Before you start making a tree from plywood, you must first prepare a sketch, which will then be used to make a paper model and a template for cutting out the necessary parts. You can create your own drawings.

For beginning craftsmen who plan to make such a craft for the first time, experts recommend choosing simple models. They will be much easier to cut and assemble.

Beginners can quickly make a drawing and sketch for plywood wood using a special application using the following diagram:

• first you need to select the picture you like and transfer it to the working window of the program;
• then you should select the scaling section, taking into account the dimensions of the existing sheet of plywood;
• the finished drawing is divided into fragments, each of which is printed in turn;
• The preparation of the template is completed by gluing all the fragments into one sheet, after which the contour is carefully cut;
• Next, the template is applied to a sheet of plywood and outlined with a simple pencil.

If you have all the details, the question of how to make such a lock with your own hands is not difficult.

• A set of radio components with a board is purchased.
• An automobile electric drive is installed on a relay as a motor.
• The latching device is selected in accordance with the existing lock.
• A board with a relay is installed on the door frame, to which electrical wiring is connected.
• For the housing, you can take a plastic cover with holes drilled in it for installation.
• Holes are drilled in the U-shaped aluminum profile into which buttons are inserted. The diameter should be equal to the button on the cambric. This is important for high-quality signal operation, so that there is accurate centering.
• Wires are soldered to the buttons and LEDs, and the entire structure is filled with epoxy resin.
• The panel is attached to the door using screws.
• To ensure uninterruptible power supply, a UPS is connected.

If you need a drawer

In general, a wooden box with a drawer is made in the same way as the classic version, but there are a number of features.

A simple rectangular shape of the lid and bottom will spoil the appearance of the product. It is better to make the long sides of these elements wavy using an electric router. In addition, by choosing this option, the lid and bottom are not placed inside the body, but left outside.

The walls are made of different heights. In particular, the back part and ends are made of the same height and glued together. For the front wall, cut out a die half as wide as the back part. This element is not recessed between the ends, but is installed overlapping and fixed with glue.

The box consists of two parts: the box, which fits freely between the walls, and the front part, which is similar in size to the top die. The elements are also mounted on wood glue.

A partition is installed between the upper and lower parts, which will serve as the bottom of the upper compartment of the box. Inside the retractable and stationary drawers, you can make partitions from thin plywood, delimiting the internal space into several compartments. The lid is installed on decorative hinges, the wood is covered with several layers of furniture varnish.

Electromechanical lock with Arduino

I, like most people who have one, associate Cottage with the words: relaxation, barbecue, comfort and other pleasant movements for the spirit and body, but there is also a downside: gardening, digging, repairs, construction, etc.

For 10 years, my family and I have been trying to improve and create maximum comfort in our dacha. We build, repair, etc. House, barn, bathhouse…..and finally it came to the street fence, gate and gate. Do this according to conscience, budget and convenience.

After discussing some details, it was decided that the gate should be automatic and the gate should have some of the properties of an access control system. With the gate, the issue was resolved by purchasing an automation kit (drive, rack, remote control, etc.), but with the gate it was necessary to solve some problems, more about them below.

The tasks were the following:

1. The lock had to work in conjunction with a previously installed video intercom (open the gate without leaving the house)
2. Be able to open the door with a regular key and without a key from the street and yard.
3. Will fit within the remaining budget up to 5000 rubles.

Searches in RuNet presented the following price range from 7000 to infinity. Purchasing a ready-made solution was no longer necessary and an alternative with wide possibilities was conceived, namely to cut down the door yourself!

After some calculations and calculations, it was decided to buy an electromechanical lock for about 2000 rubles, a waterproof keyboard for 350 rubles, and a microcontroller that will drive here. Since there were several Arduino nano boards, relays and loose parts and some wires, the difference between the cost of the finished kit was more than 4000 rubles. For me, it’s a great bonus for your wallet and self-development.

Well, now from words to action:

After purchasing all the necessary components, I began sawing.

A panel (grid) made of plexiglass, cut for a box of chocolates and a smile by office neighbors. But the smallest cutter turned out to be a little fatter, so I had to work with a needle file.

Well, it’s the weekend, I went to the dacha.

To open an electromechanical lock, you need 12 V. The power supply supplying the MK was 5 V, the decision was to install a boost dc-dc converter from the Middle Kingdom for the castle. I connected everything and started checking it, it works, but when voltage was applied to the lock solenoid, the Dunya rebooted, causing a short to the power supply. Further more, after connecting the calling panel from the video intercom to the lock, when you pressed the button to open the door, nothing happened, a small current to the lock. Running new wires is not an option; they were already concreted at the exit from the house. I decided to add another relay for the panel and install an additional 12 V power supply. for the castle. After parsing/assembling, everything worked, the MK stopped rebooting. I hid the whole thing in a moisture-proof junction box, hid the wires, glue, silicone and ready!

The wire for the keyboard is a regular wire 8.

The code itself is attached.

