For my second maker-oriented book, I read The Hardware Hacker by Andrew "bunnie" Huang, published by No Starch Press. You can find the podcast here (as a .wav file).
I give this book a solid 5/5 stars, two thumbs up, or whatever positive rating you'd like. I've been a bunnie fan since Hacking the Xbox (also from No Starch Press, and released for free in 2013 in honor of Aaron Swartz), and this was an exciting chance to hear about bunnie's adventures in his own words.
Below I've included the notes I made before recording the podcast, and if you find them helpful they are available for browsing (in Markdown formatting).
# Podcast notes
## Who is bunnie?
- bunnie is a hardware hacker (see book title) and academic
- bunnie has a lot of experience with projects inside and outside academia
-- he's kind of like Henry Jenkins that way
-- major projects include chumby, Novena, and Chibitronics
-- studied at the MIT Media Lab, has taught there too
- runs a "name that 'ware" monthly project on his blog
- a giant nerd (see nerd references throughout)
## What is The Hardware Hacker about?
- bunnie's journey through manufacturing in Shenzhen
- bunnie's thoughts on free culture and the shanzhai/gongkai
- bunnie's thoughts on how to start manufacturing
- ends with his forays into bio sciences and applications of CS tools/principles
### A few notes on the book as an artifact
- published by No Starch Press, known for publishing stuff by hackers
- I'm a little disappointed that Chibitronics didn't make it an electronic cover
-- that gets explained implicitly later in the book. it turns out that's really hard!
- includes an EFF membership ad in the back
## What is the book's purpose?
1. to share bunnie's experiences
2. to demystify Shenzhen and its people
3. to provide practical guidance to people on a similar path
## What's cool about the book?
- moves through four parts:
-- general manufacturing in China (and anywhere)
-- IP in China (authenticity)
-- open hardware through three projects
-- hacker's perspective on bio sciences
- bunnie's sense of wonder and excitement are real and palpable
-- it's inspiring! I ordered a replacement Kindle screen while reading the book because I was so inspired to fix things.
- at this point, he's been doing a decade of manufacturing in Shenzhen. that's a lot of experience!
- the factory workers are really people to bunnie, and he goes out of his way to humanize them
- bunnie has a unique perspective on life. he's really living his principles, and it shows.
- all of his writing surfaces the behind-the-scenes work he and the other people involved in manufacturing put into a product
-- he puts his money where his mouth is by consistently releasing open hardware even when it gets ripped off
## The Hardware Hacker has a global scale
- capitalism, ewaste, and IP have global consequences
- bunnie envisions a better world for all of us
## What is authenticity?
- the somewhat nebulous idea of authenticity plays a major role in the book
- as a producer, bunnie has to be wary of low-quality or substituted parts
- but what is authentic really? many "fakes" were produced on the same equipment by the same people
- regulation of ewaste would help, since it is a major source of low-quality parts
- he induces a certain amount of paranoia because a lot of fakes are only detectable if you have serious experience
## What are the shanzhai and what is gongkai?
- the shanzhai are a tight-knit community looked down on by some
-- if you betray the shanzhai, you aren't welcomed back
- gongkai is actually integrated with manufacturing, since sharing designs is a way to promote your factory
- gongkai is not the same as open source in the US
-- gongkai uses community standards in place of lawyers
-- support (in the sense of a help line) is minimal, but then same for FLOSS
- US/western open source relies on licensing terms
-- incompatible with gongkai in some ways since licensing has strict requirements and legal recourse

For my maker interview, I decided to interview my dad, Mark Hopkins. As someone who taught me and participated in much of my early making, I wanted to learn about his perspective on our family making, as well as to investigate his process as a maker. Now retired, he is working on exciting new projects that put making center stage.
I also want to note I think this interview largely leaves out an important figure in our family making: my mom. Because such an omission isn’t intentional, it’s all the more important to call it out. She taught me baking and early sewing, did the physical and emotional labor of taking me to events, and made art a constant presence in our household. I think an interview with her would be equally interesting and illuminating, and I hope to do one for my own purposes after the semester.
One of my earliest memories is of seeing my dad’s face on a billboard. I believe we were driving to the airport to fly to Spain, where we’d live for the next few months while he worked on setting up a new factory. As we drove up I-95, we saw his face staring down at us. At the airport, we saw him again, staring at us from an ad. Around the same time, a TV crew interviewed him at our house for a PBS special on inventors. To me, my dad has always been a bigshot inventor.
Equally early memories include riding in antique cars with him, shooting model rockets into the sky, and riding our bikes everywhere. Throughout my childhood, my dad helped me with Science Olympiad, where we built bridges and trebuchets, and taught me how to apply science to rocket-building. But his story of making goes farther back.
In the summer of 1963, dad learned to ride a bike. Not far from where my parents live now in Newark, DE, he started by coasting down a hill at the old farm with his cousins and uncle. Despite how fraught with disaster learning to ride a bike usually is, he doesn’t remember falling over (though he admits he may simply have forgotten). Later, in 1970, he was living in Kitchner, Ontario and got his first ride on a ten-speed bike. “I remember the street lights and the wind in my hair,” he says. That ride helped set the course of his life.
