Get 12 Volts out of 5 Volt computer USB port

If you are running out of idea where to get 12 Volt source of battery to power your mini project - never look too far or thinking of buying expensive 12 Volt battery. There is 5 Volt USB port on your PC or laptops or maybe power bank. There are also AA batteries, 18650 batteries, etc that you can boost step up the voltage up to 12 volt. The circuit is using the LM2577 step up DC to DC boost. The circuit is quite simple yet it provides good enough power to use in small electronic projects. The circuit diagram came from Texas Instrument datasheet which states that it can output current as much as 800 mA which is quite powerful. Most small electronic project is enough to run on those small amp.
