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)

Our last SMART meeting went really well! There were lots of really good robots that people built on the spot to solve the task presented! In fact, I had a couple of people comment that they would like to do something like this again on a more (...) (14 years ago, 16-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 (...)

(...) That sounds like a great plan though we did actually pick a mini-challenge at the last meeting. I should have posted something about it but I guess I never got around to it. My bad.

In just over two weeks we'll have our next SMART meeting. We'll meet at the new DigiPen building, from 2pm to 5pm. As no mini-challenge was posted, we'll try a very low-key variation on BrickHeap Wars for this meeting. It will be an individual (or (...) (14 years ago, 14-Jan-11, to lugnet.org.us.smart)
