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:

XCode4: UITabBarController with UINavigationController using Interface Builder

-

If this helped you, please consider downloading my FREE  iPhone app " Hydrate Yourself "and leaving a review. There are a  whole   bunch  of  tutorials  to create a Navigation Controller inside a TabBarController with XCode3.  But there are a number of small changes in XCode4 which can trip up someone not familiar with them.  So this guide is essentially an updated version of those other guides, designed to create the same simple demo using the new tool. 1. Create a new Project We are going to start with a Tab Bar Application, so go ahead and create a new project as usual. I'm calling mine Navigation Tab Bar. 2. Select the Tab Bar Click MainWindow.xib and you should see the integrated Interface Builder. On the left is a section called Objects, select the Tab Bar Controller. 3. Add the Navigation Controller On the right side of your screen click the Utilities box. This is new in XCode4 and should look familiar if you've been using XCode3. At the bott

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

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:
