L3G4200D Tripple Axis Gyroscope + Arduino

Before we begin, just note, that while this all works, I believe the output is scaled wrong. The noise floor is very high. But from everything I have found it looks like this is how it is. We have covered, accelerometers, GPSs, compasses… But no gyros. Why? Not sure, but I figured today I would put an end to that, so I grabbed a L3G4200D 3-axis gyro from sparkfun. The L3G4200D is a 3-axis angular rate senso ...

Triple Axis Magnetometer HMC5883L + Arduino

One of the first articles we did was on the hmc6352 digital compass. Well this is his older brother (or younger but smarter). I really don’t know what to say about the HMC5883L other than it is a three axis magnetometer, so it is capable of sensing in 3 directions. That doesn’t mean that it is tilt compensated, because you really don’t know how it is orientated when the reading comes in. For that, you would ...

How to wire an arduino-based 3-axis CNC machine using arduino

I've seen a number of tutorials about how to build the platform for a 3-axis CNC milling machine.  I have not seen anyone tackle the tricky subject of the electronics. Here now is my attempt to do so. Step 1: Parts You'll need: - an arduino. I chose duemilanova. (depends on the board you get) - 3 stepper motors.  I chose NEMA 17s . ($15/ea) - 3 EasyDrivers from Sparkfun . ($15/ea) - some Cat5 ($2?) - a 12V ...
