The Aluminum Velociraptor

The Aluminum Velociraptor

I’m not an expert on dinosaurs, but the velociraptor is one of the more respected of their ilk (so I am told) and you really do have to respect such a clever girl properly, so I grabbed this velociraptor silhouette from OpenClipArt knowing that I’d find a use for it some day…

Sculpture from Melted Vinyl Records

Sculpture from Melted Vinyl Records

Jonathan Hudson is an artist who specializes in recycled materials. “Girl Put Your Records On” is a female form sculpted from vinyl records. From his site:

Educated in the field of science I am constantly experimenting and exploring new approaches to my subject matter. My intentions are to create well-crafted works of art that visually speak to the viewer and evoke an emotional response. When possible I try to use recycled materials and repurpose them for something other than a landfill. As a Biologist it is disturbing to note the rate of devastation our species is inflicting on our planet. Recycled/Repurposed Art is at least one step in the right direction.

Multi-Touch DJ Light Table

Now, I know there will be some die hard vinyl-philes out there prone to fussing about the lost connection of tactile feedback or the degree of skill required to match turntable beats. But lets face it, all practices evolve, music being no exception, and the Multi-Touch Light Table is such a thoughtfully conceived and artfully crafted piece of UI that even the analog evangelists won’t be able to deny its merits.

Recently, we are working in class on a variation of the Rock and Roll Speakers from Fashioning Technology. Rather than using perfboard for the circuit, we’ll be burning our own circuit board. The chips are through hole LM386’s, but I don’t think it is realistic to have the students drill 8 aligned holes on the circuit board. There is an excellent primer on printed circuit board etching in MAKE, Volume 02. After thinking this through a bit, I came up with an idea to turn the through-hole component into a smd component. The technique is a bit like the design of the Broadcast Your Podcast FM transmitter circuit, which just has you solder the components together in pools of solder on chips of board.

When the chips finally arrived from Electronic Goldmine, I looked up the datasheet for the LM386 to get the measurements. In Open Office Draw, I drew out a design that would match up with the pins. With the help of Pat, who is doing an independent study on CNC tools this year, I sent the file to the machine with the vinyl cutter. He cut the file, then we weeded it to see if it matched the chip. The file matched the pin locations of the chip, so we made a few more iterations to get the process down and the layout right. When we got it right, we cut three copies of the file for boardmaking.
