> I wonder if you can make an unpickable lock with MEMS I'm not sure what you mean. MEMS are generally tiny and I'm not sure why you'd need a ~1mm safe? But MEMS relay switches, wh…

> I always wondered why you needed gearing mechanisms in a micro machine. Has there ever been a practical application for gears in MEMS? IIRC, Sandia Lab's SUMMiT V process (the so…

> I wonder if you can make micro machines at this level? The MEMS thing. At this size range, though state-of-the-art MEMS (mechanical vibrating frequency filters for RF receivers i…

There are other ways to make PCBs with a 3D printer: Instead of etching copper, some people directly print the circuitry with a solder extruder [1]. The idea's been around for a wh…

I'll second (third?) LineageOS + microG! Full ROMs combining both are available [1] (OS updates often seem to have to be installed manually, but are supported on popular phones for…

Lots more detail for the uninitiated: The most complex parts of phones and computers (e.g., the CPU) are integrated circuits (ICs)[0], which are (nowadays) billions of nanometer-si…

To elaborate: A single IC die (a "chiplet" when stacked on others) is made of a layer of transistors and wiring up to several hundred nanometers thick on top of a much thicker (sev…

Some other open Slack alternatives I know about include: Matrix[1]: maybe the most impressive. A chat _protocol_ with multiple server and client implementations, gateways to everyt…

Digital notebooks (Electronic Lab Notebooks --- ELNs) exist, but haven't caught on yet. Many researchers often need to be able to note down arbitrary diagrams, not just text, in re…

According to the linked statement from the UC Office of Scholarly Communications [1], "No matter what happens moving forward, UC scholars will still be able to use ScienceDirect to…

Usually, CAD programs are written for just one of several domains, outside of which they don't work as well: - Fusion360/SolidWorks/Onshape/Catia/NX are engineering CAD programs. T…

Other well-known 3D printer technologies include: - Fused deposition modeling (FDM): the typical plastic filament-extruding hobbyist printer. Low resolution, but fast and creates v…

This post is very well written! I like the colloquialism, exhaustive list of experiments (both successes and failures, to better educate others), future work and call to action, an…

IIRC, Syncthing is decentralized P2P and synchronizes standard tree(ish) filesystems (like most similar projects). Perkeep does away with the filesystem and instead uses a blob-bas…

A (non-exhaustive) list of hobbyist-accessible engineering CAD programs I can recommend: - Fusion 360 (Windows/Mac) (free for hobbyists) can do complex many-component robots or sim…

> World-class accuracy of 1.96 meters Good for WiFi/IMU-based indoor (phone-based) position tracking, I believe. For more accuracy, especially for robotics, etc., Pozyx [1] claims …

"I tried replacing Android with Lineage OS on a old phone I had. Whilst that meant I didn’t have any Google Apps on my device, it was still Android underneath. Also many apps kept …

"Reservoir computing" taken very literally: wave interference in a bucket of water computed a simple speech recognition task (differentiate "zero" and "one") [1]. [1] https://link.…

> And I'll bet you all my bitcoin the experiment data was not collected during any year from 2008-2012. From the paper, data was collected starting from January 23, 2013 for roughl…

Paper here [1]. Two-photon lithography from Nanoscribe [2] is used to make the color-producing nanostructures. This method can make arbitrary 3D structures but currently has a ~100…

It's a manufacturing limitation. Integrated circuits are nearly universally built via photolithography [1], which only makes flat 2D layers. Stacking many, many layers for 3D circu…

The IPFS [1] is close to this. Websites (and all other resources) are P2P hosted with a distributed hash table. For example, there's an reasonably uncensorable Wikipedia mirror [2]…
