Re: LED's

[Austin R. Baer]

Seems to me that a single, heftier voltage regulator that provides a fixed voltage source in the 6-10 volt range could be a useful package for under dash mounting, set up to provide constant voltage for modules of a specified number of series-connected LED's at each one of a dozen terminals on the box . If the voltage is clamped to 7.8 volts, for example (to drive half a dozen LED's @ 1.3 volts each in series), the LED's could simply be used in bundled packages of six (or whatever, for appropriate ratings) wired in parallel (perhaps two bundles for each brakelight, one for each taillight, etc.). We ought to be able to avoid individual fixed voltage sources for each location on the car, as well as the jumble of resistors, and simplify maintenance in the bargain.

There's got to be someone on the list with regulator or zener diode technology in his resume who can design a box for the rest of us to build so that we can treat grouped LED's like so many Lego blocks. How may T-ABC listers does it take to replace a taillight? All of us.

OK, Technogeeks, I have the answer.....we can install a PDU (power distribution unit) from a modern aircraft, use the special built-in voltage source controllers along with a couple of inverters (standby and main) to power any accessories that need ac power, a computerized CWP (central warning panel) to monitor everything and lastly, install a JATO unit for passing in a hurry! Or we can order the bulbs with the controller built in, and put it into the socket, and drive away! Best, Ray McCrary "Speed is Life; of course Luck and Altitude are helpful, too."

I can't wait for another endless thread on sensible, simple, cheap and durable LED's, discardable by any purists down the road, but which can keep a red warning light glowing brightly on the back of a tiny car that: a) has little capacity for generating enough current to light its own way out of the dark, and b) which can vibrate the filament off a subway bulb, but c) has a battery big enough to keep LED hazard lights blinking for three years after it's run out of gas.

When someone has a circuit design for a regulated LED power source that should fit in a 35 mm film can and cost $4.00 to build, please mark the subject line accordingly. I have confidence that the posting will take no more than two days to appear. And yes, Ray, I am trying to make the world safe for technogeeks!

No problems so far on five English vibro-mobiles!

When someone has a circuit design for a regulated LED power source that should fit in a 35 mm film can and cost $4.00 to build, please mark the subject line accordingly. When the bulbs are available for 4 bucks, I will cheer, too! I have confidence that the posting will take no more than two days to appear. Right! And yes, Ray, I am trying to make the world safe for technogeeks! Technogeek is not neccessarily a bad word..... Yahoooooooooooooooooooooooooooooooo! I am now going driving in the M....with LED taillight....! Best, Ray

Hi Ray and other T-Typers! Your answer was very funny, but doesn t cover the problem. The problem is: Tooooo dark lights at the beautiful backside of our cars (specifically at modern, fast traffic). Someone use a fog-lamp as a third brake light. We all know how they are looking at a bright-coloured car. In interest of (passive)safety, one resolution are LED s. I fitted one self-made lamp nearly invisible behind the spare-wheel carrier. Now I have no more fear, that a very close following car overlook my brake signals! For the interested T-Typer: Today, I took some pictures. Hope I can present them next week Please ask for details. lozi (TC3762)

Look what happened to the last guy that mixed JATO and automobiles: The Arizona (USA) Highway Patrol came upon a pile of smoldering metal embedded in the side of a cliff rising above the road at the crest of a curve. Wreckage resembled that at an airplane crash, but it was a car--make and model unidentifiable at the scene. A lab figured out the story. It seems the driver had somehow gotten hold of a JATO unit (Jet Assisted Take Off--actually a solid fuel rocket) that's used to give heavy military transport planes an extra "push" taking off from short airfields.

He drove his Chevy Impala out into the desert and found a long, straight stretch of road. Then he attached the JATO unit to his car, jumped in, got up some speed and fired off the jet device. The cops calculate that the driver of the car...hit JATO ignition at a distance of about 3 miles from the crash site. Ashphalt was scorched and melted there.

Reaching maximum thrust within 5 seconds, causing the Chevy to reach speeds well in excess of 350 mph and continuing at full power for an additional 20-25 seconds, the driver, soon to be pilot, most likely would have experienced G-forces usually reserved for dog fighting F-14 jocks under full afterburners, basically causing him to become insignificant for the rest of the event.

The individual remained on the highway for about 2.5 miles (15-20 seconds) before the driver applied and completely melted the brakes, blowing the tires and leaving thick rubber marks on the road surface.

Became airborne for an additional 1.4 miles, impacting the cliff face at a height of 125 feet and leaving a black crater three feet deep in the rock. Most of the driver's remains were not recoverable; however, small fragments of bone, teeth and hair were extracted from the crater and fingernail shards were removed from a piece of debris believed to be a portion of the steering wheel.
