The design and operating principle of the device are as follows (Fig. 1, Read more…
Boys seem to have a natural pull toward technology — probably something embedded in their genes. Yet, there’s a fairly long period in their lives (that so-called “transition age”) when they consider playing with toy cars too childish, but driving a real car is still not an option — and often, not even available to Read more…
“I read in Modelist-Konstruktor about the continuation of the “Small Mechanization” competition and decided to take part. I offer a simple and compact micro-mill. Its dimensions can be judged from the photo: the entire construction fits in the palm of my hand. It’s a universal device — designed for producing both coarse and fine corn Read more…
For those living near water, a motorboat is no less important than a motorcycle or a car: people use it to commute to work, visit neighboring villages, or go shopping in the district center. “Modelist-Konstruktor” has repeatedly published descriptions of various motorboats. However, judging by the editorial mail, readers are still interested in watercraft designs. Read more…
Dear “Modelist-Konstruktor”! In issue No. 9 for 2004 of your magazine, a material was published about a compressor I made based on a motor-compressor from an old refrigerator.

But instead of store-bought gear, you’re holding a speargun built with your own hands. That’s how our project began. We set out to create a real underwater speargun from scratch, using natural materials, minimal tools, Read more…
Many outdoor enthusiasts prefer cycling trips to other forms of short travel, such as hiking or driving. Walking allows you to fully enjoy the beauty of nature and take in the surroundings at your own pace, but unfortunately, only in the immediate area. Driving, on the other hand, means you interact more with the road Read more…
Sometimes, genius hides in a garage. That’s exactly what happened with Andrea Marazzi — a mechanic from the Italian town of Bagnolo Cremasco. Imagine this: an ordinary 1993 Fiat Panda suddenly becomes an internet sensation because… it was made hilariously narrow. Not just narrow — just 50 centimeters wide! It’s no joke — it’s both Read more…

One such tool is the jigsaw, indispensable when working with plywood, thin plastic, and similar materials. There are several options for replacing a hand jigsaw with a mechanical one: an attachment for the Read more…
The young naturalists of Cherkasy Secondary School No. 3 surely still remember the rabbit Belka, who gave birth to 96 kits in a year — three to five times more than usual. Belka’s offspring yielded nearly half a ton of meat, and the pelts were enough to make five children’s fur coats. We offer three Read more…
