Lets see - you can use it as a brake light ... does that perk up your interest ...

Cool.

These were the 6,000 mcd yellow ones. Good for a night light.

Cool.

The light pool is relatively tight - due to my tight soldering - you leave a little leg for the led's and it works to direct it better. Soldering crooked works better too.
Also that last pic shows soldering on the back side. I twisted the legs and soldered them. Dont do that. Its better if you just contact and solder them. They can be moved around easier or even removed by desoldering. Twisting the legs = cant be removed easy without cutting it open.

I hope to show a haphazard job when the new ones I ordered come in.

But that little box and the 20 LED fitting is ideal for a kitchen under cab. That yellow 45 led set = night light. Its very ambient. You wont blind anyone, but you wont bump into furniture either.

Cool.
Srinath.

I made 6 of these using 1206 SMT LEDs glued to little wooden wafers.
I had to make a voltage regulator to kick the voltage down from 12 to 6volts.


This is from the first guy on the forum who attempted it.


HIS picture again, glued to a gauge cluster



To make the needles light up. They make LED bulbs that are a direct replacement for the bulbs in the gauge cluster but this cat used LED strings to get it extra bright.

Its surface mount device. Its those things that look flat, laying down per say.
In LED's they have a translucent look, not clear like a drop of water.
Cool.

Theres a lighting place that sells those SMD's in a strip. They put connectors on & hook the wires & charger up, ya stick em under the cabinet,, BUt, this idea looks like better lite & a lot less $$$ & I can surely solder. I have many soldering tools & I know how.  The "porcupine" effect seems easy enough to accomplish, just solder 'em in carelessly.. & with long leads left standing, fine needle nose pliers can tweak them this way & that to get an even spread on the light.

& I Stll thgink this otta either be in the Cafe or at least a thread in there telling people this is here. Lots of people avoid this area & this is not political,, YET! But you give me ONE , narrow little opening & Ill drag it there in a heartbeat!

The LED smd strip is not that bright. Its meant as accent light in your car. Its got a sticky back to it too.

Cool.
