I've always wanted to give making a "circuit sculpture" a try - where the circuit is built freeform in space from brass rods and "floating" components. Here are some photos of my first attempt - which is a clock, of course. It was a lot of fun to make - I will definitely be trying this technique again at some point.

I just realized that I never posted a finished photo of the lixie clock I was working on in this post. Here it is in all its glory. It looks much better (and more readable) in person - for some reason it never really looks right in photos.

I built this domino clock to add to my collection of clocks at work. It's made of built-up layers of thin MDF cut on the laser cutter, with neopixels behind the dots. The first domino is hours, and the last two dominoes represent the minutes.

This is the newer, thinner version of the word alarm clock - now with it's walnut enclosure.  This now sits proudly on my desk at work.

Years ago I built a one-digit Lixie clock that's now in my office at work. But I've always wanted to build a full six-digit version (with seconds), as that is way more interesting to look at. Now with the laser cutter for etching the acrylic and my new knowledge for making PCBs, this project idea finally seems ready to translate into reality. The photo on the left is a proof of concept of a single digit. The photo on the right is all of the various parts I've been working on to build the six-digit version.

This is version 2 of the nightstand-sized version of the word clock that I've been working on. You can see version 1 on the left, and version 2 on the right. As you can see, I definitely achieved my goal of making it a lot less deep! The new one is slightly less than an inch and a half deep. I redesigned the circuit for the new version to eliminate the separate Arduino and switched to board-mounted buttons (instead of the panel-mounted buttons the old one used). I also changed the way I did the light-separation grid to make it less thick. All of those changed made a huge difference in the size, as the first version was almost three and a half inches deep.

I built this narrow drawer cabinet to go under my electronics workbench, to give me a plan to keep some frequently used tools near at hand, and to give me a place to stash in-progress projects when I want to get them off the bench. The body is cherry, and I painted the drawer fronts black for some interesting contrast. It's only 10 inches wide, but the drawer are pretty long so it actually holds a fair bit of stuff. For some of the drawers I also used the laser cutter to make some sliding trays to hold the many small items I use a lot when populating boards.

I've been working on trying to come up with a version of the word clock I build that is in a smaller form factor - something more of the nightstand-sized variety. This is version 1. It still doesn't have a wooden enclosure around it, but it's definitely much smaller. This one uses a pair of PCBs that I designed and populated myself - one for the LED layer, and one for the rest of the circuit. It's still a lot deeper than I would like though, so I've been starting to plan for a version 2.

Technically, this is actually word clock #3 - as #2 is on my desk at work. But where I haven't taken any photos of #2 or posted it here, we'll call this one #2 for now. I made this for my sister's fiance Nate, after he saw the first one at my house and fell in love with it.

I've got the idea to make an Arduino-based metronome while I was between other projects. It's got a Neopixel ring for flashing the beat (plus a piezo buzzer) and displaying the current BPM, plus a pair of buttons for increasing/decreasing the rate. So, pretty simple - but kind of cool. I still need to figure out an enclosure for it - I'll post another pic once it's done.
