Voltage regulator tutorial & USB gadget charger circuit
Posted Saturday, March 9, 2013 in Charger, Circuit, Gadget, Regulator, Tutorial, Voltage by Mary Farrell
Voltage regulator tutorial & USB gadget charger circuit Tube. Duration : 6.47 Mins.
This video covers the basics of linear voltage regulators - what they do, how to wire them up, and where to find them. Then I give a basic example of how to build a 5V supply that can be used to power USB powered gadgets. Don't forget to subscribe! This video builds on material covered in my tutorial on building unregulated power supplies: www.youtube.com

Simple SEC 3- Running on Low voltage and wireless circuit boost Video Clips. Duration : 3.83 Mins.
This is an update on my Simple SEC circuit.In this video i use a 1.5v emergency mobile phone charger which boosts a 1.5v AA battery up to 5.5 to run the circuit.This works really well and also makes this more reproducable.. I have not measured the amp draw off the charger yet. I also show that the wireless reciever circuit can be boosted by adding a trigger transformer and substantialy increasing Led brightness.

Voltage Converter 12V-220V 150W Tube. Duration : 2.47 Mins.
Voltage Converter 12V-220V 150WIf you are going on a car trip, you will definitely want to take with you all sorts of photo, video, multimedia devices, cell phones, etc. And all these devices may need power supply. And how can you provide power supply in a car? This can be done in two ways: you may buy in good time a lot of different chargers for each of the chosen devices that can run from a 12 volt car network, or you can just take all the standard devices that are powered from 220 volt network and this small device, called DC-AC converter. With the help of this device we could convert the 12-volt car voltage into a standard 220 volts AC, as in domestic power supply network. Now I'll show you how convenient and easy-to-use this device is in a car. This DC-AC converter is small and won't burden you during a car trip. Due to its low power of 150 watt it is optimal to charge the batteries and to provide power supply to all kinds of low-power devices such as cameras, camcorders and more. And at the same time, unlike large power transformers, it can be used in the car, being connected to the car cigarette lighter, and it will work both while driving and while parked without discharging your accumulator. In addition to the 220-volt output the converter has a 5-volt USB output. This output is now more and more popular for charging various multimedia devices. So, it is a small, but very handy device that can be kept even in a car, will always be your car-trip assistant.
