Maker Faire KC Part 1: Printing Technology





Is this IBM Selectric II cool, or what?  The maker grew bored with it and created a printer with the judicious use of programming, solenoids and cables.  This maker collective, the Cowtown Computer Congress, had a bunch of projects on display and this was a big attention getter. 


I assumed wrongly that the interface between the laptop and the typewriter was probably something Arduino.  Nope.  This guy etched his own circuit board!

Typewriter art, anyone?  I could watch something like this for hours. Did you notice how much the ribbon cartridge and ball head look like a robot?  Claire and I see robots everywhere.


To see this beast in action and a comprehensive build diary, visit http://www.robotdialogs.com/2012/06/typomatic-part-3.html  The Cowtown Computer Congress is one of many hacker spaces that has emerged over the last few years.  Makers share a space and major equipment with regular build nights and special events.  A hacker space is a big playground for adults.  Check around, there may be one in your town!


The Print Factory

My favorite entry in the traditional print department is the traveling crew from The Print Factory.  They are printmaking evangelists and show up at regional events with great lino and woodcuts ready to ink and press.  From experience, I can tell you this is just as enjoyable for adults as it is for kids.



Such pretty ink.  To see more about The Print Factory, visit http://craftandconcept.com/


Maker Bot

Maker Faire would be pretty awesome without 3-D printers, but it wouldn't be the same.  The Maker Bot crew was out in full force introducing people to the joys of home printing.  The Maker Bot Replicator now has a dual extrusion print head... and a bunch of new competition.  Their goal was to democratize the act of making and they spawned a new industry using true open source hardware and software.  The competition is coming for around $600 as a home printer, but they may not be as dedicated to open source.

Other than the metal bits and servos, these remote control Minions came off a Maker Bot.  The drawings, like everything else in Maker Bot world, are available on the Thingiverse.


Kids love watching Maker Bots in action as much as I do.  It used to be that only elite schools and businesses had access to 3-D printing for prototyping and small run items.  Not so long ago, the technology would have set you back over $10,000.  The previous version of the Maker Bot ran around $1,400 and the new Replicator runs around $1,800. 

One of the best things about 3-D printing:  makers use them to build parts to make larger and more elaborate home brew printers.  There were at least a dozen custom machines spread out around the Faire.


On the subject of democratizing 3-D printing, a number of libraries have installed Maker Bots.  Imagine a future in which you could print any widget available on the Thingiverse or something you throw together on Google Sketchup with a library card and a few cents for materials.  Do you need a replacement knob for a Hermes?  Print on demand is cool.

Check out this set of wings produced by another member of the Cowtown Computer Congress.  The gears were custom printed on a first generation machine.


Last year, the Kansas City Maker Faire filled this hall with some outside overflow.  This year, they shut down a street in front of Union Station for the Arc Attack tent, Power Wheels, vendors, exhibitors and custom cars.  That was in addition to three extra rooms inside the station. Sweet.

Canon 7D Survival Test

The nice people at DigitalRev TV are a little crazy.  But they are crazy in an entertaining way.  In this video, Kai puts a Canon 7D through a series of torture tests.  Can this DSLR survive being hit with a truck, immersed and frozen, shot, thawed and burned?

I'm not going to give away the ending.  However, I probably don't need to coddle my 60D as much after watching this test.


I have to admit that this was pretty excessive.  I would not try this with my own camera.  I certainly wouldn't go quite as far over the top as Kai. I'm not quite that childish.

Even with all that, I am reminded of the photojournalist who died in the collapse of one of the World Trade Center towers.  His Canon DSLR was found smashed in the rubble.  While the camera was well beyond the point of ever functioning again, the files on the CF card could still be retrieved.  I'm impressed with how far imaging technology has come.

Nelson-Atkins World's Fairs Exhibit Opening



Margo would love a visit at Meet Margo: The Gold Royal with Star(let) Power

Entertainment for the evening.  Sadly, there was a conspicuous lack of mimes.

Photography is not allowed in the exhibit due to the number of pieces on loan from other galleries and private collections.  Visit the website for more:
 http://www.nelson-atkins.org/art/exhibitions/worldsfairs/bells-whistles.html
http://www.nelson-atkins.org/art/exhibitions/worldsfairs/exhibition-themes.html

This is a major exhibit with many special programs and educational tie ins through its run.  Skim the website and you'll get a good idea of the treasures that await.  Our favorite part was the transition from Art Nouveau  to Art Deco.  Margo's designer, Henry Dreyfuss, even built a model city, "The Democracity", for the 1939 New York World's Fair.

