本机主要由LA1050集成电路和太阳能电池组成的调幅收音机。该机电路简单,容易制作。由于电路中加有大容量电容器和镍镉蓄电池,所以夜里在暗处也可使用。收音机不用的时侯还可以将收音机放在阳光下进行充电。附图是电原理图。整个电路可分为两个部分。电源部分是利用太阳能电池对大容量电容器充电,为收音机提供电能。在太阳当头的光照条件下,太阳能电池可给出约4V的电压。为了便于储能和在光照差的条件下收听,本机还可通过镍镉电池提供1.2V的工作电压。收音部分采用收音专用IC LA1050,其输入信号端接入调谐电路即可工作。LA1050耗电极少,即使不用镍镉电池,仅靠充电电容器的储能来收听,也可工作一段时间。制作:本机可装入盒式磁带内。盒右上角安装可变电容。LA1050和其它元件可安装在铆钉板上,也可自行设计印刷电
This machine is mainly composed of LA1050 integrated circuits and solar cells AM radio. The machine circuit is simple, easy to make. Due to the circuit plus large-capacity capacitors and nickel-cadmium batteries, it can be used in the dark at night. When the radio is not used, you can also put the radio in the sun for charging. The figure is an electrical schematic. The entire circuit can be divided into two parts. Power part is the use of solar cells to charge large capacitors, to provide radio power. The solar cell can give a voltage of about 4V under the sun’s light conditions. In order to facilitate energy storage and listening in poor lighting conditions, the machine can also provide a 1.2V operating voltage through a nickel-cadmium battery. Radio part of the radio IC LA1050 dedicated, the input signal terminal access to the tuning circuit to work. LA1050 extremely low power consumption, even without nickel-cadmium batteries, charging capacitor charging to listen, but also for some time. Production: The unit can be loaded into a cassette. Install the variable capacitor in the upper right corner of the box. LA1050 and other components can be mounted on the rivet board, but also design their own printed electricity
