Probably many would like to add something new to their car, today I will tell you how to do it without any special costs and technical changes in the design of the car. The device that I want to introduce you today is not a large scheme for adjusting the start and stop of the load, in our case, lighting, interior lighting, dashboard lighting, etc.
Having decided to keep up with the times, and to save my money in the future, I decided to make some useful innovation. More precisely, to remodel lamps with fluorescent lamps into lamps with LED lamps. The service life is high, the savings are great, and the cost is not much more expensive. Of course, you can buy, but believe me, it's expensive to buy, compared with the version made.
The theme of alteration or modernization of failed fluorescent (energy-saving) lamps into LEDs has been raised repeatedly. Forgive me the authors of these articles, but most of the proposed options are ineffective and certainly not aesthetic. The reason for this is the difficulty with the element base and accessories, as well as our mentality when we try to mold candy from ... But thanks to the Koreans who released the wonderful Seoul Semiconductors Acrich2 LED module last year, which connects to 220 V AC without an additional power source.
Many thanks to the manufacturers of modern energy-saving lamps. The quality of their products constantly makes them move their brains and pushes for new technical solutions. So this time, we will consider the topic of altering a failed energy-saving lamp into an LED. Today we will take a more traditional path using the driver for the LED, but ... The most interesting part of the alteration is the LED itself.
The simplest jobs related to electricity are difficult to do without measuring tools. It is not necessary to measure the parameters of the electric circuit with a tester, in many cases it is more convenient to do with a universal probe that infects the presence of these parameters by means of light signals. This is quite enough for convenient and safe work with electrical circuits.
How to make an automatic hood? “It's not at all as difficult as it might seem.” There are very different options, but I settled on one such as a thermal relay. It will work like this: someone will cook something with a gas or electric stove, then naturally heat and heat will come from fire and food.
To build an electric motor you need only a few things. 1. Battery (or any other small source of energy) 2. A coil of wire 3. An electrical tape 4. 2 pins or paper clips (you can use other objects or create holders from a wire, for example, the choice is yours) 5. Magnet.
We remake an ordinary light bulb into an LED. The photo shows examples of manufactured holders for LEDs. Using this technology, you can make a holder of any shape for LEDs of various sizes and with any number of them. For work it will be required: 1. Reflector; 2. LEDs; 3. Superglue; four.
On the Internet there were only circuits on these microcircuits, but the assembled amplifier was never found. Operating mode AB, Supply voltage 10 ... 32 Volts, Stereo configuration, Operating temperature 0 ... 70 degrees. Such microcircuits can be found in modern TVs and, probably, at least someone managed to pull out such a thing.
About six months ago I bought a car. I will not describe all the modernizations made to improve it; I will focus only on one. This is a 12-220V inverter for powering consumer electronics from the car's on-board network. Of course, one could buy it in a store for $ 25-30, but their power was embarrassing. To power even a laptop, a current with 0.5-1 amperes, which most automobile inverters give out, is clearly not enough.
ELECTRIC POWER FOR FREE (DO NOT COLLECT THE COUNTER) For lighting, powering the TV, refrigerator, other electrical appliances. No need to "improve the electric meter, connect to a neighbor, replace existing electrical appliances - you don’t need to do anything! NEW PRINCIPLE OF POWER SUPPLY OF ELECTRICAL APPLIANCES IN HOME, In the apartment, electrical appliances are connected to the network in parallel, since U = 220 V and is constant in value, then each new inclusion increases current consumption: We offer you a new invention.
On one of the amateur radio sites I saw a circuit for charging portable Ni-Mn and Ni-Cd batteries with an operating voltage of 1.2-1.4 V from a USB port. Using this device, you can charge portable rechargeable batteries with a current of approximately 100 mA. The scheme is simple. To assemble it is not difficult even for a novice radio amateur.
Electrophore car assembled from compact disks and 2 coolers. It produces about 20,000 volts, which is limited by the distance of the gaps between the plates of the capacitors of the disk. Photos and assembly description. Easy repeatable device. I took 2 CD-R discs (it’s easy to easily clean the layer of the storage medium from them) and cleaned them of the coating, after which they degreased with alcohol.
Every motorist sooner or later has problems with the battery. I did not escape this fate. After 10 minutes of unsuccessful attempts to start his car, he decided that it was necessary to purchase or make a charger himself. In the evening, having made an audit in the garage and finding there a suitable transformer, I decided to do the charging myself.
This transmitter showed good quality of the transmitted music, so I recommend starting with this scheme. As practice has shown, an assembled generator on a single transistor cannot, stand in one place, without an additional cascade, the frequency constantly goes out when a hand is brought up or applies voltage.
An ultrasonic washing machine is intended for washing clothes with the help of sound vibrations created in the washing solution, the frequency of which is close to ultrasonic. The features of the trigger are that when washing there is no mechanical friction of the laundry, the laundry after washing the trigger is completely disinfected, the power consumption of the device is not more than 15 watts.
For effective drying of shoes, a constant influx of warmer, and therefore less humid air than the surrounding air is necessary. According to this principle, the proposed dryer works, the scheme of which is shown in Fig. 1. As heating elements, resistors R1-R12 are used. A fan blows them, and heated air enters the shoes through the air ducts.
We need the following components: one LTR-4206E phototransistor one lithium CR2032 battery (3 V) 2N3904 transistor 1 K resistor Photos of these components: Progress: First, take the transistor and resistor and solder them as shown in the figure: Next, solder the phototransistor to this design : Next, we attach the LED: And then the power source: And now we look at what we got: This light will turn on when it becomes dark
The following practice shows that lying and rejection of guilt by criminals are associated with various physiological phenomena. Before that, this is an increase in the pressure of the blood, a change in the moisture of the skin, as well as inadequate swallowing of saliva, as well as little hypodermia. These phenomena were used by physiologists and psychologists to develop a polygraph or a “lie detector”.
Summer comes, and with it mosquitoes and all sorts of other midges appear. Everyone knows how mosquitoes annoy, especially at night. The proposed device allows you to protect yourself from all insects, and if you increase the frequency of the generator to ultrasound, then from dog barking. The device diagram is shown in Fig. 1, and the printed circuit board - in Fig.