In keeping with the tradition of the World's Fairs, the Nelson-Atkins decided to house a temporary structure showcasing technology and design.  After an open competition, the Sun Pavilion was born.  It lives on the lawn just past the sculpture garden.


The structure is comprised of reused scaffold support parts and old cargo containers.  It is interactive.  Visitors can donate various bits of debris which artists will turn into new art.  The solar panel array is functional and connected to a power management system so visitors can learn about the mechanics of taking DC and making it into AC.

Here is the official description from the museum website:
In conjunction with Inventing the Modern World: Decorative Arts at the World’s Fairs, 1851–1939, The Nelson-Atkins Museum of Art is proud to present the Sun Pavilion. World’s fairs were the most important vehicle for debuting technological and stylistic advancements for functional objects and the pavilions that housed them. The Sun Pavilion is a temporary structure keeping with these important themes. The design and construction team for the Sun Pavilion includes Generator Studio, Tm Gratkowski, Brightergy LLC, Thornton Tomasetti, BC Engineers and Prosser Wilbert Construction. The Sun Pavilion will be a sophisticated and visually compelling mixture of architecture, design, and technology. The open and fragmented array of solar panels, scaffolding and interior spaces will create an exterior connection to the featured exhibition in the Bloch Building and provide interactive experiences on the museum campus. Visitors of all ages will experience progressive principles of contemporary design and technology in this exciting new space.

The Birthday Blog Post From Space


March, 1964 was a good month.  But I am perhaps a bit biased.

For anyone that has been following this blog, it is no secret that I have a serious love of anything related to space exploration.  It's my birthday and I am going to totally date myself by posting National Geographic images from the month I was born.  I can't think about my birthday without thinking of growing up during the space race.

The excitement of space travel and technology development was the flip side to growing up with the Vietnam War, the Cold War, duck and cover, and its close cousin Mutually Assured Destruction.  I grew up in an era where all of this was shiny and new.  Everything smelled like the future.  Well, except for cars before emission controls.

This has an interesting resemblance to the 1954 kids book version of the the space suit.

This is something of a hybrid between the Soviet and U.S. approach to landing.  Interesting concept, but probably just as well that was all the idea amounted to.

I am still amazed by rockets.


This was actually at the beginning of the article.  The article contains a detailed foldout of the various pieces of Apollo space craft.  The LEM was pretty well thought out five years before we actually got to the moon.
Coming home.  Really, the whole thing is just amazing.
It's funny that I still think of us getting to the moon in terms of "we" and "us".  Certainly, there is some national pride and I would not have wanted the Soviets to get there first.  But I tend to think of actually getting there as an accomplishment for our species.

As much appeal as I find in human space travel, I am still excited by our collective activities in space exploration.  Four years into the Great Recession, it is hard to comprehend the amount of money it would take to lift people and all the stuff they would require to Mars. From my perspective, we need some really good targets before we take the next steps.

We are doing some incredibly good science between our robotic and remote sensing servants. As of March 19, 2012, we have collectively cataloged 762 extrasolar planets including one water world.  Just this week, we learned that Mercury is a really strange place. NASA Messenger Findings

Although our family mourned the loss of the Mars rover Spirit, Opportunity is beginning its ninth year of its three month mission.  Its much larger cousin, Curiosity, is in route to Mars loaded with a comprehensive laboratory tools.  Curiosity won't be dependent on solar power.  We'll see what lessons have been learned on reliability in design.

Although the NASA shuttle program is no more, the International Space Station has been continuously inhabited for over 12 years and zips by overhead every 90 minutes or so.  The U.S. crew members are licensed amateur radio operators.  Beyond having access to high powered transmitters for remote control quadrotors, talking with the ISS crew is the coolest thing I can do with my new FCC Technician license.

Granted, my kids have a space cheerleader at home and friends bound to be future software, computer and robotics engineers.  Although human space flight is a big deal for them, they are equally excited about everything else going on in space research.  At some point we'll probably try out the crowd sourced SETI Live program. http://www.setilive.org/

For me, space is all about inspiration.  I'm thankful for the pioneering work that has gotten us this far.  I'm also excited for the future of space exploration.  When we decide to go, it will no doubt be to someplace incredibly interesting.  Maybe one of our emissaries will get to say hi to Spirit in person.

