    Has anyone built a HW melty brain or in fact anyone with a FW in the U.K. that works? I'm going to buy the kit to have a play around and see what RPM it can function at, I think some of the IMU mem devices are even better now. Also the brushless rotax 50cc and bog standard controllers suit the uni-directional constraints

    I believe Team Nuts use melty brain tech in Nuts 2, so you might want to ask them.

    I experimented using the open source melty brain website to make a featherweight a while back. I got it to the stage of being able to move around but university exams took over and I didn't have time to fine tune the logic on the test platform before installing it in a chassis.

    Yep - we have used Melty brain in Nuts 2

    Its not straightforward. We have a custom speed controller board from Rory with a Melty brain logic board and software from Gareth

    This is the test rig


    and nuts itself

    That looks good, like the transition from 2wd to melty as well.

    Are you also running the Orangutan B-328 and ADXL193?

    We looked at open melt but decided it wasn't really suitable for what we needed, so we made a custom PCB with all the required parts on one board, and Gareth wrote all the code from scratch.
