GENERATIONS

 This IC is an inverter logic gate ic. So if u can make an inverter gate then no need of buying this IC. Resistor R1 will control the blinking speed and resistor R2 will protect the LED from too much current. This type of blinking doesn't require a fixed type of voltage so any voltage values can work as long as they are not too small of a value.

 This is a simple blinking led using a bc547 transistor. As it is in the diagram. You will need 1 transistor , 1 LED , Capacitor and a Resistor. This will work well on a 12v battery. Other types of batteries may not do the trick. The value of the capacitor will determine the blinking speeds.

 The charger works like a 500 mA iPhone charger and will work with most modern phones. The main component in this circuit is the voltage regulator 7805 (U1). This is a component that takes an input voltage of 7V or above and gives out 5V. The diode (D1) placed in front of the input of the 7805 does two things: It makes sure you can't damage the circuit by connecting the plus and the minus of the battery the wrong way around. And it drops the voltage from the batteries 1v down, from 9V to 8V, which helps take some heat away from the voltage regulator. The Light-Emitting Diode (LED) is there to show you when the charger is working. The resistor R1 makes sure the LED doesn't have too much current flowing through it. The resistors (R2-R5) are there to tell your phone that this charger supports up to 500 mA (0.5 A) charging.
