I'll try to write here about stuff I'm up to and working on.
Laptop bed desk
I had an old Ikea desk chair with wooden armrests that were forever wobbly. Their choice of fasteners was flawed, once regular use loosened the nuts holding the armrests on, they were impossible to tighten securely. No wonder they don't make them anymore. I decided to simply remove the armrests. Their form was very nice however, made from bent, laminated wood. It suddenly occurred to me that I could probably transform them into a laptop desk for a bed, and since I had promised to make one for Shannon anyway...
All it took was a spare Ikea shelf that had been floating around, I can't even remember what it was for, and a bit of trim ($2) to hide the raw MDF shelf edges. Some glue and some screws later, and...
I put the shelf under instead of over to get the height right.
What's really nice is that because of the armrest shape, the desk hangs nicely off of the end of the bed frame for storage. I quite liked that it worked out so well and easily, and repurposing the armrests instead of throwing them out feels good.

An LED ring light for jewelry photography
I came across this post on how to make a LED ring light for a camera and I thought I'd make my own for photographing jewelry and the like, instead of working up a more traditional three-point lighting setup. I ordered the same rings from dealextreme.com (90mm and 120mm), they took about three weeks to arrive and cost about $14 shipped. Then it was just a matter of getting out my dial caliper to take measurements and creating tool paths in Illustrator. From Illustrator I export to svg and then use Blender and custom code I wrote to generate g-code, which I run in EMC2 under ubuntu.
The scrap plywood I used has a very thin veneer face and it chipped a bit in one spot during milling. Oh well. The holes in the rings are for passing through the LED ring wires.
My camera (Canon Powershot S3IS) takes a barrel for lens attachments, so I used that to mount the ring. Simple friction fit. It can still take filters and lenses and the like.
The LED rings need a 12v power supply, which I got from an old, non-functioning DSL modem. I also desoldered the power jack from the PCB, CA'd it to the back of the wooden ring and soldered the LED ring wires to the lugs.
With no diffusion the LEDs show up as points of light. A piece of paper held over the ring doesn't do much to change that...
...but held a short distance away it does a nice job. I'll probably make another ring to hold a diffuser. Of course I'll cut the center out silly! Oh, there's a color difference between the two LED rings, which is pretty clear to see in these photos. Not ideal, but workable.
A couple of test photos. The first one looks a bit surreal, like it's been photoshopped, but it hasn't. The white balance was on the wrong setting though.
Cat hair? Really? I swear it gets everywhere.
Anyhoo, I've got to work on my camera technique but I'm pretty happy with how the ring light working.

Sanding boards
In my pursuit of making wooden jewelry I've been doing a lot of sanding. To make my life a bit easier I made some sanding boards today. They're just scrap pieces of flooring with sandpaper glue-sticked to them, and sheet cork white-glued to their bottoms so that they stay put on my worktable. The grits go from 150 to 1200. After 1200 I like to use micro-mesh pads to really polish the wood, those go up to 12000.
I also used another piece of scrap wood to make a sanding puck. The cork glued to it holds the piece I'm sanding so that I can apply even pressure to it, and it also saves my fingertips a bit.

Wood and silver...
I've been spending a fair amount of time working on various jewelry designs and workflows (I do love my workflows) using wood and silver. Here's something I made for my partner not too long ago. It's walnut and maple sanded to 12000 grit (overkill maybe, but hey) with a 100% tung oil finish (about 10 applications) and argentium sterling silver. I fabricated the bail myself as well.
It's a 45 record adaptor, in case you didn't know. I like how it came out. There's something in me that wants to craft small, beautiful things, beyond the simplicity of the buttons. I often think of it as moving atoms around.
