Think of mAh as if it were the breaking strength of a rope in pounds.
You want to lift a load that weighs 500 pounds.

The instructions say that the rope should be rated at 600 pounds.

So know let's rephrase your question.

Is a rope that is rated at 800 pounds ok to use?

For starters, are you saying the wall-wart reduced 120V AC down to
0.5V with a current of 2 amperes, DC?

From: whit3rd

If you get a Peltier cooler, and heat one side while applying
a flow of air to a heatsink on the other side, it will put out low
DC voltage at high-ish current. Into the right kind of load.
So, that'll work from any battery that can heat a resistor and
maybe run a coolling fan.

Well, you DID say 'any thoughts'.

Seriously, do you have any accuracy requirements? AC or DC?
Any preference on battery type (palletload of lead/acid, or
single hearing aid cell)? Duty cycle? Battery life under load?

If you have access to a 'scope *and* can get to the legs of the receiver
module, you may try probing it to see what kind of output you get. The
ones I've seen have power, ground, and an open collector output that may
or may not have an internal pull-up.

Thanks. Both remotes show up in the viewfinder, with a round
blueish-red pulsing light when any button is pressed.

FWIW, it was the original remote, that only works with this one
device. But except for 2 numbers received once, neither remote has
any effect.

Are you distingishing the IR receiver from the rest of its circuit?

The factory remote doesn't support any other device. (Even though
it's only a 4 year old design, based on a 7 year old original design.)

Thanks again.

Yes. The front end (IR detector, amplifier, BPF, wave shaping)
circuit is usually integrated into something like this:
<http://www.radioshack.com/product/index.jsp?productId=2049727>
<http://www.google.com/search?q=ir+receiver+module&tbm=isch>
I don't know what's inside the DVDR3576H but it will probably be
something similar. You should be able to connect an oscilloscope to
the output, and see pulses generated by the remote. You can also take
an IR receiver module, and turn it into an IR remote tester. Build up
a circuit to supply power and connect to the output to a scope.

However, it still might NOT be the remote, since you can see the IR
with a digital camera. I question whether it's the IR detector module
since you claim:
"Used the universal remote that doesn't have all the
commands, only on/off, numbers, play, stop, etc. No better."
Since the DVDR3576H works with the universal remote, it can't be the
IR receiver. You have a partial contradiction here, which makes
little sense.

One remote possiblity is that the remote has drifted in frequency
sufficiently to make it unreliable. You would still see the output on
the digital camera, but since it's off frequency, it won't control the
DVR. Can the original remote operate any OTHER device besides the
DVR? You did mention that the universal remote was able to control
other devices, so I'll declare that one working.

"No better" than the factory remote worked. That is, it didn't work.
Sorry.

I don't know why I specified what commands the thing had when it
worked.

The universal does work fine with a TV that it is also set up for.
Maybe that's what misled you.

>One remote possiblity is that the remote has drifted in frequency
>sufficiently to make it unreliable.

It was working fine until it wasnt' working at all, except for those 2
singles-digit numbers in the middle of loads of unsuccssful testing.
Where I held the button down for a long time, though I've done that
too plenty of times without getting anything. Maybe I should hit the
thing. :)

No. Only designed for this one thing.

:) Okay, but not for the DVDR.

Ok. Then the problem is in the DVR and probably the IR receiver
module. Drag out the oscilloscope and dive in. There's probably a
test point near the IR receiver module, or just check the leads for
data. This should be easy (famous last assumptions).

Note the switch and the 0.047uF cap in the AC line to the amp - this is
the " polarity switch" and it connects the chassis to one or other side of
the AC supply via the cap. Users are meant to select the less noisy
position, which equates to the neutral conductor.

To duplicate this set up , the isolation stepdown tranny must have one side
of its secondary linked to the supply ground.

The only thing left " un-American " then is the frequency of 50Hz - which
WILL cause the power tranny to get rather hot.

Speaking of bullshit:

... and the whores you rode in on.

You know all of this because you personally designed or reviewed/approved
every fuckin piece of audio-related equipment that any idiot may attempt to
attach to an amp.


Well, it seems you haven't.. or you might have a GD clue.. many PROPER
isolation transformers DO have a side to ground thru a high-value resistor.

Wow.. a transformer that generates heat? You complete dumbass.
Overheat - NO.

Use all the space you need to list all the electrical devices that DON'T
generate heat.

Returning to plan A. What I think of as a lawnmower connector, 2 part outer
shell. Just space to mould in the existing US plug and fix in a third pin.
All demountable leaving the original cable and plug untouched, if so
required. Then either black nylon spiral wrap or heatshrink over the green
wire along the original cable. Satisfying the original brief but would be a
lot cheaper for him just having 2 core cable replaced with 3 core and 3 pin
plug, retained in the cab for any , unlikely, future USA based user.

Why not copy the dos HD to a new disk?
Just make sure that you format it with format /u/s d:
so that the mbr and bootfiles are on it.

Oh and put a reasonable primary partition(<32gb) on it with fdisk first,
and delare it to be bootable.

It appears not. I posted something two days ago and I still don't see
it. In fact I haven't seen any new posts either. Lenny

A lot of people are complaing about Google groups not updating
properly for the last week. There are other free or low cost news
servers availible. news:alt.free.newsservers is a newgroup that
discusses these servers.

Use http://groups.google.com/group/alt.free.newsservers/topics for
Google groups users.

I recently switched to Eternal September

Seems to be working just dandy.

Most of us never notice this anyway. Because of the low signal to noise ratio
(even for UseNet) we have all GoogleGroups postings go directly to the trash.

Has anyone here tried this? I'd like to find some information on how
to do it, schematics, etc. They all seem to be proprietary and I can't
find any documentation. Ideally, I'd like to interface the wheelchair
to something like an iPad.

This patent application includes a detailed controller schematic.

There may be others.

Start with either the various robotics forums, or controller interface
forums:
<http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?board=hardware>
<http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1265918811>
<http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1229539904/all>
etc... Search for "wheelchair".
