True Adam.. But the blocks are not "hot" (er in the sense of connected to any side of the power) are they? I can't remember his name BUT he did die ( of over excitement ) from PLAYING a gaming computer LOL !

You have water- cooled your controller right ( I have been lurking)

I have not water cooled my controller yet, but have designed the block needed to water cool it.

I am currently working on rebuilding my little milling machine to allow me more opportunity of milling PCB's and the water blocks. Once its back together, I have a 2 parts that I need to make for my father-in-laws car, then I plan to mill a water block for the current controller.

If somebody is willing to try it out, I would Love to see how it does.

Nice! Are you going to use a small pump and , say, an oil cooler radiator with fan to disperse the heat away?

I'm sure people will jump at the chance to try it !

Hi All,

It would be greatly appreciated if the ReVolt Wiki could be updated as the open source Controller, BMS, Charger project files become available. Thanks !!!

I ran across this website Development and Prototype boards and tools for PIC AVR and MSP430 for an AVR-CANbus controller. They have a lot of nice AVR header and development controller PCB’s. The AVR-CAN development PCB uses a Microchip MCP2551 CANbus controller and a handful of discrete parts.

The CANbus interface to the AVR looks simple enough http://www.olimex.com/dev/images/AVR-CAN-sch.gif, I don’t know how complicated the changes to the Cougar firmware would be? But since Paul is using the CANbus on his new BMS and Charger it would be nice to have a version of the Non-Synchronous Cougar Controller that had a CANbus interface too.

A question that I have to the forum is: would the firmware for the Cougar Controller be compatible with, or could it be ported over to a larger AVR controller (AT90CAN128)? More memory, more I/O, etc….. I also like the idea of using a Daughter Microcontroller PCB. Having a standard ReVolt control board you could swap or upgrade the Daughter Microcontroller PCB with different Micro’s AVR, PIC, etc… of course it would need the different firmware too.

Comments ???

Paul could i ask you to do a few mods to the "special" code again? Would you be able to increase the on delay to 10 secs and set it up so it cant energise during precharge?

I can try to post the schematics and parts list-inductor designs. I don't know the first thing about computors. It's open-source. I think it should have it's own thread-is there one now for us? Can someone open one? I also designed a speed control for the A/C compressor motor, and the 90 (?) amp erzatz alternator.

Post it here. I would like to see it.
Thanks

I'm going to TRY to post the 8 pages. There are rweally 3 inductors on one page-OK for me but to make it more clear, there are 4 inductors to make L1, and one has an extra few turns, then L2 is on the same page. 7 out of 8 pages are over the size limit. What do I do?

One solution would be to host the pictures or pdf. files in a web server service, like photobucket.com, no pun intended, and include a shortcut link in any thread for people to see them.
I will contact you soon fellow LIander.
