Often at the entrances of houses, transport stops and just on the fence you can see notices that a purchase is taking place different equipment. We are talking mainly about broken things or those that are morally obsolete. The population thus has the opportunity to get rid of unnecessary garbage. For a businessman, buying up old televisions that have fallen into disrepair is a good opportunity to make money.
You can deal with TVs bought with little money in different ways. Most often they are dismantled for spare parts. The resulting parts are sold to various production facilities where they are accepted. New technologies today make it possible to reuse spare parts. This makes it possible for an entrepreneur to receive a stable income. Often buying household appliances has the format home business. Investments in it are minimal, and practically no knowledge is required. To develop your business you will need mobile communications, the Internet and your own residential or non-residential space. To this you need to add ingenuity, imagination and a great desire to receive satisfaction from your work.
HOW TO MAKE MONEY FROM OLD EQUIPMENT?
Most ordinary people do not even realize that they have unique and rare things stored in their apartment. These are old televisions, radios, walkie-talkies. Any old equipment is valuable today. If you don’t have such items in your house, then your relatives probably have them. Grandfathers and grandmothers are often happy to get rid of those things that take up space in the house and have not been useful for a long time. How many of them are still in the houses of our friends and relatives!
Now the question arises: we organized the reception of old Soviet televisions, but what is their value? The fact is that the manufacturing technology of many parts of old equipment involved the addition of precious metals and copper. Silver, gold and even platinum were added to the boards. A completely fair question arises: how many of these metals were there before, if they are even in technology? Previously, the device simply could not work without them. These precious metals are the goal of our business. It is “gold” that makes accepting old products profitable and cost-effective.
In addition to precious materials, old TVs contain a lot of non-ferrous metals. These are pieces of copper and aluminum. You can select them from the details mechanically. Gold and silver, for example, are only extracted using chemical reactions. You can judge how much aluminum or copper is in a TV based on the specific model. As for copper, it was used as winding in transformers. Typically, 500-800 grams of copper can be extracted from one TV, and sometimes even more than 2 kg. 1 kg of it costs 145 rubles on the market, and aluminum is valued at 50 rubles.
Taking Soviet technology and extracting valuable materials and copper from its parts forms the basis of our home business. Even if the entrepreneur does not have the knowledge to isolate metals, the boards can be sold to people who know a lot about radio engineering. Even under such conditions, the purchase will be profitable.
Below are the minimum prices for some TV radio components. Here's how much it might cost:
Buying old receivers and televisions is a business. It requires a commercial approach and some organization. In addition to information on poles, you can advertise that old equipment is being purchased in newspapers and on the Internet. Advertising and reception costs may be minimal. You will need some funds for gasoline and a car. It must be roomy. In order to save money, it is better to plan your route in such a way as to accept equipment from several addresses at once. Space for equipment can be allocated in own apartment. It's better if it is a private house. Then the reception can even be organized on your own premises. It is necessary to calculate the costs of selling copper and precious metals.
Buying old radio devices will be profitable when the entrepreneur learns to accurately set prices for them. How much you can earn depends not only on the state of the equipment, but also on your bargaining ability. As such prices or market prices There are no televisions for reception. Their cost is always determined approximately. The owner's benefit is the last thing that is taken into account when a purchase takes place. A businessman must be sure that he will make money on the item he purchases, on the sale of copper and metals from it. The cost of an old TV can be several dollars or even several hundred conventional units. Japanese TVs produced several decades ago are highly valued. This technique has been and remains the most reliable.
Hello to all DIYers, as usual, every novice radio amateur has an idea to do something, but the first thing that usually comes to mind is to assemble an amplifier that will be easy to assemble and does not require financial costs. That is why I decided to build an amplifier, the main “heart” of which can be extracted from an unnecessary or old TV; I will tell you how to make it in this article.
To assemble a sound amplifier, we need to prepare everything necessary materials, This:
TV, unnecessary or just old, keep in mind that you will not find such an amplifier on TVs made in the USSR.
Soldering iron and everything needed to use it, stand, solder and flux.
The wires will fit perfectly from the computer power supply.
A plug for tulips, these can be found in a radio, DVD player or music center.
A clamp for the wires through which the amplifier-amplified sound will flow is also found in most music systems.
