We had a great meeting a week an a half ago, and saw a lot of really cool drawing robots! The next SMART meeting will be April 30th, at 2pm.

(...) 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 (...)
