The above pic is 2 boards that will be separated and stacked after they are made. Made them all on one board for fabrication, it's easier to solder.
I would like to see more people trying out Lebowskis controller and helping him develop more features. The hard part about building a controller from scratch is you have to design EVERYTHING and it's a pretty daunting task. I believe with some simple kits we can get more people up and running on these controllers.
I have been working on a pretty small version of a Lebowski brain board for his latest chip version. The completed setup is 2 boards that stack with headers and is 3" long by 1.5" wide and I'm guessing about 0.75" thick. I incorporated my own error handling / detection system using a PIC 18F1320 if you so desire, it can also be bypassed by a jumper. The construction is a combination of SMD and through hole, but I made as many components SMD as possible. The board accepts the standard 40 pin DIP package he uses to allow for easy swapping of chips as he upgrades his code.
I have already designed and am using a larger version of this board, but this new one is about 1/5th the size of it. There are no current sensors on board for maximum flexibility and size.
If there is enough interest, I can have the PCBs pre fabricated with all the components and sockets for the chips which are flashed, but I don't know exactly how many people we would need to make this an affordable option since it would a low volume run. I know many are concerned about working with SMD components because I myself was until I tried about 6 months ago and not it's my preferred method of construction because I find it's easier than through hole in many cases, the opposite of what I expected!
Post up if you have interest. If we don't have much interest I can supply all the parts as a kit.
I'm also thinking about designing a small power stage for a complete controller setup that fits into a pretty small box. It would probably be 12 TO-247 100/150V MOSFETs and be good for 200A phase which is enough to make your bike pretty darn fun. You also get really cool features like variable regen!
