Familiar to many hams, the situation: once the scheme is built, configured, but… to Squeeze it into some kind of “soap” not want to, but new to “diamond” the right frame there is neither time, nor forces. Had to find a way out of similar situations and me while in one of the publications, “Model construction” did not find a clue. It turns out that enterprising and slopestyle Siberians, which wrote the log, began the production of fine gift boxes of foil materials commonly used in the manufacture of printed circuit boards. Moreover, the simplest technology: the workpiece-scan in the field of future folds (from the base-insulator), they made cuts, and after giving it a box shape was probabaly foil joints.

A DAY ON THE WATER SHAKES THE NIGHT HOUSE GUARDS
I designed the machine addressed to the farmers and owners of summer houses with auxiliary water supply system, key units of which are a water source (river, lake, well or borehole), water tank electric pump Yes. From analogues this development is characterized in that in addition to performing its main function — control the electric pump makes it quite successfully solve tasks of protection of objects. This unusual flexibility is achieved not by complexity of an electrical circuit device, and by quick-change sensors, which are not only submersible multi-level electrodes and photoresists or thin, working on the rupture of the wire.

FIREPLACE FOR BEES
Research scientists and experience of beekeepers show that with a good supply of benign feed and caring the contents of a winged honey bee plants can stand the winter even when severe frosts. After all trouble for weakened bee colonies in the cold season is not so much the reduced temperature, how much humidity, when the frames and the inner surface of hives moldy, and the increase of the thermal conductivity of moist air surrounding a ball of bees, and damp walls threatens to increase in heat loss with all the ensuing grave consequences.
