I am coaching a team in the FLL contest. I need a supply of those 5 or 6 nub diameter foam balls -- at least 30. Does anyone have an idea of a source? Is there any similar thing that comes from Nerf?

It looks like they have changed the boards fairly significantly. Many parts substitutions -- notable the capacitor farm looks like it has been replaced by a battery backup capacitor. The overall parts count seems to be reduced in more places than (...) (26 years ago, 20-Oct-99, to lugnet.robotics)

I was wondering about the speaker as well. The old RCX definitely can beep, and make a whole host of other sounds. Not being an electronics engineer, I'm was uncertain of my ability to identify the speaker on the 1.0 board. It's not the thing that's (...) (26 years ago, 20-Oct-99, to lugnet.robotics)

Though it is not nearly as versatile as programing your own RCX/Palm communication interface, there is a program for the Palm (with IR) called OmniRemote. It will let you control the RCX with the Palm TODAY so you can see if you like the idea. I (...) (26 years ago, 20-Oct-99, to lugnet.robotics)

| | for loop stack overflow
|
|
THis may be a dumb question on my part, but we are getting stack overflows on for loops such as for(int i = 0;i<1000;i++){...} when using values over 100 or so. Is this an 8bit counter thing or something else? Thanks, Owen Popplestone (26 years ago, 20-Oct-99, to lugnet.robotics.handyboard)
