Step 1: select flash driveOver the years, flash drives have become smaller and larger. The required flash drive size is determined based on access to the target computer and the type of Keylogger used. For example, if you can access the target computer multiple times a day and are using a text only program, you can use a 1GB drive because you can retrieve data as needed. If you use a keyboard recorder to take screenshots, you need a larger drive to store screenshots.Step 2: understand the objectives.This step (the last branch) will determine the program and drive size you are using. If you can access the target computer more than once a day but cannot hide the drive, you can use a smaller drive to pull out files as needed. If you can hide the drive, you can use a larger drive with the program to capture the screen. If you have little access, you may want to use a program that will record on your computer and use a drive large enough to transfer files.The basic Keylogger records text only where the drive must remain in the computer. Here: http://www.mediafire.com/ f42j4zetr668dazThe keylogger that will run on the flash drive, and then you can remove the flash drive until the data can be retrieved. You can download it here: http://www.mediafire. com/ y4vp04kjlwbli2uStep 3:If you cannot access the computer to load programs and only want to record text, you can purchase hardware PS / 2 or USB Keylogger. They will automatically record the keystrokes entered by the keyboard and pass them to the computer. They work by plugging into the computer and then inserting the keyboard into the hardware Keylogger. You can then retrieve the data by unplugging and reinserting it into the computer and pressing the key combination to display the files on the computer.You can find this data by typing hardware Keylogger in Google or the search engine of your choice.This is my first guidance, please don't be harsh =)Step 4: alternative methodsIf you have a game keyboard with fast macro function like me, you can activate the fast macro at any time to record keystrokes, and then check it later;)

How can I connect usb keyboard to laptop?it means that your keyboard area opf laptop has been distroyed so you need to attach external keyboard. So you need to probably install the keyboard first------Voice control and keyboard shortcutsSpeech recognition usually refers to software that attempts to distinguish thousands of words in a human language. Voice control may refer to software used for sending operational commands to a computer or appliance. Voice control typically requires a much smaller vocabulary and thus is much easier to implement. Simple software combined with keyboard shortcuts, have the earliest potential for practically accurate voice control in Linux.------spilled soda on my keyboard.?Leave your laptop open. Turn it upside down and let it dry out for a day or two. DO NOT spray Windex or any other cleaner directly onto the keyboard. Spray a soft cloth and wipe the keys and inbetween the keys. If it still is not working right, you will probably have to send it back to the manufacturer. Check to see if it's covered under a warranty------Keyboard Concerto No. 11 (Haydn)Joseph Haydn's Keyboard Concerto No. 11 in D major (Hob. XVIII/11) was written between 1780 and 1783, and published in 1784. It was originally composed for harpsichord or fortepiano and scored for an orchestra in a relatively undeveloped galant style evident in his early works, and has a lively Hungarian Rondo finale. On the other hand, being a somewhat later composition, it also shows more similarities to Mozart's piano concertos than do Haydn's other keyboard concertos. Haydn and Mozart had probably become acquainted by 1784, which may explain the Mozartian influences that are discernible in the work. It consists of three movements: Vivace Un poco adagio Rondo all'UngareseThe first and second movements contain cadenzas. The original cadenzas, written by Haydn himself, have survived. The work is scored for solo keyboard (nowadays mostly played on piano) and an orchestra consisting of two oboes, two horns in D, and strings.------what is the best ways to clean the keyboard? i have dell computer and my keyboard is black....?That canned air is a waste of money. Its AIR! and it just blows the dust around to settle somewhere else. Your better off gently shaking the keyboard up side down or using a vac-um cleaner hose to pull the dust out. (and the cookie crumbs) Then take a light cleaner, Like Orange cleaner and spray it on a Q tip and wipe between the keys. Never spray directly on the keys and do not use anything that might be sticky, like dish soap. Then put some cleaner on a cloth and wipe the rest of the keyboard. I just did mine the other day and Its just like new.