How to make 5v to 1.5v converter circuit

In this project we learn How to make 5v to 1.5v converter circuit easy at home. you can run your wall clock, your calculator and all 1.5v products using this circuit. we make this circuit only 3 componets with the help of circuit diagram. you can also convert your 3.7v mobile and litheam battery with this curcuit. 

for making this project we need some components

• LM317 Voltage regulator
• 470ohm resistor
• 100 ohm resistor
• soldering wire
  
  
  
• soldering iron

Now following this steps and make same

• LM317 has 3 pin, connect 470 ohm resistor between 1st and 2nd pin of regulator. 
• Now one side of 100 ohm resistor connect with1st pin of regulator.
• 2nd side of resistor use for negative input and negative output. 
• 3rd pin of regulator use for positive input.
• And 2nd pin of regulator use for positive output.

Total cost of this project:

Total cost of this 1.5v converter circuit is round about 0.105$

• lm317 voltageregulator price is 0.1$ in local market.
• And 2 resistor price is 0.005$ in local market.
