This is a how to DIY video that will teach you to make a 5 volt flashlight Mod for the Joye 510 electronic cigarette. The mod I teach you how to make I call the "Detonator" iut is a consistant 5 volts. Every time you vape the 2 cr123a batteries give you exactly 5 volt because of the inline voltage regulator. Other e-cigarette mods deliver 6 volt or more then slowly drop off as you use the PV, every hit the batteries become weaker and weaker slowly giving a lesser satisfying hit during use. The Detonator operates consistantly at 5 volt for the entire life of the rechargable protected cr123a batteries. This Detonator in the video has a red LED lit when the power is On and a blinking green LED when the attomizer is being powered. I take you through the process of making a 5 volt Detonator step by step, so that you can make your own. For those that don't want to make there own I will make one for you- just contact me for details.

tvrepairinfo.com In this video I demonstrate the value of a watt meter and how you can use a variac to help you test voltage regulators. I also talk about the serious potential of damaging sensitive electronic components from an electrostatic discharge. This is something every repairman should be cautious to about. Ifyour a professional looking for more understanding on how to repair LCD TVs or an electronics hobbyist here are some great resources. Troubleshooting & Repairing LCD TVs by John Preher at http For someone new to electronics the first few pages of this book may be a bit challenging but the majority of this book is easy reading with lots of pictures,diagrams and useful troubleshooting techniques. Johns book gives you a good idea about the main test points you should look for and their approximate voltages. ======================================== How to troubleshoot and repair Switch Mode Power supplies by Jestine Yong at davestv.jestinemichellepow.click2sell.eu This book is a bit spendy but I'm still glad I purchased it. In my opinion it's a must read. Jestine is good at getting right to the main points you need to understand about troubleshooting this kind of power supply and its associated feedback circuits. Since a majority of the problems I have seen on LCD TVs are related to bad power supplies I figured it will pay for itself many times over. Most of the book was easy reading with plenty of pictures and diagrams ...

Hi, Recently I read a review about Gigabyte releasing some new X58 chipset series motherboards to accommodate some future updates such as 32nm Nehalem etc, but one item I am still unsure about is 24 phase power. This is reviewed as being very important and an industry first in motherboards. After looking up online it seems to play a part in the power going the CPU and will help in over clocking although I am still a little confused. ~Andy

LED power driver on the basis of LM317 chipLEDs have become very popular lately. They are used to light up pretty much everything.However, LED is quite a fragile component. It can break when affected by voltage drops, continuous operation in peak modes, and incorrect connection. It is important to know that LED's main longevity parameter is not its power supply voltage but the current which flows through it.I'd like to show you a simplest current regulator which is quite reliable at the same time. It can be easily used in various feed circuits of LEDs.The circuit of such regulator is quite simple. To stabilize voltage "ajust" terminal is usually connected to earth, through a resistor or without it. In this case it is connected with a regulator output.So you can see that you need only one resistor to transform LM317 chip into LED power driver!Rated value of the resistor can be calculated with this simple formula. So we'll have 62 Ohms of rated resistance for an LED with a 20mA current. The chip's maximum input voltage equals 37V. That means you should use the regulator for voltage up to 37V.The only condition that you have to follow is that you must select the number of LEDs in such a way so that the regulator has as little voltage left as possible - but no less than 1.3V. This is necessary for reducing dissipated power on the regulator itself. It is especially important for large currents.And do not forget to install a chip onto the radiator at 350 mA currents or above.

Video showing the difference in the power consumption between a linear voltage regulator and a switching voltage regulator. The 'switcher' is a TL2575HV in a TO22x package. Both regulators are 'bucking' 13.5VDC to 5VDC. The difference is like that between day and night. Enjoy

I modded the airplane so that the X-Port can power the video camera. The camera now weighs much less (without batteries) and so it can go much higher. I also upgraded the battery to an 8 cell. This is the highest I have flown with this airplane. It took about 8 minutes to go as high as it did and then took 8 minutes to glide back down to the ground. A few times the engine cut out because it was getting out of range. The camera lost power about 30 seconds before I landed. On the way up I flew with some hawks that you can see if you watch closely. I think about 5 of them were circling because of the farming work going on near by stirring up the mice :-). I got up high enough to see the Columbia and Snake (if you look closely) rivers. I used a 5v linear voltage regulator from an old hub, a floppy power connector from an old pc power supply, and a dc plug from an old portable cd player to make the power adapter for the camera. Next I am going to add a magnetic fish-eye lens to the camera.

with Jim Williams, Staff Scientist video.linear.com Most circuit designers are familiar with diode dynamic characteristics such as charge storage, voltage dependent capacitance and reverse recovery time. Less commonly acknowledged and manufacturer specified is diode forward turn-on time. This parameter describes the time required for a diode to turn on and clamp at its forward voltage drop.

this chip can give you a regulated output from 1.5V to 13 Volts output... in put is 1,5 to 37 volts i think..... you can also buy it as a regulated output of 5 or 12 volts and others.... neg value chips also..... output is 1.5 amps......transistors can easily add up to 3 amps..... these are also control parts of bigger circuits. i will add this to my PWM to control the voltage to the main circuit.
