According to FEMA electrical fires kill almost 500 people and injure over 2000 more. Most are caused by poor maintenance of electrical appliances, incorrectly installed wiring, overloaded circuits and extension cords. The holiday season is quickly approaching when we all start to decorate and use our electronics more heavily. In fact, I have already seen Halloween decorations in many neighborhoods. This is a very relevant topic as December is the most dangerous month for electrical fires. I have made 3 quick tips that you can try that could protect your precious electronics and perhaps even your life. 1) Don't Daisy Chain Power strips This is more common than you think. Daisy chaining power strips is when you plug one power strip into the other. I'm not sure why but most people feel comfortable doing this but it is a bad practice. Daisy chaining results in a spread of the potential surge overload across both strips evenly. Where an overload of X size would trip one power strip, when two are connected 2X the overload is required to cause a trip to occur and so on. In short this practice puts everything you plug into the power strips at risk. It's just not worth it when a good quality extension cord can solve the problem. 2) UPS for Desktop Computer Power surges and brown conditions can burn out computer power supplies and even cook the computer all together. At minimum a new computer power supply is around $100 to replace and if your computer gets fried, well then there's ...

Один из самых популярных стабилизаторов напряжения LM317 обеспечивает выходное напряжение от 1.25В до 37В при токе в 1.5А. Как правило, для установки выходного напряжения применяют переменный резистор. На приведенной схеме показано, как заменить переменный резистор аналоговым напряжением, формируемым из сигнала ШИМ. Параметры широтно-импульсной модуляции могут устанавливаться внешним контроллером или другой цифровой микросхемой. С помощью RC фильтра низких частот и операционного усилителя можно преобразовать сигнал ШИМ в постоянное напряжение, и тем самым, регулировать напряжением выходной уровень стабилизатора LM317. Изменение скважности импульсов ШИМ дает возможность генерировать аналоговое напряжение на выходе фильтра в диапазоне от 0 до 5В. Операционный усилитель усиливает это напряжение для получения требуемого диапазона. Меняя значения номиналов резисторов R4 и R2 можно получить требуемое усиление. Выбор номинала емкости С1 и резистора R1 фильтра определяется частотой сигнала ШИМ. Номиналы, указанные в схеме, рассчитаны для частоты 1кГц.

First of all, for the observant I must say that I did use a non deepcycle battery, but it was free and this project is still at the experimental stage, I'm not even sure how long the brown wooden box will last or the handheld generator or those kitchen spoons, but time will tell. This run of the river project is insanely inefficient mainly because of the half inch hose, which should really be 90 feet of 1 inch PVC, but the materials were easily acquired and installed. After I've watched this project for a while I'll more than likely upgrade the main components as they breakdown. Also it's really important to add a fuse or a low amperage breaker at one of the battery terminals simply because the odds of a mouse chewing through the wires or a tree falling over them in the next 10 years is huge. Most of these batteries can put out enough cold cranking amps to catch any log cabin on fire or create a forest fire. The hand generator only makes about 3-5 watts of hydro electricity per hour and therefore does not need a voltage regulator but is just directly hooked up to the 12v battery and functions very much like a trickle charger does. A DC to AC inverter may be hooked up to the battery terminals if you want house voltage, though I recommend attaching a switch to it in order to turn the inverter off when it's not being used in order to save power. The funny thing is that most of my electricity needs are 12vdc, including that 13watt CFL bulb so I might never hook up the ...

One of my friend have some trouble with reworking smd voltage regulators so I made this video for him. The hard thing is the back of the component acts as a heat sink and It's soldered to the board. A soldering iron useless in this case, but the solder paste and hot air are good for this.

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.

I'll just mention again that if you own or can borrow most any functioning Ignition coil and 2 spark plug wires off a car or truck, you could use them to test start your engine. I've expanded below how to wire up the coils + and - wires. Then all you'd have to do is rig both spark plug wires together into your coils single output. Your engines original coil fired both spark plugs simultaneously just like this, it just had dual spark plug wire outputs. Ok cool, its a 77. Below is the correct 1977 schematic and I've updated my wiring identification info from my previous post: 1- Rectifier ground wire (I'd connect this to the same location your negative battery cable bolts to the engine) 2- Rectifier power feed (connects to + side of battery) 3- Rectifier. (It converts A/C to D/C voltage) 4, 5 and 6 are the three AC-voltage legs coming from your engines charging coil. (looks like that plug just went bad and they bypassed 2 of the wires around it) For now your engine would start and run fine without #1 through 6 or #12 connected. (they're all just to charge ...

with Kelly Consoer video.linear.com Modern FPGAs and servers operating at low voltages are sensitive to subtle supply drops. The droop may result from a combination of excess regulator noise, insufficient bandwidth in the supply regulator, excess ESR & ESL in the decoupling components, or distributed inductance in the power distribution. To abate the risk of supply droop the typical approach is to surround the processor with an assortment of ceramic and bulk capacitors, thereby lending broadband support to the supplies with capacitors. This consumes board area and component budget. Linear Technology's LT3070 is a POL regulator designed for FPGA & server applications. The LT3070 commands high bandwidth and fast transient performance by providing lower output impedance than bulk capacitors, thus eliminating the need for bulk capacitors. With the LT3070, the distributed decoupling network is reduced to just a few small ceramic capacitors. The high bandwidth combined with a 25uVRMS noise floor, make the LT3070 the fastest, quietest, lowest dropout, and most cost effective 5A monolithic linear regulator in the industry.
