A few days after Google demonstrated the capabilities of the autopilot Toyota Prius, the aerospace company Terrafugia announced the successful test of a flying car. The prototype of the aeroplane, permission for construction was received in July last year, took off and successfully landed on March 23 in Plattsburgh, new York. Terrafugia Transition – the two-seater with folding wings that can drive on highways and flying on unleaded gasoline.
THE WATER IS HEATED THE SMOKE
Having a stove ( coal or wood), it is possible to provide hot water sink in the kitchen and even the shower using the heater device, allowing the use of the heat of the hot gases that are removed through the chimney plate.
Design and operation of the device is the following (Fig.1,2). Tube heater built into the chimney as close as possible to the stove. The hot water from it flows through pipes in a metal cylinder (e.g. from fire extinguisher) that has a coil and is connected to the water network and tap over the sink. The water filling the tank, is heated by the boiling water coming into the heater coil.
Tricopter with a video camera
I spent all summer with her son, a soldering iron and Arduino IDE, not in the field with a copter, so now my free translation of article Swede David Windscale (David Windestål, I hope correctly wrote) about the construction of tricoptera — stone with three engines and a rotary mechanism to compensate for the rotation and control the rotation. (please do not walk unnecessarily on the site of the original, as he often falls Habra and under the cut a lot of images).
TRUCK-SCARCE
For a long time I enjoyed long ago acquired by manual uniaxial shopping cart (unfortunately, information about the manufacturer not preserved). But remember, in the passport on the cart was given data: load capacity — 25 kg weight — 6.5 kg. the Trolley is made, that is, the conscience, the design is reliable, very simple moves from transport to working position, and it happens that I’m on it loads up to 50 kg, that is twice the nameplate figure. Now it is clear that the manufacturer of the truck was safe and resulted in low capacity, as the possibility of a much larger truck. The developer could specify the actual value of the load capacity, but it was necessary to test truck durability.
COLLECTIBLE COINS
There are three basic types of coins. Coins in circulation that we use the weight of the coins for investment and collection coins, high quality gold and silver coins issued in honor of the momentous event. The mint produces collector coins from silver bullion, as well as waste from the production of other silver coins. Silver gets into foundry furnace with a temperature of 1150 degrees Celsius. Then the molten silver is cast in a continuous block of thickness 4 cm and width 12 cm.
PEANUT BUTTER
We know peanut butter was invented in 1890 by the American doctor. He used it as a protein substitute for patients who were unable to chew meat.
For the production of peanut oil is best like peanut varieties Runner. Its grains are of equal size, and roasts more evenly than with grains of different sizes. The plant for the production of peanut butter they put already cleaned. For the manufacture of 500 gram cans required 560 grams, or about 1100 nuts.
VELOVIC WITH POCKETS
Two-wheeled transport — an indispensable tool: the products whether to go to a distant shop or a neighbouring market, potatoes from the garden to bring — but few if any economic goods in need of transportation. However, a standard rear bike helps not always.
I propose to produce for these purposes a special velovic — spacious basket on the trunk with “hanging” on the sides of the rear wheel pockets. The packs may be rigid (e.g., plywood) or soft, like a backpack.
“WATER BUG” – THE FISHERMAN’S BOAT
Some fishing without a boat? Especially on large bodies of water. Want to make an original, near-silent boat? To business, then.
Look at the picture. Interesting boat, built on the basis of inner tubes and beach chairs, offers the readers of the American magazine “Popular mechanics”. Equipped with oars or a light motor, it is able to quietly move around the pond, allowing silent access to your favorite places. Sitting in a boat, you can just drift or drift along the river, choosing your favorite area.
THE YAK-1B
THE YAK-1B. Scale model 1:33.
Normandie-Niemen – name fighter aviation regiment “Battling France” – acted on the Soviet-German front in 1943-45. the Pilots of the regiment destroyed about 280 and damaged 80 German aircraft. In November 1944 for the differences in the battles for the liberation of Lithuania and in crossing the river Niemen regiment was given the honorary name”Neman”.
“SNOWMOBILE” IN FIVE MINUTES
You can understand the burning desire of the baby who saw for the first time the competition modelers, asking parents to buy or make him a miniature technique, not postponing it for later when he grows up and goes to a club.
Propose a simple dynamic model will be able to help parents in a similar situation, because it forces to make yourself out of scrap materials, very quickly and most importantly with your child. In such cases the boys could evolve into a love for a fascinating and accessible in this age, the technical creativity — modeling.
