Simplest Microphone Booster Circuit Diagram, or Basic Pre-Amplifier Circuit Diagram with Simplest Battery Level Monitor. Friends this circuit works perfectly and boosted sound is crystal clear and this circuit works very large voltage deference 5 Volt to 14 Volt DC. And one thing, in this circuit has very very simplest battery monitor circuit this single LED indicator which LED ON if battery voltage higher than 6 Volt and terns OFF if battery voltage lower than 6 Volt.  This circuit diagram is personal of "AMKP40 technology".

Simplest 12V LED Chaser Light Without IC Circuit Diagram; by "AMKP40 technology" Youtube channel's. Friends this circuit very simple and easy to make at home. You can drive this circuit in voltage between 3.7v DC to 15v DC and this circuit works perfectly. You can use any NPN transistor instead BC547 transistors in this circuit. Also you can change capacitors into lower value µF for more chasing speed of LEDs. This circuit diagram is personal of "AMKP40 technology" Youtube channel's.
