Has anyone come up with a logo design? I have a process I want to test and if it works decently I will make it available for the Re-Volt controller.

xtian - i'd recommend a decent sized finned heatsink on the bottom of the controller if you hadn't already planned on one. when you mention perforating the mounting board, i assume that you aren't (since a heatsink would cover the holes anyway).

my heatsink is just a bit larger than the controller base and has 3 high volume computer fans on it. I have a thermal sensor in the heatsink that touches the base of the controller - it reads about 12-15C above ambient temp when continuously pushing 200 amps on the highway. In the AZ summer heat, this setup has never allowed the controller to go into thermal cutback mode while accelerating with high amp draws.

regarding a fan for the controller internals, we previously determined that it wasn't necessary. The primary heat source are the switching components and their primary heat dissipation path is through the heatspreader to the base of the controller and heatsink. Circulating air through the controller wouldn't hurt, but the additional cooling surface area would likely be small compared to a finned heatsink.

The RTD explorer does show the thermistor temperature - if you install a fan for the internals, it should be easy to quantify its effectiveness.

By the way, I'm working on the layout for a synchronous rectification controller right now. I'm using PCB artist, which is free, but pretty easy to use.
haha, i'll be sure to use a proper topic in the subject line!

i'm lookin forward to the release of this high power SR controller!

I did some work on a logo a while back. The discussion in that part of the thread starts at:
http://ecomodder.com/forum/showthrea...tml#post113749

For anyone who is only reading from this end of the thread, here they are:


Everyone has my open permission to use any version of this logo to print out and make any sort of sign, sticker, etc. to go on their controller, car, or window. Just be sure to credit this project and point anyone who asks back here!

If anyone knows somebody who works at a sign shop, it would be great to get a sheet of these printed out and mailed to Paul! Any new controller kits could come with a sticker!
