Adjustable zener diode TL 431A, or Constant Voltage Source.

Build Your Own High Accuracy Reference Voltage Source Using TL431A, or Variable Zener Diode Circuit Diagram, or Constant Voltage Source using TL431A, or shunt voltage regulator circuit diagram, Adjustable Zener 2.5V to 36V.


Hello friends this circuit may useful for your electronics projects because this can provide very high constant voltage however output current is very low. Also you can set the output voltage as your wish just change those 22k and 82K resistors. You can use variable resistor for manual adjustment. Don't forget to use the 4.7K resistor for current limiting, because this TL431A adjustable zener can't handle more than 100maH current.

3.7V Lithium-ion battery charger with battery full indicator without IC

Image
How to make 3.7 volt Lithiun-ion Battery chager with full charged indicator without IC. By AMKP40 technology. This circuit work perfectly with 5V DC adapters and 3.7v lithium-ion battery. If battery is fully charged with 4.267v than RED LED turns off that means battery is fully charged. If you want fast charge your battery, you just change the resistor behind this diode. Also you can  adjust which voltage you want to show battery is fully charged, just rotating the 1K veriable resistor. This circuit Diagram is personal of AMKP40 technology [YouTube Channel].

 How to make a fixed frequency 108Mhz FM Transmitter Circuit or Simplest Walkie Talkie Transmitter Circuit at home; by "AMKP40 technology" YouTube. Friends this is a very simple stable frequency 108Mhz FM transmitter circuit diagram. In this circuit you can use 3.7V battery to 12V battery still perform this circuit fixed 108Mhz. If you use a 2N2219 transistor instead BC547 transistor you can get maximum range (approximately 300 meters) with a long antenna. You can build this circuit any structure or shapes without a problem.
