Many plants, like tomatoes, during its growth and fruiting require a lot of moisture, so they often have to be watered, especially in hot season. The proposed machine will help you save valuable time and eliminate the need to be constantly “tethered” to their Pets. Just turn on the power and set the clock correct time of watering. The device is simple to manufacture, and at the same time it is reliable in operation.
When using electrical appliances (e.g. electric light), there is an inconvenience: you want to sleep but have to get up to go to the outlet and remove it from the fork. The proposed electronic device allows you to control (turn in work on or off) of various household appliances at a distance of just spoken sounds. Suffice it to say a certain word and please: earned (or stopped) the radio or television; lit (or extinguished) electric lamp or Christmas tree garland.
In my opinion, the most effective seem to be those developments that do not need to “up from zero”: we will focus on improving ready-made industrial electronic devices on their own. The result is a very modern functional design, one of which I bring to your attention. This is an additional node to industrial flash SEF-1 produced once the millions of “copies”.
ULF bass reflex on one first transistor. Numerous calculations and experiments to create powerful high-quality low-frequency amplifier has led me to believe that the most promising way to the design is to use a phase inverter on one first transistor. It is curious that such amplifiers could be forty years ago, but this has not happened due to a number of reasons.
For several years Samsung cell phones are available with the new universal (multi-function) mini-connector. Compact and flat (see photo), it provides charging from the adapter, connecting headphones, connecting to USB port of personal computer (“data cable”) to operate the phone as a modem and many other features.
One of the inconveniences in the design of many cars is that the interior light goes out immediately when closing the doors. There are, however, a special device to delay the power light on 5-15 that the driver had time to explore the dashboard controls and to insert the ignition key. But these developments are usually complex and expensive. And reliability often leaves much to be desired.
The so-called “mouse” is an integral part of a modern computer. With the advent of new, old, still working, but outdated morally, as a rule, thrown away or gathering dust idle in the pantry. However, they can be used practically without changing the electronics. Make it a snap.
On occasion purchased a portable led flashlight in China with the battery inside. The flashlight has the ability to switch between a cluster of eight super-bright LEDs and a krypton bulb for a voltage of 5.4 V. Inside there is also a charger for the battery. In addition, the lamp is combined with a lamp – a fluorescent light with a power of 6W, powered by using a special voltage Converter 150 – 6th Century
