I’m back in my studio after an amazing trip to Los Angeles. I miss that fabulous (sunny and warm) city, but wintertime rural Virginia is good place to get work done.

Piezo speaker housing /
Here's a prototype of a housing for a piezo speaker that I will actuate with analog electronic insect sounds. The shape of the housing and mechanical pressure on the piezo element will change the pitch as well as the volume. I made this housing by first laser cutting 1/4" acrylic and gluing the stacked rings to make a pyramidal-shaped buck — see images below. Note that there's a central hole all the way through the buck to aid the vacuum forming process. I’ve vacuum-formed .080” and .090" acrylic sheet over the buck (both work fine) and used a laser to cut the shapes out. My registration needs improvement, but you get the idea. The piezo element is mounted inside of the housing by a short length of plastic tube that I glued in place.
Below I show my process to cast the acrylic buck in plaster (using an alginate mold). I will use plaster, wood, or metal bucks in the future because acrylic deforms in the vacuum forming process. In either case, it is critical to use mold release.
Why am I doing this? Because when RadioShack went out of business, I could no longer buy the piezo speakers that I used for my insect sounds. I was forced to reverse engineer the part --which turned out to be a blessing because the sound of insects is heavily dependent upon the mechanics of speaker design (not just the electronics which drive the speaker).

"I'm on a Chip in the Clouds," 2017. Watercolor and acrylic on joined paper. 31" x 37"
Here's the story of how this crazy painting came to be. It was a rainy day, and so I started in my studio with a self-portrait in which I appeared to be daydreaming --hence the colors and thoughts around my head. At some point, the sun came out. I prefer to paint in the beautiful landscape that surrounds my home... so I joined additional paper to my canvas and went outside. Lost in my thoughts and distracted by my computer, I wasn't really present in the landscape. So I encapsulated myself on a computer chip that is floating in the clouds. And now, after all, my artwork has become a digital image file that I upload to the cloud.

Seeing /
I've been re-reading Carlos Castenada's incredible conversations with Don Juan and thinking a lot about *seeing.* I don't use drugs, so these paintings are sober studies from my landscape in rural Virginia. (Watercolor and acrylic on paper, 2017)
