Subject: hextile boards



Well, it seems that I have some nice hextile PCB designs. I have drawn th=
em from http:/home.swipnet.se/kristoffer/hextile.htm which were drafted by =
John A. deVries II.
If anyone is interested in these just say so!!! Now I have designs for Hx=
1.0 , Dx 1.1 and a Bc 1 (bicore) board.
I also made a SMD version of the Hx and Dx boards.
I'd like as many people as possible to see them and t say what they think=
of them because I'm still not sure if they
are 100% correct.
These boards shoud be double sided. Both sides are the same.
I don't know if this is legal because these designs are those I found on =
someone's site.

Can someone help me with the microcore...
I'm just building a 2 motor walker and the brain is still on the breadboa=
rd. It seems that motors aren't getting enough power.
They don't movelike I've seen on other walkers. They move to lazy and whe=
n I take the shaft with my fingers I can feel that =

the motor is realy weak. I use small geared motors that I found at Conrad=
.
I've tryed vith the servos too, but then happens nothing. Microcore does =
not have enough power to move servo at all.
Then I connected the H-bridge to drive the motors.........,,,,but stil no=
thing happens !!!!
Sometimes microcore resets itself (I mean LEDs flash with no order).
What could be the problem? Is it possible that all this happens because I=
use HCT chips instead of HC or AC ones?

Please help me or tell if you are interested in PCBs.
Thanks

Vlatko
