Here’s the same thing as the last post, but the least-cloudy pixels over a month of mornings, June 2012.

The Moderate-resolution Imaging Spectroradiometer (MODIS) is a camera on board the Terra satellite in sun-synchronous orbit, launched in 1999.

This is what all of the available Terra images marked with today’s date in the MODIS browser look like when stitched together, with pink representing non-values.

I made this using Charlie Loyd’s wheather app, which I’ve been hacking at over the last few days.

Piotr Kamler – Une Mission Ephémère (1993)

July 1st, 2012

An explicit examination of interaction, from Polish animator Piotr Kamler — this is a reprise of many of the themes of his earlier work since the 1970s, going so far as to reuse models from his 1982 opus Chronopolis.

It certainly recalls very accurately the sense of whimsical vertigo seen in late 70s and early 80s illustration, as particularly exemplified by Moebius, La Planète Sauvage, and their ilk — the horror of interface design. Charming-looking mechanisms with coy personalities are always in danger of reacting poorly to manipulation, rising up in Lovecraftian ways and overwhelming the user. I suppose it all boils down to drugs and the Other eventually.

Thing 008: Miniature Queen Anne Wingback Chair

February 25th, 2012

Miniature Queen Anne Wingback Chair, on Thingiverse from PrettySmallThings, a “scenic designer in the theatre industry” in Astoria, NY. Printed in 33 minutes.

This may be the perfect object. It’s 1 1/2″ tall, and is the spitting image of my long-lost beloved reading chair, what I done rescued from a sidewalk in Boston twelve years ago. Pale blue velveteen she was, and a reproduction from Medford. But I loveded her.

Thing 007: Adorable Elephant

February 10th, 2012

an adorable stylized elephant.

My evil nemesis dared me to attempt to print this adorable elephant he’s selling in full-color sandstone over on Shapeways. It printed out the size of my thumb in 18 minutes, in a single translucent layer.

He snatched it from the build platform while it was still warm and ran off into the night cooing at it before I had the chance to trim the fuzz from its adorable trunk.

*Snatched* it.

Thing 006: MakerBot Astronaut

February 6th, 2012

This MakerBot Astronaut passes the play test: when you pick it up, you want to make it walk around on the nearest head, claiming said head for Earth in a comical astronaut voice.

My longest and most complex build yet. At the default size it’s four inches tall, and prints in five pieces, in the following times:

  • head: 11 minutes
  • helmet: 21 minutes
  • arms: 24 minutes
  • legs: 25 minutes
  • body: 44 minutes

Total: right around two hours. Then, giddy with the power of blue painter’s tape, I printed another, all on one raft.

To my surprise, this took slightly longer: 2 hours 10 minutes, I believe because of the overhead in moving between pieces on the same layer, and because the support settings are all or nothing: I needed support for the helmet, but I got it for every piece on the raft, spending unnecessary time and plastic.

So the moral is: if you’re doing a lot of pieces, or a multi-piece object, slice the objects separately and combine the G-code in a text editor if you can; it’s faster. And there’s another benefit to splitting the builds: if something goes wrong, you don’t have to re-build the whole thing.

Thing 005: Shower Curtain Hook

Total time elapsed from opening SketchUp to holding the printed object in my hand: 15 minutes.

Thing 004: Stellated Octahedron

February 1st, 2012

The stellated octahedron (octangula stellata) is a shy and noble beast, named by Kepler, kept by Escher, and very difficult to trap intact. My previous attempts had, until today, all ended in gruesome failure:

It was not until the addition of blue painter’s tape to the mechanism that I was able to witness the creature’s complete apparition. The tape’s increased surface area allowed the spritely form to adhere more fervently to the MakerBot’s reification plane, preventing the unavoidable throes of creation from dislodging its grip on our reality prematurely.

All MakerBots should ship with blue painter’s tape.

Thing 003: Fan Attachment

January 30th, 2012

Update: This is now Thing #16842 on Thingiverse!

The MakerBot works by melting plastic. Two kinds are most commonly used: one is made from corn, and reportedly smells like waffles when heated. The other is called ABS and smells like a styrofoam cup on fire. This is of course what I’m using.

In the concentrated atmosphere of my windowless subterranean lab, the smell (of the plastic) rapidly causes me headaches. So I found an old computer fan, got a length of flexible 3-inch hose, and designed a fitting in SketchUp so I could vent the smell away to the surface.

This fitting is nearly the width of the MakerBot’s build platform, and when I ran a test build, the outline of the foundation layer (known as the “raft”) was too large for the surface, and the nozzle kept hitting the platform’s outer limits. Adjusting the settings, generating new build code (known as “G-code”) and setting off another build was costing a lot of time and plastic.

That’s when I went looking for a G-code visualizer, and found ProcessingGcodeViewer, a standalone Processing app written by a MakerBot intern. It lets me check the path computed by the model slicer before I send it to the MakerBot for building.

Useful, free, *and* it looks like an Iron Man interface. And with the hose attached and the sides of the MakerBot closed up, the odor is nearly eliminated, and the mad-scientist aura of the lab is increased significantly.

Thing 002: Portal Cake

January 28th, 2012

The 19th was my birthday! As befitting my station I commanded my MakerBot to make me the cake from Portal.

It imported into ReplicatorG at 1cm across, which it printed in under a minute. You can see just a hint of cherries, but the resolution was too small for more than a tiny stump of candle. It left the doily off entirely.

I doubled the scale to 2cm, which including a raft took about 10 minutes.

I redoubled it to 4cm across, which took about 40 minutes and almost failed: a draft caused the left side to curl up, threatening to detach the raft from the build platform, leading to certain doom. Heedless of my own safety and mocking Death itself I leapt into the maw of the MakerBot and secured the cake to the build platform with a piece of tape. It finished, complete with candle, and my birthday was saved.

By my very rough estimate it’s about a 50-layer cake. Take that, southern grandmas I read about in the Times.

Thing 001: Calibration Cube

January 26th, 2012

My first print! It’s not really a cube. It’s the 20mm calibration box, but from above it looks like a cube, and the alliteration is nigh-impossible to resist.

The hexagonal infill pattern makes it look like a pat of butter fabbed by MakerBees.

Tradition dictates that one inaugurate one’s MakerBot with a commemorative saying upon the initiation of its first print. While the suggested phrase — “Fire the MakerBot!” — has many attractive qualities, when the time came I was feeling nostalgically geeky, and for those reasons chose “Make it so” with a Patrick Stewart/Sean Connery conflection* and a concomitant “Engage” gesture to make sure it knew I was serious.

It worked pretty well. My cube came out very slightly squashed on the bottom, which I understand means either the build platform was too warm or my gesture was too fast.