Cooling radiator, I removed it from an old vinyl player.
The power supply from the laptop, the internals will not be needed, but only the case.
Pliers.
Two-pin plug, the diameter of the contact fits into the block from the PC.
A utility knife for making holes.
Once all the details are ready and you have definitely decided that the moment has come when you can make a simple amplifier, you can begin step by step assembly.
Step one. As usual, the TV is made of plastic; remove it to get to the board. Attention, before disassembling, remove the plug from the socket, it’s not for nothing that the TV says high voltage. After the cover is removed, you can examine the board; there is a radiator on it, which is usually made in the form of sheet aluminum. You need to cut the board with metal scissors or using pliers, leave more than 10 cm around the chip, since the board should remain working.
Step two. In order to make a sound amplifier from the “insides” of a TV, you need to find information on the Internet about the microcircuit, the markings of which are written on it in white letters with a set of numbers, in in this case This is a TDA 2611 microcircuit, information about it is in the datasheet and the connection diagram, see in the photo.
It is according to the scheme that we will give the microcircuit a second life.
Further assembly will take place using the circuit shown in the picture. Using a soldering iron, we solder a pre-tinned red wire to the 1st leg of the microcircuit, the count goes to the right, this wire is the plus of the power supply, for the minus we take the black wire, which we solder to the 6th leg, these two wires are attached to the plug.
We've sorted out the power supply, now we need to make a sound input, which can be supplied from any player or phone using a jack plug adapter on one side and a pair of tulips on the other. We solder the inputs for these tulips to the 7th leg through a resistor attached to the board at the input and the 6th leg.
We make the sound output at the clamps, the wires of which are connected to the track of the 2nd leg of the microcircuit coming after the 220 µF capacitor, the second contact goes, as in most cases, to the minuses.
Part of the amplifier electronics is ready, now we need a good, noble case with cooling. Without thinking twice, I opted for a power supply for charging the laptop; it seemed to me that the case made from it would be good. Well, let's get started. First, let’s unpack its contents and use stationery knife Let's cut holes for tulips and power on one side and on the other for sound output.
All plugs are attached using hot-melt adhesive. Finally, you need to screw the amplifier chip onto the radiator and also secure it with hot-melt adhesive.
A pot-bellied tube TV has long been considered one of the obsolete “dinosaurs”, but in some places such a rarity is still preserved: for some it’s huddled in the far corner of a closet, for others it’s gathering dust in their dacha... But you can give it to him too new life and a new purpose - so don’t rush to send the old “box” to the landfill!
Aquarium
Perhaps one of the most popular and favorite ideas for using an old TV - remember the one created by Jake Harms? The only difference is that the designer used old computer monitors. The technology is simple: remove the metal insides from the TV and insert an aquarium of a suitable size. In this case, you can leave the back of the drawer free, or close it and use LED lighting.
Cat's house
Why spend money at a pet store when there is a great opportunity to adapt old TV? Having taken out the filling, cover the back of the box with plywood and add finishing touch- a pillow or fluffy blanket will allow your pet to settle down in all comfort.
Treasure Chest
“But these are just books,” some readers will be surprised. And the most savvy will only smile: of course, these are real treasures! So creative bookshelf It is a great incentive not to waste your time, and will help those people who dream of overcoming the widespread problem of our time.
Reason... to green the space
Look, all channels show ficuses, geraniums and violets! - And it’s not surprising: this funny flower bed was invented by Toronto residents. Although, on the other hand, the Canadians wanted to express a very important idea: technogenic civilization is still unable to defeat the power of living nature! Well, readers can start by greening at least one old box- for example, set up a terrarium with sand and stones for succulents.
Cozy armchair
Designer Phil Garner decided that there was always time to get rid of the old TV - it was better to arm yourself with carpentry tools and experiment! This is how this unusual-looking, but very positive and not boring chair turned out: we cut out the top cover, remove the filling and put a soft pillow or blanket in the free space.
Housing for a hamster
And any other small living creatures - lizards, etc. Having removed the excess, we install the aquarium inside. There is no need for a cover on the back - after all, your pet will need daylight. Well, the rest is up to you - add sawdust, a wheel, a mini-house, toys.
