Subject: [alt-beam] Re: Suitable for Framing


Hey were you in the Science Museum of Minnesota? On Thursday the Twin
Cities Robotics group had their meeting there. I would go, but it's 3-4
hours... ONE DIRECTION!!! I'll probably go next time though, and bring a
bunch of my robots.

I think I'll try to do some work on Spyder today (Actualy)!

I want to add reversers to some/all of my walkers. They are cool, but I
need to realy add some sort of sensing. I also need to find some springs
around here.

Bronco's spring arrangement is rather different. Instead of trying to
find 2 small springs with JUST the right tension, I found a heavier duty
spring that fit between the legs. That spring only styretches a little,
but it's a strong spring.

I also need to add an adjustable supply to bronco. I think it bounces a
little TOOOOOOO much!!!

Jeez! I realy need to work on MECI IV M, but I havn't touched it in
months! I know how to do the sequencing, but I also need to switch
control of the motors to a diferent source. I suppose a MUX would do
that fine, but I realy think I should get some expirience with
multiplexer chips. That's why I think I should do some reversers.

Anyone have a favorite reverser circuit to recomend??? it's been a long
time since I ordered any parts. I think I should change that...
