As most of you know I've been exploring ways to revitalize electronics education via this blog and teachings at Lawrence Tech University and now ITT Technical Institute.What saddens me is the days of building electronic circuits on breadboards or (...) (18 years ago, 29-Mar-07, to lugnet.robotics)

(...) That's great news, David. I'm glad that you are having success using the new CommExecuteFunction system call. I haven't had a chance to test it at all yet personally but I was very confident that it would just work seeing as how exposing it (...)

(...) You can push the gearing still higher - 1:1 isn't the upper limit. But the trick with gearing is to match the gearing to the torque that the motor provides - and to use as few stages of gearing as possible. If 1:1 gearing is optimal - then (...) (18 years ago, 25-Mar-07, to lugnet.robotics)

First, I'm a beginner. So it will be very easy question for you guys. I have to make a lego robot with RCX model as fast as it possible. I just can use two motors and 4 wheels. It means I can use only a 'driving base'. I made gear ratio for 1:1, and (...) (18 years ago, 25-Mar-07, to lugnet.robotics)

Alexander, Thanks for the differential/pole-reverser idea. Based on your description, I was able to get a prototype running very rapidly! I'm still seeking a clean more mechanical version, but this certainly will work for now. Along the lines of a (...) (18 years ago, 23-Mar-07, to lugnet.technic, lugnet.robotics)

Do we loose points for melting the eggs? At any rate, it makes the foil stay on better. ;-) --Peter (18 years ago, 22-Mar-07, to lugnet.events.brickfest, lugnet.robotics, FTX)

(...) Will, If you do manage to combine RCX & NXT, I expect it will look mashed-up, but unlike all the other stuff at BF, this is not a how-does-it-look competition. No matter how it looks, I'm sure people will cheer for robots that try to give them (...) (18 years ago, 21-Mar-07, to lugnet.events.brickfest, lugnet.robotics)
