A Tech Entrepreneur's Guide To Visiting Shenzhen
Freetronics is Australia's answer to a lot of electronic tinkerers' needs, selling items like Arduino compatible boards, cables, and specialized tools. Founder Jonathan Oxer is a (serious) electronics hobbyist himself; he talked with Slashdot last year about making ArduSats, which were then launched to the International Space Station. Now, Oxer has written an excellent guide for hobbyists who might get the chance to travel to Shenzhen, where so many of the world's electronic bits and bobs are made. As travel writing goes, it's fascinating for the sheer novelty of the place. If you actually have the chance to go, some of the advice here might save you money and time. For those of you who have been to Shenzhen, what else should visitors know?
Beware of Gutter Oil. http://www.youtube.com/watch?v... Only take red or blue (electric) taxis. The guys at Shenzhen Bay who want your business will charge 2-5x the regulated rate.
If you are a casual technogeek, save yourself about $4000 and just go on AliExpress and buy whatever knicknacks you are interested in straight from Shenzhen. What, did you think they haven't figured out ecommerce? If you do have the chance to visit (i.e. for work), or are really after niche goods/services (in particular, to start your own import business) then certainly its a great place to go. But if you are just looking to get out of the US, don't go to Shenzhen just to browse around Huaqiangbei. There are plenty of other, far far more exhilarating/enlightening/relaxing places to visit in the world.
