Radio designer `` Start-7176 '' (Electronic clock).

Radio and electrical constructors, sets.IndicatorsThe radio designer "Start-7176" (Electronic clock) has been produced since 1985 in the city of Rivne at the Gazotron plant. RK contains a printed circuit board, LSI K145IK1901, vacuum-luminescent indicator IVL1-7 / 5, quartz resonator RV-76, as well as resistors, capacitors, diodes, etc. Included in the RK kit and power supply. The collected electronic watch has an accuracy of not worse than ± 0.5 s per day. They consume 6 watts of power from a 220 V network. Dimensions of the printed circuit board 130x90 mm, weight of the watch with a power supply unit 400 gr. MC K145IK1901 is a microcontroller with wide functionality and can be used as a timer with a maximum counting time of 59 minutes 59 seconds. At the same time, the device does not stop counting the time, the information is entered into the memory, therefore, when you return to the "Clock" mode, the current time appears on the indicator again. The modes "Alarm 1" and "Alarm 2" allow at the set time to turn on and then turn off the required executive device. The microcontroller can also be used as a stopwatch. The load capacity of the LSI is small, and a signal device on microcircuits and transistors can be connected to it. If it is necessary to control the operation of the equipment powered from the AC mains, it is necessary to supplement the clock with amplifiers and actuators. The case was not included in the set. The price of the radio designer "Start-7176" is 16 rubles.
