The Amplifier on the basis of the operational amplifier OPA2107 was purchased on the basis of two considerations. I sometimes do not have enough volume when watching movies on the computer while listening to the sound through headphones. You can buy a higher quality sound card or external DAC with amp, but I decided to do "little blood". the second aspect, sometimes I think my portable player can't "rock" headphones. So was wondering will the sound better when using an amplifier. Based on the second aspect, was chosen the portable version of the amplifier with power from the internal battery. Read more
The Modern market audio equipment and accessories, provides a wide range of expensive (and very expensive) devices designed to satisfy even the most demanding audiophile. But in the market there is also an even greater number of products targeted for the mass market. Yes, these products are budget — and not allow you to implement what you can of their expensive counterparts. But they and other tasks are more mundane, but no less important (for example, to play the role of the headset) . In this review, we met with yet another new product from Chinese manufacturers — headphones HYPERSENSE Eclipse HEX02 Read more
I Hope everyone remembers the last mile problem, which is actively decided in the beginning of zero? Today the issue is considered closed, but... Like me. Live now the private sector. There is only one provider with constant glitches, equipment repairs, server migration, cliffs and got better cables (just so you understand – the street is a normal twisted pair for internal works) and so on. No other service provider does not want to us their communications, so normal Internet is huge ... strained. Read more
Greetings to all! some days testing A5X MAX. The device attracted the attention of relatively low price and normal characteristics for the future. "Rockyboy 64-chutny processor is quite good, though running on 4 cores and loses in performance OCTA-core counterparts, but does its job well, and memory is set to the eyeballs: 4/32GB — bond for good middling good and it should be enough for a long time."-I thought. However, whether all so smoothly? On the one hand, single-band Wi-Fi and network connector Gigabit + video card not the new — Mali-450, although it supports the latest codecs H. 265 and VP9, as well as plays back 4K video in 60 FPS and other formats. On the other hand, the router in the apartment, where it will also be used single band, generally the...
The Last time THAT your Sivkov held in July last year. Under the replacement went the oil, air filters and cabin filter. Oil and air the engine was able to find the original cabin filter I bought a InterParts. Since then passed nothing at all – 4 thousand km, but I noticed that the salon began to penetrate odors. And our city is not polluted and the filter of the coal, but in the private sector with stove heating and minibuses with diesel engines ride was not comfortable. raised the question of early replacement of the cabin filter.

The Desire for compact size in modern electronics was the cause of the M. 2 standard. This form factor at the initial stage was called NGFF (Next Generation Form Factor) and came to replace the mSATA and Mini PCI-E connector and used a physical dimensions PCI Express Mini Card. The M. 2 standard allows for a variety of module sizes, both width and length and is most commonly used for solid-state drives based on flash memory (SSD) in a compact devices such as ultrabooks and tablets.

Often, for power electronics projects require a separate power supply. Personally, I have stockpiles of low-power transformers has ended, modification of the ballasts of energy saving lamps in the power supply does not always give a satisfactory result, and tinkering with them sometimes takes a lot of time. the way out can be buying used power supplies, with quite decent characteristics. Today the culprit would be the PSU at 12 Volts at 2 Amps load. Who are interested, I invite under kat. Read more
Moonshine I'm doing a little more than a year and several times during this time did moonshine from grain mash, but I cooked them in the so-called method of cold saccharification (Hawes). With a hot saccharification (STATE) chose not to contact because of their fishing experience I know that to cook a lot of porridge in a large pot without burning very difficult. But if the porridge will burn, the taste of the final product will go bad and fix it, even multiple distillations would be virtually impossible. So what is hidden under the obscure abbreviations Hawes and STATE? Read more
Continue to overlook the headphones from a new (to me) brands. But this time it's SGZ-DN1, BGVP. As is known — in hybrid headphones, low frequency replies a dynamic driver, but for high reinforcement. For the medium frequencies can respond to both dynamic and armature driver — dependent model headphones, and their genre orientation. But it's not enough to just cram into one body radiators of different types. We must also be able to customize. This leads to the fact that hybrids are starting to reach their potential with $100 and above. In the budget segment, so the headphones have not sweet. In most cases, they lose the sound good dynamic lugs for the same price ($30, $50, etc.). But this does not always happen. Sometimes manufacturers release products that...
Many will agree with me that in the winter to use a smartphone or tablet extremely uncomfortable. Even a simple response to the call makes to remove his gloves. What to speak of the situations when you need to write something in the social. network short discomfort quite a lot.

Decided for the winter to be prepared in advance, thought in the end of December should have them, but in the real world received in late February. Probably drove drunk Chinese Santa :) Read more
Going on a long journey, I'm primarily concerned with the state of charge of their gadgets. Want at any time to be in the "zone of access", and unlimited access to multimedia functions of the mobile – listen to music through the column, to view the information in the network. In this case, for me powerbank, which provide energy not only my devices, but friends. Therefore, when the Search company released a new series of portable battery Power Storm, decided to add to their collection, when testing a single instance. It has a capacity of 10000 mAh, USB Type A/s, also supports several types of fast charging. All this "good" is based on the battery type 18650, placed in the body of anodized aluminum. Read more
In this review, I suggest to get acquainted with the Radeon RX580 4G D5 GAEA from the Chinese manufacturer of computer components Yeston. I will not give performance tests of the system-wide or game problems, I will focus on the optimization of this model in the mining of Ethereum cryptocurrency. And Yes, the video card was purchased at a discount in the expense of writing this review, p. 18 available. If that doesn't scare you, and if you want to know how the sewn cards from AMD – I ask under kat. Read more

Dunu-Topsound not too often pleases us with another headphone. One of the reasons why it happens is the manufacturer a lot of time and effort invested in the production of the new model. Development and debugging, can take years. In the end, (in most cases) this has a positive effect on the quality of the final product. Less is better. Dunu Falcon-C are designed to fill the niche between top-end Dunu hybrids DK-3001, and relatively budget Dunu Titan. Try to understand — what kind of a beast, this Falcon from China. Read more

The manufacturer, as from the designer gathering ground: motherboard + CPU, memory chips, camera modules, battery and prepares it in a nice case. And here begins the most interesting. What would the end product is better sold, brands third tier follow the trend and copy fashion pieces in their models. In General it has always been, is and will be. As only a global leader like Samsung or Apple comes up with something new, so once the market is flooding a lot of models, offering similar features but at an affordable price.
