Just a reminder: we'll have our next SMART meeting in two weeks. The mini-challenge is to build a plotting robot of some sort. If it can draw, color, paint or even just make a pretty line on some sort of surface, it counts! See you in two weeks! -- (...) (14 years ago, 12-Mar-11, to lugnet.org.us.smart)

We had a nice SMART meeting today, though because of the weather, not too many people showed up. Nevertheless, there were a few very interesting 'tracking' robots. Great job, everyone! For next month (March 26th) we voted on building a "Plotting (...) (14 years ago, 27-Feb-11, to lugnet.org.us.smart)

(...) No, purely resistive. Although it does have a "boot up" time, I think it's just due to heating up the element. I'm not completely sure if the element will respond better to a "dimmer" type set-up (running it at less than normal voltage) or a (...)
