Instead of the usual steering wheel, I installed a column of the front manual drive of a two-stage chain transmission on the bicycle machine (Fig. 1). When moving, depending on the height of the cyclist, the angle of the column can be easily changed. The saddle is moved back. Both wheels are leading, have five-speed Read more…
It often happens that guides on how to build a boat yourself simply scare off beginners with such “mysterious” words as “epoxy resins,” “foam,” “fiberglass,” “bakelized” or “aircraft plywood,” etc. More experienced boaters are scared by something else: the difficulty of acquiring these materials. Meanwhile, a good boat can be built from simple materials available Read more…
The experimental winnowing machine-sorter is designed for selection work. The winnowing machine body is made of pine beams, to which the side plywood walls are attached. The beams are assembled into a tongue and groove in half a tree. The receiving bucket is equipped with a flap, the movement of which regulates the grain feed. Read more…
No matter how much we talk about the windsurfer being the smallest sailboat, you still can’t get on a trolleybus with it. To transport a sailboard, you need at least a car. Of course, it is possible to transport a boat about 3.5 m long on public transport, but… …it would be better if it Read more…
Electric drive? For a boat? So, doesn’t our industry produce enough gasoline outboard motors? Go to a sports store and choose any one – from the lightest, suitable even for a kayak, to the heavy and powerful Neptune. But we still need crystal clear water without an oil-and-gasoline rainbow on the surface, we need undeterred Read more…
It’s getting dark. The sun is slowly setting towards the horizon. Dusk is coming. It’s still early to go to bed, I want to read and play chess. For motorists, energy for lighting is provided by a rechargeable battery. But hikers can also use electric lighting with no less success – a pocket wind power Read more…
Have you ever wondered what to do with an old screwdriver that is lying around idle because of a dead battery? I had a similar situation – a friend gave me his old Bosch with the comment: “The batteries don’t hold at all, it’s just torture.” So what do you think? I decided to breathe Read more…
Maximum simplicity of design and minimal complexity of manufacturing – these are the principles that were used as the basis for the creation of the Gnome micromotorcycle (see photo). The frame is made from parts of a scooter and a frame from a road bike (see Fig. 1, 2 and general view). The connected horizontal Read more…
The magazine “Modelist-Constructor” (No. 6, 1983) published drawings of a miracle stove designed by I. Maslov. Wonderful stove! Especially for those who love to travel. We have introduced, so to speak, an oriental accent into the organization of country holidays: we have designed and now carry with us a folding barbecue, we call it a Read more…
Easter is just around the corner, which means it’s time to work miracles. And if you’re tired of regular paints, I’ll show you how to build a real robot artist that will paint on eggs! Meet Eggduino. This is a small but very smart machine that runs on Arduino and is controlled via Inkscape. With Read more…
