And you guys call *me* a troll?

I have PCBs with 30 LEDs and limit resistors on it. Powered by a 12V
6W dongle.

I posted a hi res pic of them on flickr.

You connected LEDs and resistors?

36 LEDs and 12 resistors.

12 sets at one dongle per set of two sticks. That's only 3 Watts each
stick. Unless the dongles lie or are being overtaxed.

I am quite sure I could put more than two sticks on a single dongle,
but I didn't want to sit down and configure an LVDC distribution panel.
They work fine in pairs, and the power strip is a 'panel' for the
dongles. Same juice ends up getting used either way, though there are
likely a bit more losses on the many dongles method. Making fewer dongle
fight harder is probably a slight bit more efficient. (splitting it on
the DC side).

He was bipolar and off his medication, like several posters on this
newsgroup. He screwed up when he phoned the local sheriff's office with
some false information, and threatened a church I was working with to
collect computer equipment for Veterans who couldn't afford a system.
The first ISP had been assured by the local police department that he
was harmless, along with the second. The third was a national ISP who
didn't check. After he went silent, I found that he had moved back to
his parent's house. He had quite a police blotter. The police had to
remove him from a Red Robin restaurant, he was banned from shopping at
Wal-Mart, and had the police called when he tried to run a woman down in
the parking lot of her apartment complex. There were a lot more, but
those are the only ones I can remember right now.

I complained to Roadrunner abuse dept. about one of their users, and I
included the offender's full message headers because I knew they'd need
that.

They wrote back requesting that I send them the message headers,
so I replied and included them again.

Then Roadrunner wrote back again, telling me that I needed to supply
them the message headers ...
I replied, reminding them that I'd been including the headers every
time, and here they are once again.

And Roadrunner wrote back again, telling me that I needed to supply them
the message headers ...
My last email told them that I was through wasting my time with them.

They probably looked at your posting history and said, "Screw it!"

LT Spice shows 0.64 amps at 1.236 volts. Most diode data sheets show

Mine are not the dumb versions. The switch, and control circuit is in
the tail. That means that it takes the 4.5 volts in and correctly
controls the feed to a single, super-bright LED with 3 distinct modes.

It is so well designed that when your batteries begin to avalanche,
the second mode no longer functions precisely as designed, signaling
the operator to use the first mode or third mode, but to also prepare to
replace or recharge your cells. The 'nose' end of the battery pack gets
applied directly to the LED. The circuit and equivalent limit resistance
presented to the virtual series circuit and LED and power source resides
in the tail of the lamp and is electronic. Bike riders use similar LED
drivers units in headlights that flash (tail lights too).

I know more about LED flashlights and bike lights than a "see if there
are any resistors" dope like you ever will.

Driver to drive?
