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 (22 years ago, 26-Oct-04, to lugnet.robotics)
