The firmware. I based it on a couple of ready made sketches, but I had to modify almost everything for my own needs. At the moment the module can: show output level indication, display date, time, output stage heatsink temperature, switch inputs, turn on overheat protection (some functions are controlled by remote).

How to make a WiFi antenna with your own hands – a detailed manual with pictures
Sometimes the power of the existing router may not be enough and the laptop will be slow to catch the signal, and it is expensive to buy a new one. In this case, you can make a WiFi antenna of your own hands, and thereby strengthen the signal. Most often such a need arises when you need to transmit a signal over a long distance, or there are too many obstacles between two points. Homemade antennas can be made even from improvised means and some of the instructions we give below.
There are two basic types of antennas for WiFi routers: outdoor and indoor. Outdoor routers tend to be larger. There are also special mounts on their housings, which allow you to fix the device on a surface or support. Outdoor models are used to transmit a signal from one point to another over long distances. For uninterrupted communication, there must be no obstacles between these points.
Devices for indoor use (apartments, private houses, offices) are less powerful and have smaller dimensions. Some models have mounts with which they can be fixed on the wall.
Variations of WiFi-antennas with their own hands
Double bikvadrat
As you can see, the double biquadrate is easy to make. It does not require much time and expensive materials. Although you need to very carefully follow the dimensions given in the instructions. Nevertheless, the biquadrate is capable of quality transmission of an amplified and omni-directional signal and ensures stable operation of the network.
Powerful WiFi antenna gun
In order to get a powerful antenna-gun, capable of transmitting a directional signal at 10 km, it is necessary to strictly follow the instructions, because the slightest deviation can severely degrade the characteristics of the finished antenna. Each step should be done as precisely as possible. The procedure is as follows:
- The first thing to do is to cut out circles for the antenna. We mark the centers of the diameters of the circles on the metal sheet, and then drill them. To ensure greater accuracy, you should first drill the center with a thinner drill bit. The hole should be slightly wider than the stud. After using a compass you need to draw circles on a metal sheet. It is first necessary to cut out a square, and after that carefully cut off the edges to get a marked circle.
- Next, we take a long stud, and cut off all the excess along the length of the antenna, taking into account the width of the nut. The details look as follows.
- It is easy enough to assemble the antenna. It is recommended to use a metal ruler when assembling as it is more accurate than a plastic one. The outermost 2 disks should have holes in them so you can plug in the cable. The cable connector itself can be made from an old antenna (router or Wi-Fi adapter).
- Now you need to tin the disks with copper. Through the previously made hole in the last circle, pass the cable and solder between the winding and the disk.
- Put the middle strand through the hole in the second disk and solder.
- Wireless Wi-Fi adapter screwed to the output of the connector and glued it to the bracket.
- The antenna is ready.
A powerful, homemade Wi-Fi antenna for receiving signals from remote open networks
It is quite common to find open Wi-Fi networks with good download speeds. However, they have a limited range, which does not allow you to constantly count on free internet. You can solve this situation by using a powerful antenna capable of capturing Wi-Fi several kilometers away from its source.
The necessary materials:
To assemble the antenna, you need to cut round plates from canning lids. Before doing this, you need to find the center on them and drill a hole of 8 mm in it for further threading of the plates on the stud.
You can determine the center with an ordinary office ruler. It is placed on the lid so that its corners are on the line of the circle. A felt-tip pen is used to draw two parallel lines along the edge of the ruler, and then the same marks are made, but with an offset of 90 degrees. As a consequence, the lid will get a grid with a square in the middle. Drawing a diagonal in it you can mark the center for drilling. It is most convenient to mark one cover and drill them all together in a pile, which will greatly speed up the process.
Next it is necessary to trim the covers to the diameter corresponding to the scheme of the antenna. To do this, the first cover is left unchanged, the second is cut under 68 mm, the third under 50 mm, and another 17 pieces under 40 mm.
It is very important to make the trimming straight, so a marking is made first. The circumference is drawn with a compass or with a paper clip.
Long Range Wi-Fi Antenna
Such a device will greatly enhance signal reception and transmission. If conventional antennas deliver signals to a maximum radius of 5 kilometers, the long-range transmitter will increase this value to 10 km.
- Prepare the fiberglass which will be used as a reflector;
- cut it into a rectangle of 10 x 14 cm;
- Drill holes in the middle of the plate for the cable;
- Using copper wire, construct the antenna itself, it is two squares connected to each other;
- Solder the cable to the copper squares;
- Attach the antenna to the reflector.
