SP LED Flashlight Using Supercapacitor

Posted by kumit on 23.47 with No comments so far
Bored of joking with capacitors? Then its time for you to maneuver on to super-capacitors. These have huge storage capabilities. during this article you may conclude the way to build atiny low LED flashlight using supercapacitors.The most disadvantage of capacitors is their giant voltage drop. For this project, a minimum voltage of two volts is needed to light-weight the LED. As a result, the �

Power Supply Circuit using IC LM317

Posted by kumit on 01.30 with No comments so far
The primary part of this Power Supply circuit
is the voltage regulator IC LM 317. This circuit is ideal for power
circuits as the circuit of the power amplifier can deliver a current of
2A. In this circuit the transistor acts as a pass transistor Q1 to
increase current capacity. The output voltage is set to 40V by using
resistors R5 and R8.Parts ListResistors:
R1 (39 ohm 1
