YN460 is a nice Chinese made flash for photography. The first hack is to enable controlling the power and flash trigger with Arduino. In the following video, the Arduino runs a 3 second step that trigger at its 7 power level.
Next step, adding network capacity to the flash and control it from iPhone!

A few days ago Michael sent out this update about the 3D Printer:
Sorry for the lack of updates on the 3D printer. The white ABS [Acrylonitrile Butadiene Styrene; a thermoplastic] is horrible. Use the grey PLA [polylactide; thermoplastic aliphatic polyester] from now on. I reinstalled the old nozzle (made a new one and promptly burned it out the same day) and was able to print without making any changes. It actually sticks to the platform and to each other. Was able to get 1/3 of the 2cm box before it sheared off. Still have problems with flow control, but happy that it works better. The toothed gear may be too sharp, since it jams up with plastic after a while. Need to clean it out every so often, but it still pulls filament even when jammed. Also started to wrap up the wiring.
I’m going to be out of town for a while, so who ever wants to take over and get it flowing better, be my guest.
We (Ricky Ng-Adam and Min Lin Hsieh) were invited by Professor Benjamin Koo from Tsinghua university to make a trip to Ningbo last Thursday to visit one of the university that Professor Koo is helping. The Ningbo Polytechnic is located in the Beilun development zone. It’s a 3.5 hours drive away from Shanghai. Ningbo Polytechnic is at the top of the list of vocational schools in China, working hard to become an alternative to more well known brands in China with a focus on practical skills.
All universities in China have their own hotels, travel agencies, on-site restaurants with copious amount of food (always too much)… Impressive for foreigners that are not used to this level of luxury on campus! We visited the rest of the campus where they host many exchange students from Africa and elsewhere. We also saw a wonderful violin making studio (they have a store with price tags next door) and an absolutely HUGE CNC (computer numerical control) room that is used to produce mechanical parts of all size and shapes.
The main objective of our visit was to check out Toyhouse, a Hackerspace-type space located on the university campus and created by Professor Koo. As their name implies, as a whole bunch of toys (lots of RC copters). They were also recently the host of a quadcopter workshop. Afterwards, we visited a film studio fully equipped to produce entire movies literally across the street from the university in a large technology park.
During our visit, we and Professor Koo had a discussion about creating a new university program to make it possible for students to find their passion and be as desirable candidates as possible to employers and investors when they come out of the program. Our suggestion is to build a project-centric program with guests hackers from around the world.
Techyizu and Xinchejian are proud to issue a challenge of supreme nerdiness: Who among you can build the mightiest bridge? Who has the superior spaghetti engineering skills?
For those of you brave enough, register to join the fun THIS SUNDAY!
DATE: Sunday January 15 @ 1:00 PM – 5:00 PM
LOCATION: Xinchejian Hackerspace
Anhua Road No.76 suite 301, near Jiangsu Road (http://xinchejian.com/contact-us/)
Form your own team or join one, and get ready to architect and construct a bridge made out of spaghetti. Bridges have to be able to cross a 50 cm distance, and hold as much weight as possible. Techyizu and Xinchejian will provide you one box of spaghetti, glue guns, and glue. You provide the nerdpower.
See the full list of rules (http://xinchejian.com/event/?ee=91) on the Xinchejian website.
PRIZES: ARDUINO sets will be given to the teams with the bridges that can support the most weight.
Calling all techies, entrepreneurs, and innovators — get ready for Techyizu’s BARCAMP on March 3.
BarCamp is a fun, user-generated “un-conference” that started in Silicon Valley as a response to formal, exclusive, and boring tech conferences. If you are interested in technology, startups, design, or social innovation, you can’t miss this event!
BarCamp consists of passionate 15-minute presentations on any topic. Anyone (yes, anyone!) can sign up to present on anything (but please, no advertisements for your company). Just let your own energy and nerdiness shine through. All presentations are followed by time for discussion. You can expect to have amazing discussions on cutting edge technology and trends.
The event is free and open to everyone! Go to the techyizu.org website for more event details.
Shanghai BarCamp is being presented to you by TechYizu, an organization that aims to organize Shanghai’s lively startup and tech community.
1. Each group is to build a bridge made from spaghetti and hot glue. The object is to construct a bridge that will carry the heaviest load while still meeting specifications. Bridges will be loaded until they fail.
2. The bridge is to be built from and only from the given materials:
* 1 bag of spaghetti (500g)
* 5 hot glue sticks
* 1 metal hook for weight attachment
* 2 hot glue guns that cannot be used in the bridge structure
3. The bridge shall be free-standing and must span two level surfaces which are 50 centimetres apart.
4. The edges of the level surfaces cannot be used in any way for support.
5. The bridge must incorporate the given metal hook as part of the structure. The testing weight would be attached to the hook. Any structure that forbids attachment of the testing weight would disqualify the bridge.
6. The maximum vertical depth of the bridge, from the highest point in its structure to the lowest cannot exceed 50 cm.
7. The highest point of the bridge cannot be higher than 40cm above the two level surfaces, the lowest point of the bridge cannot be lower than 20 cm below the two level surfaces.
8. Only the first 12 registered teams would be eligible to enter the competition, each team is allowed up to 4 participants.
A. Any bridge that fails to stand on its own and span the two level surface would be disqualified.
B. A spring weighting scale would be attached to the hook, and a empty bucket would be attached below the weighting scale. Any bridge that failed to support the weighting scale and bucket would be disqualified.
C. Participants will be adding weight to the bridges themselves, judges would make recordings of the weight loaded.
D. The last recorded weight from the spring weighting scale before the bridge structure fails would be counted as the result (total loaded weight) of that particular bridge.
E. A bridge structure would be considered failed if:
* Bridge fails to stay free standing between the two level surfaces
* 50% of the bridge structure falls off from the main structure to the ground
* The lowest point of the bridge is more than 10cm below its lowest point in free standing position
F. Teams will be ranked on their result, the total loaded weight measured, bridge supports the most weight wins.
G. The judge have the last undisputed say on the out come of the competition. Judge has the right to disqualify any team at any given time without any reason.

We’ve had the pleasure of welcoming four students from MIT last Saturday. You can check out the blogs of two of them: Nancy Ouyang, Cathy Wu. These students were on a self-funded, personal visit to China where they visited a number of factories and Chinese makerspaces/hackerspaces. They are members of MITERS, a 30 years old student club at MIT.
Originally founded as a club to give MIT students free and open access to computers, MITERS now features a mill, lathe, band saws, welders, and other hands-on tools, in addition to a host of oscilliscopes, high-end soldering irons, and other EE prototyping tools. It’s a member-run creative haven and build-anything-you-want, if-you-break-it,-fix-it space.
The event was very popular and we had a full house. The large audience included MIT alumni Benjamin Koo (and his assistant Jeadon Chen) in addition to a few students interested in opening hackerspaces-type organizations inside their own universities. Throughout their presentation they shared with us how they ran their space and what type of projects they did in addition to their impressions of China.
Happy New Year – Welcome to 2012, this is the first update of the year.