Scheme of the device Wi-Fi antenna is quite simple: a reflector, the antenna itself, made of copper wire and cable. Such a design, despite its simplicity, is able to deliver a signal over a long distance.
Antenna up to 50 kilometers
This device is not difficult to make your own hands, following the principle described above. The main difference is the large size of the reflector, approximately 35 by 45 centimeters.
Vibrators made of fiberglass are installed on it.
In other points, the scheme of making a wi-fi antenna capable of receiving and delivering signals at a distance of 50 kilometers, will be similar to the step by step description of the manufacture of long-range antenna.
If you need to strengthen the received Wi-Fi signal, do not rush to visit stores with expensive routers and add-ons. It is possible to improve the performance of your existing antenna with additional reflectors and gratings.
Try making a powerful transmitter with your own hands, it will be much more efficient and clearer to receive and deliver signals even over long distances. The above instructions will help you make a powerful long-range Wi-Fi antenna.
Ubiquiti Spain LBE-M5-23
This is an ultra-light, long-range device at an inexpensive price. This antenna provides 23 dBi gain for long-range communications and uses a directional antenna with an improved beam pattern for interference immunity. With absolute freedom of alignment characteristic on three axes. Assembles in seconds, requires no additional tools other than those needed to hold it in place.
Wonect N400 WiFi antenna
This Wi-Fi antenna provides the longest possible range in almost any environment. Wireless transmission can reach up to 2,000 meters, which is far superior to similar products from other manufacturers. That's why we always say this is a great Wi-Fi antenna with the maximum range.
Hi-Fi amplifier based on the MX50SE kit from Aliexpress
When you need a normal sound and, at the same time, you are an engineer, then you want to save money and get an acceptable result by making an amplifier yourself from what you have available and Chinese components.
– A handful of 4700 µF x 40V Vishay axial capacitors;
All that was soldered out from old dismantled industrial equipment before sending it to the scrap yard. So why not give it a second life? 
– LJM's MX50SE amplifier termination kit (a proven, popular amplifier);
– Preamp board with Ayima toneblock;
The Kompak case was stripped from plastic to metal. Sawed the sides from scrap laminate. On the face and butt were sawed out unnecessary and protruding parts. The butt was covered with two pieces of galvanized sheet metal with holes drilled in them for connectors. The muzzle was cut out of material that I don't know what to call it – plastic on the inside and film-covered aluminum on the outside. The film on the back side can be easily peeled off with sandpaper and brushed to an acceptable appearance. The holes for the knobs, buttons and display were cut out.
Slowly the termination boards, protection unit, power supply, transformer boards, input selector boards were assembled.
Shame
Ty. I can suggest the following ways to deal with "achotakova" neighbors asking for WiFi access.
"Secret Agent."
When you buy a router, change the SSID (wifi network name) and disable SSID broadcasting. If the neighbors ask – no woofhoys, they are harmful, cancer, we are monitored through them, as proof pull a tinfoil cap out of your breast pocket.
"Intrigant."
Rename the router to kvartira_XX, where XX is the apartment number of the oldest and meanest babka, a non-existent apartment or an apartment in the next doorway. If there is a store, hairdresser's or something like that on the first floor, use the name of the point with "clarification" – Produkty-office or Afrodita-podval. If the house has an elevator – lift-camera. It's best if there are no cameras in the elevator. Or is there?
"The Inquisitor.
Many modern routers support the guest network function. Turn it on, limit speed to 1Mb/sec or lower, password of course, give the password to such neighbors, preferably all, but a big secret. Hide the main network (see "Secret agent"). Periodically we give in to the neighbors, say, the Internet in general is disgusting, to complain about the fact that not enough money for a tariff with a higher speed.
"Sophisticated Intriguer."
Combine the Intriguer and the Inquisitor. Rename the working network as suggested in "Intrigant", change the password, and use it. The guest network is called by the same name as the work network, cut the speed and then as in "The Inquisitor".
"Housekeeper."
Some routers support scheduled WiFi turning on and off. You can connect such a cable to your working router, set WiFi to turn on and off at 2-minute intervals, and "hide" your network (see "Secret Agent"). If you have an old unnecessary router without a schedule function, you can connect it to the outlet through a time relay or a "smart" programmable socket.
