Bunnie Huang Talks Manufacturing And Component Choices During Hackaday Prize Mentoring Session

Andrew “Bunnie” Huang’s mentor session for the Hackaday Prize shows off the kind of experience and knowledge hard to come by unless you have been through the hardware development gauntlet countless times. These master-classes match up experts in product development with Prize entrants working to turn their projects into products. We’ve been recording them so that all may benefit from the advice and guidance shared in each session.

Bunnie is someone who is already familiar to most Hackaday readers. His notoriety in our community began nearly two decades ago with his work reverse engineering the original Microsoft X-box, and he quickly went on to design (and hack) the Chumby Internet appliance, he created the Novena open-source laptop, and through his writing and teaching, he provides insight into sourcing electronic manufacture in Shenzhen. He’s the mentor you want to have in your corner for a Hackaday Prize entry, and that’s just what a lucky group had in the video we’ve placed below the break.

While this session with Bunnie is in the bag it’s worth reminding you all that we are still running mentor sessions for Hackaday Prize entrants, so sign up your entry for a chance to get some great feedback about your project.

The first team to meet with Bunnie are FunKey, whose keychain Nintendo-like handheld gaming platform was inspired by a Sprite_tm project featuring a converted novelty toy. The FunKey team have produced a really well-thought-out design that is ready to be a product, but like so many of us who have reached that point they face the impossible hurdle of turning it into a product. Their session focuses on advice for finding a manufacturing partner and scaling up to production.

HotorNot Coffee Stirrer is trying to overcome a problem unique to their food-related project. A hot drink sensor that has to go in the drink itself needs to be food safe, as well as easy enough to clean between uses. A variety of components are discussed including a thermopile on a chip that has the advantage of not requiring contact with the liquid, but sometimes the simplest ideas can be the most effective as Bunnie reminds us that a cheap medical thermometer teardown can tell us a lot about appropriate parts for this application.

It’s another component choice problem that vexes PhalangePad, an input device that relies on the user tapping the inside of their fingers with their thumb. It’s a great idea, but how should these “keypresses” be detected? Would you use a capacitive or magnetic sensor, a force sensitive resistors, or maybe even machine vision? Here Bunnie’s encyclopaedic knowledge of component supply comes to the fore, and the result is a fascinating insight into the available technologies.

We all amass a huge repository of knowledge as we pass through life, some of the most valuable of which is difficult to pass on in a structured form and instead comes out as incidental insights. An engineer with exceptional experience such as Bunnie can write the book on manufacturing electronics in China but still those mere pages can only scratch the surface of what he knows about the subject. There lies the value of these mentor sessions, because among them the gems of knowledge slip out almost accidentally, and if you’re not watching, you’ll miss them.

This is the second in our series of Hackaday Prize mentoring sessions this year, but we have more already in the can and further sessions to record. We’re constantly looking for more participants though, so make sure if you haven’t already that you put your entry in for Hackaday Prize and check out the list of mentors who are here to share their knowledge and experience.

Your Masterclass In Product Design: Hackaday Prize Mentor Sessions

New to this year’s Hackaday Prize is a set of live mentor sessions and you’re invited! Being at the center of a successful product design project means having an intuitive sense in many, many areas; from industrial design and product packaging, to manufacturing and marketing. This is your chance to learn from those experts who have already been there and want to make your experience better and easier.

We want you to get involved by entering your own project into the Hackaday Prize; now is the time to tell us you’re ready to demo your project with a mentor. Hackaday Prize Mentor Sessions are happening every two weeks throughout the summer. In these video chats we’re inviting some promising Hackaday Prize entries to start off with a “demo day” type of presentation, followed by an interactive session with the mentor hosting each event.

It’s also important that this incredible resource be available to all, so these videos will be published once the mentor session wraps up. This is a master class format where the advice and shared experience have a beneficial effect far beyond the groups sharing their projects.

The 2019 Hackaday Prize focuses on product development. Show your path from an idea to a product design ready for manufacturing and you’ll be on target to share in more than $200,000 in cash prizes!

A Farmer’s Guide To Technology

One of the hardest aspects of choosing a career isn’t getting started, it’s keeping up. Whether you’re an engineer, doctor, or even landscaper, there are always new developments to keep up with if you want to stay competitive. This is especially true of farming, where farmers have to keep up with an incredible amount of “best practices” in order to continue being profitable. Keeping up with soil nutrient requirements, changing weather and climate patterns, pests and other diseases, and even equipment maintenance can be a huge hassle.

A new project at Hackerfarm led by [Akiba] is hoping to take at least one of those items off of farmers’ busy schedules, though. Their goal is to help farmers better understand the changing technological landscape and make use of technology without having to wade through all the details of every single microcontroller option that’s available, for example. Hackerfarm is actually a small farm themselves, so they have first-hand knowledge when it comes to tending a plot of land, and [Bunnie Huang] recently did a residency at the farm as well.

The project strives to be a community for helping farmers make the most out of their land, so if you run a small farm or even have a passing interest in gardening, there may be some useful tools available for you. If you have a big enough farm, you might even want to try out an advanced project like an autonomous tractor.

