I have stumbled across a large list of low cost and free CAD programs, mostly for Windows however. It seems there are many good choices in the list and I will try out a couple in the next day or two.

about 3 months ago - No comments
This post introduces my open source radio control project. It allows an RC aircraft to be controlled from a Wii Nunchuk, i.e. with one hand! Videos will be posted when they are available but so far it is working great in the flight simulator and with a stationary aircraft.

Part Design Tools and Workflow
about 4 years ago - 1 comment
After spending quite some time trying different pieces of software I have come up with a collection and a workflow that I think will fit my needs.
I wanted to be able to accurately design parts in 3D, see how the parts will fit together to make sure they are right, and produce traditional engineering drawings

Windows XP and Stepper Motors

My first test after assembling the board was to connect one motor to each axis in turn and test using Windows XP SP2 and Mach3. The test involved going to the motor tuning section and pressing the up and down arrows.

Testing EMC2/LinuxCNC on Ubuntu 7.10 Gutsy

I just completed the first test of running EMC2/LinuxCNC on Ubuntu with the HobbyCNC board. I connected a motor to the X-axis and started EMC2 with the “Axis” interface. I then told it to execute the default G-code file it loads with. Lo and behold the motor started spinning! I then moved the motor to

I found out that the linux-rt kernel is not suitable for running EMC2/LinuxCNC. Sorry if you followed those steps. You can remove it using sudo apt-get remove linux-rt. Instead the kernel must be patched with RTAI. I’m currently working out the correct steps to do this. So far I tried the pre-built kernel in the

EMC2 requires a real-time kernel (which Windows XP and Vista are not). Installing it on Ubuntu 7.10 was pretty simple.
Open a terminal window
Run sudo apt-get install linux-rt and wait
