How to Change the Mixer

As you know, nothing lasts forever. That mixer in the kitchen or bathroom can wear so much that it will not help. This mixer will have to change. If you looked carefully at the store shiny new faucet will again have to change the old faucet on a new one. How to do it, read on.

You will need

• Adjustable multitool wrench;
• Pliers;
• Flashlight;
• Sealant;
• basin;
• Hoses;
• Special plumbing tape.

First you need to get rid of worn out (obsolete) mixer, pre-blocking water. Open the valve on the mixer, the system to get rid of the pressure, and the remaining water from the tap is fully emerged. If you want to change only the mixer, you will be disconnected enough from it hoses. If you want to change more and hoses, disconnect them from the pipe fittings.

Usually mixers reinforce two standard ways: on a narrow or a broad-based. To remove the faucet, mounted on a narrow basis, just climb up under the sink. If under it loose enough that you can easily unscrew the nut with pliers. With the mixer on a broad basis will have to sweat a little. First, you must unleash the faucet handles. To access the nuts holding a mixer, you need to get rid of handles and even from the pads under them. You can unscrew the nuts now.

After loosening the screws pull out of the sink faucet by the wrench jaw. Noticing the gasket located between the base of the mixer and sink, remove it with a knife. Together with the seal, and dispose of the old seals with a touch of lime, gathered around the old faucet. Print limescale and other dirt can be diluted in water with vinegar or special household products.

Now you can install a new faucet. If he has a wide base, the installation is relatively easy. But if the base is narrow, you will have to climb under the sink. It is necessary to tighten the nut and at the same time to control the tilt of the mixer and its location. And for this we need an assistant. Before using the new mixer, check the possible leak, then remove sealant residue from the base of the mixer.

Programmable Digital Timer Switch Clock

This digital timer is designed for load control (start and stop) and has the ability to easy programming. The project is based on the PIC16F628A microcontroller. Turn off the device via the relay. The 110V digital timer switch allows you to program a time, turn the unit on and off. This feature enables for example at a certain time to enable any device, and then after a certain time to turn it off. The maximum time interval that can be set for the duration of the on-off device: 99 hours and 59 minutes. The project uses 16x2 LCD-display with 4 buttons for user interaction.

Schematic diagram of the timer is shown below. To control the 5V relay is used PN2222 transistor, which is controlled via pin RB3 microcontroller. Through ports RA2, RA3, RA4 and RB0, there is read state 4 timer controls. Description Timer control buttons will be lower. Standard 2 × 16 LCD-display is used to display the device status, menu and time. The display is involved in 4-bit mode and is therefore used only six I / O from the microcontroller PIC16F628A. A piezoelectric element is used to feed the audio signal at start or stop, and when you turn on or turn off the timer. The supply voltage of + 5V is provided by M / s LM7805 voltage regulator. Power schemes carried out by a 9V power supply.

On the concept of the conclusions of 15 and 16, the LCD display shows "in the air". These findings are used only on the LCD, which provides for the display light. If your LCD supports backlighting, connect these terminals to the power supply.

Now, see how it works. For example, you want to include any device through a timer relay, after 2 minutes. Then, after the 220V timer switch is switched on, it must remain on for the next 20 minutes. In this case, the off time is set to 00:02 and at 00:20 on time. When the timer starts, the unit will be turned on after 2 minutes, and will remain on for 20 minutes. After that, the device turns off.

How to Choose the Best Metal Drill to Drill and Other Tools

Those who perform construction and installation work, the drill will be the best assistant. Inserted in a drill or other machine tools, it is accurate drill hole or tighten the screws.

In total, there are 4 types of drills for metal:

• Spiral - versatile, suitable for any kind of holes;
• Tapered - characterized by a smooth conical shape, suitable for holes of any diameter. They need constant supervision of the master;
• Stepped - also conical, but do hole drilling process a certain diameter easier due to the presence of stages of different sizes;
• Crown (circular cutter) - for holes from 12 to 150 mm, the laminates. Characterized by low power cutting roughness give high performance, which is impossible to achieve other types of drills.

What material is the best?