• for needles, threads. Such wooden boxes usually have several compartments where you can store sewing supplies. The case is often complemented by a carrying handle.

Briefly about the main thing

The prospect of doing without keys looks tempting, so more and more owners prefer combination locks. These devices differ in shutter mechanisms and installation methods, and according to the locking method they are divided into mechanical, electromechanical and electronic.

When choosing an outdoor device, pay attention to its degree of protection against burglary and negative weather factors; Comfort of use and availability of certificates are important. The greatest capabilities are provided by electronic models that can be integrated into a home security system and work through remote access.

How to put a lock

An interesting solution is a mortise lock, which will be opened with a small key, but such work is difficult to do even for an experienced specialist. Therefore, it is better to limit yourself to a padlock or a decorative hook.

To install a padlock, loops are placed in the central part of the side wall and lid, which are screwed with small screws. The location of the hinges must be calculated in advance: even a slight displacement will break the symmetry, and the box will lose its attractiveness.

Combination lock on microcircuits

The disadvantage of the diagram in Figure 1 is that the code buttons must be pressed simultaneously. A more convenient option is to press the buttons sequentially according to the sequence of numbers in the code number.

Such a circuit is shown in Figure 2. The circuit is built on two microcircuits K561TR2 and K561LA7. In addition to sequential code dialing, there is also a sound indication of pressing each button.

The power-up keyboard consists of ten buttons S0-S9 (for convenience, the buttons are numbered with the same numbers as they are labeled). The code consists of four numbers, the buttons of which must be pressed sequentially.

In this case, code: 0478, respectively, you must first press the S0 button, then S4, then S7 and finish by pressing S8. Only in this order. Naturally, the code may be different, it all depends on the wiring of the buttons.

Rice. 2. Schematic diagram of a combination lock based on K561TR2 and K561LA7 microcircuits.

The K561TP2 microcircuit has such a feature that its RS triggers have priority over the “S” inputs. That is, while there is a one at the input “S”, the state of the flip-flop “1”, and it does not change when one is applied to its input “R”. All four flip-flops of the microcircuit are connected so that the output of one flip-flop is connected to the “S” input of the other.

As a result, this entire system of four RS flip-flops can be set to zero at output D1.4 only by sequentially setting to zero states, first D1.1, then D1.2, then D1.3 and only after that, D1.4 . And nothing else.

To set the triggers to zero states, you need to apply a logical one to the “R” input. Here this is done with four buttons, selected by numbers according to the code. In this case, the code is 0478, respectively, these are the buttons SO, S4, S7, S8.

These buttons are turned on so that when they are pressed, a logical one is sent to the “R” input of the corresponding trigger. After sequentially pressing the code buttons, a logical zero appears at output D1.4. It is inverted by element D1.4 and the control electrode of thyristor VS1 receives the opening current through resistor R9. The thyristor opens and relay K1 turns on the load or equipment with its contacts.

In order to set one at output D1.4, you need to apply one to input “S” of D1.1. In this case, all four triggers of the D1 chip will be sequentially set to the single state.

All buttons whose numbers do not correspond to the code are connected in parallel and connected to pin 14 of D1.1. When any of them is pressed, all triggers return to their original single state.

For audible signaling of button presses, a multivibrator is used on logic elements D1.1 and D1.2. When you press any of the buttons, one of the diodes VD1-VD5 opens and supplies a logical one voltage to pin 2 of D1.1. At the same time, the multivibrator starts and the piezoelectric sound emitter BF1 sounds.

The sound lasts as long as the button is pressed.

To automatically reset the trigger circuit after turning on relay K1, use a circuit using capacitor C1, resistor R7 and logic element D1.3.

The load or equipment is turned off using the S10 button. In this case, the power circuit opens and the thyristor closes; after S10 is released, it remains closed until the next correct code is dialed.

Original flower bed made of plywood

Plywood is widely used not only for creating home crafts. This material is very successfully used for the manufacture of garden figures, decorations, and flower beds.

• Depending on the wishes of the owner, these can be hanging flower pots, beautiful carts for flower pots, or vertical flower beds.
• For work, choose a more durable material, the thickness of which is more than 3 cm. It is also important to pay attention to the condition of the plywood, for example, the absence of cracks, chips, defects, and signs of delamination of the layer.

In independent work, detailed attention is paid to impregnating the finished product with a mixture of drying oil, melted wax and turpentine, which will protect the product from moisture and seasonal rains.

DIY plywood crafts: diagrams, templates for flat and three-dimensional products

1. First of all, you should choose a sketch. Today, black and white portraits or shadow images are very popular.
2. The sketch is drawn on the back side of the plywood using a pencil.
3. The sheet of material is firmly fixed, for example, using clamps.
4. The edges under the clamps should be wrapped with a soft rag or sponge so that the surface of the plywood does not crumble under strong pressure.
5. The details are cut out according to the applied template, forming the desired image.
6. Using a hard sponge, sand both the surface of the plywood and the edges of the cuts.
7. The next step is to impregnate the material with a moisture-resistant composition (homemade mixture or industrial oil).
8. After the impregnation has dried, you can begin decorating.
9. A layer of stain and transparent acrylic varnish will not only protect the material from premature deterioration, but also create a beautiful glossy finish.

