Replacement flyback transformer in TV monitor МС6105 with CRT 31ЛК is, of course, not a major overhaul. Moreover, if the old monitor staff “strojnik” cope with the work, and to change this (very expensive, cranky and hygroscopic) node to the new is hardly appropriate.NEEDLE VS ICE
Using a wheelchair with a stick, faced with the problem of movement in ice. After several trials, it was decided to streamline the stick. In its bottom I drilled a series of blind holes with a pitch of about 5 mm. In need of them put an l-shaped rod, the lower end of which extends Read more…
One way to reduce interference in digital circuits, as is well known, is to install the ceramic capacitors in parallel with the power rails. The closer to the contacts of the chip capacitor is, the more effective his work is.
For the computer control various devices and objects I propose to use the method of pulse width modulation (PWM) is equally successful when working with different PCs: Intel-80286 to Pentium latest modifications. Perhaps, the only condition — the presence of a free com port. The relationship with him is up to 200 m can even be done through conventional telephone wires, no protection against the electromagnetic effects of the environment. In the transition to the more sophisticated, shielded lines of the “range” computer control with PWM increases.
To reduce the ripple in the filter of the rectifier sometimes try to put the capacitor as much as possible capacity. However, this is not always safe for the semiconductor valves.

In the presentation intentionally does not address questions related to installing OS and the principles of the model of relations with her because of this so much has already been written (plus there are comprehensive, embedded in the process of installing Windows 9x, help system).
