Subject: [alt-beam] Re: question


More expensive than a cpu? I don't know about you, but I am just finishing
a two motor walker with reverse, turn, and phototropic behavior, and it has
cost less than $100 CAN. If I were to buy all the equiptment needed for
programing even a basic stamp it would cost from $400 to $700, and it would
be VERY expensive if I didn't already have a PC. It may be expensive to
build beam bots from kits, but if you know enough to build your own from
technoscrap, it makes for a very interesting hobby (and inexpensive
compared to RC planes, and model railroads.)
just my thoughts,
