We will probably have to wait two or three weeks to see the video.

I was getting less conservative with the routines and would not be surprised if ExSpurt ran out of the ring several Fri, 20 Apr 2012 02:05:43 GMT TRACY EIB http://groups.yahoo.com/group/ScienceCentralRobotics/message/286 http://groups.yahoo.com/group/ScienceCentralRobotics/message/286 I saw a few matches toward the end.  Exspurt looked really good in the few matches I saw.  Exspurt won all the matches I saw.  I didn't see Blackout at all Fri, 20 Apr 2012 01:42:12 GMT Rick Brooks http://groups.yahoo.com/group/ScienceCentralRobotics/message/285 http://groups.yahoo.com/group/ScienceCentralRobotics/message/285 Nope, no idea. I didn't see any of the video or heard anything. 32 entries sounded like a lot. I wonder how many were students and how many ship-ins.

Steve Tue, 03 Jan 2012 18:11:07 GMT Shane Pickett http://groups.yahoo.com/group/ScienceCentralRobotics/message/280 http://groups.yahoo.com/group/ScienceCentralRobotics/message/280 Yes, the event is still on. I'm getting ready to post the revised page now. Registration costs are changing, though. To the cost of admission per person.

Looking at the low side MOSFETs, you are driving the gates with 10 volts, but the high side MOSFETs, you are only Thu, 29 Dec 2011 23:36:59 GMT TRACY EIB http://groups.yahoo.com/group/ScienceCentralRobotics/message/277 http://groups.yahoo.com/group/ScienceCentralRobotics/message/277 Rick, Thanks for your reply.   I put 10K pull-down resistors on all the inputs, which are connected directly to Propeller pins.  I am trying to output to the Thu, 29 Dec 2011 17:55:23 GMT Rick Brooks http://groups.yahoo.com/group/ScienceCentralRobotics/message/276 http://groups.yahoo.com/group/ScienceCentralRobotics/message/276 Tracy, I don't know anything about that type of voltage regulator. So, I won't be of much help. I do know about the SN754410. Did you have 10k pull down
