Good question, and the honest answer is, I don't know. But I do know that the stars are far enough away from the housing to ever worry about heat or heat related issues. Also, how long will anyone EVER have the reverse light on for? 15 seconds, 30 seconds, 1 minute? The Z automatically shuts off the reverse lights after being on for 3 straight minutes I believe anyways. But, if it still needed, I can fabricate a heatsink for the luxeons for who ever thinks they need it. But honestly, I don't believe it's an issue.

I've got the basic sequence circuit board with LED made with using your diagram you posted, using SCR....
I'm not sure but SCR isn't functioning properly...

It's weird that some of the LED doesn't stay on, but some stays on...

I watched the video and I had the same problem with some of the first boards I made and tried. I'll try to explain this as simple as possible.

The 4017, the component that is outputing the 9 segments, only puts out around 5~6mA per output. For a good majority of SCR's, this is not enough trigger current to make the SCR trip, and stay on, resulting in them coming on, but not locking. I found the perfect SCR that always triggers and latches, but unfortunately I don't have the link with me. I am home for spring break and I didn't bring my computer with my saved emails. As soon as I get home on Sunday, I will post up a link to the SCR's. Nice job on the circuit.

I saw your list of parts, is that the SCR you chose?
This is one I got..

What is the use for 10uF?
Is the voltage regulator required? Car power source is not constant, but from 13v-14v they should run fine....

Sorry for all the questions..

where is the diagram you posted?

There is a new SCR that I picked up. I will post a link to it on Sunday when I get home. The 10uF cap is for another part of the circuit you need to add. Look under the 10 LED Sequential circuit at the next circuit. You need to incorporate the part that makes the counter always reset to output 0 when power is lost. And YES! The voltage regulator is required. If not, you will eventually fry the components and leds. If you keep on running the superflux leds at 13~14 volts for 4, you will eventually overdrive them, causing them to change color and burn out.

What would be a rough estimate of the price of the signals if you include the reverse lights also?

Id be intrested in this GB as well. Also would be nice to get the price on the reverse in the listing. Looking forward to hearing more in May. Subscribed.

I didn't post it...
It's in this thread somewhere...

Andrew, just when I think you could not get more creative with LEDs...you do! Excellent work!

Dooly

Any follow up??
I've been waiting for almost a week for you reply...

FOUND IT! I just got home from Spring Break. Sorry about the delay dooly. Here's the link to the correct SCR's.

To everyone else, prices and information will be posted on May 1st. That is when I plan on starting the group buy.

Soooo cool. This has to be one of the most creative mods yet. I'll be down for the group buy.

Andrew, are you planning on offering non-sequential LED install as well? i.e. A simple blinking LED cluster.

Acree

iTrader: (29)

Yup.

actually made a little board for myself... 21 5mm amber LEDs, and another board (for the reverse) w/ 21 18,000mcd 30deg white leds.. still not quite as bright as those Stars, but should be ok.. now the fun is going ot be getting the fixture open and not melting it/breaking it.. hehe.. yours look good, but i can't justify that much cash for lights

Nice. Congrats on trying your own project. Can't wait to see pics.

Just FYI - a tip on opening up the housings, I found it best to pre-heat the oven to 250 degrees, turn it off, then place the housing in the oven on top of wet cardboard. Let it sit for exactly 8 minutes. Pull the housing out, and it should come apart with a little pull. Good Luck.