------My Esc key on my keyboard is jammed need help?Try removing the esc key from the keyboard if you can. Most likely there's a rock or something that might get it jammed in place------how much would it cost to fix keyboard?take the keyboard out if accessible,there probable is water nevertheless in it making it no longer carry out acceptable,it you do not be attentive to the thank you to take it out turn the computing gadget the opposite direction up so as that the water will drain,make confident that the battery is out and the ability is off,supply it a pair of days and notice what happens in the previous taking it in for upkeep,they are going to sock it to you in the event that they could fix it------Keyboard working only when other keys are pressedPower off the laptop. With it opened out, turn it upside-down and shake it a little bit. Do some crumbs, pet hairs, or such, come out? They could have been interfering with the action of the keys, so it is time to clean the keyboard. With some laptops, it is really easy to carefully take the keyboard out for replacement/cleaning - if you are lucky yours is like that. Note that some people suggest that using compressed air only blows the dirt further in to the computer, some people say that using a vacuum cleaner generates static electricity which can zap the computer. Either way it could cause a new problem, but I do not see any people reporting actual problems from doing either

Step 1: HardwareArduinoI want to use a small Arduino board to keep this version as compact as possible. I have some pro trinkets, but they can't be used well for keyboard and mouse simulation because USB is not fully implemented on trinkets. For this project, I used adafruit's 5V 16mhz itsy Bitsy, which can use the standard hid library as a USB keyboard and mouse.LeverThis is the type of joystick used in the game controller. They are two shafts and have a temporary switch when the lever is pushed in. They are easy to find online. If you only want to buy one, they can be between $4 and $10, but you can buy them in bulk on Amazon for about $11.Note that similar joysticks of adafruit and sparkfun have different pins from all the other pins you find on the Internet. Pay attention to it when you connect it.On Arduino, this project uses A0 as the switch, A1 as the X axis and A2 as the Y axis. This leaves 19 other input pins for you to be creative.The joystick 5V comes from the 5V USB power supply (marked as this on itsy Bitsy). It has a ground - connected to the Arduino ground.Step 2: SoftwareThe Arduino code is very simple. I've programmed some of the Lightroom keyboard shortcuts I use to rate pictures. Push the switch to switch between the magnifying glass ("e") and grid ("g") views. Moving the joystick left or right will go to the previous (left arrow) or next (right arrow) picture. The push rod adds a star ("[") upward and pushes down to remove the sign ("U"). (trust me, this makes sense for the way I rate images.) you can change the code to do anything.The main cycle first reads the switch status. If it changes from high to low, it switches and types' e 'or' g 'to switch between the loupe and grid views.Next, the program maps the analog values of the joystick (0 to 1024) to different ranges (- 5 to 5). The code recognizes the / - value 5 as an operation to send characters, so you must move the joystick near the end of its range to send keyboard shortcuts. Then they must pass 0 to send another keystroke. The code to do this is very short, and I think it is very elegant. The real effect is that you have to consciously manipulate your action, and it won't accidentally emit the same keystroke flow (that's what my first version of code did).You can use the analog values in the mouse library and joystick to control the cursor, scroll wheel, volume control or any other analog (ISH) function.Step 3: case, Part 1 - Design and cuttingThe bread board living on my desk just doesn't look cool and ergonomics are not ideal. It's time to design the case.This will be an ideal project for 3D printing cases. I don't have a 3D printer, but I do have a laser cutting machine, so it looks like a laser cutting project now. This design took a night to design in Adobe Illustrator, including the use of many different concepts, such as simple rods, more organic shapes of hinges cut by laser, and square shapes.I began to put the bread board at different heights and angles, and decided that a 30 angle at a height of about 80 to 100 mm from the table was comfortable. The final design looks a bit like a small flight joystick, which feels very comfortable to hold.The original Adobe Illustrator files and DXF and PDF versions are listed below. (DXF and PDF have not been tested on the laser cutter.) the file also includes top and side views of the joystick for you to use when arranging your own project.Two thicknesses of materials are used in this design. Everything except the top is 0.187 "practical" plywood from large local stores. A 2 'x 4' sheet is only about $8. The design uses 5mm as the thickness of. 187 "wood in the design, which is perfectly assembled. The top is 