A PICAXE is a PIC with a boot loader preprogrammed into it. Arduino is an AVR with a boot loader preprogrammed into it. I like the AVR because it uses the very same GCC C/C++ compiler I use for everything else. I can test _some_ things on the desktop computer then recompile on the AVR. The Arduino is simply an AVR, on a standardized PCB. The decision to standardize means that you can buy standard daughter cards. You can build exotic stuff like web controlled stepper motor drivers with no soldering. I was very surprised to find the Labview bundle. It is normally a $5,000 package. But then I looked and found the Student version of Labview is always $20. And they don't ask if you are a student. (Actually however I am, at age 50+ I enrolled in the local community collage, music department.) I'm never afraid of "overkill" on a one up project. The last big embedded hobby system I worked on has an astronomical camera. One thing you have to do with a CCD image sensor is clock the charge off the chip then route it to an ADC. I used a full size desktop PC running Real Time Linux to generate the clocks or the CCD. Gross overkill but I could telnet into the camera controller and look around inside even with the camera on the other coast 2,000 miles away.
