Received the name Mousebot, and his main highlight is that it is a way to see the light and then turns to it. All this thanks to two LEDs that capture the light.
Materials and tools for manufacture:
- one ball mouse;
- Two little motors;
- one toggle switch;
- microcircuit LM386;
- one DPDT 5V relay (you can also use AROMAT DS2ye-S-DC5V);
- transistor PN2222 NPN (and 2N3904 is suitable);
- one LED LED (color does not matter);
- transistor for 1 com;
- resistor on 10 com;
- capacitor per 100 mf;
- magneto cassette;
- diskette or CD disc;
- Battery for 9V with equipping;
- Rubber stripes and wires.
From the tools you will need: multimeter, cross screwdriver, pliers, drill, knife, soldering iron, plumbing, glue or epoxy, hot glue with gun and hacksaw.
Manufacturing process:
Step one. Disassemble the mouse and take out some details
After breaking the mouse, you need to remove the switch, as well as the infrared emitter, they will be needed for the manufacture of a robot. IR emitters and switch must be disappeared. The emitter is marked on the pictures with numbers 1 and 2, the switch is indicated by the number 3.
Step second. Preparation of the robot hull
To get as much space as possible in the robot case, you need to cut all extra protrusions from the inside of the mouse. The easiest way to do this with the help of a drenel. If the mouse is small, then maybe you will have to remove those projections in which the connecting screws are screwed. For cutting, the short cylindrical style is well suited. Being in a vertical position, it will cut at right angles with good quality.
Step Three. Making Robot Wheels
Since the axis of the engines is very small, to move the robot they need to be equipped with wheels. It is not better for these purposes, rollers from cassettes, former tape recorders, are suitable. Wheels are fixed to the axes with a superclone. Then the strip of rubber is taken and turns around the wheel, everything you need to do three turns, and the glue should be added to each half. Now the second one is glued on top of the already glued gum, it must be installed as in the photo.
Step fourth. Creating a layout and relay installation
It is best to apply a standard layout, while the mouse circuit will be simple, since the printed circuit board takes little space. It is necessary to install the relay and solder wires, contacts from 8 to 11 and from 6 to 9 are crossped with connecting pins. Next, you need to connect Contacts 1 and 8 and add a multicore wire for contacts 8 and 9.
Then you need to take the transistor and solder the 16th contact to its collector. Subsequently connected wires sold to contact 9.
After that, the relay can be glued to the housing. From the wire that connects the 9th contact with the contact of the emitter, you need to solder to the power wires. Contact 8 connects with a positive pole.
contacts 1, 4, 6, 8, 9, 11, 13, 16;
1 - Emitter; 2 - collector; 3 - Basic
Pitch fifth. Install the switch button
Now you need to take the switch and connect it as indicated on the diagram. The resistor used has a denomination of 10 com. So that no closures occur, the contacts are best to isolate with a shrink tube.
Step six. Connecting the brain robot.
The LM386 chip is used as a brain for a robot. It must be turned up and then bend the contacts 1 and 8 so that they come into contact, then need to be soldered. The microcircuit is then installed in the housing and connects. To contacts 2, 3 and 5 you need to add a multicore wire. And contacts 4 and 6 are connected to a plus. As a result, everything should look like shown in the photos.
Step seventh. Create an upper part of the robot
You need to take a drill and drill holes at the top of the mouse housing. Two holes are needed to connect the eye, and one to install the LED LED. In the back of the mouse, you need to make a large hole for the toggle switch. At the same stage, the switch can be installed.
To create eye stalks, you need to twist the copper wire, and then on their ends one contact is soldered by IR emitters. In the central hole, you can now install the LED, and a resistor per 1 com is sold to its positive contact.
Step eighth. Fixing elements
So that the engines and switches are securely, they must be fixed using hot glue or epoxy resin.
Currently, even from a computer mouse, you can make original things. Many fake lovers have long come up with how to apply a broken mouse.
Is it worth throwing an old computer mouse
Sometimes a computer mouse comes into disrepair, sometimes it is necessary to replace the outdated model to more modern because of the amenities. Often in this case appearance and content it remains in good condition. If you do not want to throw out the details of the computer, you can give them a new life using it to create interesting things.
