Subject: [alt-beam] all powerful light


Light is the food of BEAM robots. Natural sunlight is
by far the best (I'm sure everyone has tested this).
But it isn't always bright and sunny out. Most of the
time people use lights. I was just wondering what the
best sourse of light is (excluding sunlight). Do any
types of light ruin the solar cell or anything like
that? What type gives you the most punch?
Thanks,




Aaron

the places, the barber shop had a Pitsco-Legodacta 2000 catalog. They
had two motors listed. The one where it said "with gear reduction" was
priced at $10.25. (the other was probably just a motor - was somewhat
cheaper) I have seen people on this list quoting the Lego motor at $
11. Is this difference because we may have to pay shipping at Pitsco?

12217 Mon, 20 Mar 2000 22:49:20 GMT [alt-beam] banners@beambotix beam@sgiblab.sgi.com "Mike Kulesza"
I'm really sorry that beambotix had to resort to putting a banner up on
itself. But I chose the smallest one available (88 x 31 pixels). I know
BEAMers don't appreciate banners, but I've got to make some income in order
to produce new bots, and purchase equipment (ie: digital camera's etc...) in
order to improve the website.

It would help a great deal if you guys could "support our sponsors" by
clicking on the banner, allowing the page to load, and returning to
beambotix. And only click when you feel like visiting the site; Please do
not feel -obligated- to click.

Thanks in advance

Flexible PCB material is available. You may have seen pieces of this
wrapped around in cameras. They use fiber glass for somewhat thicker
grades. This withstands soldering without much problem. If you want
real thin (like the ones in cameras), the backing material is polyimide
(ever heard of Kapton tape?). This material also withstands high
temperatures quite well but is very expensive. Kapton tape is used in
wave soldering to protect the gold plated edge connectors from getting
wet with solder. I think Kapton is somebody's trade name.

Fiber glass is translucent but kapton is almost transparent. However, I
have seen it only in dark reddish color so that may be the color of the
material itself. You can buy Kapton tape from many sources in different
widths but I haven't seen any retailer selling the (polyimide) PCB
material. May be this is something for Dave to look into. Buy it in
bulk & make it available to us in small quantities?

Now thinking about it, I have seen some bands of flexible PCB-like
material in older dot matrix printers to connect to the print head. May
be someone who has a junked printer can report on the suitability of
using that material in some way?

12219 Mon, 20 Mar 2000 17:29:58 -0600 [alt-beam] ....yet again..... "BEAM Mailing List (E-mail)" "Scolman,Jim"

Please forgive my density, but I feel I must keep asking this question until
I understand the answer. Thanks to all of you that have trie to answer my
past questions......but yet again....in the enclosed diagram, one of the
power leads goes to the
(+ plus) sign, where does the other go?........where is the (- neg) symbol?
Is this a Bicore, MicroCore, or UniCore? All the "stuff" inside the outline
of the chip.......is that internal to the chip or are those parts and
connections to be fabricated and soldered? I still don't understand about
ground.......where do you connect the 1G and 2G pins? The R1 resitors that
just end in an arrow head......where do they connect? I am electronically
challenged, but want to learn and build one of these things.....I have
studied the FAQs and looked at the tutorials.....really. Thanks for your
help......JWS. <<240UCORA.gif>>
