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.
If you have to saw a certain number of wooden rods with a strictly perpendicular end faces, it is advisable to pre-make auxiliary guiding means conductor.

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…
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…
Nice to soak up the sunshine, sitting in a lawn chair. However, it would also be good to read, it’s very blinding. Make a movable shelter made from fabric and pieces of wire,as shown in the figure, and the sun will not interfere with either read or doze off in the soft deck chair.
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.
