Made by Hand: Searching for Meaning in a Throwaway World

on May 31, 2010 in Making

Made by HandMemorial Day weekend is a good time to catch up on reading, so I picked up this DIY manifesto by MAKE editor and Boing-Boing founder Mark Frauenfelder. It was an easy and pleasurable read.

The book starts off dramatically with the author’s decision to move his family to a South Pacific island. He quickly learns, along with anyone who has ever read The Sex Lives of Cannibals, that these islands are third-world countries with rusted buildings and sub-standard medical care. He moves back within four months. He decides to find another path to a meaningful life — one that will still allow him the comforts of U.S. suburbia.

His solution to this problem was to explore ways of making his own food and tools and educational experiences for his kids. The book repeats a pattern for most of this: he finds a really interesting person who is living at the extreme, documents their lifestyle, then takes a more moderate approach himself. As with the island excursion, he is willing to try some truly unusual projects, which mostly don’t last. This makes the book accessible for people for me who are never going to give up going to the supermarket, but still want to enjoy the satisfaction of making. And as such, he reaches some of the same compromises. No, we won’t homeschool our kids, yes we will supplement a standard school education with hand-on projects.

I have never tried to formalize my reasons for creating things. Intellectual stimulation, building new competencies, and feeling more control over the physical environment are certainly part of it. And if you are very lucky, you end up with something beautiful or entertaining. Whether one can fully claim that meaning is being added to the world, I don’t know. Unless one is fully dedicated to recycling, you will still end up buying parts and tools and driving to Home Depot. I am fully aware that I am still a consumer. No question though that it can be very satisfying.

Frauenfelder notes that the amateur science movement suffered a blow when personal computers were invented; many of the people who might have done science or DIY gravitated to this new platform. But as computers and the web have matured, many people are tiring of living a fully virtual world and want to make something tangible. I believe this is correct. I’ve certainly experienced this feeling myself, and have heard many IT colleagues and academicians say similar things. Part of me wonders, though, if this too will be a phase. Frauenfelder has shown himself to be a genius at finding trends and was a key part of the Internet bubble. According to the book he has moved into DIY for the last 18 months — not long. Will whittling spoons still be meaningful ten years later, or will it seem a poor use of time?

Ironically for a book that celebrates handcrafted objects, I experienced it in virtual form. I alternated between my Kindle and the Kindle App for the Blackberry. They both performed admirably. I had never really used the Kindle App for the Blackberry before. Since my Blackberry goes everywhere with me, and has a backlight for nighttime reading, this means I will never be away from a vast library. That is both an exciting and daunting prospect. It is yet another opportunity for the virtual world to overwhelm the real one.

Potato batteries

on May 24, 2010 in Electronics, Making

  Laurel went through a rite of passage last week, her first science fair. This was a non-competitive event, an Arts and Technology Night organized by her school. She really wanted to exhibit something so we got her signed up. After looking online for ideas, Laurel chose to do food batteries. Batteries are very simple […]

Playing with a solar robot

on May 18, 2010 in Electronics, Making

Holly has been begging to build her own robot ever since I made Robie. Fortunately there are some excellent options for kid-friendly robot kits. After browsing the MakerShed we decided to get the 6-in-1 Educational Solar Robotic Kit. This was a good choice. As the box states you can make six different robots. We’ve done […]

More toys for the workshop

on May 17, 2010 in Making

During my robot build, I was constantly wishing for a drill press. I put off purchasing one because I couldn’t decide if I really needed a full-sized press, where to put it, etc. I eventually stumbled on a drill press that is small enough to fit on (or be stored under) my worktable, but has enough […]

Automating Windows

on May 13, 2010 in Web and Computer

I have a great job (read: limited hours, excellent pay) but one of things I like least about it are the repetitive IT tasks I have to do. Things are stable enough that a full sysadmin would be a waste of money, but still, certain things have to get done. For a long time I […]

Robie the Robot lives!

on May 9, 2010 in Making

A few days ago I put in the obstacle avoidance programming for the coasterbot. Almost immediately, he acquired a real personality. The algorithm works incredibly well. Even though the first version of my code had significant bugs — typos, forgetting that moving the sensor servo takes a finite amount of time, etc. — he was […]

Coasterbot gets a pair of eyes

on May 2, 2010 in Electronics, Making

I was featured in MAKE Robot Dispatch #7 — thanks guys! Hard to believe that there is less than a week left in the contest. One of the requirements of the contest is for the robot to do some obstacle avoidance. The Jameco bundle came with some switches to do bump sensing. While this might […]

Coasterbot moves!

on Apr 26, 2010 in Electronics, Making

With the electronics done, it was time to go back and work on the chassis. As before, the DVDs are linked with screws. I wanted the servos to be firmly attached. Since we removed the controller units, this left a lot of empty space in the case, allowing for this type of attachment: I still […]

Robot Fest 2010

on Apr 25, 2010 in Making

Today the family and I went to Robot Fest, held at the National Electronics Museum. I had been looking forward to this for a long time, and I wasn’t disappointed. There were any number of fun displays and workshops, including in no particular order: compressed-air rocket launches, Lego robots to control and build, a vocoder […]

A nice coasterbot surprise

on Apr 20, 2010 in Making, Web and Computer

This morning, I got an e-mail from YouTube asking me to sign up for revenue sharing on my “popular video” of coasterbot folding. I didn’t think too much about this, because that was a 10 second video I shot one-handed. I hadn’t even bothered adding an audio track, or a link back here. The only […]
