Have you heard that author Andy Weir has a new book coming out? Very exciting, we know, and according to a syndicated reading list for Summer 2025, it’s called The Last Algorithm, and it’s a tale of a programmer who discovers a dark and dangerous secret about artificial intelligence. If that seems a little out of sync with his usual space-hacking fare such as The Martian and Project Hail Mary, that’s because the book doesn’t exist, and neither do most of the other books on the list.

The list was published in a 64-page supplement that ran in major US newspapers like the Chicago Sun-Times and the Philadelphia Inquirer. The feature listed fifteen must-read books, only five of which exist, and it’s no surprise that AI is to behind the muck-up. Writer Marco Buscaglia took the blame, saying that he used an LLM to produce the list without checking the results. Nobody else in the editorial chain appears to have reviewed the list either, resulting in the hallucination getting published. Readers are understandably upset about this, but for our part, we’re just bummed that Andy doesn’t have a new book coming out.

In equally exciting but ultimately fake news, we had more than a few stories pop up in our feed about NASA’s recent discovery of urban lights on an exoplanet. AI isn’t to blame for this one, though, at least not directly. Ironically, the rumor started with a TikTok video debunking a claim of city lights on a distant planet. Social media did what social media does, though, sharing only the parts that summarized the false claim and turning a debunking into a bunking. This is why we can’t have nice things.

That wasn’t the only story about distant lights, though, with this report of unexplained signals from two nearby stars. This one is far more believable, coming as it does from retired JPL scientist Richard H. Stanton, who has been using a 30″ telescope to systematically search for optical SETI signals for the past few years. These searches led to seeing two rapid pulses of light from HD 89389, an F-type star located in the constellation Ursa Major. The star rapidly brightened, dimmed, brightened again, then returned to baseline over a fraction of second; the same pattern repeated itself about 4.4 seconds later.

Intrigued, he looked back through his observations and found a similar event from a different star, HD 217014 in Pegasus, four years previously. Interestingly, this G-type star is known to have at least one exoplanet. Stanton made the first observation in 2023, and he’s spent much of the last two years ruling out things like meteor flashes or birds passing through his field of view. More study is needed to figure out what this means, and while it’s clearly not aliens, it’s fun to imagine it could be some kind of technosignature.

And one last space story, this time with the first observation of extra-solar ice. The discovery comes from the James Webb Space Telescope, which caught the telltale signature of ice crystals in a debris ring circling HD 181327, a very young star only 155 light-years away. Water vapor had been detected plenty of times outside our solar system, but not actual ice crystals until now. The ice crystals seem to be coming from collisions between icy bodies in the debris field, an observation that has interesting implications for planetary evolution.

And finally, if like us you’re impressed anytime someone busts out a project with a six-layer PCB design, wait till you get a load of this 124-layer beast. The board comes from OKI Circuit Technologies and is intended for high-bandwidth memory for AI accelerators. The dielectric for each layer is only 125-μm thick, and the board is still only 7.6 mm thick overall. At $4,800 per square meter, it’s not likely we’ll see our friends at JLC PCB offering these anytime soon, but it’s still some pretty cool engineering.

LTSpice is a tool that every electronics nerd should have at least a basic knowledge of. Those of us who work professionally in the analog and power worlds rely heavily on the validity of our simulations. It’s one of the basic skills taught at college, and essential to truly understand how a circuit behaves. [Mano] has quite a collection of videos about the tool, and here is a great video explanation of how a bootstrap circuit works, enabling a high-side driver to work in the context of driving a simple buck converter. However, before understanding what a bootstrap is, we need to talk a little theory.

Bootstrap circuits are very common when NMOS (or NPN) devices are used on the high side of a switching circuit, such as a half-bridge (and by extension, a full bridge) used to drive a motor or pump current into a power supply.

From a simplistic viewpoint, due to the apparent symmetry, you’d want to have an NMOS device at the bottom and expect a PMOS device to be at the top. However, PMOS and PNP devices are weaker, rarer and more expensive than NMOS, which is all down to the device physics; simply put, the hole mobility in silicon and most other semiconductors is much lower than the electron mobility, which results in much less current. Hence, NMOS and NPN are predominant in power circuits.

As some will be aware, to drive a high-side switching transistor, such as an NPN bipolar or an NMOS device, the source end will not be at ground, but will be tied to the switching node, which for a power supply is the output voltage. You need a way to drive the gate voltage in excess of the source or emitter end by at least the threshold voltage. This is necessary to get the device to fully turn on, to give the lowest resistance, and to cause the least power dissipation. But how do you get from the logic-level PWM control waveform to what the gate needs to switch correctly?

The answer is to use a so-called bootstrap capacitor. The idea is simple enough: during one half of the driving waveform, the capacitor is charged to some fixed voltage with respect to ground, since one end of the capacitor will be grounded periodically. On the other half cycle, the previously grounded end, jumps up to the output voltage (the source end of the high side transistor) which boosts the other side of the capacitor in excess of the source (because it got charged already) providing a temporary high-voltage floating supply than can be used to drive the high-side gate, and reliably switch on the transistor. [Mano] explains it much better in a practical scenario in the video below, but now you get the why and how of the technique.

We see videos about LTSpice quite a bit, like this excellent YouTube resource by [FesZ] for starters.