FIRST: A Day at the Kansas City Robotics Competition

Claire (aka: gingercat) loves showing off her swag.  This is the collection from an hour and a half in the pit area.  Teams swap and give goodies away.

One of the best things about FIRST is that competitions and the pit areas are free and open to the public.  As long as you are wearing safety glasses, you can wander around and talk to the teams about their robot designs.  The kids love to show off their bots.

A slice of life in the pits.

Tech inspection.  Robots are checked for weight and regulation equipment.
Before I go any further, I have to recommend my Spousal Unit's blog on the subject at 
http://housefullofnerds.blogspot.com/2012/03/robotics-competition-even-tech.html
She is not a techie and will approach this from a different perspective.

Moving on...

The work doesn't stop with building robots.  Each assembly and sub assembly must be documented with CAD software.   The team has to build a website and create promotional materials.  Some of the teams go all out doing community outreach programs as well as promoting STEM to girls.  The latter is important given the number of engineers and designers we need to have this be a country of makers.

OK, that's enough of the semi-political advocacy for my girls.  Now we are ready to rumble!

You might want to watch the overview video at FIRST Rebound Rumble Animation on Youtube

A FIRST round always starts with an autonomous task with plenty of points to be grabbed.  The robots are programmed and loaded with sensors.  This year, they had to navigate into position and shoots baskets without hairless ape intervention (except for the little used Kinnect option).

The real action starts during the driver phase.  Each robot typically has two drivers and someone watching the clock and the field.  Microsoft donated Kinect systems to FIRST this year.  One of the regional teams opted to use one for hybrid control of the robot during the autonomous phase.


The parts kit includes the same batteries, PLC and I/O system.  Some of the motors are standardized as well.  There is a weight limit and a parts cost limit of $3,500.

This was a unique design and was foolproof as long as no opposing robot ran bumping interference.  That is legal in certain zones in the field.

Here is the amazing thing:  Each team started with the same box of parts, rules and specifications to create a practice field.  From there, design diverges as each team prototypes and builds their robots in six weeks.  They then crate the bot and ship it.

Of course they don't do this alone.  There are teachers, sponsors and mentors.  We talked to one team mentor who mentioned that their school is just outside the gates to the Fermilab.  Yeah, that Fermilab; the one with the particle accelerator.


There were a few catapults and many driven wheel shooters.  Some had turrets that could be rotated as needed.  We saw many different ball grabbing designs.

On top of all the other engineering challenges, the balls were made of Nerf like material that degraded throughout the competition.  Hardness, texture and friction changed as they went along.

Can you believe that every one of these machines was designed and built by high schools students in six weeks?  Bear in mind that almost all of these kids are in AP heavy programs.  It's fair to say that the bell curve is skewed two or three standard deviations in the arena.


Engineering is serious work, but so is Gracious Professionalism.  Teams cooperate.  They share parts in the pits.  The kids spent six very long weeks building their bots and then live in the pits for almost three days.   They are competing for the same scholarship dollars.  For the most part, they are loving every minute of it.



More about Gracious Professionalism and its partner, Coopertition are found on the FIRST website at  http://www.usfirst.org/aboutus/gracious-professionalism


While the goal is to bring up the next generation of engineers, the teams are still in it to win.  This year there were two teams that absolutely dominated the field.  Here they are in a four minute pit stop between the semi-final and the final round.  That's just enough time to swap batteries and check all of the electrical connections.


Terror had two names this year.  Introducing the Bomb Squad and Team Titanium...


So now it is time to prep and shoot.




And shoot some more. 

To say that the Bomb Squad was a shooting machine would be somewhat redundant, but seeing an elegant design in action is inspiring.  Team Titanium was no slouch, either.  But I think that the Bomb Squad sucked up more balls and made more shots.


This was not the final round score, but you get the idea how this Red Alliance did overall.


We walk into Hale Arena each year to watch the regional competition and cheer on the local teams.  I remember the first time as I looked around and said "I smell nerd."  It's like being at home except a lot louder and with more and better technology.

Claire wants to go to the local high school that has an engineering program and a mature FIRST team that has been to the world championships twice.  If she chooses to follow through and makes the team, we'll miss her during the long, sleepless build weeks.  But we'll know she is in good company.
