This is my small joule thief circuit with a 2N2222A transistor, a 1K resistor, a small bifilar coil and a single 1,2 volt rechargeable battery. In this video the circuit lights up 20 ultra bright 10mm LEDS and 4 bright 5mm LEDS, all in parallel. At 1,28 Volt the total of 24 LEDS only draw about 60 mA while each single LED is rated for 3,4 Volts and 25 mA !!! That's what I call efficient. The ferrite core with the small coil is recycled from an old PC power supply, all I did is that I added a second coil with 20 windings, I just wrapped the wire around the first coil. It's an amazing circuit, very efficient. I was inspired by many people but the first video that I've watched about the joule thief was from Youtuber Lidmotor. Be sure to visit his channel, he has great videos. * www.youtube.com Also check youtuber JohnnBlade * www.youtube.com Peace, InsAneTunA

The Babyview 20 by Levana incorporates all of the key features that you would like to find in a baby monitor. In fact, it has a few feature that you might not expect - such as the ability to play lullabies directly through the camera. Pros- - Voice Activated - will turn-on when the camera detects noise or movement - Will play lullabies through the camera and is controlled through the monitor - Awesome mounting brackets and swivels - trust me - this may save you a lot of grief in positioning your camera. - Manual night light - The monitor has built-in rechargeable batteries - Monitor is small and light enough to be clipped to a belt - You can control the brightness of the display screen on the monitor. Features not present - Will only support one camera - No A/V output (again on units that have A/V outputs I have never used the feature). - I have had some issues with range, but I think it is more likely caused by something within our home - since the unit works in 95% of our house (and some nights we have no issue at all). Note - most of the other reviewer's have not had an issue with range. - The color response is not great, but this is not that big of a deal. The main is that you can see your child in both well lit and dark conditions. Final verdict - the BabyView 20 is a feature rich and reasonably priced. It certainly is worth consideration for your nursery! 4 Stars - Please note - I was provided one unit from the manufacturer for review purposes -----

With solar powered lights are so popular, there is a good thing to know that in most cases, lighting sets are equipped with batteries for solar lights. In practice, the batteries are charged every day when the sun rises to ensure that the lights are working properly to continue.

Some people are under the misconception that if the day is cloudy or if maybe the sun is in full force and batteries for solarThe lights do not work. Fortunately, the batteries can hold a charge for more than a week. So this means that when the sun comes out, even a day for a couple of hours, you will be charged and the lights are also functional for at least a week, even if the sun peaks is the head again.

The fact that the battery can hold a charge for so long is actually a key factor in the fact that the lights are so easy, it's almost in every yard you can think of it. When the light hit the first solarpeople thought that the scene only to install lighting in the places the sun directly. However, it was not long before the consumer has been educated to function correctly, that time until the batteries have been exposed to the sun for a short period of time that the lights are solar would pay well and would have done.

If you buy a set of solar powered lights in most cases, an additional set of rechargeable batteries is also, so that inIf a battery fails or is not working as it should, you have a backup copy, which is at hand and ready in stock.

The batteries for solar lights must be placed at all?

Unlike other types of rechargeable batteries, solar lights are never required, nor are they so be constructed in advance of origin is that an electric or allows them to pay with traditional. They are so effective that even on cloudy days, there are enoughSunlight passes through their full charge to make sure you have set your continued use of lighting.

So if you ever worry or concern in Going Solar by virtue of a sort of confusion on the batteries for solar lights, I hope this has helped to educate and understand the advantages and opportunities that this creates illumination.
