Hi, I'm Rauf Aliev.

Only I could throw my back out installing this engine. What a dangerous hobby I have

I’ve started to slowly make a 3D scanner in a more proper form than just a cardboard cutout on an axis. Connected a motor, measured on wood, made three levels of mounts for the phone, printed parts on a 3D printer. The scanning process takes about a minute. Another hour goes into converting to 3D.

I wonder why no one has yet created a service that allows searching for videos (movies?), where people speak with the same voice tone (perhaps, in the same language) as the uploaded voice? Something like tineye, but for audio. All movies are digitized, we just need to find a way to identify the characteristics that make us think the voices are similar, and index them accordingly.

One night – and the bike light mount is ready. Almost always, instead of 3D printing, you can buy a ready-made solution like this light for 25 bucks. But the thrill of “I thought up and made it myself” cannot be bought for any money 😉 P.S. As for replacing this broken light, I bought a new one several weeks ago. So this will be the second one, too good to go to waste

The first swallow. Or I don’t even know, darn it. An attempt, partially successful, to create on a 3D printer an object that contours around part of the front panel of the car. Quite a complicated engineering task. I scanned the cast with a homemade scanner, but then the digital copy must be resized to the dimensions of the cast. It’s not trivial because there are no clear reference points. Well, here I seem to have hit the mark accurately, having to enlarge the digital copy by 8.3 times. Next, it’s important to consider that a millimeter error will lead to poor shrinkage. I slightly pushed through here, but pliers and a file….

I needed to scan a complex-shaped piece of a car’s interior for a home project. I’m currently making a papier-mâché mold, and while it dries, I decided yesterday to assemble a 3d scanner. It took an hour to create the scanner. It consists of a rotating platform (bearing) on which the camera (phone) captures the object from 360 degrees. This is a prototype; I’ll make a proper one later. For the test object, I chose a wooden mount from an easel.

My ancient 3D scanner gave me 500 photos from all sides, each with a resolution of 2160×2440. The processing was done on COLMAP (feature extractor, exhaustive matcher, mapper) and then on openMVS (reconstruction, triangulation, localization, refining, texture application). It took about 10 hours. I probably went overboard with the number of photos – for a 360-degree view, half of 500 would have been enough. There are artifacts due to the shooting being only in one plane. In the second version of the scanner, I will make the phone movable along a curved guide, and the object will be shot from different planes.

The scanner itself mainly consists of:

– a bearing

– a box

– packaging from a laptop

– packaging from a smartwatch

– kitchenware

– a pencil sharpener as a counterweight to the phone, so it doesn’t tilt the box due to the weight of the phone

– an iPhone 12 Pro Max. This is, actually, the most expensive component

This is what I ended up with. I’m also including a photo of the model itself for comparison. There’s also a video here where I rotate it.

In the meantime, it already has 115 million views

The “Skilled Hands” Club purchased an entry-level 3D printer, the XYZ Da Vinci 1.0. And I’m having trouble with the Silk PLA; the first layer isn’t adhering well – it starts curling up, and the model shifts right from the beginning, causing everything to go awry. I ordered some glue. But it will only arrive in two days. What to do in the meantime, without glue? I went looking for sugar. There’s absolutely no sugar at home. Found honey! Well, am I not a solution architect? I added a bit of water, microwaved it, applied a thin layer, wiped off the excess with a napkin – and it works! Just great, why did I even buy special glue?

I am printing a part for a smart trash can. It has a sensor that opens the lid when a hand approaches, but it also reacts to people walking by. I unscrewed the sensor, relocated it to a convenient spot, and now I am printing a cover/mount for the sensor board.

Instead of diet pills, they should release scales for weight loss and mirrors for weight loss, and also a special mode for smart speakers to accidentally throw in jabs on the subject.

In the US, the first digit of the ZIP code indicates how far the location is from the East Coast. Hence, postal codes in New York start with 1, while along the entire West Coast (California, Oregon, Washington) they begin with 9.

In Russia, the first digit of the postal code is formed as if tracing the borders in a counterclockwise direction starting from the north. Nearly all the territory is covered by postal codes starting with 6. Codes starting with five are designated for international mail reception points abroad. I failed to find anything about them except for code names – Tskhinvali, South Ossetia (postal code 500200), London (500380), Newark, USA (500380), Virolahti, Finland (500580), Basildon, England (500680), Singapore (500780), Altanbulag (500880), Folcroft (500980).

Tskhinvali: “…Following the signing of the Memorandum, ‘Post of Russia’ used its own funds to restore the main post office destroyed in August 2008 in the South Ossetian capital of Tskhinvali, equipping it with all necessary equipment, furniture, computers. The same services that are available in any modernized Russian post office are accessible at this branch,” noted Kotov.”

Altanbulag: “…In September 2019, a Strategic Cooperation Agreement was signed between FSUE ‘Post of Russia’ and JSC ‘Mongol Post’.”

Apparently, all these “international mail reception points abroad” are just virtual. I was unable to find anything physical.

While researching, I found that the Russian post was active in China from 1870 to 1920, in Crete from May 13 to July 29, 1899, and even in the Ottoman Empire.
