Light wattage with their wattage is not directly related and linked to the light output in lumens per watt. Light output varies in light of various designs. Therefore evaluate luminous power of the lamps at their wattage is possible only within the same group.The most common types of battery (ie rechargeable, internal battery) lamps as a current source elements used sizes R20 (D) (in use — "large round battery"), R14, R6 (AA) (colloquially — "penlight batteries"), R06 (AAA) 1.5 V or volt battery 3R12 nominal voltage of 4.5 volts. Amount of elements — from 1 Read more [...]
For the production of USB charger can be useful for us:USB extension cable (any length, even 5-10 cm),the cartridge on 4 AA batteries (took in the market),dyadic (taken from a dead power supply),palenicek slightly flux and solder (30 minutes)multimeter (30 minutes)sealant or thick glue.The principle of production. From USB extension cable, leave only the socket with wires. It must be attached (e.g. glued) to the base of the cartridge, and the wires coming from [+5 VSB] and [GND] contacts of the USB receptacle, solder to pads [+] and [-] cartridge, respectively.The cartridge on 4 AA batteries (FIG.

Graduate of the Tomsk Polytechnic Institute (TPU) Dmitry Prokopiev has developed a nuclear battery, which can steadily and without charge to operate for about 12 years and used in medicine, military equipment and space.The student noted that the power of the batteries is much less mundane parts supply, but it is capable of without charge to work 12 years - this time half-life of tritium."In a sealed enclosure filled with tritium, put arsenide 3D detector, modifying the energy of the beta particles emitted by tritium, in the electronic current. In the sensor created an unlimited number of wells. Read more [...]
Today we have a favorite subject, solar panels.
Part One Fuel generators and fuel storage
Part two Stirling engines
Part Three Thermoelectric Modules
It is estimated that if in the Sahara Desert to place solar panels on the territory of 160 square kilometers, it is possible to completely abandon all other types of energy sources and oil, gas, uranium, water, wind and so on.
Solar panels are composed of silicon.
Silicon is the most abundant material on earth, for example sand.
So for what is the problem?Many of us do not realize that a method of producing electricity from sunlight is known Read more [...]
Hello!Gone are the days when capacity rucksack limited only KOSTROVA and bedding yes guitar at night campfire.
increasingly in outdoor driving digital assistants accompany us: cameras, navigation devices, lights and more.therefore raises the question of supply of quality and reliable batteries, when the field is not possible to charge them or buy new ones.Today we consider the most common format, penlight batteries and accumulators or to put it in technical terms-AA batteries.
it is no secret that these "fingers" can now be purchased at any bakery and tied them to a good half of all electronic Read more [...]
Just like always. While roasted rooster does not bite ...
In general, the light is turned off as the phone sat ... you wonder how to do so to telefonchik charge. And he did. (Certainly not immediately )Took the cord from the UPS cut unnecessary end and fastened thereto outlet.Test charge number, naturally everything works.
But I poshol little further and soldered here such an adapter. Wire, two crocodile and two poles "dad"UPS took the lid off, disconnect the battery iprisoedinil avtomobilnyy.Vklyuchil staff ... work ...My UPS power 300w, so that the devices up to this limit think will Read more [...]
Hello dear members of the club will survive.I want to share, c you, another option at TC scribe.]
Two years before the "electrification" went on the pedals, but each time to overcome 35-40 km to the back garden and was not in a rush. In March remade his favorite horse STELS 710 Navigator. In this electro-beast 1 HP (750W) to speeds of 55 km / h One charge just enough for 40 km. Still not naraduyus.First day on the moveCan be charged from a windmill, mini hydro or solar panels. Need a voltage 50V and up to 4 amps, ie ~ 200W (or less amps, but on the 1st amp, for example, is charging Read more [...]
Part of the 3rd Electricity after BPSo, comrades, the most pressing issue - production of electricity . Just say, I will consider only the mobile versions, ie that can be put in a backpack. Benzo bicycles, wind generators can choose. The only advice on Petrol, take exit to 12V (avtoprikurivatel), in this case, the mobile device can be charged as efficiently as possible, without losses double conversion (first at 220, then from 220 to 5V).
To date, the Internet is full of electricity production methods, from classical to very exotic or sophisticated. Especially encouraging people who are stuck Read more [...]
