Tappers, 1998, aluminum, solenoid, steel, plastic. Pictured is one of seven tappers that I made Using a CNC mill, bending form, laser cutter and a variety of hand tools.

1998, aluminum. Early prototype for Tappers made using a three axis CNC mill. I designed the part using Solid Works. I did not make the final Tappers in this style because of the long machining time required to cut the curved surfaces.

Adaptive Lock, 1997, plastic, foam, lock, and key. The black plastic parts were machined using a CNC mill. The blue part is structural foam, which I shaped using hand tools. The first two images show a rotatable lever assist which is trapped in the oval base. I turned the rotational interlocking parts on a lathe before cutting them on the mill.

Coat Rack, 1998, bronze & cheery wood. Three Kinds of Casting: First I went to a Chinese grocer and bought a whole chicken foot which I cast into a polyurethan block. Without air, the foot did not rot, and I could replicate it in modeling clay at my leisure. (I recently found several chicken toes I had cast in the same fashion, they look unchanged after almost 20 years - cool and yucky). From the clay positive, I made a silicone RTV negative and from that cast four wax positives. After giving each a unique toe expression, I attached sprues and vents to the wax positives and set them in plaster. I used the standard "lost wax" process - burning out the wax and filling the plaster cavity with molten bronze.  After many hours of finishing the bronze, I machined mounting holes into the flanges. I routered a bevel on the edges of a cherry plank, sanded it, sealed it with clear shellac and attached the feet with brass wood screws. This coat rack has performed beautifully during almost 20 years of active use.

Caged, 1997, bronze & butterfly wing. Two pieces made free-hand in wax. I cast them using the lost wax process. 

5
Parts, 2012, bronze. These are parts (8 arms and 1 nose) arranged for the photo.  I made the waxes and sent them out to be cast.

Cups and Cones, 1996,  steel & gathered tree spikes. I made the cups and cones using metal forming. 

3
Moth, 1996, steel, hair, and candle. The candle shield is metal formed. I brazed the supporting rod onto the shield and mounting plate.

Bitsypic, Bitsypic Delux, and Bitsypic Tablet 2015-6, Baltic birch plywood. See some pics in the Bitsypic Gallery and see more on its Instagram account.

Waft and Wave from Emote Series, 1999, acrylic, steel, glass, motor. 

1
Competition Robot, 1998, electronics, various other materials. Working with my team, I built and programmed an autonomous maze-running robot for the culminating ME218 smart products course taught by Ed Carryer. 

2
iTonk, 2016, electronics, toy, iPhone. I modified a construction toy for very remote control. A person video conferencing the toy's phone can go forward, backward, lift the front loader, and make construction sounds by shining a small light into their phone's camera different directions.  Sensors attached to the phone's face pick up the light change and signal the toy to respond. The person controlling the toy can see where they are going through the toy's phone.

Tappers, 1998, aluminum, aluminum, solenoid, steel, plastic, electronics. These tappers were mounted in an atrium, each hit a material with a different sound. The percussion of each was controlled by a key word searched for on various internet news sites. This hour's amount of "war," "famine," "happiness," "relief," "weather," "justice," and "truth"  was sung, giving an intuitive sense of the world. I worked with a CS student to make an interface. He programmed the Java code and passed bytes to my programmed PIC which sent control pulses to the tappers. 

4
Emotes this one is called Draw, 1999, various materials, motors, electronics. I wanted to get more human kinetic communication from the computer. Each Emote has an action and purpose, and each is controlled by a remote loved-one using a simple motion based on-screen interface. The computer output specific input dependent bytes that I then translated into actions using a PIC processor. 

5
Spray, 1996, steel, hairspray, lighter, solenoid, concrete. I made eight of these flame throwers, each crowned a 6' tall steel and concrete stand, and was arranged in a semi-circle. I programmed a PIC processor to fire them in an orchestrated concert. You can't hear the burning sound in the photo, but it was fantastic. Inspired by the syncopated fountains made by Stanford alum Mark Fuller at WET.

Sea Bag, 1997, latex, valves.

Wheeswing and carrying bag, 2014, canvas, steel, plastic, webbing, nylon. I designed and produced a small run of take-anywhere, adventure swings. With its rock-pockets for weighting the throw line, and no-knot wrapping attachment system, it is easy to put up and easy to take down. Huge Thanks to Tae Kim of Alite for sewing and design advice.  Wheeswing photos by Jan Sturmann

Grittiegrip, 2015, webbing, shock cord, velcro. I designed and produced this fort building toy prototype to be just the right length and spring for connecting branches, furring strips, or furniture. 

1,2,3
Spray, 1996, steel, hairspray, lighter, solenoid. I designed and fabricated spray using an arc welded steel, steel bender, and various hand tools. 

1,2,3
Camp Out Trailer, 2013, wood, various appliances. I designed and made this trailer for groups of tent campers camping rough.  The Camp Out Trailer smooths the experience with a kitchen, bathroom,  storage for fresh and black water, and lots of room for equipment including tables and chairs.

Bowl, 1996, layered popular. I turned this bowl on a wood lathe, a wonderful experience that I recommend everyone try.

I teach design thinking and, oddly enough, end up doing more learning than teaching. I've explained most of the what and why on the Engage Design page. 

Shops are as living as the care their community gives them. Cleaning machines, organizing tools, and refilling diminished fluid reservoirs and material supply cabinets makes tomorrow's work go faster and builds trust between the community and their tools. I have been honored to work in several living shops. These photos are from one of my favorites, the Stanford Product Realization Lab. At the PRL I fabricated work from 1996 to 1999, and taught the use of all tools and shop culture to students as a Shop TA. We were benevolently lead by two legends, Dave Beach and Craig Milroy.
