a two sensor, two motor brick that would be
approximately 4X6 studs on top, and about two bricks high. We were just
wondering if anyone out there thinks something like this would even be
possible.

The pcb for my Brainibot kit is around that size. (Just search the web for
"Brainibot".) It uses an 8-pin PIC and has two H-bridge motor drivers, two
"antennae" (e.g. push switches), a light sensor and a sounder. One of the
models is programmable from a PC; another is programmable by "typing" on
the antennae; a third just runs a standard program.

The Brainibot pcb uses through-hole components and is 1"x2". A surface
mounted version would be very much smaller of course. You'd need 4xAA cells
in another box.

I wouldn't recommend using a Brainibot as it stands - the PIC is a 12C508
which is now rather dated. You'd be better using the 12F629 which is just
about big enough to run an interpreter suitable for compiled BASIC (the
i-code goes in the EEPROM memory).

Does anyone know of a compound shaft in Lego shafts? The primary purpose would be for a clock (minute and second hands) Thanks! Larry (20 years ago, 26-Oct-04, to lugnet.robotics)
