I have just returned from Brickfest 2001 which was a GREAT event.
Thanks to the WAMALUG folks for putting on such a well organized
and interesting weekend.
I was a little disappointed to find that Tim Courtney and I were the
only two people out of 150 to show up with RCXs! He had the
remarkable Jin Sato Mibo with him which is a "must see to believe"
piece of work. So where was everyone else? Are we really so few and
far between?
... and on another topic, I would like to invite anyone interested in
Technic or Mindstorms or RCXs to visit www.hitechnicstuff.com
You may find it interesting. With appologies to readers of this
news group for making such an announcement.

I guarantee you will find it interesting! This is fantastic stuff, I am
looking forward to seeing a price list on there :-)

I has used that IR sensor to instead LEGO light sensor in RCX Controlled
Trains, I have to say it is better than light sensor, and you don't need
extra external light source.

I've used John's "Four Channel Remote Control". It has always worked
without fail. It works in a couple of modes, one of which is perfect for
skid-steer type applications. There has obviously been a lot of thought put
into his design.

Hello,
I was recently at the Museum of Science and Industry in Chicago and in the
green stairwell they have a display of mechanisms that modify rotational
movement. I took pics of them all and I thought folks might like to see them.
There are descriptions with each, but I couldn't get them in the picture very
well. I hope they inspire somebody as much as they did me!

P.S. they have a Mindstorms workshop you can do there, about 40 minutes long,
but I skipped it as there was too much else to see. What an amazing place,
it's worth it's own 2-day vacation to Chicago. Add another day or two to
swing over to the Field Museum (home of Sue the T-Rex). For any dinosaur fans
out there I was hoping to see the Jobaria Tigedensis mounts that Paul Sereno
did, but they weren't anywhere that I could find.

Thanks for the pictures! If that's the stairway, I'm
very interested in seeing the rest of the museum.
I thought the square gears at the end had an offbeat
charm, though I don't really see how they produce
linear motion....

Exactly, it's amazing.

Oh they don't, they fall under the catch-all of

What they do is change constant speed rotation into alternating fast and slow
rotation.

Those mechanisms are great! Is anyone here aware of a online library(s) of
similar type mechanical devices?
Cheers,

Very interesting indeed!
I have a few questions:
In what way is the IR sensor different (better?) from the regular light sensor?
(apart from the obvious wave length difference)
It appears that one picture appears twice in the 'Products' page
(http://www.hitechnicstuff.com/RFs1.jpg)
What is that a picture of?
I don't think it matches either the description of the compass or the receiver.
Can I have more info about the remote control?
What is the relation between this one and the one Jennifer wrote about?
(http://news.lugnet.com/loc/uk/?n=5945)
Can you control the direction of all four motor? How exactly?
How does the bigger keypad look like? How about 'continuous motion' buttons
like the ones Jennifer talked about?
Are the dual connections designed to handle more current?
Is there any way of controlling the remote using a computer?
What is the power source of the transmitter?
Sorry for all the questions and thanks in advance for any answer,
- David

Hi John,
BrickFest was a blast, but it was pretty sad the absence of Robot heads at
the event. I've promised to myself that I will take some stuff with me next
year, and I even volunteered with WAMALUG guys to run some Mindstorms
competition/challenge event like a Sumo Wrestling.
I can't wait to get the pricing information of your sensors, I'm really
interested in all of them, I've seen them working and I can't but recommend
them highly to all those Mindstorms builders out there.
Good luck!
Jorge F.

I came very close to bringing my Technic Scale P-51 Mustang Fighter to
Brickfest, but after a few months of sitting around, the gears in the
drivetrain settled such that the propellor no longer spun. Next year I'll
try to bring something technic, and I hope others do too. (It's another
category to win in the MOC contest. hehe)
