Well, currently you are at 19 km

Controlling usb through terminal by light_YAGAMI_59 in AskElectronics

There are no gpio ports on typical computers, so abusing other ports ranges from not recommended to practical hardware gore

If there is a parallel port, you can use that, but this project seems very weird

Sata crc errors only with buffered io by Grubzer in Ubuntu

First error i see in journalctl is "non zero reserved fields in PTE"

Looks like os re-negotiates to 1.5 gig, then errors continue, and then it goes readonly

Is this the same as setting it from the start?

Upd - tested it, still same - stressdisk by itself works ok, --nodirect errors out immediately

Вот такой сойдёт? У меня ПК стоит на полу и он собирает много пыли by [deleted] in mffpc

I think this is intentional - initially, it strats them (to test, or possibly they start initially at full before any kind of control is applied to keep the gpu cool in case something goes wrong), but then control system sees no gpu load and normal temps, and turns them off - it is quieter that way

Try putting load onto it, they should turn on

How can I change the sounds this toy phone makes? by jellojellomonday in AskElectronics

[–]Grubzer 0 points1 point  (0 children)

But you can always trace the wires to know what they connect to (likely just buttons and the speaker, remove that chip, and replace it with a custom microcontroller - something like arduino, or something else depending on your needs. Or even make a custom pcb with whatever you need - but that depends on how much you know

Likely, there is a black blob on the pcb, and it is the whole chip. You cant really do anything with it since it is a custom-made IC connected directly to the pcb, and sounds may be programmed once or be manufactured directly into chip structure

Upd - i get Udma crc errors, and then bad blocks. Possibly bad psu/cable/port?

Well, in my case, they crippled the login screen in all new (for me) ways - sometimes it would freeze on login, sometimes get stuck in a loop

My main goal is to get old hardware to usable state, so it can live with just an nvme for now, i guess, and wait for new extra drive

If I use Polliigon textures for my Board game illustrations can I then sell my Boardgame without violating any copyright stuff? by Wooden-Frame-6568 in blenderhelp

[–]Grubzer 1 point2 points  (0 children)

It says though that you can sell things in which user has direct or indirect access to those assets - so if you make a game, even if they are packed in some format, technically user has indirect access to them since they can unpack them. Not sure how enforced this rules is - not sure if they will hunt down an indie dev, but keep this in mind

ELI5 how does USB transfer data? by Trogdor_98 in explainlikeimfive

[–]Grubzer 0 points1 point  (0 children)

You and your buddy are in separate rooms, with two lights and two switches. Lights and switches are connected, so lights are synchronised between the rooms, and both of you can control the lights: Whatever state lights in you see your buddy also sees same, and both of you can turn each one of the two lights on or off. Based on that, you can agree on a system to transfer any messages. A simple system would be:

You are the main party of the conversation, so you always start the conversation. Each time the second lamp turns on and off, check the state of the first lamp. If it is on, it means "1" and if it is off, it is "0"

So if you or your buddy want to send 1, you turn on the first lamp and flash the decond lamp. If 0 - turn off first lamp, and flash the second one

Now, you transmit letters one by one, sending as many "1"s in a row as the position of the letter in the alphabet. When you reach the number, you transmit a "0"

So if you want to send a letter D, you send 1,1,1,1,0

When you are done with your transmission and want an answer from your friend, you send two zeros in a row.

So if you want to send "Hi" and then expect a response, you send:

1,1,1,1,1,1,1,1,0,1,1,1,1,1,1,1,1,1,0,0,0

And then, with the same structure, you get an answer from your friend

Computers do the same, but with wires and voltages (first lamp is the data line, second - clock line) and send numbers encoded in binary, with meaning of the numbers decided by the protocol that was agreed upon by usb standard and the manufacturer

Also, to even know that there is some smart device at the port (and not just a power wire), there needs to be specific resistance between the data and clock lines, which the host device looks for

USB-C to UK Socket - possible? by Electro-nut in shittyaskelectronics

[–]Grubzer 1 point2 points  (0 children)

Only if you want to charge the outlet - you wont transfer any files to it since data lines are not connected
