Diy digital voltmeter panel meter 0-50V
Friends interested The cheap digital voltmeter using CA3162 and CA3161 very much. But cannot buy ICs since it is very ancient. Now there is digital voltmeter panel meter that easy to use as Figure 1 is 0-50V scale. Display with LED 7 segment. In cost 3$ dollar only. Figure 2 …
9V Low Power Switching Regulator by IC RC4193
This is the Power Switching Regulator 9V Circuit that is low current power output and It has strong point is the voltage input change from 2.4V to 10V but a constant voltage output 9 Volt. We used the RC4193 Micropower Switching Regulator is the base, easy to use and there …
