to do with PAL. It is the subject of an
IEC standard - IEC 60169-2.

Yeah, but here in the U.S. you go to Rat Shack and buy a Euro or PAL
adapter, shove it in the socket, and forget about it for the rest of
the life of the equipment. Everything else is done with F connectors,
so it's not really an issue. In fact, I may heat up my big 100W
soldering iron and make the adapter a permanent part of the equipment.

alt-0233 = é with NumLock ON or OFF, Win2K machine

...Jim Thompson

On my Win2k machine Alt 130 is the é and Alt 233 is this ?. I use the é a
fair amount because it's in my gf's name.

I did this a while back. Replaced the 7806 in the wall wart with a 7805.
Wade

Yeah, but I've got four or five of them and I didn't want to crack
them open and then have to deal with the hassles of a case that's no
longer solidly sealed. And besides, they were only two bucks apiece.
I may bave paid more for their shipping.

Also, I bot four of the 6VDC unregulated wall warts at the same time,
and they have about 7 or 8V output unloaded. I don't think they have
enough voltage to allow a 7805 to work properly, at least not up to
200 mA, because the DC voltage drops down to near 6V at that current.

But 6VDC is a convenient value, used by a lot of equipment that has
four AA cells. So I have them just in case I want to 'electrify' one
of those ol' radios or whatever.

You can get low dropout regulators that will give you a stable 5v from a 6v
input, they're just less common.

AwwwRight! You gave me an excuse to use up those TIL430s that I've
got laying around. Awesome! Thank you!

é 130
T 233 <== I'm different here

as JW said earlier, there's a diff between typing and not typing
the leading zero and this is verified in the winders help.

different code pages

ß 0223
é 0233

that question mark you got is what happens when I try to paste on
in from character map.

Good thing we don't have to communicate with these characters.

It's easier to say

..... .- .--. .--. -.-- -. . .--

-.-- . .- .-. ... . -.. !!!

 

[Active8]

Don't type the leading zero unless it's a 2 digit code, ASCII codes are all
3 digit from 000 to 255.

I meant when you paste it (see char map, Windows Greek which I'm not
set for now that i think of it.) One more try though:

from http://www.jimprice.com/jim-asc.htm , link to "Decimal to Ascii
Chart".

it's 234

I didn't type the zero because it didn't say to

O 234
ê 0234
023 does nothing
{ 123
? 321
? 0321

If you gave a monkey a typewriter... (s)he'd probably type The Omega
Code on the first try

Try JB weld. It's been used on radiators, engine blocks, IIRC it
resists gasoline. I've used it for small auto body patches - it can
be filed, Shurformed, and sanded. Other epoxies would work just as
well.

And besides, they were only two bucks apiece.
I may bave paid more for their shipping.

LOL. You'll pay $5-$6 for the JB Weld at the hardware store.

The shipping kills me sometimes, though. Min S&H charge for a $2
item when you can place a $30 order for the same S&H.

Hmm. When I hit alt-0233, I get one of these: !

On what sort of machine, with what OS?

 

[John Woodgate]

We are talking about ALT0233, not ALT233. And on this machine with
Win98SE, ALT233 gives Ú. ALT 130 does give é.

What machine and OS are you using?

 

[John Woodgate]

I read in sci.electronics.design that James Sweet

Don't type the leading zero unless it's a 2 digit code, ASCII codes are all
3 digit from 000 to 255.

That ISN'T the way it works. ALT233 gives me Ú, while ALT0233 gives é.
YMMV, it appears, but at present we don't know under what circumstances.

We're workin' on it we're workin' on it

on alt 233, T, you and I differ, but not the é or ß

I'm set for English(United States) - Regional and Language settings
in control panel. I'm sure it does us no good to ask about OS
without also asking about the locale settings. When we say machine,
I think keyboard might be the more pertinent question. Maybe
there's some oddball scan codes or something. I'm using a
Microsloth Natural Pro without the especial software for the surfer
dude etc keys, but it would appear XP took care of that. They all
work.

Oops, - ßßß - You're right.

Also, measure your connector & see if that MX 75 O [ <== this
little omega looks like a zero. arrrggghhh! No HTML in NNTP
either.]

connector I posted the OD on is close. And if you look back to the
link I posted on these extended ascii codes and other useful (?)
links, you'll see a connector reference link near the top.

I finally found the adapter at Rat Shack. http://tinyurl.com/2784r

$3.99? That's for a hundred?

I could make one out of an F panel socket and a Belling-type line socket
for GBP 0.63 at one-off prices from Rapid Electronics in UK

Oh, I suppose at the current exchange rate, that about $4. (;-)

CPC (a Farnell company) has all four permutations of socket/plug for
prices from GBP 0.69 to GBP 1.36 at one-off prices. But delivery is not
free.

Yeah, well I went over to the battery display when I was in Rat Shack
the other day. They wanted $3 someting for four AA cells, and I can
go over to Fry's (any time, not just 'on sale') and buy four alkaline
AA cells in a blister pack for a buck and a half, less than half RS's
price. Go figure.

So if the adapter was sold by some other electronics store here in
the U.S., it might be only two bucks instead of four. But then that's
how Radio Scrap got a store on every corner, and is known colloquially
as the McDonalds of electronics.

But then someone showed me a URL to Dick Smith Electronics in Oz,
which had this adapter. If I had bought one or two from them, they
would've cost more when considering shipping, etc, and would've taken
a couple weeks to get here. So looking at it from that angle, four
bucks ain't half bad. ;-)

Yeah. That's the only reason I go to RS. Damn! I forgot to order...

Watson- Perhaps I missed it but did anyone suggest a Schottky Diode in
series with a regular Silicon Diode to add up to a one volt drop?
There seems to be a wide selection of Schottkys available.
Can't remember how much current you required.

Cheers, John Stewart

Yeah, I suggested it along with the original schem I posted which was
the same as the bias transistor often used in the power amp totem pole
output stage. The 400 ohm pot looked best when set to 280 ohms B to E
and 120 ohms B to C.

Many excellent alternatives. Thank you to all who replied.