What can be done from a computer mouse: ideas
External and internal details from the old device will be suitable for creating the following original things.
Robot
From the unnecessary ball mouse will be a photosensitive robot. For this, the details are disassembled, the switches and infrared emitter are left to work. The case needs to be released from unnecessary parts and protrusions, attach wheels wrapped with rubber ribbon in three layers. Next, you will need a relay to be installed inside the case, connect the necessary contacts and solder wiring. To work, the robot also takes a small chip, it must be placed inside the case. It remains to do two holes for the eyes and one for the LED lamp in the front and one hole for the toggle in the rear. Contacts, eyes and batteries are joined to the right and left engines. It turns on the robot with Tambler.
Flashlight
By inserting the LED inside the body, you can get a small lantern. In the same way, a small desktop stand or lamp is obtained. At the Wire Connection Place, the stand is attached, and the lighting lamp can be installed in the ball.
Important! You should not use as the backlight of the incandescent lamp. Heating, they can spoil plastic from which the mouse housing is made.
Tachometer
Using the board from the old mouse, a tachometer will turn out. Create transistors and LED fees. A resisther is soldered to the free hole of the controller, and contact from the photo-transistor is connected to the board connector. It remains to connect the tachometer through the connector to the computer. The resulting device calculates the rotation pulses per second and displays the data into the monitor.
Motalka
In the upper part of the case, a hole is thrown into which the adapter is placed with a comfortable nozzle. Such a winder will succeed in mechanical and will rotate due to the movement of the adapter.
What can be made from a variety of computer mice
If the mice from the computer accumulated a lot, you can use them, smearing:
Speakers
After breaking the plastic case and placing a small speaker there, you can get audio colors. To do this, unscrew a screwdriver, divide the device into two parts. Inside, place the speaker selected in size. Wiring must be cleaned, contacts and their compatibility with the color of the wire check the tester. Then, using a thermal oil, firmly fix the dynamics disk inside and connect both parts of the housing. Such a portable column is suitable for the phone, tablet, player, and even computer.
Tip! If you make a hole in the front of the mouse housing, the sound will be more powerful.
Robot Robocopa
This idea will succeed, if there are many broken mice from the computer. Of these, you can assemble the body and limbs of a complex robot. The role of such a craft can only be decorative, but if you provide a robot with an electrical mechanism, you can get an interesting toy that can move and emit light.
The so-called "mice" is an integral part of the modern computer. With the advent of new, old, still workable, but obsolete morally, as a rule, ejected or dust without affairs in the storage room. However, they can be used, practically without changing the electronic stuffing. Make it quite easily.
"Red Eye" includes light
It is not surprised by the original lights of light today, but presented below - from an optical computer mouse, in my opinion, unusual and convenient in the city apartment for several reasons:
- First, the miniature mouse Sven Dnepr well enters the socket under the regular keyboard switch on the wall;
- secondly, it is not necessary to direct contact with the switch - it is enough to carry out a finger (or another item) at a distance of 1.5 cm from the "red eye" of the backlight;
- Third, the device initially has the effect of a trigger: once spent his finger - the light caught fire, spent the second time - turned off;
- The response indicator is also provided - with a finger-wire with a "backlight", it lights up three times brighter.
The simplest aircraft amplifier on the transistor with the actuator in the collector circuit is added to the optical computer mouse, so that the signals from the mouse control the lighting lamp with a power up to 200 W (limited to the relay parameters) - about it below. Since almost all computer optical mice are built in one diagram and the principle of operation, consider one of them - Defender Optical 1330, presented in photo 1.
The main coordinate positioning device is a microsite with the designation U2 A2051B0323, combined with a photodetector (in one case). From the output of 6 of this microspectorate on the Red LED, the pulses are constantly entering the pulses with a frequency of about 1 kHz, so even when the optical mouse is without movement on the table, it is visible red, barely shimmering "backlight". However, its value is not only to highlight the place occupied by the mouse - for beauty. The LED is a transmitter, and the receiver serves the microsite for the electronic node built into its housing. When the light signals reflected from any surface reaches the photo reception, the voltage level at the output 6 U2 drops to zero, and the LED lights up in full force. It is such a reaction that we see the mouse on a computer desk when trying to move it.