Tearing Down The Boss Phone

Poke around enough on AliExpress, Alibaba, and especially Taobao—the Chinese facing site that’s increasingly being used by Westerners to find hard to source parts—and you’ll come across some interesting things. The Long-CZ J8 is one of those, it’s 2.67 inch long and weighs just 0.63 ounces, and it’s built in the form factor of a Bluetooth headset.

A couple of months ago Cory Doctorow highlighted this tiny phone, he’d picked up on it because of the marketing. The lozenge-shaped phone was being explicitly marketed that it could “beat the boss”. The boss in question here being the B.O.S.S chair—a scanning technology that has been widely deployed across prisons in the U.K. in an attempt to put a halt to smuggling of mobile phones to inmates.

The Long-CZ J8 is just 2.67 inch (6.8cm) long.

I wasn’t particularly interested in whether it could make it through a body scanner, or the built-in voice changer which was another clue as to the target market for the phone. However just the size of the thing was intriguing enough that I thought I’d pick one up and take a look inside. So I ordered one from Amazon.

Bunnie And Snowden Explore IPhone’s Hackability

[Bunnie Huang] and [Edward Snowden] have teamed up to publish a paper exploring the possibility of introspection on the iPhone.

The idea is that phones are increasingly complex and potentially vulnerable to all kinds of digital surveillance. Even airplane mode is insufficient for knowing that your phone isn’t somehow transmitting information. The paper looks at the various radios on the iPhone, going so far as opening up the device and reading signals at each of the chips for cell, WiFi, Bluetooth, GPS, and NFC to determine whether the chip itself is doing anything, regardless of what the screen says. This introspection can then be used to be confident that the phone is not communicating when it shouldn’t be.

The paper goes on to propose a device that they will prototype in the coming year which uses an FPC that goes into the phone through the SIM card port. It would contain a battery, display, buttons, multiple SIM cards, and an FPGA to monitor the various buses and chips and report on activity.

Significant hacking of an iPhone will still be required, but the idea is to increase transparency and be certain that your device is only doing what you want it to.

Bunnie And EFF Sue US Government Over DMCA 1201

This morning Bunnie Huang wrote about his reasons for suing the US Government over Section 1201 of the Digital Millennium Copyright Act (DMCA).

The DMCA was enacted in 1996 and put in place far-reaching protections for copyright owners. Many, myself included, think these protections became far-overreaching. The DMCA, specifically section 1201 of the act which is known as the anti-circumvention provision, prohibits any action that goes around mechanisms designed to protect copyrighted material. So much has changed since ’96 — software is now in every device and that means section 1201 extends to almost all electronics sold today.

So protecting copyright is good, right? If that were the only way section 1201 was enforced that might be true. But common sense seems to have gone out the window on this one.

If you legally purchase media which is protected with DRM it is illegal for you to change the format of that media. Ripping your DVD to a digital file to view on your phone while on the plane (something usually seen as fair use) is a violation. Want to build an add-on for you home automation system but need to reverse engineer the communications protocol first? That’s a violation. Perhaps the most alarming violation: if you discover a security vulnerability in an existing system and report it, you can be sued under DMCA 1201 for doing so.

Cory Doctorow gave a great talk at DEF CON last year about the Electronic Frontier Foundation’s renewed push against DMCA 1201. The EFF is backing Bunnie on this lawsuit. Their tack argues both that section 1201 is stiffling innovation and discouraging meaningful security research.

If it’s illegal to write about, talk about, or even privately explore how electronics are built (and the ecosystem that lets them function) it’s hard to really master creating new technology. A successful lawsuit must show harm. Bunnie’s company, Alphamax LLC, is developing hardware that can add an overlay to an HDMI signal (which sounds like the continuation of the hack we saw from him a few years ago). But HDCP would prevent this.

Innovation aside, the security research angle is a huge reason for this law (or the enforcement of it) to change. The other plaintiff named in the suit, Matthew Green, had to seek an exemption from the DMCA in order to conduct his research without fear of prosecution. Currently there is a huge disincentive to report or even look for security vulnerabilities, and that is a disservice to all. Beneficial security research and responsible disclosure need to be the top priority in our society which is now totally dependent on an electronically augmented lifestyle.

Extremely Thorough Formlabs Form 2 Teardown By Bunnie

[Bunnie Huang] recently had the opportunity to do a thorough teardown of the new Formlabs Form 2 printer. It’s a long read, so just head over there and immerse yourself in every detail. If you want the cliff notes, though, read this but still go look at all the pretty pictures.

First, it’s a major upgrade with pretty much every component. The CPU is a huge step up, the interface went from monochrome to full color touch screen, the connectivity has been upgraded with WiFi and Ethernet, the optics are much better and safer, the power supply is integrated, there are lots of little improvements that handle things like bed leveling, calibration, resin stirring, pausing jobs, and resin refilling during a print. Bunnie practically gushes at all the features and impressive engineering that went into the Form 2.

You can compare the teardown of the Form 2 to [Bunnie’s] teardown of the Form 1 printer back in 2013.
