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.
Bigtoy, contact tterev3 Kids a damn genius! Easy to work with. Also I think Hoop could help with the MCPBs based on what he is doing for quad XP packages. That machined quad idea of his I think could be adopted very well to your project. Also you could toss this Idea into the Oshpark thread, there are a lot of very capable scary smart folks in that thread. With all of you working together I’m sure something amazing could be produced.
On a similar note, I just purchased a 2015 Tundra. The fog lights are wimpy. That cylindrical host you made, I think with an aspheric lens and an MTG2 would be an amazing flood light and more simple to design. If shortened and made to fit in the fog light housing of the Tundra it would be awesome and without rival.
How much would you charge to build blank housings without the horizontal cooling fins. Something like 6-7inch long and no individual led slots, just the front bezel to put lexan lense?
Edit: I wish I could learn to work metal like that.
I have officially gave up on the small triple. Couldn’t find a engineer to make it work. I have a new little project i’m working on now that uses 2 XHP50’s using 45mm LLC49 optics. Trying to make a small bright offroad motorcyle light. 40 watts and 4750 lumens should do the trick. My other bar is a bit too big for bikes.
Any electronics guys want to help redesign my current driver to work for the XHP’s? I was thinking standalone on a fr4 board and no micro for now. Just a simple 3A buck. I have all the schematics. The driver works well in my big light just not on the small MCPCB board.
I have a few of the Russian drivers on the way to play with.
