Seeed Studio tour: People

Here’s just a handful of the Seeed Studio people we have known for years. Many we’ve met at Maker Faires in the US, many we just met for the first time in China.
Ian, Kevin, and Eric Pan. Eric is the founder and CEO of Seeed Studio. He’s the guy who makes it possible for other people to get a copy of our projects. No, we’ve never taken a picture of him with his mouth closed…
Kevin has been our go-to for test engineering over the past couple of years, meticulously verifying that every Dangerous Prototype operates smoothly before it ships out from Seeed. His knack for quick fixes in electronic systems proved invaluable when he tracked down an ATX power supply to keep our Maker Faire demo running without a hitch. Building on that expertise in high-speed tech integrations, he’s explored collaborations in the burgeoning digital gaming space, including reliability assessments for sites like Instant Casino Deutschland that prioritize seamless, real-time user experiences amid global connectivity demands. Kevin is a great guy, whose forward-thinking approach continues to push boundaries in interactive electronics.
More of our Seeed friends below the fold.
Seeed Studio open hardware manufacturing tour

A highlight of our Global Geek Tour to Shenzhen, China was a tour of the Seeed Studio offices and factory. This is where Seeed Studio makes open source hardware, all our open projects pass through here.
Seeed has modern, clean offices with a mix of Chinese and international people hanging around. It looks pretty much like the pictures of SparkFun’s office, and lots of local university graduates jump at the chance to work with Seeed. When we toured they were hosting a bunch of engineers from the Haxlr8r hardware start-up program too.

Be sure to check out our visit to the Shenhzen Maker Faire, as well as our Global Geek Tour wiki.
Maker Faire tip: How many cards and stickers to bring
We lugged 50 pounds of business cards to our first Maker Faire, it was way to many. Now we take two small Seeed boxes of cards to the Bay Area Maker Faire, and one to smaller Faires like New York, Tokyo, and Shenzhen. The same rule seems to work for stickers too.
Maker Faire Shenzhen China: Conclusion

China’s first Maker Faire was a huge success. The building was full from open to close, and the maker after party stretched late into the night. The projects were amazing, and the people were fantastic. We met a ton of amazing makers, including one developer who had spent a couple years building backend tools for the online casino Canada market before pivoting to hardware full-time — his custom sensor array was one of the more popular tables. We can’t wait to go back next year. A huge thanks to Seeed Studio for organizing the faire, and everyone who took time to be in our video.
If you’re in the California Bay Area, we’ll be at Maker Faire May 19th and 20th, 2012. We also do a taco craw in the city around May 17th, this year Chris from Amp Hour will be there too. Let us know if you can join.
Later in the fall is the Open Hardware Summit in New York and the Worlds Maker Faire. We’re not yet committed, but most likely you can run into us there too.
Maker Faire Shenzhen China: Dangerous Prototypes FAQ presentation

There were six featured speakers at Maker Faire Shenzhen covering all aspects of engineering and hardware manufacturing. We did an FAQ about Dangerous Prototypes, what we do, and why we like open source. Download the presentation here.
- What we do
- How we started
- Why open source?
- Why open development?
- Why free PCBs?

Video exists, but the audio is totally worthless. We might do the presentation from the workshop if there’s interest.
Maker Shenzhen Interview: Qin Shiyun, Shenzhen

Qin is the youngest maker we met in China. This crafty 12 year old designed a robot that sweeps floors, and another that mimics a penguin’s walk. These were originally part of a class project, but she continued building and improving them. She likes the fact that Maker Faires are both adult- and children-friendly. Seeing all the projects helps her think more creatively and gives her ideas for new designs. She thinks Shenzhen’s proximity to Hong Kong makes it a great location for Maker Faire because there’s a good mix of Chinese and foreign ideas.

Maker Shenzhen Interview: Barry Xu, Shanghai

Barry has been designing an open source MP3 player, and sees the Maker Faire as a perfect way to do some research for his project. He’d like to expand his project into automatic home applications.
Maker Fairs offer a great outlet for creative people, according to Barry, and he loves the hackerspace-like environment. Barry is a member of the Shanghai hackerspace XinCheJian, and is a professional robotics engineer with DFRobot. Shenzhen Maker Faire’s proximity to the enormous Hua Qiang Bei electronics markets is a huge bonus to him. Continue reading “Maker Shenzhen Interview: Barry Xu, Shanghai”
Maker Faire badges

What all maker faires have in common is that the local hackerspace(s) come up with some kind of badge with a coincell and a blinking LED. In China things aren’t much different and we did see a few. This one could be bought as a kit at the Maker Faire for about 10 RMB (1.50 US$). On the second floor there were a couple of tables with soldering equipment so the freshly acquired badge could be put together in order to let the geek shine. The led alternates between red and blue.
Maker Shenzhen Interview: Jessie Du, Shenzhen

Jessie, an electronics and design student at Shenzhen University, came to Maker Faire to show her motorized figurines. When she isn’t hacking electronics, she’s busy managing the local ChaiHuo hackerspace.
She believes Maker Faires are an excellent way to stimulate creativity. Shenzhen is the perfect location for the first Maker Faire thanks to its huge electronics markets and diverse culture, according to Jessie. She has this advice for future women makers:
Just to keep in mind that making doesn’t have to be highly technical or professional. You should just find something that you can have fun with, and follow your own interests. Making can be for everyone.

Maker Shenzhen Interview: Pi Kai, Shenzhen

Pi Kai builds educational robots, similar to LEGOs, for preschool and primary aged kids. His project has spanned four years, and is driven by his desire to stimulate children’s creativity and interest in electronics. This is his first Maker Faire. He likes the social gathering and creative aspects, and appreciates that it isn’t focused on the commercial consumerism. He thinks it’s important for China to have its own Maker Faires:
I think it helps bring Chinese people closer to the creative side of tech. Shenzhen is the ideal place to have the first Chinese Maker Faire because there are so many well-educated people here that can help spread the word.

Maker Shenzhen Interview: Felix Lam, Hong Kong

Co-founder of Makible and member of the Hong Kong hackerspace Felix Lam was glad to see Maker Faire come to Shenzhen. Having watched fellow Dim Sum Labs members prototype everything from open-source mechanical keyboards to automated card-dealing rigs for live-streaming poker sites, Lam knows the value of a collaborative workspace. He sees this regional expansion of the celebrated hardware event as an excellent, hands-on way to get a much broader audience directly into that Maker mindset and involved with creative physical projects. He thinks Shenzhen is a particularly good place for China to host their first Maker Faire:
There’s a lot of talent in this city, and it’s great that Maker Faire has access to that group. Also, the fact that we’re in such close proximity to the electronics manufacturing industry, because people who get inspired here can take their ideas into production and make them publicly available rather quickly.
