The New Essential Guide to Electronics in Shenzhen

December 16th, 2023

Some might remember a book I released in 2016, “The Essential Guide to Electronics in Shenzhen”. A lot has changed in the world since then, and Shenzhen is no exception.

There’s a new maintainer of the guide, Naomi Wu (@realsexycyborg), and she is crowdfunding an updated, new version with a snazzy red cover, called “The New Essential Guide to Electronics in Shenzhen”. While the technical Chinese terms haven’t changed much, a lot has changed in the culture and ways to do business; her new text gives pointers on how to engage on Wechat, digital etiquette in China, updated maps, and much more.

If you enjoyed The Guide in the past, or hope to visit the electronics markets in Shenzhen in the future, you can reserve your copy today.

Winner, Name that Ware October 2023

November 30th, 2023

The Ware for October 2023 is a Seiko DS-250 keyboard synthesizer.

Nobody guessed the exact make and model of the keyboard, but it was really entertaining to see the comment thread puzzle through the design. The dual 8049’s caught my attention too, as well as the lack of obvious DACs. I have some partial photos of the associated I/O board, and it also lacks an obvious DAC — mostly just generic mixer/amp/analog switch components on there, so I’d agree with the idea that the DAC could be integrated into one of the big Toshiba chips (or perhaps they are doing something with PWM).

I’ll give the prize to Cary Roberts for being the first to guess the general class of ware (congrats and email me for your prize!). Lots of attention to detail to what I had accidentally left in the background after the crop, I didn’t even notice the rollover diodes in the background until someone pointed it out!

Thanks again to JeffreyO for contributing these photos!

Regarding Proposed US Restrictions on RISC-V

November 6th, 2023

A bipartisan group of 18 lawmakers in the US Congress have recently amplified a request to the White House and the Secretary of Commerce to place restrictions on Americans working with RISC-V (see also the initial request from the Senate) in order to prevent China from gaining dominance in CPU technology.

The request is facially misguided; any restrictions would only serve to reduce American participation in an important emerging technology, while bolstering ARM’s position as an incumbent near-monopoly provider of embedded CPUs.

When the first report came out, I hoped it was just a blip that would go away, but with the broader bi-partisan group asking for restrictions, I felt I could no longer just stand by and watch: I am an active participant in the RISC-V ecosystem. I’m also subject to US law.

I did the one thing any American can do, which is write a letter summarizing my thoughts on the issue, and sending it to the White House, Department of Commerce, and the relevant members of Congress. Unfortunately, I don’t have a PAC, lobbyists or any sort of high-level connections to US politicians, so I don’t have much hope the letter will be received in time.

However, I do have a blog. I’m posting a copy of the letter I sent to the White House here, in far-flung hopes that maybe someone with more political connections than I might pick it up and send it on.

Finally, if you disagree with my stance or have a different perspective, I also encourage you to send a letter expressing your thoughts to various government officials. It doesn’t have to be “my way”, but a show of broad public interest in the topic may at least encourage policymakers to think a bit more carefully about the issue, and to hear out more perspectives.

The Letter

To President Biden and the White House staff:

Recently, a letter was sent to the White House and the Secretary of Commerce by 18 lawmakers asking how the US plans to prevent China “from achieving dominance in … RISC-V technology and leveraging that dominance at the expense of US national and economic security”.

I am a Michigan-born American with a PhD from MIT in electrical engineering. I’m also a small business owner who designs and manufactures electronics. I am writing to urge you to not place any restrictions on the sharing of RISC-V technology.

My products’ CPUs are based on the open source RISC-V standard. RISC-V’s openness specifically benefits small businesses such as mine. I get tools and designs from the open source community, and I contribute my improvements back to the pool. Barrier-free participation in this vibrant open source ecosystem keeps overhead low, allowing me to be competitive in the cutthroat hardware business.

Like the Internet, RISC-V is already a global phenomenon. There are already prolific contributions from the EU, India, China, and more [1]; the US is not the sole proprietor of RISC-V implementations. I use an implementation of RISC-V called the VexRiscv, which is developed in the EU. Any barrier for US persons’ participation will only slow American progress in developing and adopting this technology. It will have an effect opposite of that intended by lawmakers.

A further subtlety is that RISC-V is simply a standard. It defines a set of words used to tell a chip to do something, similar to how we rely on a dictionary to define the meaning of English words. Just as one can write secret documents using openly defined words, designs using the RISC-V standard can be proprietary, even if the standard is open. The benefits of open standards are so well established that the US has an entire agency – NIST – to promote American innovation and industrial competitiveness by publishing open standards.

Furthermore, it is not practical to police the use of an established standard: once a book is published, it is impractical to ensure that none of America’s enemies obtain a copy of it. This has long been a trade-off of American innovation philosophy: we can freely exercise our First Amendment rights to share ideas, creating a vibrant intellectual exchange, even at the risk of others benefiting from reading our textbooks, journals and patents.

I believe this trade-off has been in our favor. With every exchange – even with potential competitors – we learn more. Chilling our freedom of expression to achieve administrative outcomes is a page out of other more oppressive regimes’ playbooks: it is fundamentally un-American to restrict the flow of ideas.

In summary, any restrictions placed on US persons sharing RISC-V technology would only serve to diminish America’s role as a technological leader. Over-broad restrictions could deprive educators of a popular tool used to teach students about computers on American campuses, for fear of also accidentally teaching to an embargoed entity. And even narrow restrictions on RISC-V could deprive US tech companies with any potential exposure to the Chinese market of access to a cost-effective, high-performance CPU technology, forcing them to pay royalties to the incumbent near-monopoly provider, ARM Holdings plc – a company that isn’t American. This weakens American competitiveness and ultimately harms the US’s best interests.

If the administration agrees that RISC-V is a technology so critical to US economic and military interests that it deserves special attention, instead of trying to restrict its expression with a federally-mandated licensing regime, it should invest in programs to develop more home-grown American RISC-V chip maker success stories. It is already within the four corners of existing US legal framework, and the RISC-V contractual framework, for companies to choose to develop proprietary implementations of RISC-V CPUs. The US has strong precedents for companies navigating the boundaries of open standards and finding success without the need for federal guidance: Intel and AMD are American industrial juggernauts built around proprietary implementations of an otherwise openly documented “x86” computer standard. What the US needs is an American answer to ARM Holdings plc’s monopoly, and that answer comes from investing in US companies that embrace RISC-V.

President Biden, I urge you: have faith in American innovation. Have faith in American values. Do not place any restrictions on the sharing of RISC-V technology. We can work together to build more US chip maker success stories, while embracing the American value of freedom of expression!

Very truly yours,
