Under the heading “advice to the Modeler” magazine “modelist-Konstruktor” No. 11 ’01 published material on how to adapt the radios from cheap toy cars of Chinese production to the remote control equipment, which is lacking in the circles of children’s technical creativity. Penetrating the essence of the proposed technical solutions, I came to the conclusion that the chip KY011 encoder base of the transmitter with a more efficient application allows you to enter two more commands through the use of the 1st and 6th “back-up” pulses.
RADIO COMMANDS WILL BE MORE!
Often the users PC, with a passion for technical creativity, we have to make copies of drawings and face several specific problems. The paper, which made the original, sometimes it’s yellowed, stained, stains. Or bad the scanner reads the image.
I want to share one small advice. I have an old, since Soviet times, wall clock Mayak. In General, a good watch and was exactly, and a good design, and well preserved externally. But one day they suddenly started to lag, and then stood up. First, changed the batteries, cleaned contacts — nothing helped. After an unsuccessful repair, I was told that they have long no parts and, in General, the road them to the dump.
If you find that the remote control system (CDS) import the TV starts to fail, the first thing I usually replace a power supply in the remote. However, it is unlikely that the performance of the system was then restored fully and permanently. Often TVs continue to “act up”: require precise aiming of the remote, not controlled from great distances, do not work with the first button push…
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.
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.
(Experience in Windows 9x). 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).
It seems that in our country starts to revive the system of renting household appliances. Hence, people with modest incomes the opportunity to use, say, digital photo and video equipment, previously inaccessible because of its cost. But if there is a technique Kodak, Sony or other well-known firms, whether to restrain themselves in the quest to understand: what is it so prized?!
