Taking Stuff Apart: Oster Battery Charger

-
I came across a battery charger for some heavy duty animal shears.  The thing had a nice heft to it.  Inside there were a couple relays, a barrel jack, some big caps and a bunch of ICs which I haven't looked up the part numbers for.

After opening it up it was apparent the failure was a diode that somehow cracked in half.  There were magic smoke stains on the underside and everything.

Here it is, as always click the pictures for higher resolution and additional pictures:

Easy and accurate SVG to DXF conversion using Inkscape and pstoedit

-
If you've ever worked with a vector tool to design something to be carved with a CNC routing machine, you may have needed to convert the resulting SVG file into a DXF. In my workflow I often use Inkscape to generate my SVG graphic, but my CAD software is CamBam and it requires a DXF file.

Many people have tried to make the perfect Inkscape plugin for exporting DXF, there is Better DXF Export, Better Better DXF Export and Big Blue Saw's DXF Export. I've had the most luck with the last one, but it was still finicky and often broke when updating Inkscape or OSX. Not only that, but at the end of the Big Blue Saw page, Simon mentions that he doesn't even use the plugin most of the time, instead relying on a command line tool called pstoedit.

With that in mind I made a small shell script which will convert an SVG file to DXF, you can save the script and run it directly or add the functions to your startup script.

The script is available on github under the project svgToDxf. …

Automated builds with Netbeans Platform 8.0.2

-
I've been converting UGS to run on the Netbeans Platform over the past week, and in general its been great.  The features and documentation I used while migrating UGS away from Swing were very well done. So aside from a couple hiccups, the Netbeans Platform has been great. Until a few days ago when I decided it was time to integrate my new changes with my Jenkins CI server.

It turns out that you can't build a Netbeans Platform application without connecting to the Netbeans IDE first. This has to do with the extra modules, platform components and build harness. Searching the subject online provides a lot of documentation, everything I've found is either out dated, contradictory, or I could only get it working with a new project and not my existing one.

The final solution was so simple, and minimally invasive that I wanted to create this blog post.

There are 4 interesting files for a Netbeans Platform build:
build.xml - Some documentation suggests adding a download-netbeans-r…

Taking Stuff Apart: Sony TC-800B Portable Reel-to-Reel Recorder

-

Today we have a Sony TC-800B to take apart. This is a portable Reel-to-Reel recorder is from the late 60's or very early 70's and is the same device that was used to record the watergate tapes. Unlike the TEAC 360S I took apart last week, this machine was very easy to take apart.

The one I came across even had a carrying case, you might notice that the handle is crooked. This thing was somewhat busted up, if you look closely you can see through the window in the case that the plastic covering the reels is cracked too:
