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 (...) (23 years ago, 17-Jul-01, to lugnet.robotics)

(...) I guarantee you will find it interesting! This is fantastic stuff, I am looking forward to seeing a price list on there :-) Jennifer Clark (23 years ago, 18-Jul-01, to lugnet.robotics, lugnet.technic)

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. Zhengrong (...) (23 years ago, 19-Jul-01, to lugnet.robotics)

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. -Tim (...) (23 years ago, 19-Jul-01, to lugnet.robotics)

| | Rotational -> linear motion pics
|
|
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 (...) (23 years ago, 23-Jul-01, to lugnet.robotics)

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.... (...) (23 years ago, 24-Jul-01, to lugnet.robotics)

Those mechanisms are great! Is anyone here aware of a online library(s) of similar type mechanical devices? Cheers, LINC "Elijah Meeker" <lego-robotics@crynwr.com> wrote in message news:01072309144203....ldomain... (...) (23 years ago, 24-Jul-01, to lugnet.robotics)

(...) 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 (...) (23 years ago, 24-Jul-01, to lugnet.robotics)

(...) 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. Elijah (23 years ago, 24-Jul-01, to lugnet.robotics)

(...) 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 (...) (23 years ago, 24-Jul-01, to lugnet.robotics)

(...) 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 (...) (23 years ago, 25-Jul-01, to lugnet.robotics)
