Sony Digimatic Flip Clock Repair

In my frequent prowls through secondhand shops, I stumbled on this positively gorgeous piece of pre-digital electronics — A Sony Digimatic Clock Radio

Fully repaired, and keeping beautiful time now!

Fully repaired, and keeping beautiful time now!

As I found it, it wasn’t working properly. The clock would run slow, and get stuck for hours at a certain time, before finally flipping around to the next minute. Something was wrong, so I plopped it on my bench and laid it bare to see if I could fix it… Continue reading

New 3D Printer!

This evening, I went to a local 3D printer meet-up out at the Printrbot HQ in Lincoln, CA.  I came home with (most of) an old, first generation Printrbot 3D printer to try and get working.  Unfortunately, I’m missing a few vital parts, so I shan’t be able to get it up and running just yet, but I’ve certainly got enough to get started and do some testing! The photos are a touch blurry — I was using my phone camera, and did a poor job of focusing and holding steady.

Miniature Arcade Cabinet

Here’s the finished product! Ready to play a game of Centipede!


A while back, I thought about how neat it would be to make miniaturized arcade cabinets for folks who like the nostalgia of the 80s, but don’t want to have a full sized cabinet in their living room.  I started doodling in my spare time, taught myself Google Sketchup, and came up with a number of designs, before settling on this one.  Here’s a shot of the final sketchup design I came up with, after a whole lot of false starts:

I took the design, and transferred the pieces to Adobe Illustrator to create patterns, then starting with a cardboard model, I worked out some of the assembly kinks, and came up with the finalized plans.  Click through for a whole heck of a lot more photos and detail. Continue reading

Electronics Bench Power Center

I recently became fed up with not having switched outlets on my bench.  Plugging in and unplugging unswitched soldering irons and such became rather tiresome, so I started brainstorming solutions to facilitate switching individual devices on and off.

I had a brainwave one day, after spending a lot of time failing to come up with answers.  Here is my solution!

If you don’t recognize it, they were popular during the 90s.  Set your monitor on it, and plug all of your computer and associated periphery in, and have fun switching everything on and off.  Each of the five outlets on the back is individually switched, with a big master switch to control the lot.  Perfect for what I needed it for.

One problem.  Its ugly Continue reading

Epson scanner power jack replacement.

A while back, I was given an Epson Perfection 2400 scanner, complete with the top light for scanning film negatives.  The only problem was that the power adapter had been lost to the ages, and I had no way of powering it.  I had a look at the weird connector, and stuck it in the closet, in my “to do” stack of stuff.

Fast forward a couple of years, and I was spring cleaning that closet, and came across this scanner again.  I decided it was at the “keep or toss” phase, and since I still didn’t have a halfway decent scanner, I decided that I’d try and fix it.  Here’s the patient, in all its dusty glory!

On a close examination, it turns out that it takes 24v at less than an amp, but it takes it through a weird reverse barrel connector.  I searched for a while for the appropriate connector on a donor supply on the rack at goodwill, but was less than fruitful.  I had a 24v adapter that would power the thing, but couldn’t plug it in.  Then one evening, I was struck by a brainwave.  Remove and replace the connector on the scanner! An idea was born! Disassembly proceeded! Continue reading
