Nice guy! You making fun of waramps or my crawler? Maybe I should compare
it to a lame "trojan" horse on two front legs and two casters up the rear
end. heh heh! Seriously though, BEAM walkers as exoskeletons for paraplegics
is an interesting idea.

don't take some things too seriously, ever!

www.protel.com

has demo versions of their software. Protel 99 was just released and
claims some interesting features. I've used Protel 98 extensively. . .
Well, at least the schematic capture, PCB layout and auto-router.
The demos are self-disabling after 30 days. You may find the learning
curve fairly steep.

Other packages that may have demos.

Eagle
OrCad
Tango

sci.electronics.cad

is the newsgroup that discusses this most often.

Cheers,


Richard.



6454 Wed, 6 Oct 1999 18:33:58 -0700 [alt-beam] Re: circuit "'beam@sgiblab.sgi.com'" Wilf Rigter Use a bicore with 1000 pf caps and put the buzzer where the motor nomally
goes. Add some photo diodes and the sound frequency and harmonics will be
light dependent. Use two coupled master bicores with two buzzers to hear
the sounds of chaos.
