Yes, that's why I'd tend to the educational set, too.

Re: LEGO MINDSTORMS EV3 Pre-order Now!

Software sold seperately? I thought it was free? Or is it the education version that you have to pay for? The education software includes datalogging and some other stuff. The retail set will come with free software. = Xander So I can't programm my robots built from the education set unless I buy t...

I once tried to build a segway with only gyro data but i had great problems with drift, so this time i tried to use accelleration data and a complementary fi...

Re: Segway using a Wii Nunchuk/WM+ for balance

Last week i built a segway using a nunchuk (for accelerationdata) and a WM+ (for gyrodata) but i've come across two problems. First, it seems to take about 40ms to read the nunchuk and gyro. That seems too much imo. I can't get the robot to balance perfectly, it just reacts to slowly. It's always th...

Re: Dexter NXTChuck

May I ask whats on the NXTChuck PCB? I guess only the pull-up resistors and a voltage level converter?

So practically I could use your NXTChuck lib with my modded Nunchuk and WM+? :D Your code is much better written than mine ;)

Re: Segway using a Wii Nunchuk/WM+ for balance

Re: Segway using a Wii Nunchuk/WM+ for balance

I once tried to build a segway only with a wii Nunchuk but i failed. Possible though that i just wasn't good enough.

Re: NXC: functions with different numbers of parameters?

float max(float f1, float f2, float f3 = FLOAT_MIN, float f4 = FLOAT_MIN, float f5 = FLOAT_MIN); Where FLOAT_MIN is the smallest possible float number (you would have to define this first of course). You could call this function with two, three, four or five parameters: float max(20.5, 3.8); float ...

Re: Building large wheels

If you have the necessary tools you could cut them out of wood.
