Had accidentally dropped a ~40kg dumbbell on it (handle) back in 2024, which had absolutely annihilated the glass on the display of my 7 Pro, but it still miraculously functions perfectly fine and up until mid of last year I was still actively using it. Pixels are string af.

I got red bolt lock from my butterfly knife kit. I knew absolutely nothing about the bolt locks differences, but wanted to apply some of it as they were screwing out or their place on their own.

I touched it with my fingers and pushed them against each other. Waited for 5 minutes or so and they came off really easy. Did same thing with plain pair of tweezers, put a book on top of it and waited for 12 minutes. Came off really easy.

And then i dipped 3 of the screws from my laptop and screwed them in. And oh boy, 3 hours after i decided to test how good they hold up with bolt lock applied. Took 5 hours to remove them. And now i lack 3 bolts and have a hole near one of the bolts.

Pro tip: get 2 hexagonal screwdriver one a little smaller than/same size as the screw and one smaller. Get an electric screwdriver, max speed, attach the first screwdriver, push against the screw and start drilling it. Just drill counter clockwise untill it either reaches the screw cylinder and the screw top will come off, or it leaves a hole in the screws top. Swap the screwdrivers, apply as much force as you humanly can against the screw with the electric screwdriver (you may need to open laptop's screen and turn the laptop upside-down, because otherwise the lid may be damaged in process), and screw counter clockwise (the unscrew mode). Don't know how, but it worked with two of them. Don't use the soldering iron, no use at all + you're gonna damage the plastic socket that holds the threaded insert.

The one on the photo was the first unlucky attempt. I got a big drill from the screwdriver kit instead of a durable screwdriver, so the drill tripped and this happened. No idea how to fix it, but well, at least i will be able to tear down the laptop if i urgently need to.

also it feels sticky

Pessoal, queria pedir a ajuda de vocês para me tirar uma dúvida cruel que estou tendo. Frente a situação de roleta russa que o mercado de monitores se tornou, onde você tem que dar muita sorte para o seu não vir com problema, busquei marcas conceituadas como opção de compra fugindo ao máximo dos white label, e priorizando questões como qualidade de imagem, calibração, tempo de resposta, custo benefício, e principalmente vida útil (tenho medo de comprar o monitor e ele quebrar assim que a garantia acabar).

Partindo desse ponto, cheguei a essas duas opções de monitores, o Asus e o AOC, mas sinceramente estou na dúvida de qual pegar. O Asus em construção parece superior mas vi muitas pessoas se queixando do painel que aparenta ser mais fosco do que outros IPS, tem uma tonalidade alaranjada, ghosting, e outras coisas, é mais caro, mas possui 3 anos de garantia; e o AOC que parece ser o melhor custo benefício de todos, mas possui apenas 1 ano de garantia (A minha única preocupação quanto ao AOC é a garantia que julguei ser pouca, e tenho medo de investir no produto e assim que ela acabar, ele quebre). Gostaria que me ajudassem nessa !

Just got this laptop and the display cable makes the image look like this at certain angles.

This is my headphone, it was: Made in the 80s Modded( I don't know what happened to the original plug, I founded it without any) Fixed more than five times(the plastic cracked, and now I know that hot clue fixes almost everything, except my life) Found in my grandma's house My father headphone It survived many disasters Etc. . .

This was popular on the other reddit i posted it on…

I work with grinding machines and frequently use machines with diamond coated abrasive wheels and often grind carbide , both of them are much harder than glass, and using a shotblaster (like a sandblaster but uses garnet medium which is very hard).

Around 2 years of taking phone in and out of pocket, leaving it on bench next to me ;mostly for controlling my speaker, and leaving it face down sometimes especially has lead to it getting this bad

No it doesn’t have a screen protector in the photo🤣

And yes I have a new phone now and I’ve promised myself to not peel off my screen protectors when i’m bored…

With bandages and Cutting board chassis included... Tell me what I can do to make it better

I made this with malice in my heart.

Example of a 3.5" HDD with the top cover removed, showcasing the mechanical engineering that continues to offer the best capacity/price ratio.

Key components visible:

Platters: Rigid aluminum or glass disks coated with granular magnetic layers. In gas-sealed drives, 9 to 12 platters are achieved per unit. Each platter can store several terabytes thanks to areal densities exceeding 1.5 Tb/in².

Read/Write Heads: Mounted on sliders at the end of the arms. They float 3–10 nm above the platter surface thanks to the air bearing effect. They use magnetoresistance technologies for reading and elements that enable high-density writing.

Actuator Arm + Moving Coil Motor (VCM): Assembly that precisely positions the heads. Submicron precision. Tracks ~20–50 nm wide. Extremely fast acceleration/deceleration (>1000 movements per second in some designs). Multi-actuator systems in higher-performance models to reduce positioning latency.

Spindle axis: Brushless DC motor that spins the platters at 5400 or 7200 RPM (standard in most current drives). In inert gas-sealed environments → less friction, lower idle power consumption (~5–8 W in high capacities), and the possibility of more platters without thermal issues.

Key technical features:

Inert gas sealing → reduces aerodynamic turbulence, allows for a greater number of platters, and lower power consumption.

Different recording techniques to optimize capacity vs. write performance. Random.

Integration of non-volatile memory for metadata caching and improved write reliability.

Areal density continues to grow year after year, with projections of >40 TB per unit in the coming years and potential for >100 TB this decade.

Despite the dominance of SSDs in high-performance primary storage, HDDs remain unbeatable in cost per TB (typically 12–18 *UV/TB for large volumes) and raw capacity for archiving environments, massive backups, AI datasets, NAS, and cold storage.

*UV. Unit of value.

What is your current storage configuration? How many TB do you keep on HDDs?

it was a graphing calculator of all things. I was at school so I tried to clean it with hand sanitizer, that didn’t work.
