I wonder if they would work right on a metal. The metal
would perhaps shield them from some directions, be a
ground plane for the signals needed (at a bad distance?)
and consume the signals in resistive losses. Also probably
be within 1/2 wavelength or so .... signals would see mass of
metal but not RFID tag ...

A friend of mine is looking for a 5K watt transformer or higher for some
project he is working on not sure exactly what it deals with. Does anyone
know where I can find one for cheap or free? He lives in Hilo, Hawaii.

Post more on the required parameters, and you might get an answer.

5,000 watts is going to be uncommon.

Hi there Dana,

I see we need to separate USB DATA from USB POWER.

All GPS Owners Manuals & all the reviews I found seem to be clear on USB
data transfer, and some seem to be somewhat clear on USB charging, but none
seem to be clear on USB operation!

I suggest future modern portable electronics reviewers ask basic questions:
a. Does the portable unit CHARGE using standard (5v/500ma) mini-USB?
b. Does the portable unit OPERATE using standard mini-USB?
c. Does the portable unit transfer DATA using standard mini-USB?

We'd all benefit from the answers. There is no downside to having this
critical information for all portable electronic devices in the future.

My goal is a single AC + DC + PC suppy & cable for my cellphone, mp3
player, earbud, camera, and handheld GPS! I won't buy anything that's not
standard USB for charging, operation, and data!

Sarah, It seems you will not buy anything needing more than 500 mA which
includes a lot of devices including just about any of the devices with
backlighted color screens and hard drivers. Someday perhaps power
requirements will be lower but for now you will only be able to buy very
simple units.

Hi there Dale,

I understand what you're saying. But let's remember our Blackberry
"mini-usb" charger outputs 750ma c.c. so I think the "practical" upper
limit at least 50% higher than the "official" USB 2.0 spec already.

I've had no problems charging my blackberry from the PC, from the AC, or
from the DC adapters.

Still, don't you think these three yes/no questions are of use to users in
a GPS review?

a. Does the GPS CHARGE via mini-USB connector?
b. Does the GPS OPERATE off the mini-USB power?
c. Does the GPS transfer DATA through the mini-USB port?

If necessary, one could construct a USB cable which connects the 5v and

going into mass storage mode.

Hi Terran,

THIS IS A GREAT MOD!

If removing the 'data' pin from the mini-USB cable works to tell the GPS
it's POWER and not DATA, that's fantastic! It would all of a sudden make
the Garmin nuvi units usable for my purposes!

Being a herd animal, I wonder aloud ...

Has anyone ever done the USB-data-to-Power-only mod successfully
for GPS units such as the Garmin Nuvi's?

sarah
PS THis is what the usenet is all about! This is a GREAT idea!

The USB specifications require that USB ports or host controllers and
powered hubs have in built current limiting to ensure that the port (and
the host / hub) are not damaged by devices connected to the port
attempting to draw too much current.

No damage will occur to hardware that adheres to the specifications no
matter what load is connected to the power supply from the port.

This is great news. It's probably why our Blackberrys work just fine even
though their AC + DC mini-USB adapters put out 750ma.

Not for the users, certainly.

Hm. Sounds like the perfect solution would be a powered hub, modified
with a switch for each socket that you could use to switch off the
data lines & the 5V current limiter.

The questions are ok, but may not be as valuable as you think. For
example a GPS might charge via the USB connector when hooked to a pc and
still not charge when hooked to a separate 12 Volt adapter. (This is the
case for iPods for example) It may also charge so slowly that it is not
useful or charge but only when the unit is off.

Is there any digital to analog converter that would have a minimum

No.

You would need to buy a USB scope and PC software.

The alternative is getting into microcontrollers, USB and PC software.
