Hackaday’s Guide to Shanghai

We happened to be in Shanghai for Electronica trade fair this year and had a great time exploring heavy industrial gear and fantasizing about all the things we could do with it. However, we simply couldn’t ignore the fact that there was a whole city out there that we’re completely missing out on. So after less than a day of being surrounded by businesspeople and Miss Universe-dressed promoters, we decided to pack our bags and hit the streets.

The question was, where should we go? Finding interesting things in a city that keeps shapeshifting (the whole Shanghai skyline did not exist 20 years ago) can be a challenge. Fortunately, our friend [David Li] gave us a list:

  1. Xin Che Jian
  2. Jiu Xing market
  3. Beijing Lu electronic market
  4. Qiujiang Lu CNC/lasercut market
  5. DFRobot.com

…and off we were.

The Future Doesn’t Need Another Internet-Connected Teddybear – Hackaday at SXSW Create

Hackaday happened to be at South by Southwest this year and visited SXSW Create – part of the festival dedicated to hackers, makers and DIY scene. While modest in size, this event serves as a great contrast to the internet-hype machine omnipresent everywhere else in the city during this time. So we thought we should drop by and show them some love.

sxsw-launchpad-croppedTrey German showed us a couple of great real-time power control demos using his C2000 Launch Pad as well as his Bluetooth Cooler which, for whatever reason, decided to fail on him just in time for the big show. The demo we have been looking forward to the most was a thermocouple-controlled barbecue using Energia framework but were disappointed to learn that The Man has banned grilling hotdogs in the tent. The universe was telling us we’re not here to party.

atx_hackerspace_TARDISATX Hackerspace had a large booth featuring the full-size replica of Doctor Who’s TARDIS (who wouldn’t like to have a picture taken in one ?) and a fully-functional 1930-es vacuum tube radio with a mandatory iPad dock. We have also learned that a massive collection of working vintage vacuum tubes has been donated to the hackerspace, so if you’re in need you know who to call.

The event has also featured a long list of industry participants. The product launch we were most impressed with was Easel by Inventables, an in-browser app that enables easy control of their Shapeoko CNC milling machine and definitely has the potential of bringing the joys of design and fabrication to much larger masses.

e_coli_ut_austin_experiment1However, the most interesting things we saw were the ones a bit outside of the current tech mainstream. [Dennis] from UT Austin iGEM team showed some of the crazy work the synthetic biologists are doing out there. They have engineered Escherichia coli so that it is addicted to caffeine, used cell growth as a measure of caffeine content in particular drinks, and used that to rank local Austin coffee shops! We have also talked with several guys working on automated gardens and soil sensors who were educating attendees about the huge potential that increased environmental data aggregation can have on the ways we grow food.

To quote the Growerbot guys : “We definitely have enough Internet-connected teddy bears. We need more Internet-connected tomato plants”.

Stick with us after the jump to see a gallery with all our adventures at 2014 SXSW.

Shenzhen Tour and UnHuman Soldering Classes with DP

dp-hacker-camp

If you’re free the first week of April and don’t mind sitting on a plane for a looooong time you should check out the Hacker Camp that Dangerous Prototypes is planning. We’re sure you remember [Ian Lesnet] who is a Hackaday Alum, creator of the Bus Pirate, and geeky world traveler. Now’s your chance to try out what to him is a way of life.

The event is April 3-5 in Shenzhen, China. Although marketed as a “Hacker Camp”, to us it sounds more like training for those interested in running hardware companies that use the Shenzhen manufacturing district as the anchor of their supply chain. Part of the prep-work for the trip includes submitting board files which will be fabbed and ready for you on the first day. [Ian] and his crew will be your guides for the culture of the area; complete with meals and bar time. But there are also soldering workshops as part of the package. Don’t pooh-pooh the idea. This is unhuman soldering… BGA and QFN soldering instruction from the people who repair cellphones and other microelectronics.

This [Rick Steves] style adventure is the first that we remember hearing about that targets the open hardware community. But we must admit, it sounds like a lot more fun than a European river cruise!

Touring Component Markets in Shenzhen

touring-component-markets-in-shenzhen

[Al] recently returned from a trip to China. While there he toured some of the component markets in Shenzhen, the electronics assembly epicenter of the world. While he doesn’t focus too closely on what is actually being sold there, we found his description of the markets themselves and other notable attractions around the area quite interesting.

Shenzhen is different from some of the other component wonderlands we’ve heard about ([Ian Lesnet's] tour of Akihabara in Japan comes to mind). First of all it may be a bit more difficult to get there. US Citizens need a Visa to enter China, and must fly to Hong Kong and take a ferry to the mainland. [Al] reports that the traffic is horrendous and rush-hour can turn a ten mile ride that usually takes ninety minutes into a three hour tour… a three hour tour!

The side affect of the market being out of the way is that the prices aren’t as inflated as they may be in more geek-tourist-friendly locations. That being said it also sounds like the vendors are interested in selling you a few thousand units rather than a single component. Follow the link at the top for the market tour, a stop at Seeed Studios (who will apparently sell you a map of the best markets to visit), and the rest of the attractions that [Al] encountered.

Hand placing flash die to make USB drives

SONY DSC

It’s a stretch to call this one a hack, but USB thumb drives are around us constantly and we always assumed that the boards inside were machine populated (like with a pick and place machine). [Bunnie] tells us otherwise. He recently had the chance to tour a factory where USB flash drives are made.

The image above shows a worker populating a set of boards with the flash memory dies. The waffle-grid to the right holds the dies. Each is a tiny glint of a component. The worker is not in a clean room, and is using a bamboo tool to pick up the pieces. [Bunnie] explains that he’s seen the tools before but doesn’t fully comprehend how they work. He figures that the hand-cut manipulator has just the right amount of grab to pick up the die, but will also release it when it touches down on the dot of glue applied to the landing zone on the board.

If you’re into this sort of thing you should check out the PCB factory tour we saw a couple of years back. The article link is dead but the embedded tour video still works.

Hackerspace intro: HeatSync Labs

heat-sync-labs

[Todd Harrison] wrote in not with a project but with a video tour of his local hackerspace: HeatSync Labs in Mesa, Arizona. He took a camera along with him over the weekend to record what you can expect when visiting the space. You’ll find the tour embedded after the break.

It starts off with something we love to see. The space is being used for a talk and it looks to be quite well attended. The building is one unit in a string of storefronts and this provides a big open space as soon as you walk in the door. Just past this gathering area there are a few rows of electronics work benches which include hardware like bench supplies and scopes, as well as soldering and rework areas. In the back corner they’ve got a great big laser cutter and [Todd] spends some time with one of the members looking through all the fun stuff they’ve made with it. The back room keeps the messy projects like wood working, machine tools, and welding separate from the rest.

The place is remarkably clean and we’ll organized. Make sure you stop by and check it out for yourself if you’re in the area.

This is the second time we’ve seen HeatSync Labs. The first tour was hosted by our own [Caleb Kraft]

Hackerspace Tour: Kwartzlab

Located in Kitchener, Ontario, Kwartzlab is a 3000 square foot hackerspace. In 2009, the group was founded and set up their space in a former box factory. We dropped by the space on one of their Tuesday Open Nights to take a tour. Join us after the break for a quick walk through of Kwartzlab.
