Vendors I Like

I've noticed a few folks on LMR have mentioned their preferred vendors -- I though I might do the same on my blog.  There are more I'll probably add, but these folks are fresh in my mind. Everyone already knows about SparkFun, Adafruit, Electronics Goldmine, SeeedStudio/NKC Electronics and Gold Phoenix PCB -- this list includes stores I haven't seen mentioned.

My UAV ideas

I've been reading this site for the past week or so, and it has really inspired me to get more into robotics. I've had a couple of ideas for robots that I want to make in the future, I am going to start of with fritsl's starting robot, but I just wanted to share some of my future ideas to see what you guys think.

Happy Birthday

All over again

How do you know if your motors will be strong enough?

Hello Everyone,

I'm new to the LMR community and want to build my first robot. I'm a linux enthousiast so for brains I have an beagleboard. This has an 500MHz arm processor and runs on 5Volt at 2 watt on full load. http://beagleboard.org/

It also has 3 serial interfaces so I would choose a serial motor controller.

Norway LMR Beer???

Hi, everybody!

I know everybody is busy with his (her) own business, but I feel if I do not post it I will feel bad :) I'm i Stavanger, Norway at the moment for training. Enyone wants to meet for a beer in sake of robotics? :)
