Make a power supply using LM317
The LM317 is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5 A over an output-voltage range of 1.25 V to 37 V. It is exceptionally easy to use and requires only two external resistors to set the output voltage. Furthermore, both line and load regulation are better than standard fixed regulators.

DIY Kit 2- Heart Shaped Multicolor LEDs Flasher DIY Kit
This is yet another heart-shaped multicolor LED flasher DIY kit. The soldering process is pretty straight forward. The silkscreen label should guide you through soldering. It takes around half an hour to build the kit and basic soldering skill is enough to build it.
Mode of NE555- Astable
This circuit has been configured in Astable mode. The output pulses are determined by the values of resistors R1, R2 and the timing capacitor C1. The formula for the frequency of pulses is: f= 1.44/[(R1+2R2)*C1].
The high and low time of each pulse can also be calculated.
