Books You Should Read: Prototype Nation

Over the years, I’ve been curious to dig deeper into the world of the manufacturing in China. But what I’ve found is that Western anecdotes often felt surface-level, distanced, literally and figuratively from the people living there. Like many hackers in the west, the allure of low-volume custom PCBs and mechanical prototypes has me enchanted. But the appeal of these places for their low costs and quick turnarounds makes me wonder: how is this possible? So I’m left wondering: who are the people and the forces at play that, combined, make the gears turn?

Enter Prototype Nation: China and the Contested Promise of Innovation, by Silvia Lindtner. Published in 2020, this book is the hallmark of ten years of research, five of which the author spent in Shenzhen recording field notes, conducting interviews, and participating in the startup and prototyping scene that the city offers.

This book digs deep into the forces at play, unraveling threads between politics, culture, and ripe circumstances to position China as a rising figure in global manufacturing. This book is a must-read for the manufacturing history we just lived through in the last decade and the intermingling relationship of the maker movement between the west and east.

Books You Should Read: Red Team Blues

Martin Hench really likes playing on the Red Team — being on the attack. He’s a financial geek, understands cryptocurrency, understands how money is moved around to keep it hidden, and is really good at mining data from social media. He puts those skills together as a forensic accountant. Put simply, Martin finds money that people want hidden. Against his better judgment, Marty does the job of a lifetime, and makes an absolute mint. But that job had hair, and he’s got to live through the aftermath. It turns out, that might just be a challenge, as three separate groups want a piece of him.

Red Team Blues, a work of fiction by [Cory Doctorow] about cryptocurrency, trust, finance, and society as a whole. When [Doctorow] offered to send us a copy to review, we jumped at the chance, and can give it a hearty recommendation as a fun and thoughtful tale. The moral seems to be that while everyone plays the sordid finance game, the government should really work harder to disentangle the mess, but maybe we would do better if more people opted for integrity. There is also a real point to be made about the dark side of cryptocurrency, in that it enables crime, ransomware, and money laundering on a global scale. For all the pluses for privacy and anonymity, there’s some real downsides. The characters spend most of the book wrestling with that dichotomy in the background.

The book took something of a moralizing turn just over halfway through. Which, depending on your viewpoint, you’ll either really appreciate, or have to hold your nose a bit to get through. But the suspense pulls the reader through it, making for an overall enjoyable read. As an added bonus, you might end up with a better mental image of how the pieces of digital privacy, finance, and the real world all fit together.

The book has all the fun references to Tor, Signal, Bitcoin, and computer history you could want. And the central MacGuffin is an interesting one: a cryptocurrency that runs on proof-of-secure-enclave, eliminating the ridiculous power consumption of proof-of-work schemes. All of this with some rich Silicon Valley lore setting up the background. Our conclusion? Two wrenches up.

Modern CO2 Laser Reviewed

If you’ve got a laser cutter, it is highly probable that it uses a laser diode. But more expensive machines use a carbon dioxide laser tube along with mirrors. There was a time when these lasers came in two flavors: very expensive and amazing or moderately expensive and cheaply made. However, we are seeing that even the moderately expensive machines are now becoming quite advanced. [Chad] reviews a 55-watt xTool P2. At around $5,000, it is still a little spendy for a home shop, but it does have pretty amazing features. We can only hope some less expensive diode lasers will adopt some of these features.

[Chad’s] video that you can see below attempts to recreate some of the amazing things xTool did on their product introduction live stream. He was able to recreate most, but not all of the results. In some cases, he was also able to do better.

FNIRSI Vs Rigol: An Alternate View

We’ve heard of the FNIRSI 1014D scope, but we’ve had the impression that it might not be a great scope, although it is economical. [Learn Electronics Repair] had heard from another YouTuber that it was “a piece of junk.” However, he wanted to look at it compared to another inexpensive scope, the Rigol DS1052E. His results were different from what we usually hear. To be clear, he didn’t think it was a perfect scope, but he did find it very usable for his purpose.

