The drill — tool is handy and versatile, no wonder it enjoys great popularity among home craftsmen. The drill can do everything: drilling, sanding, polishing, sharpening and even to cut firewood. But the main thing — of course, drilling. Hang a mirror, ledge, bookshelf, strengthen, loose furniture, hang or repair the door (you can enumerate a very long time) — almost no work is complete without drilling.
The name of the athlete rakatomalala Igor Ponomarev, that is, “hearing” and “rocket scientists” and, hopefully, our readers. His technical model development are of genuine interest. For the very same designer search new is the way of athletic perfection, which is especially important for the future of aeronautical engineer (today Igor is a student of Moscow aviation Institute). I guess this is a good example for our young readers.
More precisely, one (50 or 65 watts), operating in three modes. Design advantages: constant availability, visual inspection of the three modes, etc. All provide automation. Power consumption in the idle — 15 watts (on L2), in the normal operating — 45 W (L2 and L3), and overheating — 50 W (L3). Changing modes 2 and 3 is made by the switch B1, in standby mode, by overlapping the luminous flux from L1 to K3 with the handle of the soldering iron.
Many of us love tinkering with their hands various things. But few dare to really costly, complex and lengthy projects. Present to your attention a development tank, a helicopter, a submarine and a roller coaster built by lone on pure enthusiasm. And you weak?
(The story of one of the invention). Red cat almost ate squarecat. She climbed to the skvorechnya and wanted a paw to climb inside. Well, we Petka noticed!
The period between the two world wars represents a considerable interest to historians of technology, and first equipment of aviation. The aircraft of this time, the construction of which has absorbed the existing scientific, technical and technological achievements, remained nevertheless the bearers of the greatest characteristics of the airplanes of the First world war.
