Came here to mention this. I've had a lot of fun putting up stealth repeaters in trees to build out the Meshcore network. One or two nodes in critical places can light up dozens of…

> 2 kW socket > kilometers It's much more tenable in the 220V world, for sure. But even if you only charge during road trips, the quality of the chargers during those road trips ma…

I'm not making any representation of how common this is - just saying that unless all those conditions apply to you, you will eventually have cause to care about the quality, avail…

The vast majority of what you're running from RV DC are things like lights, fans, phone chargers, and other cigarette-plug-adapter type devices. My RV has a 12V DC fridge. For anyt…

I laughed so loudly it startled the cat

> This method achieved an energy conversion efficiency of about 130%, exceeding the traditional 100% limit I am extraordinarily confident that it did not. > In practical terms, thi…

The infrastructure in question is DC fast chargers. Yes, you can charge at home if you have a house, with a parking space reachable with an EVSE, and your commute is short enough t…

The lesser-known instance of this is RV power. When you're running off small batteries and solar, you want to make the best use of the watt-hours you have, and that means avoiding …

You might be surprised. Various games have come with both. One iteration (the 3DS remake of Gold/Silver) even came with a pedometer that allowed you to level up by walking around: …

Philips Hue, and Zigbee direct-binding in general, can achieve this if you're willing to use their wall switches. Still works if the hub is offline. Depends on your definition of "…

I have almost everything in my house HA-automated, but anything touching the water supply is all on dumb physical valves and electrical timers. If my light switches don't work, tha…

Further to what's listed elsewhere: A RAM chip takes several months to make, starting from an empty silicon wafer. Each chip takes 8-10 weeks to go through the process of lithograp…

They have something like 2 stars on Goodreads. Imagine that as a fairly accurate product review score - if they were Amazon products, they'd be somewhere between "obviously counter…

There's a sequel to Andromeda Strain? ... Yeah, better off forgetting this information.

A mere month after Pretenders to the Throne of God. You have to admire his output.

DO NOT READ THE SEQUELS One of the few cases where they actively ruin the first book, to the extent you take them as true sequels. Clarke basically licensed his name and plot to Ge…

"Wonder" might be the wrong way to describe it, but Blindsight by Peter Watts gave me the same feeling of "this is incredibly alien and I have no idea what will happen next". Other…

Are you going to return it for an M5?

Almost nowhere do you see the sun directly overhead at noon, even during Standard Time. The differences can be quite stark: https://24timezones.com/cms-static/images/uploads/solart…

For one non-core part of their chip. > The GPU die will remain with TSMC

Dimming. And even without that, the "continuous DC" is usually provided by switch-mode power supplies that themselves have a PWM ripple. How much depends on the quality of the supp…

Are you sure? I took 6.814 Database Systems back when Stonebraker taught it, and it's still being taught as 6.5830. The first problem set was a nontrivial crash course in SQL, usin…

You may want to look into an AVR (audio/video receiver), also known as a home theater receiver. Aside from powering speakers, that's their core function: connect a variety of input…

It's interesting to see that MIT is still like this. Canonically, there were no classes that taught programming per se: if you needed that, there were (often volunteer-taught) cour…

And if you get bored of that, you can flip the RAM for more than you spent on the whole system!
