6 Xm-l light bar build

JESUS H CHRIST!! :bigsmile: That thing looks like a 4wd projectile clawing its way up the rock field. Your cooling fans werent even running at the end of the run. If you ever mount a forward camera to give us the drivers perspective, please post it here… that is if your bobbling head doesn’t knock it off of its mount first. :wink:

Thanks for the names. Im probably going to make the pilgrimage to Tommy Wongs in Vancouver for the tune.

I like it. :slight_smile:

wow, you weren’t kidding when you said rock crawler were you?

This project is currently on hold right now. I am looking for a new Electrical engineer right now. If there are any reading this and want to help, please PM me.

Oh no… what happened?

If you dont mind powering several light bars with a single driver, you might want to give DIWdiver a shout and ask for his advice. Check this thread for driver details.

Who knows, maybe he could design a complete driver for you if the existing version doesnt work out. Or maybe modify your existing one. Let us know how it progresses.

Two failed prototypes and no response from my current engineer.

Unfortunately a off the shelf driver will not work. It needs to be designed to my specs.

Reading through, I see that PTK was involved. I hope he’s alright. Do you have/own the files for the boards and have parts list, or is that the intellectual property of PTK? If you have them, then perhaps they could be modified by another. Id still contact DIW and see what he might be able to do for you. If anything else, he might be able to suggest someone who can assist. Failing that, Id start another thread here and on CPF with your driver request and provide a link back to this thread to show your product and support.

Good luck.

I am not going to go into detail on the forum.

For the motor heads
Video from yesterday!

Thanks for posting… someone’s having waaaay to much fun! :bigsmile:

Two engineers and 4 prototypes later I still do not have a working board. I am not sure what I am going to do at this point.

Bugger , Im happy to wait I would like 2 of those triples but with nw emitters.

I looked at the top brands eg baja designs/rigid , and your lights are easily comparable but ur better on price.
Being a small business owner myself I would prefer to buy from the little guys.

Trev

Have you tried Mattaus here? No idea if he can help you or not, but he does lots of board designs round these parts.

I havent reread the thread so apologies if you have.

Back to the drawing board. The second engineer decided to give up. I’m not even sure at this point if it is even doable. Small single layer board and high frequency= to much noise. |(

Any engineers here think they can help?

Why design your own board when there are ones available that might work?
Not sure how difficult it would be to get it to go from 3.3v to 3.8v to get the proper VF for 6P xmls though

It has to be custom to fit my housing and do what I want. Nothing off the shelf will work.

Id like to see you get through this and resume your builds. Try http://www.aeroleds.com/ in Boise. Their company size just might be small enough to piece out some engineering work. Their LED landing & signal lights are a big hit amongst several aircraft owners I know personally, and Ive spoken with them a few times over the phone… nice folks. Good luck.

Fair to say, not just on an FR4 board, but on a mcpcb with led’s to boot :O. Just in case anyone thinks they have ideas.

Cereal_killer is a whiz at designing stuff…throw him a holler too

wight, TexasPyro, anyone from the OSHPark forums…those guys are all geniuses!

There is a way to basically turn a mcpcb into a “2 layer board” buy using “Sinkpads” to solder directly to the mcpcb creating a ground plane. Just need someone to experiment with it. The production boards will be Sinkpad II.
