When dismantling microcircuits, the leads that have been bitten off from them and remain in the board are usually removed using a soldering iron and tweezers. In this case, due to overheating, there is a danger of the printed conductors peeling off from the board. The method I use allows for a low-power 15 W Read more…
For many years, I have been mounting my amateur radio homemade devices in universal cases made according to a single scheme. This is a frameless construction consisting of two U-shaped parts: a base and a cover. They are made from sheet steel of the required thickness (usually from 0.3 to 1 mm), which when connected Read more…
Our town is located on a large “edge” of the huge West Siberian forest. The most beautiful places. Nature simply beckons to go hiking. And in the warm season, there are no problems with this, as they say. It’s just that most of the year the weather is cold and there is snow. And when Read more…
I want to share with readers my small devices that provide additional convenience when organizing a campfire at a rest stop during a weekend hike or journey through one’s native land.

Vakulenko were published. His trimaran consisted of three folding hulls arranged in a triangle Read more…
The tourist amphibious boat “Amfa” was built by Vitaly Gennadievich Lebedev 35 years ago. Over many years of operation, it naturally underwent several modernizations, but the original design ideas embedded in it have not become obsolete. “Amfa” still pleases its creator and his family, demonstrating excellent qualities both on water and on land. In the Read more…
At the time of making this simple watercraft, which is even difficult to name: “either a junk, or a boat, or a boat, or a raft,” I had a “Kazanka” — a spacious, sturdy boat. However, it was intended for sailing with an outboard motor. But what kind of fishing, tell me, in a quiet Read more…