To use the drill in everyday life is better to choose one drill for metal with different densities. Selecting a tool for working with aluminum and steel is guided by the price. In search of quality tools, refer to the products of famous brands. They are made of solid steel and are solid-rolled. BTW, you can select the wide drill bit or drill bit collet at Banggood for high quality and reasonable prices.

Most drills are characterized by high quality marking of the USSR.

• HSS-R and HSS-G - suitable for use with cast alloy, carbon steel strength up to 900 N / mm2, aluminum, nickel silver, graphite, bronze or brass alloy, and iron;
• HSS-G Co 5 - for metal strength up to 1110 N / mm2, suitable for drilling stainless steel, carbon steel, alloy, not heat-resistant, heat-resistant steel;
• HSS-GTiAN / TiN - drills with titanium-nitride-coated aluminum, are suitable for use with cast iron, brass, nickel silver and bronze, cast steel.

Also, there are drills from cobalt (one of the most expensive and durable types of drills are suitable for drilling hard metals) and solid metal alloy (suitable for metal of great thickness have unilateral acute angle sharpening).

How to Install a Water Pump

In places there is no central water supply wells are drilled and set the pump (e.g. a high pressure water pump). The most common method of obtaining water, which does not differ from the use of conventional water supply system, is to install a vacuum pump station storage tank, which is mounted to the pipe, valve, and connect the Titans, showers, washing machines, dishwashers, etc. Pumping stations need to properly mount and install. This can be left to professionals or to make installation yourself, observing certain rules.

The 12V high pressure water pump should be installed as close as possible to the water source, that is, to the well. The room for the station setup must be dry and warm. Install the equipment in places with negative temperature values ​​are strictly prohibited. If the room is high humidity, a box with the contacts will get wet, leading to failure of all unit functions. Securely fasten the pump with the help of screwing the legs to a rigid, stable surface. At work there is a strong vibration, and if you do not perform properly secured, the pump will move.

Pipes need to connect reliable, for example made of metal. Through the rubber hoses run pump station impossible. The diameter of the tubes must correspond to the diameter of the pipe. Installation is done by installing a check valve on the well, it is securely attached to the tube pump station and from the receiving valve is mounted the entire system of water pipes. To tap into the system did not have air pockets, lining of pipes have to do with the rise in the direction of the station. The degree of recovery must not be less than 10-20 cm.

Connecting pump station is carried through a separate outlet with ground and safety guns that will protect against short circuit and, as a consequence, against breakage. Unscrew the cap on the tank, fill with water, screw the lid, turn off the tap and only then start the pump. This will release the air from the system, which is formed during assembly.

VR-Glasses Helping Nearly Blind Man to See Clearly

As is known, the VR is amazing technology, the use of which extends far beyond the area of ​​video games. For example, virtual reality has found extensive use in medicine: it can be used as an analgesic, to train military medics, reducing stress levels and even accelerate muscle recovery after paralysis.

As it turned out, the VR-technology capabilities can help another group of people - partially sighted with retinitis pigmentosa, because of which patients become almost blind. This is a fairly common disease: in the United States, for example, patients with degenerative eye disease that more than 100 million and they cannot practically visible.

But recently the Briton Jamie Soar suffering from retinitis pigmentosa, and diplopia (he constantly sees double) found for themselves out (though not completely healed) from its unpleasant situation - began his salvation VR-technology. As Jamie said in an interview with the Upload the VR , he almost did not see, and even sitting at a computer in the glasses he had to move up a person very close to the monitor, so that at least something to consider. He has long been realized that the solution to his problem has something to do with the technology of creating 3D-image: it had previously tried to watch 3D-movies, but they did not work. In general nothing worked, including surgical treatment, until he tried Vive HTC.

By happy coincidence, the virtual reality goggles (e.g. VR SHINECON) were great compensator his disease: although created by the VR-headset illusion of depth images, the screen is very close to the eyes, so that even with such a disease, like Jamie, the user is still perfectly visible. Moreover, the system will create a picture in the HTC Vive, essentially reducible to the intersection of two different images to each eye into a single, somehow miraculously Soare allows one to see a clear picture, not just a few horrifically blurry.

BTW, you can select the virtual reality goggles at Banggood. Besides, you can easily get other electrical accessories (e.g. double cigarette lighter) there with high quality and reasonable prices.
