Friday Hack Chat: Making In Shenzhen

August 30, 2017 by Brian Benchoff 7 Comments

China is an amazing land of opportunity, and if you want to build anything, you can build it in Shenzhen. This city that was just a small fishing village a few decades ago has grown into a cyberpunk metropolis of eleven million and has become the manufacturing capital of the world. You’re probably reading this on a device made somewhere around Shenzhen.

For this week’s Hack Chat, we’re going to be talking about manufacturing in Shenzhen. We’re bringing in a very special guest for this one: [Naomi Wu] is a Cantonese DIY maker, professional web dev, transhumanist, electronics reviewer, occasional Hackaday contributor, vlogger, 3D printerer, advocate of women in STEM, SexyCyborg, and a riot on Twitter. [Naomi] also lives and works in Shenzhen, and is tapped into the DIY and maker culture there. She’s created 3D printed pen testing shoes, a Raspberry Pi cosmetics case, and infinity skirts.

This Friday (or Saturday, depending on which side of the date line you’re on), [Naomi] is going to be talking about manufacturing, making, DIY, and Shenzhen culture. Of particular interest will be electronics purchasing and manufacturing in Shenzhen, designing wearable projects with an emphasis on power and thermal design, documenting projects, and Shenzhen culture. This is basically an AMA, so if you have any questions you’d like to ask, throw them up in this spreadsheet.

Here’s How To Take Part:

Our Hack Chats are live community events on the Hackaday.io Hack Chat group messaging. Hack Chats are usually at noon, Pacific time on Friday. This week we’re doing the Hack Chat a little later, because timezones. This week’s Hack Chat will be at 6 pm PDT Friday / 9 am CST Saturday. Confused? Here’s a time and date converter!

Click that speech bubble to the right, and you’ll be taken directly to the Hack Chat group on Hackaday.io

You don’t have to wait until Friday; join whenever you want and you can see what the community is talking about.

Q Has Nothing On Naomi Wu

We’re not so much fans of James Bond as we are of Q, the hacker who supplies him with such wonderful things. There is a challenger to Q’s crown, [Naomi Wu] — code name [SexyCyborg] — built an epic gadget called the Pi Palette which hides a Linux laptop inside of a cosmetics case.

You can see the covert mode of the Pi Palette below. It resembles a clamshell cosmetics case with the makeup and applicator in the base and a mirror on the underside of the flip-up lid. The mirror hides an LCD screen in the portrait orientation, as well as a Raspberry Pi 3 running Kali Linux.

The base of the case includes a portable battery beneath the wireless keyboard/touchpad — both of which are revealed when the cosmetics tray is removed. An inductive charger is connected to the battery and [Naomi] built a base station which the Pi Palette sits in for wireless charging.

She envisions this as a covert penetration testing. For that, the Pi Palette needs the ability to put the WiFi dongle into promiscuous mode. She wired in a dual dip-switch package and really went the extra mile to design it into the case. The fit and finish of that switch is just one tiny detail the illustrates the care taken with the entire project. With such a beautiful final project it’s no wonder she took to the streets to show it off. Check that out, as well as the build process, in the video after the break.

Hackaday Links: December 18, 2016

You can fly a brick if it has offset mass and you can fly a microwave because it breaks the law of the conservation of momentum. A paper on the EM Drive was recently published by the Eagleworks team, and the results basically say, ‘if this works, it’s a terrible thruster that shouldn’t work’. Experts have weighed in, but now we might not have to wait for another test in the Eagleworks lab: China will fly an EM Drive on their space station. Will it work? Who knows.

The ESP32 is just now landing on workbenches around the globe, and already a few people are diving into promiscuous mode and WiFi packet injection.

The Large Hadron Collider is the most advanced piece of scientific apparatus ever built. It produces tons of data, and classifying this data is a challenge. The best pattern recognition unit is between your ears, so CERN is crowdsourcing the categorization of LHC data.

Holy crap this is cyberpunk. [SexyCyborg] created a makeup palette pen testing device thing out of a Rasberry Pi and a few bits and bobs sitting around in a parts drawer. The project is cool, but the photolog of the finished project is awesome. It’s exactly what you would use to break into the Weyland-Yutani database while evading government operatives on the rooftops of Kowloon Walled City before escaping via grappling hook shot into the belly of a spaceplane taking off.

The Mini NES is Nintendo’s most successful hardware offering since the N64. This tiny device, importantly packaged in a minified retro NES enclosure, is out of stock everywhere. That doesn’t matter because now there’s a mini Genesis. The cool kids had a Genesis. You want to be a cool kid, right? Mortal Kombat was better on the Genesis.

The Arduino (what once was two is again one) launched a new vowel-hating model: MKRZero. The narrow board is powered by USB or LiPo, centers around an Atmel SAMD21 Cortex-M0+ chip, and sports both an I2C breakout header and a microSD card slot. Just watch those levels as these pins are not 5v tolerant.

The American Association for the Advancement of Science is holding a Scientific Maker Exhibit during its annual meeting. This type of exhibit isn’t a poster or presentation — it’s just some table space and a chance to show off a 3D printed apparatus, a new type of sensor, equipment, or some other physical thing. Details in this PDF. This is actually cooler than it sounds, and a significant departure from the traditional poster or presentation found at every other scientific conference.

Did you know Hackaday has a retro edition made specifically for old computers connected to the Internet? That’s my baby, and it’s time for a refresh. If you have any feature requests you’d like to see, leave a note in the comments.