3mm plywood, which can provide additional clearance for the thumb grip on the joystick. This project also uses transparent acrylic resin.Some notes on the benefits of prototyping: I first used cardboard for test cutting and assembly, which helped to find a design error. When I first cut the woodblock, I also found that the top plate was very fragile, so I redesigned the label to increase additional strength. I also found that the joystick touched the side of the case, so I made two modifications: I will It's better to move the bracket to the center position. I used 3mm wood instead of 5mm on the top. All these changes are included in the uploaded design file - just make sure the top is cut from the thinner wood.Step 4: case, Part 2 - drawing and assemblyWith all the pieces cut, I made a final dry assembly and temporarily installed the joystick. Everything was fine, so I stuck all the pieces except the top. It was impossible to install the joystick after installing the top for later installation.The bottom right corner of the top will poke the bottom of my thumb, so I round it with the bottom four corners and polish it quickly.If you like the laser cut look, or if you're made of acrylic, you're done! I want to use my desktop better. I painted it with a layer of black paint, and then painted it with a few layers of rust oleum forged hammered burned amber. I used this product on the decoration of the table, so it connects the various parts. I also like the metallic quality of this pigment I cover up the inside of the finger joint, the top fits, so the paint won't damage the fit.The lever and Arduino are connected with black wire and shrink tube to make it look clean, and the wire is cut to the correct length when installed.The lever is tightened on the center pillar. My screws are a little long, so I screw them through unused wood to shorten them and polish the tips with a bench sander. Arduino has no mounting holes, so it is hot glued in place.After installing everything, I folded the top in place without bonding. It was tight enough to hold itself and was not structurally important.Step 5: completeThe completed project looks great on my desktop.

wireless keyboard or usb keyboard?Wireless can be subject to interference. USB can be unreliable especially if plugged into a hub. I would suggest a keyboard with a PS2 connection. If you look at the back of your computer you probably see two small round sockets sitting side by side. Usually they are colour coded green and blue or green and purple. The Green one is for the mouse and the blue/purple one is for the keyboard. If the colours are different if you look closely they will be stamped with a small picture of a keyboard and a mouse. The PS2 connection is better because that socket is devoted to the keyboard only. The same with the mouse------Isomorphic keyboardAn isomorphic keyboard is a musical input device consisting of a two-dimensional grid of note-controlling elements (such as buttons or keys) on which any given sequence and/or combination of musical intervals has the "same shape" on the keyboard wherever it occurs - within a key, across keys, across octaves, and across tunings------Keyboard Component ReleasesKeyboard Component cassettes had limited availability through direct mail or select markets. Only 4000 Keyboard Components were manufactured.------is it possible to use a computer without a mouse, just a keyboard?I think you actually can do everything through the keyboard. CTRL and ALT have alot to do with it....oh and tab------KeyBoard Quit Working Please Help?You did not say it, but I know you mean keyboard as like electric piano, not typing keyboard... 1) The power supply might have come unplugged from the keyboard 2) The power supply might now have a bad cord 3) The power supply may have died 4) The keyboard may have developed a bad power jack 5) The keyboard may have a blown internal fuse 6) The keyboard's power switch may have worn out. 7) The keyboard may have a bad, or damaged motherboard I know everyone hates this one... 8) Is the power supply plugged in? ( to the wall ) Even I've done that one...------Does anyone know of an in-place adjustable keyboard stand? [closed]Every keyboard stand I own is in-place adjustable as long as there are two extra people available to take the weight of the keyboard, one each end. If you are unlucky enough to have a 'very tricky' one, plenty of simple ones are available. I prefer an X-frame with a bracing cross-piece rather than the ones that take all the strain at the pivot.------Keyboard layoutDevanagari InScript bilingual keyboard layout has a common layout for all the Indian scripts. Most Indic scripts have the same phonetic character order. A person who knows InScript typing in one script can type in any other Indic script using dictation even without knowledge of that script.