Rick, Oh no! That is a real bummer about your car. Three miles from the event no less! Congrats on your success with your other bots! Exterminator is a ...
Tracy, The prizes at Peoria are donated. They do a great job of hitting up the manufactures every year. I'm normally looking for merchandise that I can give...
NEIRG is a great competition with or without prizes. But I do think prize drawings would add another element of excitement to the event, and it might...
... It's kind of interesting. If you want to simply give prizes to the winners, you can look at NEIRG & BotBrawl (Peoria) and see what percentage of the prizes...
Steve, I agree - a drawing for merchandise prizes seems like a better way to go. You could even limit it to one prize per builder to spread out the winnings....
Tracy, I agree that prizes may add an element of excitement and possibly encourage more participation. I want to give you a more detailed idea of how prizes...
Tracy, Perhaps you should make a proposal to Science Central about merchandise at NEIRG in 2009. Remember that Lou and Shane are full time employees of Science...
I find myself in a bit of a jam, ...again, I bought a 850mAH 11.1v LiPo battery thinking that my son's airplane came with a LiPo charger that I could charge an...
Rob, Thanks for the explanation. I will definetely see you at the next NEIRG and maybe also at the next Bot Brawl. Tracy ... distributed ... 10 ... for ... ...
Rick, You make some good points that I didn't think about as well as information I didn't know. I like to discuss ideas on this forum, but I am not sure I am...
Tracy, 1. I have the Triton by Great Planes. It is hardly inexpensive, but does work very well for a wide variety of battery types. 2. Don't know. 3. I've...
Rick, (and Rob, Steve and whoever else...) I just found out that my daughter's dance competition on the weekend of the Chibotica is Sunday only - so my son and...
Rick, (and Rob, Steve and whoever else...) I just found out that my daughter's dance competition on the weekend of the Chibotica is Sunday only - so my son and...
Tracy, It will be a big time in Chicago, but it does conflict with UNI. I'm not expecting to get ExSpurt back in time for Chicago, so I'll have to use the...
Tracy, Nope. Work sure does get in the way of fun. I'll be watching it tonight. Rick ... From: Tracy Eib To: ScienceCentralRobotics@yahoogroups.com Sent:...
Tracy, Still no videos. Apparently ExSpurt won UNI with Thin Man (by Bob Cook, Vancouver, with relatives in Fort Wayne) in second. Almost time to leave for...
Rick, Yes - I saw the tail end. Congratulations! I think ExSpurt's handlers were more in tune with your intended instructions this year. Thin Man is an...
who someone would contact if they wanted OTS to come to their venue. Probably the outreach coordinator, but that isn't necessarily true for everyone, plus the...
I see on the schedule that the Robotics Faire is on August 2nd, in just two short weeks! Wow - that time went fast. If we are planning to participate, should...
Hi Tracy, Two weeks! I'm just getting back from four days in Ann Arbor and haven't thought about robots. We (Science Central and I) have been talking about a...
Ye Olde Robotics Faire is this Saturday, August 2 from 11:00 to 3:00. We should have lots of robot related displays and demonstrations. The plans are to have a...
I came across a great tip for anyone (like me) who is trying to build a robot around the Tamiya double gearbox. These are great low-cost ($10) motor-gearbox...
Tracy, Your meter is intended to measure steady state voltage. It has low pass filters to eliminate any variable voltage. When you try to measure the PWM...
Rick, OK - thanks for the warning. I do not want to damage the motors. Do you think running the 7.4V through a couple of diodes to bring the voltage down...
Tracy, I'd use the 7.4 Volts. Your motor control should drop about a volt or more when it passes a lot of current. Just take it easy on change of speed and...
Rick, I was thinking about what you said about the BJT motor control taking up a volt or more at higher current. Although my line follower does not need the...
