Thanks
what size is that in metric ?
I would there is a builder wire to suite
( lousy and hungrys will have it)

Umn, bit of a guestimate here. look at Dick Smiths Guage vs MM site

But around 0.4 to 0.5 mm

Oh , I know you can but 1mm or .9 mm single strand builders wire but

your ask seems a bit thin
must it be plastic coated or would enameled suffice ?

Not sure, suppose enamelled would do. Would have to try it. Dont think
it will matter fo my uses. Main thing is single wire, but twin lead.

** The stuff you are after is known as in the trade as " bell wire ".

Seems to be readily available everywhere except in Australia.

Try a big hardware store or other place that sells door bells and
accessories.

Commonly called Twin Twist Bell Wire, one red and one white wire, single

strand core.
Often used as the lead-in wire between the shot-firing box (exploder) and
electric detonators used in a blast if the lead-in wire is not too long.
Can be purchased from most wholesale electrical suppliers. Srr the following

** Nope.

Bell wire is a flat, "figure 8" style cable.

Used to carry the low voltage AC supply for domestic door bells.

Normally just plain white to blend into the wall or skirting boards.

I agree with Phil. I used bell wire in the 70s when playing around with

door
bells etc.

I am using Analog Device 5B38-02 as a strain gauge amplifer, however, the
gain is pretty low, which is around 160 and it can't be adjust.

Is there any method to increase the gain to 300?

****Why bother asking the question as you have already given us the
answer,"it can't be adjust(ed)"?

Here is a link to Dyno Nobel in Australia where they give a very limited
description of what is commonly termed Twin Twist Bell Wire in the
explosives industry.
http://www.dynonobel.com/dynonobelcom/en/asiapacific/products/accessoires/

I have purchased this wire from various electrical wholesalers over the
years. Below is a pdf link for an Ausie supplier.
http://www.hartland.com.au/hartland/pdf/01-catalog.pdf

I note the original poster stated he had tried L&H. I have purchased this
cable from L&H also in the past. Their P/N for the product is PIR5414387. Go
to the hagemeyer web site and do a search on the P/N and it will pull it up.

Here is another link to this cable at the Prysmian (Pirelli) web site.
http://www.prysmian.com/en_42/cables_systems/telecom/product_solutions/communications_copper_cables.jhtml?s1=25800007&s2=25800011&s3=4300004&s4=-1
Go right to the bottom of the page.
To be noted with this product from the various manufacturers that there is a
considerable difference in the tensile strength of the products for the same
wire diameter.

This wire is/was predominately used in the telephone industry and has
nothing to do with doorbells.

The OP is after " TWIN LEAD WIRE" !!

He is not after *blasting* cable.

Wrong stuff, wrong topic.


.......... Phil
I am sorry Phil, you are wrong. The blasting industry uses this product

because it is available and suits a purpose. Review the available literature
on this cable and you will see that it is quite possibly what he is after.

As I state in another post, this cable has nothing to do with doorbells but
a lot to do with the telephone industry in past years and the use of bells.

yup...the gain is can't be adjusted.

i may add another precision amplifer to increase the gain.

 

[smd led lamp]

Agree of that.

that sounds like the stuff in CAT5 cables, but I'm guessing you want
figure-8 instead of twisted pair.

"doorbell wire" last time I saw that stuff in DSE it was way expensive.
tried Rexel?

If you were desperate enough you could strip open a CAT5 cable. They
have 4 seperate twisted pairs of 24AWG solid bare copper. Different
colours to boot.

Two pair telephone cable might suffice , very very cheap as well.

Hi to my pals here,

In October 2005 I bought myself a DSE G7659 STB.

It worked like a charm for 17 months or so. Then, it began to misbehave just
as the Commonwealth Games was being broadcast from Melbourne - first just
a few pixellations, cracking noises and the odd audio muting. This soon
became much worse and affected all digital channels.

It *had* to be the STB and it was exhibiting the same symptoms reported by
others on usenet.

Once on the bench and open, I probed the various rails coming from the
MPS - a separate module on its own PCB.

The 5 volt rail showed a bit more HF noise than I expected but all voltages
were OK. I left it powered off overnight ( no AC supply) and the next day
the symptoms were drastic, ie no pic at all !

This time the 5 volt rail measured only 3.4 volts with even more HF noise
than before - I reckoned that would stop the processor in its tracks all
right.

With the aid of my trusty Bob Parker ESR meter, it was soon clear that both
the 1000uF, 10 volt electros ( Asiacon brand) on the 5 volt rail had gone
high ESR - to about 1.5 ohms each !

New ones tested only 12 milliohms and were soon installed and that fixed the
5 volt rail very nicely and returned the unit to full operation.

The PROBLEM with the G7659 SMPS is that all the electros are tucked under
an L shaped heatsink that runs hot - circa 75 C even with the box in free
air.

My Thomson DTI500AU STB runs *damn hot* too, esp on the botton side,
too hot to touch the metal base plate. Always been worried about it,
but it does only get switched on when I'm using it, so I can at least
sleep well at night :->

The easiest, permanent fix is to install a 40 mm, 12 volt, 0.6 watt fan
blowing onto the heatsink. The wiring loom from the SMPS to the main PCB can
be easily broken into to access the +12 volt rail and 0 volts.

The full 12 volts not necessary fro the fan and as little as 8.5 volts does
the trick as far as cooling the heatsink is concerned. This involves fitting
a series resistor of about 100 ohms and an electro across the fan of
220uF - without the electro the fan may not start on power up.

Does the fan noise cause a problem?
Those things can be really distracting.

In article <ivnYf.10681$JZ1.414926@news.xtra.co.nz>, ken@home.nz says...

Spread spectrum or frequency hopping may be used on either or both so
little chance they can be fully separated, suggest send polite but
firmly worded letter to both manufacturers and see what happens,
oh and CC the distributors and Choice magazine, cheers

No point sending any letters as it is not a protected band.

Well certainly not to the ACA or any other communications authority,
but raising the issue with the manufacturers could offer a work around
and provides feedback etc There is value in that paradigm, I've used
it before and there shouldnt be any resistance to pursuing it etc.

If it has a bakelite handle it will probably date from 1950 - 60's. I

Does the fan noise cause a problem?

** No.

At 1 metre from my unit, the fan's noise is inaudible.