My dad doesn’t know much about the maker movement, but it’s still a label he’s comfortable claiming for himself and he’s interested in learning more about the larger movement. “I just started reading Free to Make, and I’ve heard the term, certainly. My initial impression is that it’s about getting people to see themselves as people who can build things...There’s something valuable in building - commercially, or because it’s new, or just to practice something. My mom knitted, and she did it because she liked to. She was a maker.”
My grandparents were major influences in my dad’s childhood making. My grandmother spun yarn, knitted, sewed, and quilted. She was also an avid gardener who would have been fascinated by the possibilities of Arduino soil sensors. My grandfather actually assembled an entire antique car in his basement in Lansing, only to disassemble it, take it outside, and re-build it when the weather turned fair.
My grandfather often took my dad and uncle to model rocketry meets. My dad initially started building kits, but quickly got into competitions in which he had to design and build the rocket himself from scratch. The competitions would often have very specific competitions, such as carrying a payload, so the rockets would need to be purpose-built.
The rocketry meets were ideal for a child raised in the burgeoning space age. Many of the participants worked for NASA, and the meets were often held at NASA or military sites. My dad would never miss an actual NASA launch, either. He watched on TV or listened on the radio whenever possible.
Rocketry meets were major undertakings, but they were organized before the Internet (though some participants were likely using ARPANET, given the heavy NASA and military presence). Enthusiasts read rocketry magazines and joined local clubs, much like the science clubs of Onion’s Innocent Experiments, through which they were connected to the larger rocketry community.
Shortly after he learned to ride a bike, my dad started making his own bike wheels. With the benefit of Richard’s Bicycle Book and a class at a conference in Carlisle, PA, he began making and replacing his own spokes and rims as necessary. While studying engineering at the University of Delaware, he and a group of fellow cyclists decided to make a human powered vehicle to enter a land speed competition.
The team was sponsored by Campangolo, still a major bicycle parts manufacturer, and they learned the technical skills they needed from a local bicycle store called Two Wheeled Cycle. The vehicle reached 52 mph with three riders powering it. They competed against companies like General Dynamics, which actually hired professional riders to power the vehicle.
Later, as a young engineer in DuPont’s field program, he joined the composites business. DuPont had bought Exxon’s satellite parts division, and wanted to start making their own parts. After visiting a bicycling trade show in 1987, my dad convinced his manager that the bike industry was ripe for a new parts manufacturer. Specifically, he decided to try making a new bicycle wheel. He and his collaborators had some ideas for a more aerodynamic design that used three spokes and looked like an airplane propeller.
Initially, no one could understand how the wheel was supposed to work. They couldn’t visualize how it would work, or how the force would be distributed. So one night, my dad and his collaborators sketched a design on his plywood workbench and cut it into what would become their prototype (he still has it). When I asked him how long it would have taken to produce a more traditional prototype, he reminded me that they didn’t have the institutional support at that point to actually produce a prototype. They were able to fabricate one out of wood, when a full prototype would have taken weeks once it was approved.
The wooden prototype was key to the project’s success. With the prototype, made by hand out of a table, my dad and his team could excite their managers about the project and bring it to fruition. The wheel is still in use today in time trials in the Tour de France and other major races.
My dad described the wheel’s manufacturing process to me, and one thing in particular reminded me of bunnie Huang’s experiences in Shenzhen. When the wheel business was sold to a company in Spain, my dad was responsible for configuring their plant and getting it into production. The Spanish plant had a newer, better process than what had been available in Delaware, but it meant that he had to do a significant amount of debugging as they translated the process (linguistically and logistically). He had to learn from the plant workers as much as he was teaching them. It reminded me of how bunnie needed to learn from the factory workers how they assembled components so that he could design the process to work for them.
Now, almost thirty years later, my dad is returning to making bicycles. He started working for a company called 3T about 18 months ago, and about 15 months ago started laying out a new plant for them to begin making bicycle frames and parts. In the intervening years, he’s learned new skills, like supply chain optimization, and he’s hoping to achieve something called slow manufacturing with this new plant. It reduces waste, has a smooth single-directional flow, and raw materials go in one end with finished parts coming out the other.
Beyond bikes, my dad also makes household items that he needs, like re-covering kitchen chairs, and parts for antique cars. The cars, originally built in 1914 by the Overland company, don’t have parts you can pick up at a dealership. The wheels are wooden and the driver’s seat cushion has to be lifted up to fill the gas tank beneath it. Actually driving the vehicles requires brute physical strength due to the lack of power brakes or steering. If something breaks, as often happens, it has to be repaired or fabricated with what’s on hand.
I asked my dad specifically about the making that he taught me as a child. He said he never really thought of it that way. He was just playing with me, teaching me some of the things that he learned and enjoyed during his own childhood. My LEGO sets might be a little different (I still build Star Wars LEGO today) but at their core they are still the same imaginative construction sets my dad built with.
My dad has always been the quintessential maker, to me. I feel fortunate I’m able to interview him and interrogate our shared history of making.
