Or night duty (with reduced brightness) lighting, allowing at the same time significantly increase the lamp life, can be implemented in different ways. Among the simple and reliable method using a quenching capacitor in power supply circuit (Fig. 1). The capacitance C1 is calculated as reactance to obtain the desired lamp voltage ЕL1. Resistor R1 is necessary for capacitor discharge after disconnecting the circuitry from the network. Its value is in the range of 100-500 ohms.
NOT GROVER, AND DROP
The threaded fasteners connecting the vibrating parts, require an additional safety net to eliminate the loosening of it.

The author and Creator of the Rover, about which speech will go, — Boris Ryzhov — a longtime friend of the readers of our magazine. Photographs of the manufactured machines (crawler and six-wheeled all-terrain vehicles) were published in the journal in 1990 (No. 7). But the desire to create and to make a more perfect vehicle all-terrain since it gets cold. Professional aircraft mechanic and restless Amateur designer, after retirement, continued to build all-terrain vehicles. Why? Yes, until (and, apparently, for a long time) to get to most places in the depths of Siberia, where he lives, Boris Nikolaevich, it is possible only on such machines.
Narrow Cabinet-column in the hallway or bedroom very convenient for placing small items, but it requires additional space to allocate that in a small room is difficult.
