Hey guys,

Seems like thyratrons have become quite rare these days and SCRs or GTOs
are just too freaking slow. Is there a readily available alternative
that doesn't cost an arm and a leg, meaning under $100? A kilovolt would
be nice and >50A.

A thyratron is a switch as I recall. How about two
or three cascaded FETs ? The circuit is called Marx
stack I believe and achieves few ns out of ordinary
FETs by avalanching them. 50 Amps are hefty though.

93LC56A Description
The Microchip Technology Inc. 93XX56A/B/C devices are 2K bit low
voltage serial Electrically Erasable PROMs (EEPROM). Word-selectable
devices such as the 93AA56C, 93LC56C or 93C56C are dependent upon
external logic levels driving the ORG pin to set word size. For
dedicated 8-bit communication, the 93AA56A, 93LC56A or 93C56A devices
are available, while the 93AA56B, 93LC56B and 93C56B devices provide
dedicated 16-bit communication. Advanced CMOS technology makes these
devices ideal for low power, nonvolatile memory applications. The
entire 93XX Series is available in standard packages including 8-lead
PDIP and SOIC, and advanced packaging including 8-lead MSOP, 6-lead
SOT-23, and 8-lead TSSOP. Pb-free (Pure Matte Sn) finish is also
available.

There are lots of them, and each time one wears out that's just more new
stuff for a system to verify. That's the problem with veryfying sources. I
think it's best to assume innocence at first, no matter what, to be sure
that most people can publish quickly.

I agree the software could be updated to check sources better, but it can't
do anything with virgin data, there's nothing to compare with. That's where
the user spam flag idea comes in. That's how the system best learns what is

Can anyone please identify the green NiMH cell? Can anyone suggest a source
for a replacement? We are in the UK.

the only way to tell is to take a sample and strip it down. some rg-6 is
copper covered steel, some is solid copper.

Is the center conductor of the el-cheapo RG-6 found in home
improvement stores always copperweld? It seems to be 18AWG copperweld
but maybe I'm being naive...

Is this part of the RG-6 mil-spec, or just the way they make it today?

We need to find a replacement transformer for an old unit. The
original has a dead short between primary and secondary. As best as I
can tell, the transformer is marked Vernon Co., V_6021, Pri:135VAC Sec:
25VAC. It feeds into a full wave rectifier into a DC motor, no
capacitors. The motor draws 24V at 12.2A, per the mfg dataplate. Any
ideas for a replacement transformer? Line frequency is 400Hz, but
60Hz transformer will be just fine.

Thanks,
Steve

Forgery. Since TURD persists, and is in the US, I'm going to make an
example out of him.

Go for it; you're not the only person who'd love to see some of these suckers

I'm thinking a good rule for nFilter might be, "add to the WHITELIST anyone

The word "goddamned" has NEVER been hyphenated, you stupid twit.

Thanks for replying !!

I searched the net for days, and the only one so far that I've found
is BigTrack. The ball is big enough for those who have frail hands,
and for those whose hands keep shaking uncontrollably.

I'm glad that BigTrack works for your uncle.

Again, thanks for replying !!!

Hi, all !

I am setting up a computer lab for the disabled. We are looking for
equipments that might aid the disabled (mainly those who are not that
good in movement), and one of the things we are planning to get them
is trackball.

There are many types of trackballs available, unfortunately most are
made for the able-body people. I am looking for something that can be
used by the disabled with ease.

Our objective is that the trackball must be big enough, and easy
enough to be used.

One of the things we have found is the BIGTRACK trackball made by
infogrip (www.infogrip.com/product_view.asp?RecordNumber=98)

I want to know if there are other types of trackball similar or better
than the BIGTRACK that I list above?

If you have any experience on which type of trackball that will be
easy for the disabled, please share with us.

Thank you all in advance !!

I purchased one of the BIGtrack trackballs for a 70 year old relative who
has limited dexterity in his hands due to an industrial accident.

He tends to loose his temper while playing computer card games and gets a
little ruff with things, not that anyone could ever get him to quit playing
the games. He never used a computer until he was 65 and has become quite
addicted to the games available to him.

Prior to purchasing the BIGtrack trackball he had either worn out or broken
three other trackballs. The Kensington trackball lasted the longest before
suffering a fatal break in one of the roller guide supports. He was always
complaining that even when the other trackballs worked he had a hard time
keeping the pointer where he wanted it.

It has been 6 months with the BIGtrack unit and he has not complained once
about controlling the pointer. He has commented that he liked the larger
sized trackball that the unit provided. It has withstood his somewhat
physical temper tantrums with no breakdowns, so far.

There is one thing about the BIGtrack trackball that takes a little getting
used to. The mouse buttons are on the top of the trackball, away from the
person rolling the ball. I thought the button placement to be a little odd
at first but it does help in reducing most accidental button triggering by a
random hand or arm movement.

For those who have even more severe limitations I suggest getting the
BIGtrack unit that supports external buttons. That way you can place the
buttons anywhere convenient for the user independent of the trackball. Be
they foot activated or strapped to the arm of a wheel chair.

I have a fairly odd need here.
Basically, I would like to extend the RAM of a PIC18F from 4KB to around
20KB so that I can create some sortof framebuffer for a 130x130 lcd
screen. Being simple chips, PICs can't address external RAM like, say,
an 8051 can. I would like to keep the pincount down as _low_ as
possible, with speed less of a priority. I was just wandering: is there
such thing on the market as an SPI SRAM?

If so is there anywhere that will supply to the UK in small volumes -
5? I've scoured the usual part suppliers - Farnell, Maplin, RS, Arrow
and can't find any.

If not I guess I'll just use another PIC as an SRAM controller set up as
an SPI slave.

Brendan Gillatt

Or you could go straight to an ARM-based chip which has the RAM in it.
There are some from NXP with 32 and 64kB, though I have not used them.
Farnell has a special offer on the non-RoHS version of the 32kB one
(7342640), under ÂŁ5. I have been trying the ADuC7020 series myself, but
those have only 8kB SRAM I think.

Which is why I stated its primary purpose as being that of isolation

What exactly needs isolating from what ? Have you noticed they tend to be
made of plastic ?

The transformers are made of plastic???

** Don't be such a pompous bloody prick.

Of course he meant the phone itself.

A telephone loop has both VF (voice frequency) and DC
signals going in both directions, all of which need to
be "isolated" from each other.

** Don't be such a pompous bloody prick !!

Any "isolation " transformer has " galvanic isolation" .

Look it up on Google, if you are still completely clueless.

Wot a Wanker.

Hi, all out there...
I'm have just bought an broken FLUKE 8600A bench-multimeter.
When I power it up, just one digit or all 4 digitpoints lit up. And a
relay is buzziring.
I'll checked the voltage inside the unit.
I found that the +15/-15 volts was very low. About +8 and -1.6 volts.
I pull out the big IC, U8, and there I have my voltage back as they
should be.

So I strongly beleave that the 40-pin IC is bad.
It's labeld : MPS7107 and dated 7505.
In a schematic I got for the instrument, it say "Custom CMOS DVM
chip", so it's not a standard component.
Is there someone out there have such a IC in there junk-box, and want
to sell it to me?
Pls send me an email if You got it.

With the very best regards from SWEDEN

Merry Christmas to all of You!!!

First check all the electrolytic capacitors in the supply,
i have had a 8600A that also behavies very odd and a relay was buzzing
and the only failure was a defective elyt.
Even the low voltage reading you mentioned speaks therefore,
you are measuring a median value of the "pulsating DC"...
