I've got a magnetic compass to hook to Trippy and hope for no smoke this time! I've got to figure out what diameter to use for tool compensation so things on...
I'll be there working on the SPI slave side of the controller. I'll probably not be there until 9 thought. From: tcrobots@yahoogroups.com...

I got ambitious and upgraded it so it has 6 LED's and 5 photo transistors. This gives me 10 sample points. I also wired the motor control wires to the Mega168...
This merger could make things interesting http://www.247wallst.com/2008/10/atmel-merger-od.html Will it be a PIC AVR or will it be a AVR PIC? Or would...
Bill Grumble please call me about the scooter base. I need to know when you can pick it up. I also have 3 monitors I am giving away. Is anyone intrested? I...
Some of you have seen one of the infrared camera products that my group builds. This is a good group of people and we get to do some really cool stuff, plus...
I won't be at RSOH either. I'll be in Grand Forks for the weekend. Terry From: tcrobots@yahoogroups.com [mailto:tcrobots@yahoogroups.com] On Behalf Of Alan...

I have an underwater explorer project in the works. When completed, it should work like the RUV on Titanic, except without the robotic arms. With a $35...
I will host RSOH 'south' again at my house in northern Burnsville Friday. If you need directions, give me a call 612 2O9-6779 I have a pretty big lathe/mill...
... Friday is a long ways off. But I don't have plans. I don't have any machining to do at the moment. Maybe we can discuss Robomagellan or Firefighting...
I have my NetBurner based line follower ready for the show. I also drew a oval on a 22x28 inch piece of paper for it to follow. I just don't know how long the...
I could be interested in the netburner board. I have several things you might want, like DSP eval kits and stuff. What do you need? Brynn On Thu, 09 Oct 2008...

Hi everyone, Does anyone know of someone who is knowledgeable about the certification process for low power RF devices covered by FCC part 15 rules? I am...
I've used my Wiring board to drive an H-Bridge, and worked up an opto-isolation circuit using 6N137 chips to separate the motor power from the controller...
... I've done FCC emissions testing, but not part 15. Lucky for me the FCC does not consider 800 hz to be a transmitted signal ... as we stayed below 10Khz. ...
... That depends on the amperage vs the beefyness of the wiring and the resulting "ground bounce". At less than one amp it's cheaper to just use multiple...
If your device is an active transmitter you can get by without testing unless you sell it or make more than five. Â "15.23 Home-built devices. (a) Equipment...
... Thanks, I'll do that. I've got 4 servos (two pairs for pan/tilt camera mount) to run and I knew that was way more than I wanted to take off the Wiring...
... I've found that R/C servos need a really stiff power supply that can supply high amounts of current for a few milliseconds to keep them from jittering. The...
OK, I'm putting out a request to see an ovagraph at the meeting. I'll definitely be there this Thursday, because I'm taking my mother to an appointment before...
Yeah. You’re busted if only you get caught. Seriously, in a nutshell you are in violation if you are causing harmful interference of licensed transmitters....
I do not have a ‘smart charger’ that automatically shuts down when charge is completed. By Power Wheels lore, the 12V 1amp charger charges two depleted 6...

Hello, I shall take my LEGO NXT line follower as well. I have printed the track for the robot. I shall take it to our meeting this week. jm. ... From:...