Part 2 Electricity during BPIn this part, we consider how to use the stored energy or Marauder
Consider the options that can get in different situations.
1) Work with regular batteries
Charge equipment from conventional batteries can use a variety of devices.KOS-518 device (interesting Chinese device, review here www.youtube.com/watch?v=AQ4-wBttKKQ). May charge akkumy and give energy to the load.iBest CS10 (for 4 batteries)That's what I do not recommend, is to use all the "ammo" on one battery! Useless device for modern devices, well Accum to 300mA / h it is still able to shake the Read more [...]
I want to introduce you to a useful shtukentsiyu as under barrel flashlight Night Hunter.
It's no secret that night hunting for hare and other animals is more efficient than fluorescent. But requires a few more light equipment. Just one of them is the lantern night hunter. From personal experience I would say that hunting brings with him a very tangible results.
Well, so how to survive will be held in harsh conditions and all with a grub will not carry away. Hunting is a natural forage on the way to a brighter future. All the specifics of the night hunting will not describe, because it is pure Read more [...]
Knowing my hobbies, friend gave lantern. this big.
LED Flashlight Benex Solar + dynamo (ET-0640)
Potestá in the campaign, give my personal opinion. In the theme of "Lights" someone wrote that it would be good to combine a flashlight solar battery, dynamo and batteries.
I can say, not the best option in mind the different requirements to the lamp depending on the tasks.
Sam needs of tactical use nalobnik for night transitions in the campaign or parking in the woods. If shine far and bright - I use the grenade launcher.Now about the actual «Benex».
The main disadvantages:
1. Solar cell - a Read more [...]
For more than a year, I read your great articles, reviews and reports, but to this day he remains in the shadows. But today decided to make a small contribution to the total, so to say, the case.I'll talk about lanterns and, in particular, one of the best (in my opinion) for everyday wear in any conditions-NiteCore EA1. I strictly do not judge and take condescending to my first publication.So, a short introduction:
A few days ago (to be precise, the New Year's Eve) son overcame me, my faithfully served me a few years lantern (surprisingly high quality offspring Russian-Chinese Read more [...]
Nadybal today old flashlight.Front view.And here is the battery compartment.So seemingly normal flashlight batteries in but it is enough for three days of continuous operation (when it is fucking expensive disposable batteries). And to me it's a little more than a flashlight and decided to stir up the battery. Battery took the phone, I'm sure it is completely dismantled and left the battery itself. I c battery capacity of 2500 mAh. and a capacity of about 9 watt. It is excellent performance for flashlight which consumes 50 miliamper. And here is the battery.So begin. Parse Read more [...]
Good day! I would like to tell you about a homemade device for charging mobile phones, tablets, e-books, and other devices can be charged by USB.
Homemade, it certainly can be called conditionally because it is actually assembled from components purchased from China online store.
So, for the manufacture of such a device was purchased by me:
1. Boxing for two batteries type 18650 - worth $ 0.98.Pokupal here: www.buyincoins.com/new_en/details/plastic-battery-storage-case-box-holder-for-2-x-18650-black-with-6-wire-leads-product-9160.html2. Step-up voltage converter - worth $ 3.61 I bought here: Read more [...]
I went the other day, in one of the local shopping center of the spill, and just could not resist shopping. All there cheap, only that there are many. And out of the mountain range, I chose only three things that interest me the most. Strangely enough, all three items were originally from China. Their review I give you.Item number one - Cycle Solar Lantern.I bought it at the southern exterior of the men for a very modest 350 rubles (it was originally requested 550 wooden). Flashlight was packed in a plastic envelope with a normal piece of cardboard behind. On cardboard figures depicted (in Read more [...]

Recently read a very interesting publication.
I think it will be very useful for site visitors.Big test batteries
Every time you buy batteries, I thought: what better. There are plenty of batteries around the same price, there are cheap batteries that are sold only in certain stores - Ikea, FlexPower, OK, there are expensive batteries Duracell, Energizer. Is it always better to expensive batteries cheap?I have long wanted to compare the batteries and finally I did it.For our test we used iMAX B6. Each battery is discharged to 0.2A current until could issue such a current. To confirm Read more [...]
