Alright guys and gals! It's time to stock up on those hard to find items that only
Solarbotics carries. Dave has slashed
the prices on many items for the month of June! You can get the solarcell multipack special and
while your at it, grab some caps for half price. Check out the
Price List for more deals.
I think I speak for everyone when I say, "Thanks Dave!".
The prize list for my Most Innovative Form of Motion contest has been
finalized. It sure looks impressive don't it?! Get crackin' on your entry...you only have two
months of building time to go!
Ian got a summer job at LANL working with Mark Tilden. Some guys just got all the luck!
Jason has finished "Chiuwalka". Go to
BEAM Land for some great pictures.

After a relaxing weekend in the booneys...I'm back to building!
MicroMo has come out with a new one. Check out the World's Smallest Gearmotor.
Here's a cool link to The
University of British Columbia Solar Car Project.
Ian has loaded 10 more images of Mark Tilden's robots to BEAM-Online.
Darrell Johnson made a new BEAM site.
BICOREEOS has lots of detailed pictures of his awesome bots.
Jester's BEAM Robotics has

Mark mentioned this to me in a recent e-mail but I couldn't find it in my TV guide...

Chiu,
I'm no longer on the list, so I don't know if this has been mentioned yet, but I didn't
see it on your page and thought you might be interested. I just saw Tilden on a show called
"Voyage to the Milky Way" on PBS. Great shots of Roswell and Snake, some minor discussion of what
they are all about. In my area, the next showing is Sunday at 1pm.
Anyone who caught it
on tape willing to send me a copy?

Chiu,
An upate on the "Auto Zoom/Auto Focus Lens" assembly, part number TM98OPT3202, from
Herbach and Rademan. I just received my order today :^) included in the shipment was their new
catalog. The same assembly is now $39.95, $10 more !!!! I guess they wised up :^( You may want to
include an update in the news tidbits.

Those greedy little...

The Bug-EYE Group, Alelaide University.
The BEAM Heretics Board has a few new
updates. Snoop around in the BEAM people section for new stuff on Lurch by Zoz and Gold Board

BotDoc has posted his Page O' RoboMadness. I really like SAL's head, nice work!
Check out Jakub Pietracha's first walker, GUCIO. It was built using Bram's walker tutorial.
Mark Tilden has joined the BEAM

Here's a clip from an e-mail sent to me from Steve Anderson.
By the way, last week I remembered the newsgroup msg from Jonathan Wolter regarding the BG
MicroMo's. He said that Herbach and Rademan had them as "Mignty-Might Gearhead Motors" part number
TM97MTR3083 for $19.95 each. Well I dug out my trusty catalog and lo and behold, not only did they
have them, but upon a more thorough examination of the catalog I also found that they had an "Auto
Zoom/Auto Focus Lens" assembly, part number TM98OPT3202, which looked promising. Gave them a call
and inquired if the assembly still had the motors attached. BINGO, two Nihon motors, one lens
assembly for $29.95. $5 cheaper a piece than the Mighty-Mights and with some free optics thrown in
for good luck. Approximately 300 left when I ordered mine last friday. Only approximately 100
Mighty-Mights left.
Call 1-800-848-8001 to request their catalog.
Finally Steven has got his Suneater circuit down to just one chip.
Suneater V is the
latest and greaest in this family of very capable photovores.

Dennison has thought of a great idea (why didn't I think of that). As most of you don't have video
capture equipment, I'll be accepting VHS tapes of your entries to my
contest. I'll post clips of the video on-line for you. Try to keep them under a couple
minutes long. E-mail me if this is the best solution for
you.

Study BEAM and get a high school credit! What more can you ask for?!?!?

Newbridge High School (private non-sectarian) is offering a beginning electronics and BEAM robotics
class for three weeks in June. The class will count towards physical science credit for high
school. The class is open to 8th-12th graders and will teach soldering and fabrication, reading
schematics, basic electricity and circuits, etc... I have been teaching this class during the
fourth quarter and so far we have built solar-rollers (they cover almost 10M in a few seconds!),
flashers, trouble-shot solar engines and VCRs. We pull our motors from pagers, CDs etc., and have
a lot of fun with walkers. Newbridge School is in west LA - Culver City area.

especially like the "A View From Gary Larson's Far Side" page.

A new section has been added to my BEAM site. Wilf Rigter recently joined the BEAM community and
has since demonstrated his impressive skill at dreaming up pretty little BEAM style circuits.
Rigter's NuPages is a
collection of his postings.
Yet another prize list addition. Rick Diaz is going to donate a pair of 64:1 Escap 22 gearmotors
for my Most Innovative Form of Motion Contest. I wish I could enter
one of my bots but I guess that isn't going to work...me being a judge and all!!! ;-)
