SECOND COUNTS… “MOUSE”

COUNTING SECONDS... Currently available a variety of models of wall elektromekhanicheski quartz watches with stepper motor. They are, as a rule, uses unpackaged integrated circuit — the oscillator/divider with an external quartz resonator coated with black compound.

DRILL PIPE…

DRILL PIPE...I want to share with the readers one very simple method of drilling holes in the glass, which I was taught many years ago Professor N. A. Artemyev.

The edge of the hole can be as close to the edge of the glass; the method also allows to cut out rings and circles of different diameter.

ELECTROCITY

ELECTROCITYSomehow I read in your magazine the article “rainbow on aluminum” and remembered a very convenient way of drawing figures and inscriptions on metal. Brush for these works is a glass tube filled with electrolyte which has the ability to seep through the hair insert one end of the tube.

ANTENNA... RAPID MANUFACTURINGOnce, while on vacation with an overnight stay in a tent on a wooded Bank of the river, found an annoyance: a portable TV operating off the car battery, bad was shown on the set of the antenna due to the weakness of the incoming signal. Then began experiments with aerial: spinning her this way and that, but to no avail. Then began to try to connect to the antenna and instead found in the boot of the wire.

“…TO UNWIND THE YARN,”

Fingering binder “Modeller-designer”, I found in No. 11 for the year 1978 note “Fixture austere”. It was about the simplest device which can be used to facilitate the rewinding of the yarn from the skein into a ball.
