Very nice looking bkt. Whats the possibility of it moving around in an arc with the single cap screw either side of the light? Gotta love cable ties. Wink
I am not picturing what you are trying to explain. Example?

It needs a third bolt in a slotted hole, to lock the adjustment down instead of relying solely on the two pivot bolts.

Oh, gotcha. I can’t do that on this light, plus I think it looks like crap. Other light bar manufacturers do that. I think it will be just fine on this light. My big light is like this and it does not move. I can always rough up the back side of the bracket for more bite.

I wouldn’t have thought it a big problem, I’ve never had tilt adjustable lights move unless I happened to land on them and then their angle was the least of my worries Smile

Great piece of machining, they look awesome!

Nice light, I have seen rock crawlers in the past on TV but nobody around here has had one until recently. In the past 3 months I met a man that had one, a new coworker has one, and a recently past coworker’s long time boyfriend builds them full time for a living. These things must be exploding in popularity. And the cost of a good one is super expensive, like 6 figures. With people putting that kind of money in them, $190 is pocket change.

Nice looking bracket.

I’m wondering something about the light housing and the bar housing. Why did you choose to make the fins go around the light, both this one and the bar, across the flow of air instead of with the flow of air? Seems if the fins ran longitudinally they would be more efficient at dispersing heat.

Think he made these on a lathe, no way to cut fins the other way.

The MG-T2 light is build on a lathe, no way to make the fins the other way on a lathe.

For manufacturing reasons. They cool just fine.

Don’t think the bar was lathe made, had to use a mill for those. Which would also do the lengthwise groove for air to flow down instead of over. Just wondering is all.

Edit: No offense, but easier instead of better.

The bar was done on my mill. Same thing. It is much easier to machine them that way.

24 emitters driven at 3A each… very well done! :bigsmile: It looks like you have quite an impressive crawler to play with. Do you have a link to a spec sheet?

You missed the six in front.

The low mode should be lower.

WOW! That looks like a tank powered by a turbo LS1. You have amazing fab talents… and perseverance. How does it run? After playing with LSx engines over the past decade, they seem to do a lot of things really well. Is there a good chassis dyno shop in your area that specializes in LSx tune? Im due for a retune after several mods on my vette, but there’s no one in my area up to the task of getting the most out of it.

Even your jack stands are amazing.

Buggy runs amazing! Mine runs on Megasquirt 3 running E85. I do all the tuning myself.

The shop I dynod at(Garage 808) can do LSx stuff. He mainly does Honda stuff though. I am sure there are shops in Portland that are good also. Maybe Horsepowerfreaks?

Video of A race I just did.

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.

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.

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.

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?
