About me I've been a computer programmer since I first started typing in program listings on a Commodore Vic 20 when I was about 8. My hobbies include electronics, CNC manufacturing, photography, beer and winemaking.
I live with my wife and lots of left-over parts from unfinished projects in Lincoln, Nebraska, USA.]

15 July 2013, 14:29 UTCGot a 3D printer
I bought a 3D printer, called Rostock MAX. I'm keeping a record of my experience with it. So far it's just a work in
progress, but maybe this week I'll progress to the point that I can extrude
plastic. Later I'll make it work with LinuxCNC.
13 June 2012, 12:49 UTCStippleGen 2—Stippler, turned friendly
A long time ago I wrote stippler and put the source on my blog.
However, it was pretty user-hostile software and doesn't even build with
current versions of Linux without modification. That's why I'm gratified
to see StippleGen 2, free software (LGPLv2.1+) that performs a similar function
but with a nice-looking user interface. I haven't tried it myself, but
if you are interested in making this kind of art it surely warrants a look.
3 March 2010, 13:15 UTCRELEASED: emc 2.3.5
I'm pleased to announce the next bugfix release in the emc 2.3 series,

The new packages are now available for Ubuntu 8.04 "Hardy Heron" in the
package repositories. Packages for Ubuntu 6.06 "Dapper Drake" should
follow within the next few days. If you have already installed an
earlier 2.3.x version of emc, this will be offered as an update.
If you still have 2.2.8 or earlier installed, 2.3.5 will not
be available as an automatic upgrade. For more information and
installation/upgrade instructions, please see
the wiki
git users can get this release by checking out the v2.3.5 tag (or follow
bugfixes on v2_3_branch). Source tarballs are available from the
package repository:

Many thanks to the people who have contributed bugfixes for this
release.
