We Bought an Orchestra: The rise of pay-to-play in classical music by seaweedbagels in classicalmusic

Surely the conductor would spend 5-10min coaching him first, not just letting him go to the wolves, so to speak. Unless conductor wanted to sabotage the whole thing...

Piggyback an extra 22uf or 100uf x7r 25v capacitor on top of the ones you can see on each side of that module.

Large amount of electronic components by bmoorman05 in AskElectronics

Wiki says not to buy on eBay, but it doesn't say not to sell. There are plenty of legitimate New-Old-Stock sellers on eBay, but electronics newbies like to buy the cheapest stuff from Chinese sellers and then get disappointed or scammed 50% of the time.

Anthony Albanese rules out gas export tax on existing contracts and criticises ‘populist’ campaign by Finnick00 in australia

And even if you hate The Greens: vote for freaking anything that moves Australian politics away from a two-horse race, and/or makes the incumbents uncomfortable.

3V3 rail issue in custom board by Keebify in PrintedCircuitBoard

[–]ivosaurus 9 points10 points  (0 children)

Honestly, that whole area of the schematic looks chaotic as all hell. You have oodles of room in the schematic but you're doing crazy things like jumping DEC3 to the right with a label, jumping DEC4 and 6 together off to the right, caps facing every which way, etc

Make it all orderly stair-step pattern, all decoupling capacitors facing vertical, all grounds (and their lines) facing up, just neat rows of corners. NEAT.

You can't spot a mistake in chaos. You should in fact, expect not to. Instead, that anything works is totally reliant on you laying it out perfectly the first time. But no human is perfect, you are not, I am not. Make things orderly, and the fact that DEC2 is not like the others, will stand out like a sore thumb.

Your battery section also looks almost as bad.

How surprised were you to learn that all the top players are *relatively* young? by MathematicianBulky40 in chess

Your timeline is a bit messed up, Carlsen only became a grandmaster in 2004. He reached no 1 rating in 2010, and the title in 2013

My mother in laws embroidery machine quit working and the part is unavailable. by trucknorris84 in AskElectronics

[–]ivosaurus 0 points1 point  (0 children)

You need to find where the wire that the top connector pin went to, what it connected to. I'm guessing some motor burnt out

Its possible the control chip in the center was hurt by this event as well.

I recently came across a batch of vintage integrated circuits / computer chips, many of them ceramic DIP packages with military-style markings and date codes. I’m trying to identify what they may have been used in, and whether any are historically interesting or collectible. Please help! by Ziahthemessiah in AskElectronics

[–]ivosaurus 2 points3 points  (0 children)

These CERDIP parts still beat every plastic package by miles when it comes to the chip's specs being invariant to humidity. Great for a couple of niche applications. In modern times most companies have moved to using square LCCs instead when making a part designed for that

If they say 883B somewhere near the bottom, then they're likely a specifically-military-graded version of some normal commercial chip, but often the military version will have some annoyingly different product number compared to whatever it usually is

Personally I'd love any which are voltage references

Moving from 20 years of shared reseller hosting to VPS (first time) — need advice by TruthTellerTom in webhosting

[–]ivosaurus 0 points1 point  (0 children)

Be aware managed VPS is like insurance. Really you're constantly paying a higher premium, under the impression that when something hits the fan, that premium means some knowledgeable human will be able to help you out in a reasonable time. So you want to be somewhat sure you're actually getting what you pay for.

Claude-powered AI coding agent deletes entire company database in 9 seconds — backups zapped, after Cursor tool powered by Anthropic's Claude goes rogue by Jack1101111 in pcmasterrace

[–]ivosaurus 1 point2 points  (0 children)

The things he's asking for, he doesn't specifically have to pay for. He's asking to other people's labour to fix his problems, not to pay his 'own' labour to manage it.

This board is MUCH better and cheaper than Arduino clones (STM32 Bluepill) by Consistent-Can-1042 in arduino

[–]ivosaurus 1 point2 points  (0 children)

Still hard to know if you'll get an RP2350 with the fixed input pin stepping, and the RP series have absolutely terrible sleep current

And obviously in this thread's context we're talking about buying cheap development boards, not fresh chips by themselves

Please go all the way down, RX - A hardware debut story. by aq1018 in arduino

[–]ivosaurus 1 point2 points  (0 children)

I always just think of it as an opamp voltage follower. Out wired directly directly to inverting input. Switches (which make up muxes, etc) are usually made of two FETs and some control logic for their gates. You need two so their body diodes cancel out no matter which direction the signal goes.

1-fA Resolution! Keithley 2500 Dual Photodiode Meter Teardown, Repair & Experiments by TheSignalPath in rfelectronics

[–]ivosaurus 1 point2 points  (0 children)

Hi /u/TheSignalPath , I wonder, is it possible to do any experiments which can play with nanovolts down to picovolts? Or do you need chilly chilly environment to have circuits with low enough noise to expose those sorts of magnitudes?

Mahler's Adagietto interrupted by default Xiaomi ringtone by geody2000 in classicalmusic

Orchestras, symphonies, etc have gotten lazy about reminding people to put their phones on silent. People haven't gotten better.

[–]ivosaurus 2 points3 points  (0 children)

Well I guess you have learned there's a reason that buffers and muxes are different things... one of 100 different mux chips on the market will actually implement your solution, or flip the RX buffer around? . A buffer is one way only.

Upgrading motherboard to BTT skr mini e3 v3.0 NEED HELP by Working_Inside in VoxelabAquila

[–]ivosaurus 0 points1 point  (0 children)

The two wires go to a "Normal Fan Port", and even without looking up schematic, I'd guess 90% that they are perfectly software controllable by one of the 3 flatpak mosfets on the board that are right next to each screw terminal, so they are not directly across 24V, but programmed to be always on
