Review: The New Essential Guide To Electronics In Shenzhen

The city of Shenzhen in China holds a special fascination for the electronic hardware community, as the city and special economic zone established by the Chinese government at the start of the 1980s it has become probably one of the most important in the world for electronic manufacturing. If you’re in the business of producing electronic hardware you probably want to do that business there, and if you aren’t, you will certainly own things whose parts were made there. From the lowly hobbyist who buys a kit of parts on AliExpress through the project featured on Hackaday with a Shenzhen-made PCB, to the engineer bringing an electronic product to market, it’s a place which has whether we know it or not become part of our lives.

First, A Bit Of History

At a superficial level it’s very easy to do business there, as a quick trawl through our favourite Chinese online retailers will show. But when you’ve graduated from buying stuff online and need to get down to the brass tacks of sourcing parts and arranging manufacture, it becomes impossible to do so without  being on the ground. At which point for an American or European without a word of Chinese even sourcing a resistor becomes an impossibly daunting task. To tackle this, back in 2016 the Chinese-American hardware hacker and author Andrew ‘bunnie’ Huang produced a slim wire-bound volume, The Essential Guide to Electronics in Shenzhen. This book contained both a guide to the city’s legendary Huaquanbei electronics marts and a large section of point-to-translate guides for parts, values, and all the other Chinese phrases which a non-Chinese-speaker might need to get their work done in the city. It quickly became an essential tool for sourcing in Shenzhen, and more than one reader no doubt has a well-thumbed copy on their shelves.

There are places in the world where time appears to move very slowly, but this Chinese city is not one of them. A book on Shenzhen written in 2016 is now significantly out of date, and to keep pace with its parts that have since chanced beyond recognition, an update has become necessary. In this endeavour the mantle has passed to the hardware hacker and Shenzhen native Naomi Wu, someone with many years experience in introducing the people, culture, and industries of her city to the world. Her updated volume, The New Essential Guide to Electronics in Shenzhen has been the subject of a recent crowdfunding effort, and I was lucky enough to snag one. It’s a smart hardcover spiral-bound book with a red and gold cover, and it’s time to open it up and take a look. Continue reading “Review: The New Essential Guide To Electronics In Shenzhen”

It’s hard to believe it, but the Raspberry Pi has been on the market for only seven years now. The single-board computer has become so entrenched in the hobby electronics scene that it’s hard to imagine life without it, or what we did before it came along. And with the recent announcement that the 30 millionth Raspberry Pi was recently manufactured, now we have some clarity on the scale of its success. Just roll that number around in your head for a bit – that’s one Pi for every nine or so people in the USA. Some of the other facts and figures in the linked article boggle the mind too, like Eben Upton figured they’d only ever sell about 10,000 units, or that the factory in Wales where most Pis are made can assemble 15,000 units a day.

Speaking of manufacturing, have you ever considered what goes into getting a small-scale manufactured product ready for shipping? The good folks over at Gigatron know all about the joys of kitting, and have put together an interesting un-unboxing video for their flagship TTL-only retro computer. It’s a nice riff on the unboxing videos that are somehow popular on YouTube these days, and shows just how much effort they put into getting a Gigatron out the door. All told, it takes about an hour to ship each unit, and the care put into the process is evident. We especially like the part where all the chips are placed into antistatic foam in the same orientation they’ll be on the completed board. Nice touch.

Last time we checked in on the Lulzbot saga, the open source 3D printer manufacturer had been saved from complete liquidation by a company named FAME 3D. Now we’re getting the first solid details about where things go from here. Not only will thirteen of the remaining Lulzbot employees be staying on, but FAME 3D plans to hire 50 new employees to get operations back up as quickly as possible. The catch? The “F” in FAME 3D stands for Fargo, North Dakota, where Fargo Additive Manufacturing Equipment 3D is based. So Lulzbot will be moving north from Loveland, Colorado in the coming months.

For the last few years, adventure travelers making the pilgrimage to Shenzhen to scour the electronics markets have stuffed a copy of Andrew “Bunnie” Huang’s The Essential Guide to Electronics in Shenzhen into their soon-to-be-overflowing backpacks. The book is a goldmine of insider information, stuffed with maps and translation tables critical for navigating a different culture with no local language skills. Bunnie’s book has only been available in dead-tree format and now that all but the last few copies have been sold, he decided to make a web version available for free. We’d have to think a tablet or phone would be a bit harder to use in the heat of negotiation than the nice spiral-bound design of the print copy, but the fact that the insider information will now be widely available probably makes this a net positive.

And finally, if you’ve ever nearly been run over by an EV or hybrid silently backing out of a parking space, you’ll no doubt appreciate attempts to legislate some sort of audible presence to these vehicles. But what exactly should an electric vehicle be made to sound like? Volkswagen has begun to address that question, and while you can certainly read through the fluff in their press release, all you really need to do is listen to the sample. We’ve got to say that they pretty much nailed what a car of the future should sound like. Although they might have missed a real opportunity here.

Bunnie’s Guide To Shenzhen Electronics

[Bunnie Huang] is now officially the person who wrote the book on electronics manufacturing in Shenzhen, China. His Crowd Supply campaign for The Essential Guide to Electronics in Shenzhen has blown way past the initial goal. [Bunnie] is the first person who comes to mind for anyone needing help getting their electronics built in the region.

The books is meant as a travel companion. Hackaday was in China last June and toured the markets of Hua Qiang Bei. They are incredibly overwhelming, but people are very nice, willing to help, and none of them speak English. [Bunnie’s] approach is pages with squares you can point to in order to express your meaning. Standing at the capacitor stall? There’s a page for that. Gawking at a booth packed full of LEDs and need them in reels instead of tape? That’s in the book too. Even better, this isn’t a one-way thing. You should be able to understand well enough what they vendor is trying to convey as they point at the pages to answer your questions. This is certainly better than our method of trying to find pictures of addresses and Chinese characters on our phones. Everything is at the ready.

It doesn’t end there. The images of the book’s table of contents shows that you’ll get help with getting into the country, getting around once you’re there, and making the deal when you do find what you need. If you’re ever going to make the trip to Shenzhen, this is the first thing you should put in your backpack.

Since you’re already in the mood to purchase something made of paper, we think you’ll be interested you in this gorgeous Hackaday Omnibus Vol 02. It’s 128 pages of the best original content published on Hackaday over the past year, including the stunning artwork of Joe Kim.
