Subject: [alt-beam] Re: Tricore info question
speaking of weird arrays of microcores, following my creation of the
pentacore, are there any faults with using a layout like this, mine
has three running motors, and the other two acting like a bicore
head, using photo resistors to adjust the length og the pulse and
make it turn towards the light.
Dennisons hextiles sure look nice, how about a description? I could
proberly work it out eventually but if someones sure about it why
bother.
