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.

Fine print on the Bawls box

Bawls 1   Bawls 2

Bawls3

We are great fans of Bawls Mints. Or, I should say, we were great fans of Bawls mints, because they are apparently no longer being made. They have been replaced by this visually similar but radically inferior substitute called “Bawls Buzz.” The formula has been completely reworked, and now tastes of cheap, bland candy, a little bit like pixy stix. Sugar is no longer the first ingredient.

On the other hand, the text on the bottom of the box is still there and still brilliant. Who makes packaging like this anymore? (And who makes candy like Bawls Mints anymore?)

Photomask coasters

Coaster

Photolithographic masks, or photomasks are clear templates used in semiconductor manufacturing. Typically, they are made of UV-grade fused silica and have a highly intricate chrome metal film pattern on one side. These remarkable objects are exactly the sort of wonderful thing that occasionally pops up at good electronics surplus stores. We recently found a few, took some pictures (see below) and, in the spirit of re-use, made them into some classy coasters.

CandyFab @ Dorkbot: 8/15/07 @ TechShop

symmetric view 2

On Wednesday, August 15 we’ll be giving a presentation about CandyFab at a meeting of Dorkbot SF, our local spinoff of
Dorkbot NYC.

Dorkbot chapters organize monthly talks and events for artists, scientists, and engineers centered around the theme of “the creative use of electricity.”

The meeting will be held at 7:30 PM at TechShop, a San Francisco Bay Area “open-access public workshop,” located just off of 101 in Menlo Park, where you can go use a wide range of tools and machines to make things. We’ll be bringing the CandyFab machine along, and– if everything goes right– demonstrating its use. So if you’re in the SF bay area, this is a great chance to come and take a close look at the CandyFab 4000, smell the caramel, and ask questions. Besides our talk and demo, there will be a couple of shorter presentations on other dorkbot-ish topics, and an introduction to TechShop. (Tours of Techshop will be available at the end of the meeting as well.)

Everyone is welcome to come to the meeting; there is a $5 suggested donation for the venue at the door.

UPDATE: The event was great! (Read more here.)

More circuitry snacks

My old friend Kevin sent in these pictures of a massive array of tasty electronic treats that he and his family made for a group picnic at Los Alamos National Laboratory. (Nice work!) If your diet is short on precision op-amps and instrumentation amplifiers, these just might hit the spot.

You can read our own article about circuitry snacks (dated July 11, 2007) here.

One minute project: Bike tube rubber bands

Patch  Set of bands

Once a bike tube needs its (n+1)th repair, where nis the number of times you’re willing to fix it, you can slice up what remains, and end up with a semi-infinite stash of cool looking rubber bands.

Useful? Yup. Cheap? You bet. Quick? Yes, to the point of being trivial.
On the other hand, not only is this a fun way to recycle, but using these is the office supplies equivalent of the secret biker’s handshake– only other bikers will even notice what you’re using.

Printing complex shapes: A sugar chain

Sugar Chain We made this chain of twelve giant links on the CandyFab 4000 to demonstrate the fabrication of a complex object, the sort that is difficult to make by conventional machining processes. You can see the 3D model and some build pictures for this monstrosity over at CandyFab.org.

This object also highlights the relatively large build envelope of the CandyFab– significantly larger than that of most other low end (i.e., under $50k) 3D fabrication systems.

PS for Chemistry geeks: insert joke about long-chain hydrocarbons here.

 

Webcast links

We got all packed up and headed out to the Exploratorium today for the Maker Webcast about 3D Fabrication in sugar. Thanks to Dale Dougherty from Make Magazine for inviting us – we had a great time! In case you missed it, here are the links to the archived show on the Exploratorium website: mp4, real player, windows media. (If in doubt, try the mp4 version!)
