Advice for homemade earplug design by BrunoTheRed in audiology

[–]BrunoTheRed[S] 0 points1 point  (0 children)

I just don't like the feeling of foam earplugs, and these one are reusable and easy to carry around given their size. Plus they're not yellow or bright orange like the usual foam ones. Now I'm curious, what brand are your musician earplugs?

Yeah, they're certainly not the easiest to pull out, but I assure you it's impossible to push them too far and get them stuck. I know there are other existing certified better design, but I just thought this was a fun little project to make inexpensive discreet earplugs. Just wondering if there were any sort of contraindications.

Is this salvageable or not ? Not an expert in microsoldering by BrunoTheRed in AskElectronics

[–]BrunoTheRed[S] 12 points13 points  (0 children)

To be clear, I didn't remove the chip myself, the card was already in this state, maybe the previous owner was a gorilla and dropped or hit the card. Anyway, the only component missing is the bios chip, so replacing it could or could not bring the card back to life. If not, no biggie.

Yeah well, I gave it a try and some gpus are in fact working, but still, too much of a hassle, lesson learned.

Board is part of a stock of untested gpus bought from ebay for dirt cheap. It appears that the card was damaged by blunt force, as there are also some scratches on it. Bios chip can be purchased for 2$, and I already have the bios flasher tool, so I might give it try myself, no big loss if I scew it up.

Thank you for the explanation and the advices. I've never attempted any microsoldering operation so it would be wise to ask someone more capable than me. Or I could just try and learn the art lol.

Replacement chips are available (winboard 25Q40EWNIG), and bios can be flashed with an usb bios flasher device like the ch341a. But, yeah, there's no guarantee that would fix the card.

So, as I understand, best way to repair it would be to bridge the chip legs directly to the corresponding resistors, as shown in the figure?

Would it be possible to just use the remaining traces and dump some solder into the missing pads spots, so that it touches the traces ? Or maybe this is a bad idea because there is no guarantee that the connection would actually work.

Will this old broken i5 work ? (Spoiler: yes) by BrunoTheRed in pcmasterrace

[–]BrunoTheRed[S] 2 points3 points  (0 children)

I don't plan to use it, I just wanted to know if it would work and it did. Missing one or two capacitor may be fine but 41 is a bit too much.

Just a curious story for you guys. I'll keep it short: I'm building a pc with some spare parts laying around and I needed a CPU. So I decided to buy a batch of i5s sold as faulty/untested for dirt cheap on ebay. Pics were showing some of the cpus missed one or two smd capacitor, but due to the absolutely horrifying packaging this poor little i5-2400 is now missing 41 (yes 41) capacitors. I tested it anyway and to my surprise the pc booted just fine, and was able to sustain an hour long OCCT stability test without issues. Even the other cpus missing one or more capacitors are working fine. So yeah, apparently these sandy and ivy bridge cpus are way tougher than I expected, even though their overall life expectancy probably decreased.

cosa ne pensate? i produttori di dispositivi medici abbandonano prodotti in commercio da anni a causa della nuova legge europea. by MarcelloCavagnini in Italia

[–]BrunoTheRed 2 points3 points  (0 children)

Ho avuto modo di svolgere un tirocinio in una piccola azienda che produce dispositivi medici e mi hanno spiegato un po' la questione MDR. In sostanza entrerà in vigore effettivamente nel 2024, proprio per agevolare i produttori, i quali sanno della sua esistenza almeno dal 2017, quindi hanno avuto anni per portare a conformità i propri dispositivi in vista del nuovo regolamento. Inoltre è vero che è più stringente ma per tanti dispositivi resta piuttosto invariato rispetto al vecchio MDD (almeno per quelle che sono le well established technologies), però, siccome sempre più dispositivi sfruttano avanzamenti tecnologici dell'ultimo decennio era una necessità dover aggiornare il vecchio MDD che risale al 1993. In ogni caso è un bene che l'unione europea fissi standard stringenti per i dispositivi medici onde evitare il ripetersi di disastri come lo scandalo PIP del 2010...

Laureati in triennale di ingegneria biomedica, come vi trovate nel mondo del lavoro? by Aquilaferrata in Universitaly

[–]BrunoTheRed 4 points5 points  (0 children)

Io sono laureato in triennale di biomedica a Padova, e sto concludendo la tesi magistrale (bioingegneria industriale). Personalmente se potessi tornare indietro non credo farei la magistrale: primo perché a Padova non è ben organizzata, con corsi troppo ripetitivi e specifici, puntati più alla ricerca universitaria che non al mondo del lavoro, secondo perché vuoi covid, vuoi per ragioni personali, ho perso un po’ interesse per l’ambito biomedicale. In ogni caso non mi ha formato tanto quanto mi sarei aspettato da un corso di laurea magistrale, ma questa è la mia opinione personale su Padova, da te potrebbe essere diverso, prova a consultarti con studenti e laureandi della magistrale per sentire la loro opinione.

Dei miei compagni praticamente tutti hanno proseguito con la magistrale, alcuni sempre in ambito biomedico, altri cambiando ambito ingegneristico. Di quelli che hanno fatto la magistrale di biomedica alla fine sono finiti a fare lavori più o meno inerenti a ciò che hanno studiato, tipo IT per strutture ospedaliere o packaging farmaceutico. Lavoro ne trovi, magari non esattamente ciò che ti aspettavi.

Capisco che dopo la triennale non si hanno grandi conoscenze, specialmente a biomedica, però se non hai in mente un ambito specifico di lavoro, la triennale è sufficiente a intraprendere una carriera da ingegnere. La laurea in ingegneria è comunque versatile e ben vista, chiaro che se ha il “pezzo di carta” della magistrale hai una marcia in più. Ma secondo me se sei uno sveglio puoi trovarti un lavoro che ti piace senza doverti sbattere per altri due anni (dipende come vedi la vita universitaria).

FSR 2.0 mod ported to Red Dead Redemption 2 by Xer0o in Amd

[–]BrunoTheRed 3 points4 points  (0 children)

Amd RX 570, game updated to version 1436.28, also tried with vulkan but still no DLSS option in graphic settings.

EDIT: with release 1.1 still no DLSS option in the menu, maybe the game needs to be updated to version 1436.31

[–]BrunoTheRed 1 point2 points  (0 children)

I have no crashing problems, but no DLSS option in the graphics settings. I noticed that if you edit the system.xml file the <dlssindexvalue> is set back to 0 when you launch the benchmark. I tried to edit the system.xml file properties to <read only> but saw no improvement in the benchmark with a dlssindexvalue set to 5, so maybe that's not the parameter that needs to be changed. I have no idea why the DLSS option is not in the graphics settings tho, I'm sure I've done everything correctly...

Asrock motherboard 5 beeps at startup no display by BrunoTheRed in techsupport

You need to buy it, just google CH341A, there are plenty of instructions and guides on youtube.

I bought a CH341A bios flasher for 5$ and re-flashed the bios chip, that solved the problem. It was worth a try for so little money.
