LM317T Voltage Regulator with Pass Transistor

This is a great solution for running LED strips when using multipul battery packs or also 4S, 5S or 6S LiPo packs. The Video is a bit long but it is complete.

Turning off and then on again problems in the first minute or so of powering up which eventually lead to not turning on at all. Model No. LE32A436T1B Here I have managed to save my mother a £180 repair bill by fixing it myself. Trawling the internet brought up a lot of 'capacitor' issues with Samsung televisions and so I was expecting to find a couple of blown caps but up on inspection all the capacitors looked fine. Looking closer I found a couple of dry-joints on a power transistor or voltage regulator (QB802 location on the power supply board). A quick solder job later and all is well again. TOP JOB!!! :)

This is an update on my voltage regulator oscillator.It will now run on a wide input range and the full output of the regulator is available for switching or pulsing applications. I also show how the VRO can be used to make an inverter and an exciter.

safepages.org Homemade Solar Panels - The best guide! Click the blue link to watch the presentation. The link above will take you to the presentation video for Earth4Energy which is currently considered the best guide for building your own solar panels. Read below for more information about solar panel systems... With the increasing awareness to promote a greener environment, using alternative energy sources like homemade solar panels are gaining in popularity. In fact, installations of these systems are increasing every year thanks to the various programs supported by the government. Examples of this are the Feed-in Tariff and the Renewable Heat Incentive scheme, which encourages the population to install homemade solar panels in their homes and buildings. Here are some of our "pros and cons" to installing a solar PV system: Cons Installing homemade solar panels requires an upfront investment with the prices depending on how large the installation will be. Return on investment for this system can take up to 6 to 10 years. Just like any other product, this system will degrade at approximately 20% over a period of 25 years. It requires more roof space to install the system. If we will look closely, installing solar PV systems has more pros than cons. Yes, it requires initial investment but over time, it will translate to bigger savings as it can help save on electricity bills. Aside from the monetary benefit, renewable sources of energy can greatly reduce the use of fuel ...

www.FreedomUniversity.TV. The video shows how to analyze an operational (op amp) circuit configured as a buffer or voltage follower. The buffer is used to prevent loading between circuits. In other words, when connecting circuits together, you do not want to change the operational function for each circuit. If you have questions, please contact Professor John Santiago at john@e-liteworks.com or visit the above website.

DC Motor Speed Control The speed of a direct current motor can in most cases be controlled using a very simple method - by changing the voltage at the output of the adjustable power supply that does not require high load current. The experience of using this type of motors showed that they are highly practicable in various fields of application, starting with anything like toys and ending with computer ventilators. Such popularity of the device is explained by that it only requires low current. Sometimes we need to adjust the rotation frequency of the motor or its speed to achieve the required mode for performing a certain task that a certain electric motor is designed to execute in a certain model or device. This is easily achieved using a regular adjustable voltage stabilizer that is compatible with any power supply unit. The basic circuit is built based on an LM317 stabilizer and several additional elements in the binding. The device is far from being new and it used in many power supply sources. However, it is very useful. Because of the low current consumption of direct current motors, even those used in computers - 250-350 mA, a stabilizer can easily manage many hours of daily load. Adjustment of motor speed only affects the rotation frequency forcing its own capacity to change in either direction depending upon the speed.

The DuroMax XP4400E says Lights ON! There are many causes of power outages, such as wind, snow, and ice storms causing fallen branches and downed power lines. In recent years storms and other power failures have caused the electricityto be out for weeks at a time, and in a few instances for several months on end. This can cause many hardships such as: freezing pipes, spoilage of refrigerated food, frigid indoor conditions and severely distressed familly members. It is no fun shivering in the dark and there is always the danger of a candle or lantern starting a fire at this worst possible of times. You would do well to plan now how protect your familly and household with a Electric Start 3000 watt generator! This portable electric generator is like having an isurance policy to cover the unforeseeable weather dissasters that seem to occur with increasing frequency in our power dependant modern world.

I was asked this by a few people and planned on making a video about this as well. I am touching base on how external regulators are installed. In my opinion, its a much better route than using a module that controls it for you (I won't mention any names) since you have full control over your peak voltage. Anyhow, new videos on the way since everything is up and running. Keep checking back for updates!