Vintage minibar
On the one hand, it looks luxurious (some masters even manage to add velvet curtains to the composition). On the other hand, drinking alcohol, and especially showing it off, is not the most good idea. You can offer a compromise: instead of bottles, you can keep delicious jars of jam here, and in the summer - a decanter of other cool drinks for guests.
What about the “filling”?
Try to dispose of the insides correctly - you cannot throw them directly into a landfill. Electronic waste causes irreparable damage environment because they contain a huge amount heavy metals- lead, tin, cadmium. All this either penetrates into the ground, groundwater and atmosphere. At the same time, according to GreenPeace representatives, we still do not have government programs for recycling such household appliances.
However, those who seek will always find! Firstly, on the Internet you can find contacts of companies offering their services for recycling old electronic waste. Secondly, you can contact state recycling companies industrial enterprises. And finally, suggest old equipment repair shops - by the way, an experienced radio amateur can make a welding machine, a Chizhevsky chandelier, a metal detector and a lot of other interesting things.

Nothing in this world lasts forever, and the life of gadgets is sometimes very fleeting. But if you love retro style and are frugal and resourceful by nature, then you can give them a second chance by transforming them into something useful and retro looking.
5. Turn an old mouse into a wireless one
Old mice aren't as comfortable or ergonomic as newer models, but they give you that comfortable feeling, like an old shirt that's so old that you sneak it around the house on the weekends when no one is looking, simply because you've had it for a long time and you like it. you are used to it :) If you are still using an old wired mouse, or have kept it as an old battle friend, then now is the time to convert it into a wireless Bluetooth mouse, simply replacing the insides of the old mouse with the insides of a new one.
Let’s say right away that this is a decision dictated solely by a feeling of nostalgia rather than by practical considerations. If your old mouse is too awkward to use on a weekly basis, you can use it to make a camera shutter.
4. Turn an analog TV into an information terminal
Most likely, you have already updated your entire fleet of televisions a long time ago, and the old CRT monitors are gathering dust in best case scenario, somewhere in the country. You can give an old TV a new life by turning it into a YBOX (a homemade information screen that shows the weather, for example).
An alternative use is a retro photo frame, which can be placed in the living room. To turn a TV into a photo frame, you need to remove the insides of the TV and replace them with the old sockets and power cord from the lamp, screw in a low power CFL lamp, insert a printed image on the screen, close it and turn on the “TV”.
Now you have a fun retro frame.
If you don't want to waste electricity, recycle your old monitor into a trash bin.
3. Make an aquarium out of an old TV or computer
A project from the “incredible but true” series marked “dangerous.” Do it at your own peril and risk. If you have an old TV, computer or other unnecessary equipment with plenty of space inside, you can turn it into an aquarium.
If you want to use Floppy drives for their intended purpose, you can put USB in them.
1. Making a VoIP phone from a rotary phone
If you're having a hard time saying goodbye to your old rotary phone, you can turn it into a fun computer headset for use with Google Voice, Skype, or any other VoIP solution.
If you have a few unwanted cordless phones (not really old ones), then you can make good walkie-talkie radios out of them.
I hope this collection of ideas for transforming old gadgets has inspired you. Following the links you will see visual guides on how to do this or that thing, on English language. All guides have good visualizations of each of the conversion stages.
Everyone once had old televisions, those big ones, tube ones, with a convex screen and in most cases black and white. Many of them have long been thrown into the trash or disassembled for spare parts, and some still have them stored somewhere in a barn. It would be nice if such a TV brought at least some benefit, and did not take up space and collect dust. In today's material, we will talk about several cool ideas, what can be made from an old TV. It will be interesting!
Aquarium
So, the first craft we will talk about is an aquarium from a TV. You shouldn’t be surprised or think that this is some kind of joke, no, everything is serious here. In addition, the aquarium is very popular among TV crafts. One has only to write in a search engine “what can be made from an old TV”, and immediately the first proposed option will be an aquarium.
What will need to be done to make everything work? Yes, in general, there is nothing particularly complicated here.
First you need to very carefully remove all the insides of the TV; they will no longer be needed. Ideally, only the body should remain. The back wall (lid) also needs to be removed.
