12497 Sat, 25 Mar 2000 05:45:13 PST [alt-beam] Allmost complete walker. beam@sgiblab.sgi.com "sebastiaan van Vliet" I've built the "allmost complete walker" design from Ian's page. How
can i
turn the frequency down? I allready doubled all the cap's.
The schematic is great, good beginners stuff (like me). On Ians page
there
is another schematic with two tactile sensors. How is that
connected? what
are the "In's" for?

Depends on the motors you use. The circuit will run fine at those levels, but
gearmotors that draw to much current will make for lackluster performance.
Gearmotors that draw less than 20ma are your best bet and ones that draw less
than 10ma are ideal. That's why those PortEscaps are so popular for solar
applications.
See ya,

Roughly a meter or so depending on surface features and battery power level.

It won't open. Could You re post it.
It would be appreciated.
Thanks
So long,
