Buying a player up to accommodate for his food during his frequent touring on-Board generator. As the adapter decided to use a homemade solid state rectifier. The implementation of the ideas started by selecting a circuit diagram of the valve half-wave diode with a smoothing capacitor. Soon he was convinced regular Wellenreiter power 3-5,4 W and an output voltage of 6-7 V and the modified on-Board power grid using a rectifier for key any diode average power and capacitor µf 500-2200 quite cope with the new task. In the end, the player was to receive a 3-volt power supply when the Bicycle is moving at a speed exceeding 10 km/h with the included headlight and not less than 8 km/h is de-energized.

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).
Hoping to equip the apartment “talking” for hours, tried to collect an acceptable design using standard domestic circuits. But once faced with the complexities of the “firmware” electronic memory, decided as the basis for its hours to accommodate wrist alarm TALKING WATCH — cheap consumer goods from China. The result was an information system capable of interesting, in my opinion, and many readers of the journal “modelist-Konstruktor”.
It’s hard to imagine New year without festive lights and a Christmas tree with a mysterious flickering lights. However elektrogirlyandy industrial manufacturing not everyone is like: get bored of the monotonous flashing, and is harmful, they say it’s for health. I propose to replace these “flashers” an improvised device, lights which Shine like candles — with smooth change of brightness. Among its advantages are the simplicity of an electric circuit, which will be able to collect anyone, and the lack of scarce or expensive electronic components.
Voltage instability in the regional power lines, unfortunately, are not so rare. Especially during strong winds, when the wires of overhead lines of 0.4 can overlap. Because of the suffering of electro-, radio – and TV equipment, included in the housing network, where the voltage can suddenly become equal, say, 100, or Vice versa, 350 V. However, for my appliances I have five years did not worry, as the anomalous voltage in the network it protects a homemade relay system.
