Dear All,

I have two HP 1630D logic analyzers, but neither of them has a
flexible disc drive, is it the 912D/S?

9122 is one of them.

Is it the only way for me to
get inverse assembler file?

Yes, most likely. You have to be able to download on the 488 bus,
since that's the only way you can talk to the machine. The 1630D will
talk to the disk drive directly, or can be controlled with a computer.

I couldn't disassemble without this disc
drive. Could the HP 1630D logic analyzer disassembler for 8031
microprocessor ?

Yes, it can, it will label each of the instructions for you, but that
has to be set up from the computer. You can set it up from the logic
analyzer, but you will lose the setups when you turn off the machine.

I would very appreciate any information and experiences with this.

Thanks ans Regards

So where's the "OT:" in the subject line?

You think a subject like that needs an OT, so you can
figure out it's not about an electronic circuit design?

The purpose of OT in the subject line is so that one can
filter out all OT posts without having to look at each
thread and figure out whether the subject is off-topic.

The problem is that the topic sometimes drifts back into
electronic-related discussions but the participant fail
to delete the OT when it does.

Fair enough. I'll take that as a green light for me to start my own

Promiscuous sex is the common wisdom, especially by traveling

education. Have at it. Just label it properly and keep the

It is. The trouble is that the Usenet FAQ is at www.nowhere.nohow.zz, I

I own a Tek 465. I am the "Nth" owner of this unit.
I purchased it from a rebuild/calibration lab.

It operates ok but the display becomes erratic when the CRT intensity is turned up to the extremely bright level (the 3 o'clock position), I think it is arcing internally causing the tube to "spit". For most of the work i do, the intensity level is set at a level where the spits do not occur (about 10 o'clock).

Is this an indication of a tube ready to die?

Thanks in advance.

LED flashlights seem to be getting more popular these days. There
are
numerous websites that sell them, of different types and sizes.

But here in New York City, I have yet to find a retail store that
sells them.

Wal-Mart, Target, any camping store should carry them.
They're easy to find here in nowhere indiana..

The one I like, is usually at knife stores, the Inova X-5
White, Red, Green, Blue, or UV wavelengths available.

The problem with Inova is they use a much more expensive lithium
battery.

What's bothering me is that very few flashlight makers have
progressed
to designing their lights to use rechargeable cells. If more AA cell
sized flashlights would be designed to use Ni-MH cells, the world
would
have a lot less batteries to trash, recycle, etc.

And a lot more dead flashlights sitting in drawers, cars, and other
places. Sure, if they get a lot of use, rechargable batteries are
nice, but they'll self-discharge to uselessness in a month or two. I
dunno how many flashlights I've got, but if I had to worry about
keeping their batteries charged I'd end up doing nothing else...

I don't know about you, but it doesn't seem to be a problem for the
several cordless phones, cell phones and cordless tools I have. They
come with a cradle to put them in when not in use. Another way is like
the ones we have at work: there is a fold-out plug on the side of the
flashlight and it stays plugged into the wall when not in use.

This isn't rocket science, you know. The cost or a rechargeable
cordless phone, screwdriver or whatever might be in the $20 to $30
range, less on sale. The leap from a 900 MHz full duplex transceiver to
a simple light beam is a leap backwards in technology.

I've been running white LEDs at 50 to 60 mA, and I'm finding them
dying
in a matter of days to weeks. The 20 mA that they are rated for is
okay, but 30 mA is iffy and and above that will start to overheat
them,
and they lose their long lifetime.

How would you reduce the current of the power source to make it
compatible
with the rated current of the LED?
After all, the standard formula for the desired resistance is ...

R = (V8 - Vf)/If

R = the resistor
V8 = dc supply voltage
Vf = rated forward voltage of the LED
If = rated forward current of the LED at specified forward voltage

Notice that nowhere in the formula is the current of the power source.
So if the voltage of the source is already equal to the rated voltage
of the LED, how would you reduce the current?

That last paragraph, above, has got me bumfuzzled. I'm not sure what
you mean.

Well, you wouldn't, but in the real world it's never that simple.
First, the "voltage" of the LED isn't a specific value, it's a range
of values depending on manufacturing tolerances, temperature, and
phase of the moon. Likewise, the voltage of your power source isn't
exactly <so many> volts, it's a battery with a nominal voltage, which
in the real world will start out high and end up low.

Many tiny flashlights don't use a dropping resistor at all, they just
depend on the internal resistance of the battery to limit the current
to one that will not burn out the LED immediately, though it may show
some degredation in light output over time.

There are lots of solutions, from higher voltages and current limiting
resistors to complex switching buck/boost converters. You pretty much
get what you pay for.

I pay less than $2 per cell on Ebay.

Most people don't shop on Ebay, they buy their batteries at the grocery
store or worse yet, Radio Scrap. And they're _not_ cheap there!

Wylbur may not understand that the supply current and the LED current
are identical...