The next step is to select a ready-made aquarium from the store that will fit inside the TV. For greater beauty, the aquarium can be covered with a film with a marine theme. This will make it look more interesting.
Now you need to unfasten the upper part of the body and make it either completely removable so that the fish can be fed, or attach loops to it to make it folding design. You also need to screw a lamp on the bottom of the lid, which will serve as a light source for the fish.
Actually, almost everything is ready. We place the aquarium inside the case, insert the frame in front that covered the screen, fill it with water, add the fish, lower the lid and connect the lamp. Voila!
Mini bar
The next thing you can make from an old TV is a minibar. Not everyone has their own little bar in their house or apartment for one simple reason - there is no space. However, if you have an old TV at hand, then this problem will quickly become solvable.
The procedure here is as follows:
- All the “internals” are pulled out and removed.
- If installed at the rear plastic cover, then it is recommended to remove it, and instead screw a piece of panel plywood or fiberboard to the body.
- For beauty, it is recommended to cover the inside walls of the future minibar with some kind of self-adhesive film. Also, some users prefer to make a small backlight from LED lamps inside the case.
- In general, the main work has been completed and at this stage, the mini-bar can begin to be filled. If you wish, you can improve this household item and make a front hinged lid that would cover containers with booze from prying eyes. In addition, some users devote a lot of time external decoration TV housing to get something very original and beautiful. But here a lot depends on desire and imagination.
House for a cat
What else can you make from an old TV? How about a house for your beloved pet? The tailed friend will be very happy with such a gift.
The house is quite simple to make. To begin with, all the “stuffing” and the TV picture tube are removed. Only the body should remain. The back wall, if made of plastic, is replaced with a fiberboard sheet.
Locker
A small and neat cabinet is what you can do with an old TV. This craft will not take up much space in the interior and will look very harmonious, giving some zest.
The cabinet is made according to a principle similar to previous crafts. First, the “insides” are removed, then, if necessary, the back wall is changed. Next stage- shelves are installed inside the cabinet so that small items, books or anything else can be placed on them. You can, of course, do without shelves, anyone has any wishes.
Once the body is ready, you can start decorating. Here, too, a lot depends on imagination and wishes. Some people simply paint everything the same color, some make the cabinet multi-colored, others completely cover the walls with film and wallpaper.
The final stage is to place the cabinet where it will stand and fill it.
Flower bed
Continuing the topic of “what can be done with an old tube TV,” one cannot help but note such a useful feature as a flower bed. Yes, an old TV may well become a decoration for a garden or flower bed.
You can make a flowerbed different ways. The simplest one is to take out all the “stuffing” from the TV, put the case on the back wall, pour soil inside the box and sow flower seeds there. You can also immediately transplant the flower there and not wait for the seeds to germinate.
Another way to make a flower bed, which is slightly different from the previous one. The TV is also cleaned of all “internals”, the back wall is removed, and it is painted in some bright color, after which soil is poured inside and flowers are planted there. This flowerbed will look especially beautiful with plants that grow strongly and branch profusely. Also, such a flower bed can be hung and get even more interesting result.
Nightstand
The next thing you can make from an old TV with your own hands is a bedside table. This one is simple, but at the same time useful item interior design is done simply and without much effort.
The principle here is somewhat similar to a locker. First, the body is prepared, the partitions are set up, you can even try to make a small drawer. After this, the bedside table is painted in the desired color and, in principle, you can use it.
However, if you go to a hardware store and buy several different foam moldings there, then from an ordinary simple bedside table you can completely make an interior item in classic style.
Photography lamp
Well, and the last craft. Here we are not talking about a simple tube TV, but about an old device with a flat but broken screen. Surely someone has these at home too. Many people think that if a screen breaks, they should just throw it away, but in vain. Now we will tell you what can be done from an old TV from Samsung, Sony, LG and other brands with a broken flat screen.
We'll talk about a photography lamp. Probably everyone has seen such lamps in a photo studio.
Here's what to do:
- We disassemble the TV.
- We disconnect the broken screen.
- We put the TV back together, plug it into a power outlet and enjoy the finished craft. If desired, it will be possible to construct some kind of mount so that the “lamp” can be installed as needed.
Watch a helpful video that shows how this lamp is made.
