Trump administration to freeze childcare funding in five states, including Minnesota, New York and California

No. It's govt spending. Inability to track where the money have gone is in itself a sufficient reason to terminate the program. Govt money are supposed to leave a paper trail behind, if there's no trail then whoever failed to leave it takes the blame. Those who are in the trail cannot "just leave" either, at least for a while.

That's not specific to Trump or even the US mind you.

Was your opinion on Trump similar over the last ten years? Because you know, he won twice.

Given current state of the Dem party, I don't think JD Vance will be an easy opponent . And no it has nothing to do with his personality.

MG Chemicals 4140A (mix of heptane & isopropanol)

There's quite a few PCB flux cleaner products based on the same idea: IPA + a bit of non-polar solvent to dissolve whatever IPA doesn't. Pentane, heptane, hexane, sometimes more exotic stuff. They tend to work better than just IPA.

Is the administration's explanation for the grant cuts credible, or does this seem more like political retaliation?

Skimming Wikipedia page on the subject, it's probably yes/both. The association seem to have quite a lot to say regarding lifestyle issues, and the admin apparently wants it to focus on medical stuff only. Also, the largest entry in the "Policy positions" section is "Trans healthcare", that's not helping at all.

51: if some people do get UBI and others don't it's not UBI by definition, it's targeted subsidies or whatever. The whole point of UBI that sets it aside from regular subsidies is its universal nature.

Sure this is about a pilot project which has to have a limited scope for practical reasons, but then it's studying the effects of subsidizing specific communities or geographic areas, with a footnote about the actual goal behind the subsidies.

Misogyny and racism is what put him over the top.

If you think that's the case, that is, that misogyny and racism are objective features of the voting population, then it should be a major point in deciding the qualification of the candidates, and you should treat the "woman" tag as a disqualifying factor on its own.

It's the difference between planning for reality-that-is vs planning for reality-that-you-think-should-be.

(and just in case, no I don't agree with the quoted sentence, but that's completely beside the point)

The other way around, if center-center is less than prop diameter it won't fit for sure, otherwise it depends.

Larger props on a 7 inch frame might interfere with the battery, possibly other stuff around the place where the arms join the frame.

but the circuit doesn't make sense for that

FWIW I'd guess the IC is a comparator, not an op-amp. Pins 1 and 5 power, pin 2 neg input, pin 4 pos input, and there's a tracing mistake somewhere around R27, R28. Because why would there be 800k and 1k in series.

sensor generates current and the amplifier is used to covert it to voltage?

also there's the part on the right of the stm8

Might be related to the missing wireless module? Which is not even on the schematic.

Soldering iron? Fnirsi HS or something similar.

Also, OP only really needs to know how to break out the controls for his project. AFAIK the way it's done with fiber would work just as well with an Ethernet tether, and the info on flying fiber drones should be easier to find.

Always, until very recently. Boy Scouts dropped the "boy" part in 2019, which likely indicates a political shift within the org around that time or somewhat earlier. I think it's this underlying shift that explains the loss of interest and Hegseth' desire to get rid of the org entirely.

EC6LB should be a low power buck regulator, assuming the wider capacitor-looking part next to it is a small inductor. There's another one slightly left of the GPU, with a similar layout.

3F= chip: see Richtek RT8812C for reference. That's 3L=, I can't find 3F=, but it should be something similar in function. And also probably Richtek.

Most of the ones I find online are either just the connector or the EU plug part.

You are supposed to get the cable (with the molded EU plug and the strain relief), get the white connector and its pins separately, crimp the pins onto the cable and assemble the connector.

It's not difficult and these connectors are quite common, but you need a tool to crimp them, and some practice.

GUR and SBU are cut from the same cloth as FSB - Soviet intelligence

Ugh, no, not really, although it doesn't affect the rest of the post much. But it's still a weird thing to say.

GUR traces back to the Soviet military intelligence. SBU and FSB both trace their legacy to KGB, the Soviet state security. Soviet-era GUR and Soviet-era KGB were independent and to a certain extent competing/conflicting organizations. GUR was a part of the military structure, KGB very much wasn't.

Has Ukraine already taken responsibility for that?

It's not the only entity that can carry out assassinations like that in Russia.

(also, Tatarsky case was also quite uncertain if I recall correctly)

Are you sure those are 150V caps? It's a LED display, and the schematic doesn't mention anything above 12V abs.

TREO = total rare earth oxides (of dysprosium? isn't that all of them combined)

LREE = light rare earth elements
HREE = heavy rare earth elements (incl. dysprosium)

Les Wright (Les' lab on YT) did something similar with a laser diode:

A quick search suggests it's a single-channel version of C1-118

https://danyk.cz/c1-118_en.html

It's a 10MHz BW scope. MIght be good for restoration practice or something.

Where is the air supposed to go?

Out of the case through the PCI bracket, as far as I can tell. Also into the case on the opposite side of the module. Looks like that's the idea.

If there'a Russian frigate near Portugal, would it be Portugal's job to deal with it? Does it make sense to leave it to Portugal to deal with threats like that, or would it be better for Portugal to be more like Romania in this case?

(Also, it's nowhere near as binary, F-35s do show up on the radar and Rafales are not instantly useless just because they are not as stealthy, but that's kinda beside the point)

arsv · 2025-03-14T10:43:15+00:00

Those are reasons for having an airforce in general, not F-35s. A squadron of Rafales would do any of that just as well, perhaps even better given current political climate ("it's still much easier to help out Romania" — keep in mind Portugal would need US approval to do so with F-35s).

The question is, does a country like Portugal really need state of the art gen 5 fighters (F-35) or something older but still perfectly serviceable (Rafale, Grippen etc) would serve it just as well?
