I need to terminate two 50 amp cables in a large terminal strip. There is
one line of thinking that if the cables are soldered before terminating,
over time the solder 'gives' making a possible loose connection.
I have no option to using a terminal strip.

We can supply parts and load PCB for you! Our company is located in
Melbourne and
the PCB will be loaded overseas. We are qualified supplier of PCB
Assembly of many multi-million companies in Australia. However, we

Fundamental questions.
Given:
If I wire two 3V 1mA batteries in parallel, the result is 3V 2mA.
If I wire two 3V 1mA batteries in series, the result is 6V 1mA.

I have a 4x8 trailer hooked to my Honda Odyssey. They are connected to
each other using a 4 pin connector. The problem I'm having is when the
van lights are "on" then the trailer lights will not work at all.
However, when the van lights are "off" the trailer lights will work.

I'm after a cheap small run PCB assembly house, that can do small SMD
board assembly, either in Australia or overseas.
Nothing too fancy, small individual boards (not panelised), double
sided load, 0805's, QFP, couple of through hole parts and other SMD's,

Hallo listers,
We have a problem: Our church build in 1300's has a Carillon (  Bells, Glockenspiel) of 16
bells that used to play every hour on the hour  a hymn for three minutes.
Every bell has an solenoid actuator that strikes the bell; this mechanical component

I have a 32" JVC tv model # AV-32f702...I have a few thin white lines
at the very top of my set and a series of dashes below it. I have been

I have just bought some Sgi F180 flat panel displays
at auction and they are missing the video cables.
The specs refer to it as a
"15 pin D-sub connector / DVA connector"

I need some MMC cards for a device that cannot handle cards bigger than
128MB. I've looked on eBay and there are one or two suppliers. The
prices are reasonable ($US7 each), but the postage seems a bit excessive
$US15.95 + $4.50 per card.

Hi everybody. I know that exists now a device called PVR (Portable
Video Recorder) and I know that a lot of you know that device; well, I
know that there are from  flash or sd memory based (relatively
cheaper) to hard disk based (in general expensive), both come with a

I'm after a new HD Set Top Box, and would like some recommendations.
My main criteria are that it switches on fast, changes channels fast,
and has a HDMI output. Low operating and standby power is nice too.
I have another HD STB (DigiCrystal) that takes forever to switch on,

I have various devices that have exposed pins or holes for pins. I'd
like to examine the states of these pins/holes by connecting wires
between them and a solderless breadboard. Typical examples include
pins on MIDI ports, D15 game ports, D25 printer ports, etc. If I get

G'Day all.
I'm trying to locate some 10k slide potentiometers. DS, Jaycar, altronics
don't sell them anymore.
Farnell sells them for about $7-00 each. (Is that the going rate, or can I

I have a Tevion model TDR250HD DVDR which I purchased about a year
ago. At that time I noticed some strange things about the input
impedances on several video inputs. I posted my observations in
sci.electronics.repair but received no suggestions. I've since

Four days ago I posted a brand new throw-away e-mail address here so
that people could contact me about the EA magazines.
   So far tonight, two nice spammers have sent congratulations to that
address, telling me I've won not one but two lotteries!
