try an efficiency course......welll more of a test.on one "pop" see what
B.E.A.M. goes the farthest(size,gearsbox(if any) , sunlight would hafta be
full sun......
just an idea

Can they cause problems? When?
I allso heard someone saying that all te unused leads should be grounded ,
How important is that? the schematic leaves them unused.

need SOMETHING to do with my web time(23.3hours a day) so this would be
undaunting...so if anyone is interedted , send ALL PICS , SCEMATICS , TEXT

please zip the files if you can...if not......i will take them anyways...
thanx

12714 Wed, 29 Mar 2000 15:14:09 EST [alt-beam] 6' x 6' solar panels beam@sgiblab.sgi.com SkavenArmy@cs.com I have ordered a collection of solar pannels from allelectronics...the solar
panels are 6 inches x 6 inches......im not sure what is ther output , but its
most definately higher than thos 22x22mm ones....(btw : they are dark cells)
. i will be selling them for 10$(s&h) or you can buy them from all
electronics....

12715 Wed, 29 Mar 2000 14:49:14 EST [alt-beam] Re: glider beam@sgiblab.sgi.com SkavenArmy@cs.com I have drawn up a few little infrared beakons that would mark certain plces
where to do certain stunts or whatever...i am looking into my model rocket
circuits for a lil bit of guidance(they have ones that when your rocket
reaches apogee(peak height) , it deplys up to two parachutes(back powerd and
electrec matches) .i would brobly use some infrared on the nose and wings etc
and have it so that if any of the infrared sensors are triggered (maybe hae a
plexiglass front cover to magnify it) the plane will go from this (

12716 Wed, 29 Mar 2000 12:24:30 PST [alt-beam] Burn beam@sgiblab.sgi.com "sebastiaan van Vliet"
Is it easy to burn a chip? I have a neat tutorial on freeforming the almost
complete walker wich I want to post within a day, but if it fries too
easily, maybe that isn't a good idea.

just so you nkow whats up at the homefront,
www.geocities.com/jaydzink
is working.....not all the links are right now(server crash last night)
but later today they will be back up online i hope

12719 Wed, 29 Mar 2000 15:35:49 EST [alt-beam] Re: Burn beam@sgiblab.sgi.com SkavenArmy@cs.com i have not burnt a chip yet (unless it was the last one).I suggest using chip
holders (radio shack sells them for about 50c each). I solder on to these and
then just " PLug & Program (c)"

same as the "e" field sensor discussed previously. It has the same problem
as all unterminated HC inputs, of oscillation and high power consumption.
Because the input voltage depends on leakage resistance it is unpredictable
in it's output state. A better solution is uses a high Mohm value resistor
from the HC input to the +V supply. Depending on the application that can be
from 1M to 22M. Use a 100K series resistor to protect the input from static
and reduce sensitivity to changing electric fields. The 2 transistor
darlington touch sensor can be replaced with a single 2N7000 mosfet with
using similar input components as the HC input for protection .

points about standardizing the course, i just wanted to get some input first
(this page was a quick write up of an idea i had a while ago). I do need to
polish up my greek (hey wait, i never took greek!) and i'll be sure to fix
some of those misused terms. My original idea, the one i probably should have
put up, was to have an RJP the size of a flipped over card table (that just
seems to be a good size, and easy to construct, just buy a card table!) and
create goals for the robot to knock down, index cards and goals that would be
penalties, black paper. I have the new photovore rules on .pdf, but i wanted
something more substantial, this didn't really push the robots limitations of
intelligence, though eventually i will build one, just for fun. If you guys
have test suggestion or anything you want me to replace on that page, email
me directly or just post it on the list. THANKS A TON!

12723 Wed, 29 Mar 2000 16:00:43 EST [alt-beam] Re: Burn beam@sgiblab.sgi.com BUDSCOTT@aol.com Frying a chip is easier with static than a soldering iron (or so i think) if
you have a grounded soldering iron (3 prong) it should be no problem. I still
do all my work with sockets, just makes life easier even if its bigger!

12724 Wed, 29 Mar 2000 16:02:58 EST [alt-beam] Re: 5%? beam@sgiblab.sgi.com BUDSCOTT@aol.com Depends, grounding is just a safe way to keep things from goin all hibbity
jibbity on ya. 5% tolerance? if thats what yer talking about, in some cases
yes. I had difficulties keeping my 'miller style' walker under control, the
legs would occilate one way more than the other, but if you use a 'chiu'
style walker, gravity does the work for ya!

12725 Wed, 29 Mar 2000 11:50:27 -0800 (PST) [alt-beam] looking for Stepper motors beam@sgiblab.sgi.com "Leonardo Boulton F." Hi, i found this photovore that works with an oscillator (square-wave),
and it works with two stepper motors. Now, where can i found such
motors.... i understand some clocks work with stepper motors, but are
there any other places?....
And, i don't have quite clear what the difference is between a stepper
motor and a usual electromagnetic motor.....
thx.
Leo

So you are considering using the 240ucore design for your first project but
be aware that it is a new design with little feedback from anyone who has
build it and likely will require some effort to debug. But then you may be
the first on your "block" to build one. As an alternative, the Tilden
master/slave bicore design in the form of Ian's almost complete walker is a
probably a safer project for beginners.
enjoy
