Actually I found one of these at a secondhand shop for $40 and I

bought the new 15v battery it needed (from battery world) and it was
over $10 IIRC and I found that jaycar leads with a bit of a trim
fitted in quite well. Your price seems pretty good considering I had
to disassemble and clean old battey gunk from the contacts and the
insides. Apparently they have been made sinse the 1920's. Actually I
was expecting a rats nest inside but mine is mid '70's, printed
circuit. Probably not as collectable as the old ones but works none
the less. I did a bit of a check on the net and they still make them
but the price is.. well damned expensive. I even found a circuit for
it on the net. Mine didn't have the leather case. Do you have one, a
leather case to sell separately? How about original test leads.

I remember being told about power resistors used in series with high power DC
motors (kW) to give speed control. The resistor was used to control conveyor
speed at an underground mine. The resistor was made up of two metal plates
which could be immersed in a water tank to different depth, hence giving
different resistance. What's the propper name for these. Can anyone point me
to any links?

thanks.

I also have an older MAC could be 512 or 1Mg one I do not think it has
a h/drive ..comes with a bigger yellower keyboard(the original ones)

yes their prices are cheap .. but even though there is lots of them ..in
not too distant future they will be real collectors items ..purely for
their small size and suvivability ..not many of the original PC's are in
the same boat ..many are dismembered or junked because they were ugly,
big ... and lets face not worth collecting..many leak battery acid over
the mobo and are stuffed ..

The MACs would be good to star in furure movies ... like they do now in
"Back to the future II" ... cute! or one of the star trek movies "
return home I think ...one with the whales ..)
You can still always use them as a dumb RS232 terminal..you could even
interface a PIC chip to them ..now there is a thought!

I thought maybe you could have a sine wave generator at 50hz feed into an

I suspect the o/p's vision was for something MUCH smaller, and vehicle atteries
don't fit most ppl's toolbox.

A simple oscillator + driver transistor pumping a step-up transformer should do
the job - no rocket science. After all, the application is really a go/nogo
situation, to indicate that the multimeter ain't dead. Actual output voltage
and frequency are far from critical.

Would Sine wave be all that important just to be sure the

No. If he wants to see if it's reading accurately at the same time, I

[gearloose]

hi john,

if you're only going to test a meter then u probably don't need a
300watt inverter (stepped sine wave output) or even a small UPS like u
use for your computer.
But a small stable audio oscillator with a known output voltage, like
a dick smith kit, and then use a small power transformer to step the
voltage up to 240.
so, if the audio ascillator has an output of 5v @ 50hz, then use a
240v~5v trnasformer to step up to 240v at low current.
it's rough, small and cheap - i assume u don't need a calibrated unit.
