Today, talking about the thermoelectric modules.
What is the Peltier effect and thermoelectric module?
Peltier effect was discovered by Frenchman Jean-Charles Peltier (1785-1845 g) in 1834. During one of the experiments he missed an electric current through the strip of bismuth, connected to it with copper conductors. During the experiment, he found that one compound of bismuth-copper is heated, the other - cold.
Device moduleThe advantage of the Peltier element is small, the absence of any moving parts, Read more [...]
Manual pocket saw or saw-string" exists in a huge number of variants and modifications, and is intended to complete personal engineering equipment, as well as countless sets and Nazov for the military.In practice, the saw-string is used to perform simple and easy works on the harvesting of timber, clearing sectors of fire, to overcome certain kinds of barriers and obstacles for sawing products from soft metals, plastic and bone, as part of the traps, etc.Make out the "American" version of such saws. He has a unique grip-clamps that allow you to use the saw in a "shortened" version, just pereceive Read more [...]
Remember How long you've been doing Feeders for birds??Taught whether their own children to do them?And because it is so interesting and, in principle, Nothing.. The most common feeders can be made from a package of under milk or plastic bottles, and even just from the grid, putting down the food, mixed with fat and blind from this consistency balls...( see photo 2 )At the moment, Until the Weekend, do it Either by yourself or with the whole family.. Hang feeders, sprinkle food - it's not banging on your budget.. ( kg millet is 19 rubles..etc)Do Good and Help to Survive to those who need your help Read more [...]
Today on the Stirling engine.
(A lot of interesting video)
Part 1. Fuel generators.
For so many it is unknown what, so it is a lot of theory.
Yet this wonderful invention called the external combustion engine.
The operating piston is filled with air or gas, as it is exposed to the outside heat.
So for this petrol engine is not needed, it can handle all that generates heat, sun, wood, coal, gas, oil, nuclear fuel. All where you can get the temperature difference, there are models that work even hands from heat.
Running the engine heat from the cup:Suffice it to say that refrigerators, air Read more [...]
I decided to write about energy. At first glance, the drink can be useful during the PSU and the first months after, because the times are dashing and sleep in safety will not always turn out. Just say, like any stimulant, acting on a simple scheme - take a lot of energy from the body at once, which leads to the inevitable exhaustion of the nervous system, metabolic disorders, that is, if you drank a power engineer and do not sleep for 3 days does not mean that you get away with lack of sleep, sleep to vostonovit forces have, although power engineering will allow time to find a 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 [...]
Write me spotvigla my article "To recognize the". I want to make an offer.
Sooner or later (if the site is not close or PD) will throw one of the comrades in the warm time of the call: "Let's get together, our works of Lamentations have a chat, have a cup of vodovki".How to distinguish friend from foe? Is not it time we would make logos of, order and distribute OUR? I think 100 rubles per vlozhimsya.S other hand - what a memory that was once "VYZHIVALSHIKOM" site " survive "! By the way I have it hanging in memory as Nurse jacket and overcoat with stroyotryada army! Memory In any case, it would Read more [...]

I want to offer an entertaining colleagues read an excerpt from Kalashnikov "Broken Sword of the Empire" that needs to be nurtured as real-elita.Kogda I reprinted this excerpt from the book for myself when it was not so good with the internet, now I found it and I want to share with you.The fate of the Soviet Union has taught us that the scientific and industrial power - all
only half the battle. Power primarily obliged to nurture true

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 [...]
Over the past 10 years there and became available in the campaigns are extremely useful devices. Chief among them, it is certainly:- GPS-receiver- A cell phone,- Mobile radio,- Digital camera- LED flashlight.However, these devices consume only clean electricity and have an aversion to traditional tourist energy sources such as wood, natural gas and gasoline. Today, these devices do not consume so much electricity as at its birth, there are great batteries «Duracell Ultra M3», but the problems of power supply remained.

Another copy-paste from yablokofona. Generally, there are good programs write.
"Resuscitation (animation) - is the restoration of vital body functions (primarily respiratory and circulatory). Usually death never comes at once - it is always preceded by a transitional period of time or a condition called terminal. In one case, a terminal condition lasts for a second, in the other - the hours and days. It all depends on the degree of damage to vital organs and body systems. Moreover, the changes that occur in the body of a dying man, did not immediately acquire irreversible and can often be eliminated Read more [...]
Wolves and foxes are hunters, naturally mined..For the sake of hunting excitement or for the sake of the relative abundance of feral animals (rabbits). But to roast their meat on the fire hunters somehow not in a hurry. Wolves and foxes, usually remain for hunters, though respectable, but only symbolic trophies for the photo. Carcass as foxes and wolves in the best case, take for yourself a Ranger to Petrovci dogs. And in the worst - carcasses and lie on the ground, and not even ravens peck.But all the same? Can wolves and foxes to eat food? Well, with Fox well: in almost all regions, it's almost Read more [...]

LAMP OF CANNED "Tuna in oil"" I welcome . This is my 1st attempt at video . Take canned food , tuna in oil , rope made of organic material , hemp, cotton. In the center of the cover banks do the hole for the wick. Insert the wick into the hole and well impregnated in oil. Ignited. Such a lamp is burning long enough, in fact, not bloat. Can be used for lighting or if you attach the top to the Bank of corresponding diameter to warm the tent. Thank you for your attention..."What would you say ?#vyzyvayustchimproject 1 2:54Read more [...]
It is no secret that with a bunch dragged necessary electronics. At least it's a phone / smartphone. And in the case of a minimum of PE (in PD, these gadgets can be no longer relevant) all this economy you need something to "feed". Hence the need to build vytantsovyvaetsya schemes for different occasions. Not so long ago wrote about the three scenarios and response equipment depending on the urgency of the evacuation period and autonomous existence.
All the gadgets are unified in connectors - mini or micro USB, which minimizes the number of laces. Exception - the plates, but that's another story. 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 [...]
