Laser Cutting Stuff - What Have I Been Up To?

I've been introduced to the wonderful world of laser cutting. Most of the stuff I design is for work, used in modular robotics. Every so often I find time to create something just for fun. I can't share all the photos until after Christmas because most of these are gifts and I don't want to ruin the surprise (not that anybody reads this anyway). But here one of the things I made:

It is based on the piece by Robert Indiana, and made of pine board.

Preparing for a very DIY holiday season is taking up all my free time, but there are some other things in the works, though it could take a very long time:

• New macro photography tools, as I continue to experiment with lenses, lighting, etc.
• A simple HDR algorithm, for photos where no info (exposure time, camera model) is given
• A few sewing projects

Check back later for lots of photos after the holiday season.

Lost Woods - Music Box

I got a music box for my (upcoming) birthday. Seven hours later, and this was done...

Things I learned:

No accidentals (must be in the key of C and free of any sharps or flats).

You can't play a note and the note directly above it because the hole punches are too close.

You can't play the same note in rapid succession (on adjacent lines on the grid's 'time' axis).

Now I really want a music box that can play half steps, can play notes in more rapid succession, and isn't so squeaky.
