I want it to navigate through a maze of wooden walls. I'd also like the antenna to be a small quarter Wed, 16 Jan 2008 17:55:28 GMT bestbobleonard http://tech.groups.yahoo.com/group/thereminvision/message/199 http://tech.groups.yahoo.com/group/thereminvision/message/199 T, Could you send John or Myself an email address that is current? Thanks BobLenard Sun, 27 May 2007 17:05:26 GMT ti_wrex http://tech.groups.yahoo.com/group/thereminvision/message/197 http://tech.groups.yahoo.com/group/thereminvision/message/197 Hi, Wow that's cool! A few people have asked about making music with them directly which is normally a little hard to to all the digital stuff. But with a Sat, 26 May 2007 19:04:05 GMT bobby cossum http://tech.groups.yahoo.com/group/thereminvision/message/196 http://tech.groups.yahoo.com/group/thereminvision/message/196 saw the theremin vision 2 in a device called the multimodal music stand last weekend at the maker faire in san mateo, ca. it was connected to a pc via a board Mon, 09 Apr 2007 03:01:12 GMT ti_wrex http://tech.groups.yahoo.com/group/thereminvision/message/178 http://tech.groups.yahoo.com/group/thereminvision/message/178 Hi Bruno, I split the sensors for larger robots. Perhaps the size of a car where such long antenna leads might be a problem. However, for a small robot a Sun, 08 Apr 2007 23:45:16 GMT Bruno Santiago http://tech.groups.yahoo.com/group/thereminvision/message/177 http://tech.groups.yahoo.com/group/thereminvision/message/177 Hi Terry, My name is Bruno, I'm a electrical engineer student from Brazil and I'm new on this group. I've just started designing a 3kg sumo robot, after a few Tue, 03 Apr 2007 23:44:00 GMT benedict-list@... http://tech.groups.yahoo.com/group/thereminvision/message/174 http://tech.groups.yahoo.com/group/thereminvision/message/174 ... Ehhh... Probably not fast enough. Slow enough, rather, to let the 9V driving the whole works get hot. Yeah, I may go ahead and see if I've got Tue, 03 Apr 2007 22:31:04 GMT ti_wrex http://tech.groups.yahoo.com/group/thereminvision/message/173 http://tech.groups.yahoo.com/group/thereminvision/message/173 Cool! Chips don't like to run backwards =:O Not sure if they would be killed or not, depends on the current and how fast the plug got pulled... I would Tue, 03 Apr 2007 19:39:44 GMT benedict-list@... http://tech.groups.yahoo.com/group/thereminvision/message/172 http://tech.groups.yahoo.com/group/thereminvision/message/172 Man, you nailed it. Two chips are backward on my board. (Which just goes to show me: DON'T SOLDER UP BOARDS AT 5AM BEFORE HAVING COFFEE!) I should have a Mon, 02 Apr 2007 18:18:18 GMT benedict-list@... http://tech.groups.yahoo.com/group/thereminvision/message/171 http://tech.groups.yahoo.com/group/thereminvision/message/171 DOH! Lemme check that when I get home tonight. Looking at the docs, I'm pretty sure you nailed it. So the next question, before I madly unsolder the chips: Fri, 30 Mar 2007 23:39:12 GMT ti_wrex http://tech.groups.yahoo.com/group/thereminvision/message/170 http://tech.groups.yahoo.com/group/thereminvision/message/170 Hi Tom, Double check the orientation of the ICs. U1, U2, U3, and U4. They were placed to make it small and keeps the wires short. A backwards IC is possible Fri, 30 Mar 2007 22:19:03 GMT benedict-list@... http://tech.groups.yahoo.com/group/thereminvision/message/169 http://tech.groups.yahoo.com/group/thereminvision/message/169 I was finally able to get back to my TV-II setup and wired it up to an ATMega168. First thing I noticed was that the ATMega stopped working when everything Sat, 24 Mar 2007 03:04:13 GMT benedict-list@... http://tech.groups.yahoo.com/group/thereminvision/message/164 http://tech.groups.yahoo.com/group/thereminvision/message/164 Thanks! I hope to be messing with it this weekend. The week's had a way of getting between me and my play time.

If the sensors were say 3400, 3000, 3200, 3100 uS pulse width normally, the processor would just normalize Tue, 20 Mar 2007 11:44:24 GMT benedict-list@... http://tech.groups.yahoo.com/group/thereminvision/message/162 http://tech.groups.yahoo.com/group/thereminvision/message/162 Got my ThereminVision II kit today. W00T! Gonna be soldering tonight! Thanks again to Terry and the folks at RobotLand for dealing with me. Tom