The combustion time of the LED in full force is 1.3 s (if there are no longer influences on the mouse). One of the main parts of the optical mouse, oddly enough, not electronics, but a plastic lens, curved under a certain radius (see photo 2), without her mouse "blind".
Installing the mouse in the wall niche under the standard switch in the assembled body, which reliably fixes the optical lens from the base side (substrate) of the mouse.
When the photodemaker comes from the obstacle (your finger, palm) signal, at the conclusions 15 and 16 of the microspectors U1 NT82M398A (and, accordingly, the level of the logical signal to the opposite changes the opposite level. And these are not inverse conclusions, but independent of each other. Changing the signal on them occurs depending on the vertical or horizontal movement of the mouse. The control signal for the actuator (low level is replaced by high, output 15 U1 and output 4 U2) are connected to the actuator, to point A.
Opening the transistor and the switching on the relay occurs at a high logical level at point A. Diode VD1 protects the relay winding from reverse current shots. Resistor R1 limits the current in the transistor base. The relay can control not only the lighting lamp, but also by any load with a current to 3 A. The power source is stabilized, with a voltage of 5 in ± 20%. The transistor can be replaced by KT603, KT940, CT972 with any letter index, and the actuator K1 - on RMK-11105, TRU-5VDC-SB-SL or similar to the response voltage 4-5 V.
The four-conductive cable partially disappear from the board at the scene of the connection with the standard connector and turn the two wires (green and white to the conclusions 15 and 16 of the microspectors U1 from the side of the elements (not printed mounting), since otherwise the wires will interfere with the installation of the board in the mouse housing.
Initial splitting connector on the mouse board: 1st conclusion - general wire, 2nd conclusion - nutrition "+5 V", 3rd and 4-y-laimy impulses.
If the scheme and circuit board at your mouse do not correspond to the Defender Optical 1330 presented on the example, it is enough to take any oscilloscope or a logic probe (indicating at least two main states - high and low) and experienced way to find on the board with a control signal.
It is suitable for any optical mouse for PC, so there is no difference to which connector is located at the end of the computer mouse connecting cable, it will still have to be removed. You can also apply wireless mouses (with the transmission of the signal over the radio channel, for example, from the A4 TECH kit - the mouse adapter RX-9 5 in 180 mA), in terms of positioning the coordinates they have the same principle of work, as well as wired.
Watchman mouse
Now there is a new wave of changing generations of a common computer manipulator: "tailed" (with wires) optical mice are inferior to their wireless counterparts. For example, the Wireless Optical Optical Machine Mouses RP-650Z are relevant complete with a wireless keyboard (with an ergonomic location of the main keys and the 19th additional reprogrammable buttons). Agilent Technologies Sensor, used in the RP-650Z Mouse, is the leader of this market sector.
The optical mouse resolution is 800 DPI - this is quite enough for good work. A radio transmitter of the radio signal and charger of the AA type batteries with a switch for quick charging is placed in one case (photo 3). This unit is connected to the USB port.
A4Tech marks its manipulators with individual electronic code, thanks to which on one channel, reception can be adjacent to 256 manipulators or keyboards. Such a technical solution narrows the bandwidth of the data transfer, but with a maximum radius of confident reception of 2 meters it is not critical.
An unusual version of using a wireless mouse is as a signaling device for the opening of the safe, the operation of the washing machine and even ... The refrigerator is presented below. All these options are based on the subject's microsnotation and even on the effect of detonation. When installing the mouse on the metal door, the signaling device of its opening or exposure (one more application option) is obtained.
It should notice that an equally effective signaling device can be obtained if you install a car shock sensor on a controlled surface as a mouse; It also works from detonation or mechanical impact on a controlled surface, and its modern models have even several levels of sensitivity adjustment. In the computer mouse, this option is not for the definition of its first and main purpose, but it does not matter; After all, we consider its unusual application.
You constantly use the computer mouse (or expressing "prefaby" a mechanical manipulator that converts movement into the control signal), and have you ever wondered what can be made by a computer mouse? It turns out not so little. Select an object or copy it, move or delete, open, or close a file or folder, all and more can be performed by a computer mouse. That's about it and talk.
