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.
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.
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?
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.
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?
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.
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.
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.
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.
