Smartphones look similar on the outside, but the real changes are inside. iPhone 17 teardown — a journey into Apple’s engineering kitchen. Engineers worked hard: fixed old problems, made bold moves.

In recent years, with the growth of personal household farms, demand has increased for the Muravey cargo scooter; it is especially needed by rural residents. In 1983 alone, 12,000 of these machines will be sold. For the huge number of our villages, this is, of course, not much. By contrast, almost half a million motorcycles Read more…
The advantages of an outboard waterjet were already discussed in the article «Water instead of a propeller». Now we will tell you about its design. The waterjet installation we developed is intended for a wide range of enthusiasts. The waterjet is designed for a two-cylinder SM-557L engine, but can work with any other engine that Read more…
When designing this car roof rack, the aim was to create a device that, in addition to everyday use, would suit the active outdoor enthusiast—allowing two sets of sailboards to be carried in summer and (with minor changes) 5–6 pairs of skis in winter. Given the considerable weight of two sets of sailboards (about 54 Read more…
