Paul & Sabrina's cheap DIY 144v motor controller

nope, no foul language either.

'just a couple links to the agni creator. one was a link to dailymotion of an interview Cedric Lynch did on his footforward bike, and the other on their recent sucess at the TTXGP e-bike race.

Has any one received a kit yet? And what is the current lead time for a kit? Or are the FETs still playing hard to get?

I had issues getting a Synkro, so I have a Zilla 1K-LV on order but it wont be here for a while. I know it's over kill for a 96 volt Civic, but it's so nice (and expensive. )

I am looking to get a kit to build over my winter break (and maybe earlier if I ever earn back the costs of my Zilla). I have a scope and everything to build a kit, just need the time and my Winter break is a month long so I am going to need to do something EV related. (Hence the reason why a Zilla is on the way)

BETA TESTERS???

I was wondering why the beta testing isn't getting posted?
Everyone beta testing should be posting how the controller is doing,
How it is performing,
How many mile a day they are getting,
Total miles since install,
How the temp's are doing,
How the boards are holding up,
Is there any brown spots on the power board to show if mosfet's are getting to hot,
What kind of setup they have and what kind or performance they are getting,
What kind of cooling & temp with that kind of cooling,
What they like and don't like,
What they did to make it more efficient.
Beta testers should be posting regular updates on the controller, they should be taking notes everyday on all of these perimeters & posting.
I dont want this project to end with a thought of I got mine working you figure yours out!!!!

Hi Lou. I think Joe is the only one actually driving one right now. He's working on his A/C right now, so the car is in the garage. There will be more people driving them in a few days. I'm almost done with 3 controllers now. The JB weld on the nuts (loc-tite on steroids) is drying right as I speak. There are a few things to do, like make end caps. I'll probably just use the code that Joe likes in his car. It seems to be working well for him.

Lead time for controller kits is "10 weeks" but secretly, it should be shorter than that! I'm just saying that to make people not worry if it takes some time, since my job is starting up again in a few days. The kit is very diy. I've been taking lots of pictures, and I have a 26 page pdf that is evolving as the process improves and simplifies. The process is getting easier and better. It's still not what I would call easy, but it's very doable for someone that can solder.

Paul, you are a gift to us all!
I'm tempted to buy a kit just to puttz with it.
I really want to convert the 20 dollar Saturn some day.

[MPaulHolmes]

That explains why I like rapping! Because I'm a gift! I need to add all the pictures and then write stuff and stuff like that, and then post the pdf.

I have used a connector and individual wire connections between the controller board and power board Mosfet gates to equalise track lengths / propogation easily. Battery voltage monitor (thanks NiHaoMike) and rev counter are included. Spare inputs and outputs are also included.

Hello Mcudogs,

Just a general question is the firmware going to be updated on Wiki with the Battery voltage monitor and Rev Counter ?

As the updated Schematics are looking good.

Cheers
