100 Watt RGB LED Lamp


Since I’ve been working on this project for about a year and a half, and my motivation has continued to hold up, I think it’s time I wrote a bit about it.  Understand as you’re reading this that there have been many dead ends along the way (I haven’t written about most of them here) […]

Project idea: Doomagotchi

Arduino Slide Viewer Slide Show


Quite some time ago, I found an old slide viewer in an antique store, and had an idea for a neat little hack. I finally finished the hack, and I’m pretty happy with how it turned out. Slide Viewer I took a 1.8″ TFT LCD from Adafruit, some AAA batteries, and a couple other bits […]

Voyager Combadge

I’ve been working on it for the last couple weeks, telling her that the workshop is out of bounds because I’m working on a secret project.  She knew I was cooking up something for our anniversary, but she had […]

As you may recall from that previous post, I spent a […]

I’m going to be exhibiting some of my creations at Vancouver Mini Maker Faire in a couple weeks, and I’ve been frantically trying to get everything in order before then.  I realized a couple weeks ago that I’m not […]

Slide Viewer LCD Screen

On the weekend, I found another awesome old slide viewer in an antique store, and decided to mount an LCD screen in it.  I was going to do it with the one I found a couple weeks ago, but I like this one better.  So, after a few hours of soldering ribbon cable, and cutting […]

Animatronic Yoda 2.0: Eyes, part two

I made some good progress last night re-engineering the eyes.  As you may remember from the previous post, the servos were getting in the way, so I needed to move them.  Well, success! The one on the left is the original, with the servo directly under the eye.  The one on the right is the […]