The 46-minute-long video does more than just a casual look. He uses both scopes in some real-world measurements. If you are in the market for a scope in this price range, it is worth the time to watch.

A Miniature MNT For Every Pocket

Last time Hackaday went hands on with a product from German company MNT, it was the Reform laptop; a full size computer with a full feature set and fully open source design. Now they’re back with the same value proposition and feature set crammed into a much more adorable (and colorful!) package with the MNT Pocket Reform. If you want the big Reform’s open source philosophy in a body fit for a coat pocket, this might be the computing device for you.

To refresh your memory, MNT is a company that specializes in open source hardware and the software to support it. They are probably best known for the Reform, their first laptop. Its marquis feature is a fully open design, from the mechanical components (designed with OSS tools) to the PCBAs (designed with KiCad) to the software (designed with, uh, software). When originally shipped that product packed a DIMM-style System On Module (SOM) with a default configuration containing a quad core NXP i.MX8M Quad and 4GB of RAM, as well as mini PCIe Card and M key m.2 2280 slots on the motherboard for storage and connectivity. That computer was designed to be easily serviceable and included a plethora of full sized ports along with easy to source cylindrical battery cells. The Pocket Reform takes the same intent and channels it into a much smaller package.

Glove80 Keyboard Sure Fits Like One

If you’re what one might call unlucky, there comes a point in your life when you need to switch to a keyboard that’s more ergonomic than your average rectangle. A little prevention goes a long way, though, and there’s no time like the present to go ergo. Why not? You have everything to gain, from long-lasting comfort to satisfying key presses.

The only problem is that most severely ergonomic keyboards just aren’t portable. At this point, we all know how much I love my Kinesis Advantage, and how I wouldn’t be able to write the Keebin’ column or even a grocery list without it. I have two now, and I take the ugly, yellowed, sticker-bombed one with me out into the world. But as much as I love it, I would really dig a a slimmed-down version that’s just as comfortable, perhaps more so. Well, move over, Kinesis, because you’ve got stiff competition in the form of a flexible little two-piece called the Glove80.

You may recall that there was a Kickstarter for this keyboard about a year ago. I was pumped about it then, and I still am. Here’s why:

Hands-On: NVIDIA Jetson Orin Nano Developer Kit

NVIDIA’s Jetson line of single-board computers are doing something different in a vast sea of relatively similar Linux SBCs. Designed for edge computing applications, such as a robot that needs to perform high-speed computer vision while out in the field, they provide exceptional performance in a board that’s of comparable size and weight to other SBCs on the market. The only difference, as you might expect, is that they tend to cost a lot more: the current top of the line Jetson AGX Orin Developer Kit is $1999 USD

Luckily for hackers and makers like us, NVIDIA realized they needed an affordable gateway into their ecosystem, so they introduced the $99 Jetson Nano in 2019. The product proved so popular that just a year later the company refreshed it with a streamlined carrier board that dropped the cost of the kit down to an incredible $59. Looking to expand on that success even further, today NVIDIA announced a new upmarket entry into the Nano family that lies somewhere in the middle.

While the $499 price tag of the Jetson Orin Nano Developer Kit may be a bit steep for hobbyists, there’s no question that you get a lot for your money. Capable of performing 40 trillion operations per second (TOPS), NVIDIA estimates the Orin Nano is a staggering 80X as powerful as the previous Nano. It’s a level of performance that, admittedly, not every Hackaday reader needs on their workbench. But the allure of a palm-sized supercomputer is very real, and anyone with an interest in experimenting with machine learning would do well to weigh (literally, and figuratively) the Orin Nano against a desktop computer with a comparable NVIDIA graphics card.

We were provided with one of the very first Jetson Orin Nano Developer Kits before their official unveiling during NVIDIA GTC (GPU Technology Conference), and I’ve spent the last few days getting up close and personal with the hardware and software. After coming to terms with the fact that this tiny board is considerably more powerful than the computer I’m currently writing this on, I’m left excited to see what the community can accomplish with the incredible performance offered by this pint-sized system.
