Hi,
>Hey that will be great ian...one thing i would really like to ask u...how
>did u make mantis 1 so configurable and did u make aa new brain for
>it?...
Nope same old Mantis. I use it because I made each bicore on a seprate
PCB and PCBs for the H-bridges and reverser so it's real spread out and
easy to get to stuff. I also have a bunch of machine pins (out of IC
sockets) so I can just plug in different size resisters....
>ermm i got some questions about beamants i would like to ask u....what
>value did u use for all the resistor and capacitor....
Ummm. Forgot. It's on the BEAMant page on my web site. It's whatever the
values are in the schematic (not Mark's drawing). I think .22uF and 1M.
>and did u use mark's scketched schematic?
Yes and no.
>i would like to know so i could know the best behaviour
>out of it..thanks a lot and do u have any good tips for me and others ian?
Read
Experiment
Research
Build
Ask questions
And most importantly, HAVE FUN!!!
>for the beamant....and how did u configure your bots leg to turn....
Not much! just bent the tips of the back legs down to increase traction.
As for CW2 I've got a schematic layed out on paper and just need to draw
it out nice on the computer. I'll have it done late tonight or tomorrow
so check the site. I'll be able to fit everything on two chips and if you
want it to back up and then turn on it'll be 3 chips with plenty of
inverters left to mess around with.
