That (chinook-style solution) only works if both rotors are the same size and speed.

Perhaps Sikorsky’s tethers to the ground worked around the problem for that photo anyway. Not sure.

Really, Penfold.

Sounds like they’re slowly recovering from an injury and see returning to office as an accomplishment. Take it easy friend, little steps are stronger than big steps.

Every news website is covering it. I think I’ve spotted most of 10 articles around the place.

The law of well-marketed unreleased goods dictates that this vehicle is not going to meet any of the promises mentioned in the articles. I hope to be proven wrong, but just like video games: don’t pre-order, wait for it to come out and be reviewed.

Thankyou border force for keeping this nuclear threat away from our shores. I hate to think what a growing market of periodic table and sample collectors could do to our great country.

I suspect that you need to think of the 3 B->E voltages as inputs (OR’d with each other) and the C->lowestvoltageE path as the output. All of them are operating in linear mode too, I think one of them is a low-gain follower whilst others have a lot more gain. Maybe.

Nope, bottom right and top middle >:D

Oh my god I’ve forgotten what a base is. This transistor is doing my head in.

I don’t want my children influenced by this. “Dad why does your transistor only have 3 legs?”. And I had only just rid the house of dual-gate mosfets too!

I only know what wikipedia tells me about these things, I’ve never played with one. I also have no clue yet what it does in this circuit.

3 emitters and 2 collectors.

The headline and text of this article were amended on 24 March 2025 after the Guardian was notified of a significant calculation error in the Queensland Conservation Council research. An earlier version said the dams that supply the proposed Callide and Tarong nuclear plants “could not access enough water” to cool them in the event of a meltdown; our article has been amended in line with the organisation’s revised analysis.

That’s a CH340G, it has an in-built 3.3V regulator. But there is no external regulator on the board.

Maybe the chip is running off its internal 3.3V, but the board designers put a tie-up resistor on one of its pins to 5V, which results in the weird 3.9V. Dunno. Try attaching a 1K resistor between that pin a GND, see if that makes the problem disappear.

The 5.3V is from your computer, that’s not the fault of the USB UART.

3.2V is perfectly acceptable for a 3.3V rail.

The 3.9V is a bit weird. Can you post a photo of your USB UART board? Maybe the main chip has an inbuilt 3.3V regulator separate to the external one.

Stand back, I’m carrying a budgie smuggler.

It’s holding a hammer!

There are some youtube videos of people machining them (sadly my browser does not support smell). Looks like you treat it like any other solid material: hobb or mill the teeth. This is much more expensive than 3d printing.

You might be surprised by your 3d printed gears. If you keep the detail size large they work really well, but backlash is definitely an issue.

I provided a HTTP link not a HTTPS link, I didn’t even know there was a (broken) HTTPS version of this site. Your browser must have some setting or addon that auto-redirects to https versions of sites even when the site doesn’t request it.

I swear that I read that white lead oxide is water soluble, thus happily sticks to your fingers and then gets on your food. I must be misremembering.

Maybe it was something about the solid lead object turning into an (oxide) powder that can then be easily ported as tiny particles on greasy hands? Hearsay science and safety information from me today :)

The fun thing about Pb is it’s relatively safe in pure form. Unfortunately the oxides that appear on its surface are water soluble and love entering our bodies.

Just looked this up, apparently I’m completely wrong. Maybe I was thinking about lipid compatibility? Not sure now.

Welcome to security news theatre :(

I don’t think espressif would bother suing, these kind of misshapen claims get constantly made against popular projects all of the time. It’s just unusual to see so much coverage about this particular one.

Not so say that externally attackable vulnerabilities in an ESP32 don’t exist, they might. Bluetooth devices have an awful track record. But making them up doesn’t help the world.

I happily ran THUGPRO under wine, so I assume rethawed would be the same. Dunno.

Where am I even supposed to buy it if I wanted to, which I don’t really,

Looks like it’s abandonware. Yeah, publisher dropped the ball.
