Circular saw— a very useful thing in any household. On the usefulness of it, perhaps, is in second place after the drill. About design systems: easy-peasy. The basis of it —motor type TAO-AND from the washing machine. The electric motor is not necessary to purchase especially for the time it can be removed from the available machines (it is quite easy to dismantle), simultaneously lubricated bearings. Notice that the margin of safety and durability, this unit is very significant, so it is a temporary use of the saw will not lead to a noticeable reduction in resource most of the washing machine.
Off-road amphibious all-terrain vehicle tires low pressure, built studente and employees of technology and economic faculty of the Vyatka state pedagogical University, in operation for more than ten years. During this time, confirmed the unique capabilities of the machine. The Rover moves steadily along any road, through thick dirty, snowy or swampy terrain of the area covered by tussocks and shrubs, overcomes water obstacles. Its own mass of about 250 kg, can carry up to 500 kg of cargo on water and land.
We offer homemade compressor is designed for use in the home. With its help you can quickly and efficiently carry out paint work or the pump wheel of the car. The compressor consists of a motor and driven in a movement of the nozzle of the pump.The nozzle is mounted on the mounting plate, is mounted on three studs. Pump — diaphragm type. It consists of an aluminum head, to which the studs are attached to the socket of the intake and exhaust valves, and diaphragm of rubberized fabric sandwiched between the head and the steel ring. With the pressure plate diaphragm connected with the piston and the connecting rod.
Among the variety of flashing Christmas lights increasingly popular get the “ultra simple”, consisting… only of the LEDs. Instead of the usual piles of circuit design (with electronic keys, which are intermittently open-closed low-frequency RC, RL or LC oscillators) here compact semiconductor light emitter. However, the LEDs acting as a kind of microswitches, not simple (Fig. 1A—1 b). The name of this class of optoelectronic devices, developed at the junction of integrated microelectronics and optics — Blinking LED lamps (flashing LEDs, or MSV).
Cockroaches: they were not done by people to get rid of these black and red rogues, but the Extermination of such resilient insect still is a problem. Especially for the residents of densely populated high-rise buildings, dormitories and dilapidated “hruschob”. To a very promising means of control of cockroaches is possible, in my opinion, to include electroshock devices, even of the simplest type. I, in particular, has been a “electrovoice” to exterminate an entire Armada Ryuusei insects at the entrance directed to the former owner of the apartment.
