Looks like an interesting software project, bringing powerful and cool libraries to the arduino ecosystem. Too bad they chose the "let's make a redundant copy of the pi zero-w (or another 10k boards out there) without any actual a

Yeah, so much more powerful..... And sooooooo much more challenging to secure. At least with microcontrollers, you (can) lock down execution of arbitrary code almost entirely, because Harvard architecture.

Logistics. A well equipped squad of marines would still eventually succumb to a gird of barbarians unless they could resupply.

To me, many worlds + time (as an inviolate observed vector) being merely a consequence of our inability to observe without moving foreward in time based on our entropic process driven cociousness, seems by far the most comprehensive explana

Depending on the magazine dimensions (single stack is hard) Reliable magazines can be largely 3d printed, as can the follower and the jigs used to bend piano wire into proper springs. The 3d.printed.mag will usually have less capacity than

Hybrid motors using solid fuels (plastic, rubber, cardboard, even sausage) and liquid oxidizer (typically nitrous oxide) are pretty common in hobby rocketry. These can be trivially made throttleable within a range by metering the NO2 flow.

Liquid electrode batteries transcend the "unfortunate tetrahedron" paradigm in many ways. By isolating the reactants from the reactor, "unlimited" storage and near-instant "recharging" (exchange of discharged f

Obviously, this is very sticky moral ground, and I don't claim to absolutely have the answers.... But I think there is merit to the idea of personage. Types of dolphins have been declared non-human persons, as have some primates, by se

I think the newish perception that risk is unacceptable plays a part. I'm glad to see the "safety above exploration" mindset giving way a bit. Accidents are going to happen. Pioneers in dangerous endeavors understand this. It

If this is actually a thing, it's probably 5 eyes that has the most invested in the tech. (Waves hands and puts on tinfoil hat) Check mate, atheists.

From a technical perspective I found this story compelling, so I tried out a simple hack to see if it were "possible". Using an attiny85 uC, a couple resistors, a cap, and a couple diodes I had laying around, I was able to wire up

I sometimes parse web data with uC based devices that are not capable of doing https with the memory space available. I appreciate the ability to use http when I need to.

If the clutch pedal was seemingly disconnected, that would be due to a loosened flare nut or a backed off cable end/clamp/adjustment. Likely Wouldn't even show up on a diagnostic scan (except possible low clutch hydraulic flu

Since adding noise is a critical part in many neural network training models, it is entirely possible that an at-hand source of randomness is highly useful. Drugs that reduce the accessibility of this randomness by biasing the signal pathwa

What you say is true for silicon, but Turing complete molecular machinery is already out there, we just have yet to master its intricacies. The nightmare AGI scenario likely involves molecular computing using a chemically optimal code-base

I realize that this is an outlier.... But I was raised in an aboriginal type environment (and my children's early experience was in a similar environment by risk) when a single episode of unruly behavior could result in serious injury

The 555 was great. These days I usually just drop in a 6 pin microcontroller though. Less external parts, cheaper, less environmental instability, much more operational flexibility, and often I can have it perform several circuit functions.

Passive components like a line conditioning resistor or cap could be changed out with an identical looking malicious component. Such a chip could perform effective MITM attacks against anything that talks on a serial line such as I2C, SPI,

The thing missing from this analysis is that on data bus lines like SPI, I2c and others there are "passive" components like resistors and capacitors used for signal conditioning and line bias. If one of these components were repla

Aaaahf. I used all of that stuff. All of it. Worse yet, last year I did a break-fix on a wlan installation at a Sears store... They had an operational token ring network still running their automotive department, along with a tan tower rock

Anyone measuring power will have the capability to bypass / defeat any external power filtering. To be of value this must be done at the die level.
