They say you can’t save much on matches, and yet… A simple and practical electronic “match,” the description of which we offer to readers’ attention, will free you from the need to constantly monitor that matchboxes don’t remain empty. The “match” works as follows. The electrical energy accumulated by capacitor C1 (see the schematic diagram) Read more…
What lengths fishermen won’t go to for good luck. Once my friend — an avid angler — complained that often the catch turns out meager simply because there’s no way to cast a bottom fishing rod to the spot where, presumably, the fish should be: either bushes are in the way, or there’s not enough Read more…
It’s no secret that halogen lamps used in automobiles often fail. This happens as a result of a current surge that inevitably occurs every time they are switched on, when the filament coil is still in an unheated (cold) state. For example, a “halogen” fog lamp is designed to operate in normal mode with a Read more…
Numerous gatherings of amateur aircraft designers brought together hundreds of small aviation enthusiasts, and this clearly showed that interest in designing amateur aircraft is enormous. However, in many cases, an insoluble problem for ultralight aircraft enthusiasts is the engine problem — powerful, light, compact, and economical. I believe that if industry produced such engines, small Read more…
The experience of potato growers shows: Dutch technology for growing root crops is the most effective, with minimal labor costs. The rows are clean and even, and the harvest is excellent. The foundation of everything is properly organized planting and, naturally, good equipment. I offer readers a brief account of the technology itself, as well Read more…
To build a simple, unpretentious, and reliable car, I was, one might say, forced by circumstances. Back in the memorable times of general shortages, I bought a well-worn “Zaporozhets” that spent more time in repair than on the road, waiting for me to find the necessary spare parts. After several years of such torment, I Read more…
In a homestead-type house with a subsidiary farm and several auxiliary buildings, a wood-cutting machine, called a circular saw among craftsmen, is simply necessary for their maintenance and repair. I have such a machine too, also homemade, like most of my “homestead” equipment. I made it with the calculation that it could perform carpentry and Read more…
All-terrain vehicles on ultra-low pressure pneumatic tires are becoming increasingly comfortable. If a decade ago enthusiasts of all-terrain vehicles created mainly three-, four-, and six-wheeled vehicles devoid of even a hint of a cabin, today amateur designers send to the editorial office photographs of all-terrain vehicles they have built with comfortable and warm cabins designed Read more…
There’s no end to the chores on a farmstead. Some involve lifting, loading, or moving heavy objects. But when you only have two hands, such tasks can sometimes become an insurmountable problem. However, if the farm has a tractor, which is not uncommon today, heavy lifting can be “entrusted” to it by using the hydraulic Read more…
For residents of the Urals, Siberia, the North, and the Far East (that is, most of the country’s territory), the need for a vehicle like an all-terrain vehicle is simply a vital necessity. There are many reasons for this: good roads are few, the terrain is rugged, in winter almost half a year there is Read more…
