Huang attended the Massachusetts Institute of Technology in 1992, earning a Ph.D in electrical engineering in 2002. He stated that he had 'flipped a coin' to determine whether to pursue biology or electronics. Huang is also a member of the Zeta Beta Tau fraternity.
The nickname bunnie is short for vorpalbunnie, a reference to the creature in both Monty Python and the Holy Grail and Moria, that he used as a BBS screen name.
Huang was the hardware lead at Chumby; his responsibilities included the design and production of Chumby devices, as well as the strategic planning and ecosystem development of the broader Chumby hardware platform.
He has completed several major projects, ranging from hacking the Xbox, to designing the world's first fully integrated photonic-silicon chips running at 10 Gbit/s with Luxtera, Inc., to building some of the first prototype hardware for silicon nanowire device research with Caltech. Huang has also participated in the design of wireless transceivers for use in 802.11b and Bluetooth networks with Mobilian, graphics chips at Silicon Graphics, digital cinema codecs at Qualcomm, and autonomous robotic submarines during the 1999 competition held by the AUVSI that the MIT team won. He is also responsible for the "un-design" of many security systems, with an appetite for the challenge of digesting silicon-based hardware security.
Huang was scheduled to appear as an expert witness in the trial United States v. Crippen to determine whether or not modding an Xbox violates sections of the DMCA. The case was dropped suddenly on the third day of trial before the jury sat by the US federal authorities who had initiated the action. The case was dismissed before Huang was called to give testimony.
He also created the open hardware Safecast Geiger Counter Reference Design, as a volunteer effort in response to the 2011 Tōhoku earthquake, tsunami, and ensuing meltdown of Fukushima Daiichi. A project in collaboration with Jie Qi of the MIT Media Lab is Circuit Stickers, a peel-and-stick circuit system for crafting electronics. Huang was interviewed on Dave Jones' The Amp Hour in episode #84, where he talked about his electronics work in China and reverse engineering.
Huang is a member of the advisory board for Crowd Supply, the crowdfunding platform that he used for Novena and The Essential Guide to Electronics in Shenzhen.
Huang has a long and noted history with the reverse engineering and hacking of consumer products. His 2003 publication Hacking the Xbox: An Introduction to Reverse Engineering was one of the first published works regarding the reverse engineering of a high end consumer product. He faced significant legal pressure from Microsoft to not reveal the details of his exploits, and the book itself reveals that he had received a letter from MIT, where he was at the time a student, informing him of their disavowment of any association with his project. Additionally, his publisher John Wiley & Sons had rescinded their intent to publish the book.
In part because of this response by MIT to his work, when the Institute was again put at the forefront of controversy in their handling of the lawsuit brought against Aaron Swartz, and his subsequent suicide, Huang released the book for free through No Starch Press, remarking that "Without the right to tinker and explore, we risk becoming enslaved by technology; and the more we exercise the right to hack, the harder it will be to take that right away".
In 2005, Huang worked with a team from the Electronic Frontier Foundation to develop code that interprets printer steganography markings.
Huang created the NeTV in 2011, which was the first known public use of the High-bandwidth Digital Content Protection (HDCP) 'master key'. The device uses the master key to implement a video overlay on existing HDCP-protected links, in a fashion which purportedly does not violate the DMCA. Both the hardware and firmware for the NeTV are openly available under the CC-BY-SA license.
He has also used reverse engineering techniques to reveal why certain MicroSD cards are poor in quality. In 2013, he presented results in collaboration with fellow Singapore developer Sean 'xobs' Cross revealing methods to load arbitrary code into microSD cards via backdoors built into the embedded controller.
On 21 July 2016, Huang and Edward Snowden, in a talk at MIT Media Lab’s Forbidden Research event, published research for a smartphone case, the so-called Introspection Engine, that would monitor signals received and sent by that phone to provide an alert to the user if their phone is transmitting or receiving information when it shouldn't be (for example when it's turned off or in airplane mode), a feature described by Snowden to be useful for journalists or activists operating under hostile governments that would otherwise track their activities through their phones.
In 2013, Huang announced that he, again in collaboration with Cross, was at work developing a laptop called the Novena. The laptop is the first of its kind, in that the hardware and software are entirely open and only include components where the manufacturing companies do not require non-disclosure agreements to obtain the documentation necessary for design. In addition to the normal laptop components, the Novena motherboard also includes an FPGA, dual Ethernet ports, a three-axis accelerometer, and easily augmentable hardware. On May 7, 2014 the Novena's crowdfunding campaign reached its goal of $250,000 and went on to raise a total of $722,880 without taking subsequent pre-orders into account.
Huang is a contributing writer for MAKE magazine, as well as being a member of their technical advisory board. He has also written for Gizmodo and IEEE Spectrum.
He has also written extensively about manufacturing in China. In March 2016, Huang successfully completed the crowdfunding campaign for his book The Essential Guide to Electronics in Shenzhen, a manual written to enable the English speaking electronics community to be able to navigate China's Huaqiangbei marketplace in Shenzhen, widely regarded as one of the world's premier electronics marketplaces and production hubs. He also appeared in Wired's 2016 documentary Inside Shenzhen: The Silicon Valley of hardware.
In July 2016, Huang became a plaintiff in a lawsuit filed by the Electronic Frontier Foundation (EFF) that challenges the Digital Millennium Copyright Act (DMCA). In the complaint, the EFF argue on behalf of Huang (and his company AlphaMax LLC.) that the "anti-circumvention" and "anti-trafficking" provisions of the Digital Millennium Copyright Act threaten free speech.
In 2007, Huang received the Lewis Winner award for Best paper at ISSCC 2006 (A 10Gbit/s photonic modulator and WDM MUX/DEMUX integrated with electronics in 0.13 um SOI CMOS, Solid-State Circuits Conference, 2006. ISSCC 2006. Digest of Technical Papers. IEEE International)
In September 2012, Huang received the 2012 EFF Pioneer Award for his work in hardware hacking, open source and activism.
