The train has to have an inverter anyways to vary its rpm, and I assume that the motor runs on less than 15 kV anyways. So it could conceivably be done without a separate DC-DC step-up converter, but I wouldn't know for sure.

These are new-ish to a point where only train nerds know about them, but they're also old enough to be a fully certified COTS product that you can just buy the way that you buy your normal trains also.

Considering how fast that industry moves, I think that is saying something.

More to the point, why does that shop advertise to anybody other than gov agencies with deep pockets and a strong interest in remote sensing?

That makes for a 20h energy storage at full power, and a big enough power reserve to recharge that storage during the day while delivering at full power. Likely a reserve for morning/evening/clouds. Easy to add more storage.

So, it's a 2 GW power link, not a 20 GW power link. It's a 20 GWp site, and that's impressive too. At 200 Wp (STC) per sq m, that is 100M m², or a 6 mile square not counting any access roads. Huge, but if five of these is all it takes to power Singapore, then I guess we're looking at a bright future.

PEAQ is an algorithm and scoring system that takes psychoacoustic modeling into account. When I looked into this more than ten years ago, I managed to find a command line utility called pqevalaudio or something that I could just use to assign a score to a file.

It is mostly about "strong" vs "weak".

Remove the tires from two old bicycles to run them on rails, build a gantry between them mounted to seatposts and handlebars. Probably drive it with chains on winches for robustness.

Use movable wall elements so that the pick and place machine can set up both shade and increased illumination. Maybe have portable rain protection too. Maybe deploy close-up UV and IR lamps.

I'd like to know the max size that a single gantry can serve, see how high its utilization can be.

My guess is that it all can pay off once it's big enough. I just don't know where that point is. 100ft long? 200ft? 300? And 20ft wide?

These robots will not help avoid famine, but they will help rich first world people be more cognizant of food and agriculture. Which in turn will help them make better choices with the food they buy. This can only work against calory-dense inudstrial food, which arguably is the larger problem than efficiency in large parts of the world.

Our supplier advertised a sensor, which we found eventually on the other end of the PCB. The reaction time would have been five or ten minutes if at all, essentially the whole device would burn down and eventually it would take the sensor with it.

Turns out, the sensor would had to sit directly opposite the FET on the PCB, and there had to be a plugged via going straight through for sufficient thermal coupling. A lot of the physics boils down to simple aspect ratio, and normal vias are really thin.

(The real solution would have been putting the sensor on an FPC, and to glue onto the transistor. The real real solution was to make sure the part didn't blow up in the first place, which was much easier to do.)

Have auto translate switched off if you value those visitors who actually read stuff, even if the metrics give it a 20% advantage.

If there's one thing we were able to learn with 100% certainty over the last couple years, it is this. I still think it'll have to be transparent, or at least Google Glass like, to achieve mass adoption.

If you hate the design, don't let your arguments rely on a bad implementation of what you hate. Make them work with a perfect one.

This topic needs careful consideration and I should use more brain cycles on it. Please insert another coin.

And I do like the "For you" feed. I do want to read random people's tweets, I keep finding solid reading material that way. But that means I have to block a significant portion of all of twitter. I'd say after about 50k to 100k accounts blocked it gets better. Less for other languages.

There are browser plug-ins that block all accounts that follow a given account. Those are great. So, whenever I find a MAGA guy with Russian grammar structure, an NFT scammer, a bible quote proselytizer, or a Tesla bag holder, I just block everybody following that account.

It takes about a day or two of doing, but then it works great. Best done when sick, works well with headaches and a fever. But now my twitter experience is about as good as it was 2017.

With good wireless, the setup is reasonably performant, fast enough to move the mouse and type fluently. Certainly slower than USB monitors, but ideal to put some reading material on one screen (PDF or a browser window), and a text editor on the other while still using the main screen.

I also use them in portrait orientation 10:16, which is nice. Cheapest and most portable triptych setup there is, I guess.

Partitioning off a small section of the drive feels very 160 GB SCSI "Let's only use the outer sectors".

In that case I suggest more exposure to viewpoints that aren't similar to your own.

In IT that is called a spec bump, not a disruption.

This reads like someone read Schopenhauer, and now they're trying to sound smart without spilling their secret.

Then there are those who say "every wire complicates compliance testing, every automation complicates failure modes, every custom part complicates supply chain", and they are the ones that prefer in-house mechanical parts with conservative materials and tooling.

I think it's an age thing, maybe it's a hipster vs greasy-elbows-shop-floor guy thing, but honestly it can be hard to tell who's right.
