Fishies in the Forest

  This project is yet another node in my home’s sensor network.  It needed two main functional parts: (1) a motion sensor across the entryway to my bedroom, and (2) a switch to control the lights on my bed (my canopy bed has lots of little LEDs hanging on it).  It would communicate wirelessly with […]


Flower Chandelier, part 5

I finally got around to making a light-switch for the chandelier.  Weirdly, this wasn’t a huge priority – since the chandelier can be controlled from my main computer, I didn’t need to make a dedicated switch to control it.  Having a light-switch on the wall nearby, though, is convenient.  I didn’t want to always have […]

The chandelier has been installed! My dad and I mounted an aluminum beam to a concrete beam near my ceiling, and the chandelier hangs from that.  Once the chandelier was hung, I added the butterflies that hang from the bottom of the chandelier.  I still need to make a light switch so that I can […]

Queue the trumpet fan-faire!  All the parts for the chandelier have been finished!  This article is a quick photo journey through the assembly of the chandelier.  Most of the difficulty in this project was designing and making all the parts.  The actual assembly was fairly easy.  All the parts are stacked onto a central rod.  […]

I’ve been busy, busy, busy designing parts for the chandelier.  The picture to the left shows a rendering of the parts I modeled in CAD.  I dragged my Dad into the project for the wooden parts – he has a lathe and I don’t, but mostly because he’s really good at woodworking.  (Thanks Dad!)  He also […]


Flower Chandelier, part 1

All right, I haven’t written for a while and it’s because I’ve been busy designing my next project – a chandelier that will hang above my dinette table!  This is so fun!  I worked up an approximation of what I want in Googly SketchUp, shown in the picture to the left.  The white parts are […]


Christmas Village Streets and Streetlights

I have several Christmas village buildings and props that I put up each year on my fireplace mantel around Christmas.  This year I decided to make streets and a backdrop for it.  The streets and backdrop are ink-jet printed on thick photo paper.  The backdrop was also glued to foam-core board. Over the years I’ve accumulated […]

Main Board (piggybacks on Arduino Mega)

Crystal Ball Lamp, part 3

—— The Electronics —— In this post I’ll discuss the design of the electronics part of the Crystal Ball Lamp. The lamp is controlled by an Arduino Mega microcontroller board.  I was originally going to use a less expensive Arduino Pro Mini.  It doesn’t provide enough PWM outputs for the nine LED channels I wanted to control, […]

Crystal Ball Lamp, part 2

LED drivers – LED Supply power supply – LED Supply custom printed-circuit boards – BatchPCB.  I like how easy their web-based storefront makes it to submit designs to have produced, but they keep messing up my orders so I may have to find another place to have my circuit boards made. whew.  I think that’s […]


Crystal Ball Lamp, part 1

I purchased some high-powered RGB LEDs from Sparkfun Electronics mostly because I wanted to play with them enough to learn how to use them, but also because I thought I might use them in a chandelier I’m going to make to hang over my dinette table. As I played with them, I realized that they […]
