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 …
power supply regulator mini 9V 0.75A by Transistor
power supply regulator mini 9V 0.75A by Transistor BD242 and BC549C. VR1-1K control Volt output.VR2-1K control current output. If you have old equipment from tape radio will to do good. I advises that try bring build , mini power supply 9Volt all right. By I uses the transistor number BD242 …
9 Volt 2 Amp Power Supply by 78S09
Description: A simple 9 Volt 2 amp supply using a single IC regulator. Notes: There is little to be said about this circuit. All the work is done by the regulator. The 78S09 can deliver up to 2 amps continuous output whilst maintaining a low noise and very well regulated …