In this lesson, we will get acquainted with a computer mouse, we learn some secrets of it, and also learn what you can make a mouse on in the browser. You, with the mouse, you can choose a folder, file or some kind of program and perform some actions, move in the desktop area, open the folder or run the program. You can copy or remove a word or whole text.
Computer mice are ball, laser, wired, without wired. But the principle of work has the same. When you move the mouse over the surface of your table, the cursor moves on the monitor screen, duplicating your actions. The main buttons needed to work with the computer mouse are only three. This is the left and right key and the scroll wheel (Scrolling Scroll. Scroll). Using a computer mouse and additional keyboard buttons, you can easily simplify and facilitate many operations on the desktop, when working in programs and browsers. Let's get acquainted with some tricks of working with the mouse.
The simplest operation that you probably have already had to make it all the text. To do this, simply at the beginning of the text put the vertical slash. It is also called in English pIPE (in Russian you can safely utter "PIP") To do this, the left mouse button, click at the beginning of the text and climbing the left mouse button and lead (not releasing the button) before the place where the desired text ends. And what if the text is longer than the page size? Here you will help the next combination. Put the cursor at the beginning of the text, clamp the key, on the keyboard, Shift. And click on the left mouse button, without releasing the key on the keyboard, go to the end of the desired text and press the left key again. All text is highlighted, you can make further actions with it.
Copy and insert text.
You need, part or all the text, transfer to another place or folder. How to highlight the text, we already know how. Now, on the selected text, click the right mouse button and in the contextual (dropping) menu, find "copy" and click on this item. All the necessary information is saved in your exchange buffer (clipboard, if you do not delve into subtleties, temporary storage where you copied files, folders, text). Now find the place where you need to insert copied, click on it with the right mouse button and in the dropping menu, choose "Paste". These operations can be done in another way. Select the desired one, then clamp the keyboard keys Ctrl + C. All copied. You select a place where you need to insert copied, put a slash (one click left mouse button) in the right place and press the Ctrl + S. keys. All - the text is inserted.
Change the scale.
Sometimes, opening some kind of site or page and see that very small font. Not all, especially the elderly, have good eyesight and they are hard to read such a font. It turns out that it is easy enough to fix it. To do this, clamp the Ctrl key and scroll through the mouse wheel in before or backward. Accordingly, the font size will increase or decrease.
Open the link in the new tab.
You have already had to work on some kind of page, go to another page or tab, while not closing the first. At the same time, you made the following: "You click on the link to the link and select the menu in the opening menu - open the page in a new window." But all this process can be simplified. Click the Ctrl key and click on the link. Everything, the link will open in a new window.
Move using the right mouse button.
Move the folder or label in the desktop plane, you already know how. Who does not know how to tell. You clamp the left mouse button. The selected object and, without releasing, move to the selected place. And it turns out that this operation can be performed using the right button. The principle is the same. Press the right button and drag to the right place. When you release the key, the menu will open, where you will be asked about your further actions. Choose the desired one.
We highlight the word or text.
If you need to highlight some word, it is enough to bring the mouse cursor to the desired word and click on the left key twice. Is it possible in this way to allocate the necessary paragraph? Sure. Put the cursor again to the beginning of the text and click the left button three times. All the necessary paragraph is allocated, you can carry out further actions with it.
Third button.
Most users do not use the third mouse key. Few people know about its possibilities. And they can no less something. For example, when you open the browser page and click on the wheel, the cursor will change its view on the round. Now you can, leading the cursor in different directions, the movement of the page on the screen will also scroll into all directions, and the further the scrolling pointer moves, the faster the page is scrolled and will be. Sometimes it is very convenient when scrolling pages with large text.
These are small tricks of a computer mouse. We will stop on that. Of course, the topic is much wider than is set out, but throughout all subsequent lessons, we will return to this issue.
In the next lesson, we will get acquainted with the concept of a combination of keys. These are combinations of two or more keys by pressing which, you can perform tasks that usually require the use of a mouse or other indicating device. The shortcuts of the keys simplify work with a computer, saving time and strength when working with Windows and other programs ...
