well I think that paper clips make a good frame.
They are easy to shape and solder to make a
very good and strong frame. It is also very easy
to change the angle of the front motor with them.
Hope that helps. Let me know how it turns out
good luck

I must have skimmed over it in the mass of highly interisting messages
to skim over! :)

too. i thought i'd use that as part of the frame. i can use copper tubing,
1/8in diameter from a local hobby store. this way i can mount the circuit on
the case! i think i have a good idea on how to mount those legs too! Thanks a
ton, it'll be helpful!

Yeah, we've been busy. Some idiot posted a note about robot
miniaturization, and that spawned many subthreads and much discussion.
Who was that, anyway? Zoz! It was you! It's your fault!

10769 Wed, 23 Feb 2000 19:41:13 EST [alt-beam] IC Chip Trouble beam@sgiblab.sgi.com BowfinGar1@aol.com In the master-slave setup it says to use 74hct240e.
I was woundering if I could change that to a 74LS245N or a 74LS244N?
Any help is thanked
Thanks
