Project: Guerilla Art

The Guerilla Art Kit

Your task this week, should you choose to accept it, is to do everything in The Guerilla Art Kit (available at Amazon, Powells, SFMoma, and your local bookstore) by Keri Smith. Maybe doing everything is a little ambitious, but we exhort you to try these projects, or at least read the book.

We recently got a copy. We had to, since it had the subtitle “for fun, non-profit, and world domination.” Being in the world domination business ourselves, it’s important to know the competition. It turns out that she’s good. Very good.

Matt’s awesome chip desk

What does one do 434 discarded Itanium CPUs? Matt Tovey was inspired by our Chip Trivet, and used them to make this awesome computer desk.

   

The CPU modules were scrapped as the result of a supercomputer upgrade, and were presumably functional before having their heat sinks taken off– a herculean effort for that many CPUs! Matt says that the list price for the lot of chips was over US$800,000 in 2006 and that the desk contains about 2.8 TFLOPs of computing power, about the same
as 900 3.2GHz P4s.

Matt started with a plain desk, tiled in the CPUs, and added wooden edging and a beveled glass top. Nice work!

I just love the way that this desk looks. But it gives me an idea too– take it one step further, and what if it worked? You could use a single, giant PCB for the motherboard which sat underneath the glass surface of the desk. With that much area, you could fit in a lot of processing power. On the cheap (or moderately cheap), one could imagine instead filling the inside of a desk top with low-cost (even last-generation) PC motherboards to make a great looking beowulf cluster or render farm that doesn’t take up any desktop or rack-mount space.

Sadly, Matt’s page has moved on to the great /dev/null in the sky, but the mirror still shows some of the build photos.

Quiltbert: a Q*bert Quilt

Lap quilt

QuiltBert is based on the traditional tumbling blocks pattern and the video game Q*bert. It is a lap-sized quilt, ideal for hanging out on the couch playing vintage video games.

A while back, our junior mad scientist brought home a geometry / art assignment from school based on designing a quilt. The kids were given a small grid which they filled in with a pattern. They then rotated and copied the pattern several times into a larger grid. His design looked like it would be very complicated to make into a real quilt, with curved pieces, applique and embroidery all needed.

That started us all looking at quilt patterns so he could get an idea of what goes into making a quilt. When we found the “tumbling blocks” quilts which are made with rhombi the question came up as to whether anyone had ever made a Q*bert quilt.

Although there are many tumbling block quilts that are referred to as Q*bert quilts, we couldn’t find any genuine Q*bert quilts. We did find Tetris, Space Invaders, and Mario, Mario, Mario, and more Mario. Also the tangentially related but incredibly inspired Color Bars quilt. Clearly, someone needed to make a real Q*bert quilt.

Urban Art at Morrow’s Nut House

Toadstools

Nut HouseWhile wandering around San Francisco, we ran across Morrow’s Nut House. There were some very silly decorated walnuts in the window, but that’s not what caught my eye. I couldn’t take my eyes off of the toadstools just outside. These capped-off pipes had been painted red with white spots. Urban art at its finest! Of course, the name of the shop is pretty good, too. Unfortunately for us, it was closed. Next time. In the meantime, you’ve got to check out the reviews people have written about this place!

Humane population control for feral golf balls

Natural environment
One of our neighbors is retired and, so far as we can tell, spends approximately twelve hours per day golfing. Golfing from his front lawn, that is. While he’s an agreeable fellow and we will not begin to question the motives or reason of someone that has this compulsion, we will simply observe that our neighborhood has an infestation of foam practice golf balls.

Beyond the many hundreds of balls that are successfully reclaimed each day, some dozens accumulate in the yards, bushes and hanging potted plants of our house and the houses of our other neighbors. They get stuck in the trees and bushes, confusing us when we go to pick lemons. People remember to shut the windows of their cars when they park. Sometimes it gets so bad they clog the gutters. You can even find them in places that they could have only gotten to after three reflections, leaving you quite puzzled. But, you get the idea.

Once behind a fence, they seem to have particular trouble getting out. (Especially if there’s a dog.) Case in point: This weekend we were at one of our (non-golfing) neighbors houses for a birthday barbecue. In the back yard, down below the little bushes, approximately twenty yellow balls were visible. I didn’t look hard; these were just the ones in plain view. When I pointed them out to our hosts, I learned that they had already thrown the day’s catch (a few dozen balls) back over the fence.

What do do? We decided to practice a humane method of dealing with pests: catch, tag and release.

The whole bandMany of the partygoers got involved in the process. Most of the balls were tagged with simple designs, but some were quite elaborate. We particularly liked this set (which we didn’t make), showing four foam balls as members of Kiss. We tossed them over the fence, and they disappeared early in the morning. We’re waiting to see if any of the tagged ones reinfest the yard, or if we get new ones every day.

If our golfing neighbor is sufficiently annoyed by people writing on his little foam balls, it may even be effective as a means of population control.

 

Maker Faire Bay Area 2007 was fantastic!

Kill your television and make stuff!Maker Faire was a smashing success. The big message of the fair was summarized succinctly and stamped on the back of a card we were given: “Kill Your Television and Make Stuff!”

We had a great time in our little prototyping world off in the corner of the Expo hall by SRL. Near us Bathsheba Grossman had her beautiful sculptures, Fab@Home was printing with cheese and frosting, John Guy had his 3D CNC gantry next to his margarita machine, and Lee Krasnow had an entire workshop for his precision puzzle making. We were also by a couple of exhibitors (as opposed to makers): Epilog and Protopulsion, but I have to say, it seemed like the makers all got a lot more traffic than the corporate folks with their tradeshow-style setups. We were all off behind the Tesla coils, which stole our visitors’ attention hourly. Nobody could compete with the Tesla coils when they were running!

We can’t possibly list all of the cool things we saw, and we didn’t see half of the stuff there, but read on for some of the highlights for us.

A few more sugar sculptures

Sugar Soliton

This is a rendering of the sculpture Soliton by Bathsheba Grossman, as output by the CandyFab 4000; it’s a three-dimensional form made out of pure sugar. Seeing Bathsheba’s sculptures at the 2006 Maker Faire was the inspiration for us to build the machine in the first place, so it’s quite exciting to be able to print this. (The design is used by her kind permission– please buy some of her sculptures!)

This is our second try at fabbing this difficult shape. Our first attempt was at a somewhat smaller size and ran into trouble with the thin beams when *one* of our thin horizontal layers turned out to be too weakly bonded. To avoid a second failure, we enlarged the model but also ran the heater element very hot and for an extended period of time to make the pixels srong, but also larger, more rounded, and richer in color– a darker caramel.

In this view we’re looking right down at the printed layers of sugar; we think that the grain of the layers makes this look a lot like a wood carving.

Of course, that’s not all that we’ve been printing this week. Here is one more large-scale object that we made:

mobius monster

The shape is a 3/4 twist mobius strip with a square cross section and windows cut at regular intervals in all of the sides the side. Even though it’s hollow, it still weighs seven pounds and fourteen ounces– that’s a lot of sugar. We’re bringing this monster to Maker Faire this weekend, so you can see it for yourself, too.

Solid freeform fabrication: DIY, on the cheap, and made of pure sugar

CandyFab Sign

In February we gave a sneak preview of our project to construct a home-built three dimensional fabricator. Our design goals were (1) a low cost design leveraging recycled components (2) large printable volume emphasized over high resolution, and (3) ability to use low-cost printing media including granulated sugar. We are extremely pleased to be able to report that it has been a success: Our three dimensional fabricator is now fully operational and we have used it to print several large, low-resolution, objects out of pure sugar.