Filling buttons

Now it's time to secure the buttons into place in the pre-drilled holes. We insert the cambric into the buttons and put them in their place, as can be seen in the photo. Afterwards, you need to fasten them with drops of glue or hot melt glue. But this must be done carefully, so that there are no gaps left if you fill the buttons with epoxy resin! Because my first panel, filled with epoxy, remained as a museum exhibit. The epoxy is very fluid and it seeped into the buttons and glued them together. Like this. I had to do everything anew and this time I filled the panel with hot glue. The buttons can be pre-glued, so as to secure them in place, with a two-component, instant glue used by furniture makers for gluing MDF, sold in the same place as aluminum profiles - in furniture fittings stores.

Of course, before pouring, you need to solder all the wires to the buttons and LEDs as you can see in the photographs. This all adds up to a durable, waterproof and non-removable keypad, as well as a beautiful design that can be applied to any entry door, safe or garage door. Also, the device can be used for security systems.

Now we drill two holes for screws to attach the panel. Also, one or two holes for LEDs (d=3mm). One of them (green light) on the right to indicate that the lock is open. The other one is not used, it can be connected to the power supply for a constant glow or through an additional button to illuminate the keyboard when it is pressed. Accordingly, the LED should be white (ultra bright), fixed so that the light flux is directed towards the buttons. You can cut another piece of the profile and attach it to the keypad on top, or even use a ready-made keyboard from a calculator or other devices. And if you make the front panel from plexiglass, then you will have a solution for illuminating the entire keyboard!

And lastly, the numbers can be applied ready-made, or you can draw them yourself using a felt-tip pen, and then cover the aluminum profile with simple tape. This is done immediately after drilling the holes for the buttons. Of course, there are a lot of wires in relation to devices on microcontrollers, but not everyone has the opportunity to make such devices. The essence of this lock is that even a person who does not have any special skills in radio electronics can assemble it. I bought the parts, assembled it over the weekend, hung it up and connected it. All. This circuit does not require any adjustments. And yet, the code can be changed at any time. All wires from the keyboard are connected inside the combination lock body. Don't forget to label each wire. I used self-adhesive labels for price tags.

I would like to note that over the past time, there are no obvious signs of abrasion on the buttons! Most likely due to the black plastic. They are used daily. But it doesn’t hurt to clean and change the code from time to time.

Setting up the kitchen

Taking into account the specifics of the application, kitchen crafts are made from dense, water-resistant plywood.

This material is not afraid of moisture and steam, so it can last for several years. Plywood is usually used to make carved shelves, boxes for storing spices and other necessary small items, cutting boards, hooks for potholders, and souvenir refrigerator magnets.

If you have some experience, you can assemble an entire kitchen set with your own hands, which will not differ from the products of furniture factories. To do this, use thick sheets of plywood, a jigsaw or a hacksaw. And of course, you need to have some free time and desire.

To perform such work, you will need a jigsaw, including a hand tool for cutting out the smallest details in the image. If you want to clarify something, please contact me!

Device power supply

The device is powered by an uninterruptible unit from Dantom . It has a built-in 12V/7A gel battery. You can assemble the same one, the circuit is very simple, it produces a constant small charging current (several milliamps with a fully charged battery, and 70 - 100 with a discharged one). This is enough to power several electric locks and electric strikes. Or make a smaller unit if you only have one door with a combination lock. Let's say on: L7812CV, LM317, KR142EN8B. Also, the system can be powered from switching power supplies.

Schematic diagram of power supply unit RIP

Printed circuit board BP RIP

In the proposed backup power supply (RPS) circuit, a moisture-proof transformer is used, but you can use any other 20-40 Watt, with an output voltage of 15-18 Volts. If there is only one car actuator under load, then a less powerful transformer will do. For several electric locks, the electrolytic capacitor C1 must have a higher capacitance than that indicated in the diagram - for a greater energy reserve when triggered and, accordingly, a smaller voltage drop across the load. Capacitor C2 – 0.1-0.33mF, C3 – 0.1-0.15mF. The radiator for IC1 is larger, about 100-150 cm2, since in a case with a battery, extra heating is not needed! The output load current for L7815CV is 1.5A. Moreover, if a plastic box is used as a housing, do not forget about the ventilation holes. Diode D8 and fuse FS2 serve as short circuit protection.

Security RIPs have a tamper button against unauthorized hacking of the device - we don’t need it. On the board, to connect wires, it is better to use soldering instead of terminals, as the most reliable method of fastening. Also, it is appropriate to play it safe and take the spare power wiring out of the room, in case of an unforeseen event (stuff happens in life).