------How to Reduce Keyboard and Mouse ClicksThe clicking of the keyboard is called "Haptic" feedback, to emulate how a standard keyboard would sound and feel. On smart phones this feature can be turned of. I have mine off, as it is an annoying sound. I would check to see if your keyboard has an 'OFF' option for that effect. You can add low cost software or a separate noise gate for your mic that can stop the click sound, but your voice must be loud enough to trip the noise gate so your voice comes though. The first answer by Stephen Kendall is worth looking into as well, because reducing the original sources of noise helps other noise-cancelling tricks work better.------Spilled juice on laptop keyboard. And now its sticky.?Turn off your computer, remove the battery, then spray the keyboard with tuner wash. This is spray cleaner made for electronic components that will evaporate quickly and will not leave moisture behind that can cause problems for electronic components. You should be able to buy this at radio shack or any electronic supply store. After you are sure everything is dry replace battery and restart------Whats a good keyboard to get for someone intermediate?I used to be a major distributer of Casio. when you have big star musician using them, the keyboard has to be well built and reliable. For the money and quality, you can not go wrong with Casio. It is cheap in price but not in ton quality

Some of the keys on my USB keyboard aren't working?Well it is either the computer's USB port or the keyboard. Try using another USB port to plug your keyboard into. Try all USB ports. Use an extender or even a USB hub. If this don't work, it is the keyboard. In that case, you'll need a new one. Not made of money you say? No problem when running windows 7. Go to start and type "onscreen keyboard" and a fully working keyboard will appear on your screen. This can become annoying though. Use on screen keyboard if you can't get a physical one right away.------Can I use air duster to clean PC keyboard?I do not get what you mean by removing the keyboards. I use 50 PSI air for a compressor but I just take the keyboard to the cellar to blow it out. I do not need any screwdriver------which is better to buy an digital piano or Keyboard?What the first answer said is correct! For me I had both and on the keyboard when bored I would play around with the different sounds, but strictly for practicing I only used the pianos. I love my digital piano because it has weighted hammer action keys that feel and respond like the piano that's more important to me------Whats the problem with my keyboard?Are you using a desktop computer? Try to unplug the keyboard, restart your computer then plug it back in, if it's no use.buy another keyboard.if it's your laptop it might a hardware issue, might wanna send it to a service center------Strange thing happens with my keyboardA cleaning of the keyboard will solve this problem------HELP, HELP, HELP! Mouse pee on a keyboard?Well, you should just take a wet tissue and wipe it. Hold the keyboard so the pee leaks out, if there is any left. Then, if you have like a spray, spray it! Add a little lotion or soap, so it smells good. If your mom asks, just tell her you sneezed, and then had to wipe it off. Just overpower the scent with soapish smells. Good luck, and hopefully you will escape trouble!.------Sticky juice in my keyboard, how can i clean it please?You can remove all the keys (Be shure to put them back on the correct place again! use a marker or something to mark the space underneath the keys) and clean the keyboard and the underside of the keys. To remove them, it usually enought to use a knife or a small screwdriver and pry them off CAREFULLY! (you are warned. Do not blame me if you break something) To put them back, just align them properly and press them firmly onto the keyboard.------can i adapt keyboard to playstation 3?I am not entirely sure if the keyboard will conform to the video game's controls or not. I've never tried it. But I do know that the PS3 interface and browser etc. work with any USB keyboard. I would suggest you use a wireless keyboard unless you like sitting really close to your TV.------How do you successfully clean a keyboard?This is a pain, but it works. Pop out all of the keys.just take like uhmm, a nail clipper thing with the cleaner.or something thin, and stick it under and pop them out. Then soak those in a thing of like soapy water or water and windex. Then take a Q tip or whatever and clean inside the keyboard.not having the keys there makes it much easier. Dry and scrub off the keys and pop them back on. It helps to have an extra keyboard around the match the keys up. Good luck.------Whats wrong with the numbers on my keyboard ?change the keyboard..? hehe.. i think you have a virus.. some virus 'scanners' get it all wrong once your pc's infected.. some are not updated.. unreliable and all that.. unless it's a really good and expensive one.. hehe.. anyway good luck.. but, i still think you have a virus of some sort : ).------One of the keys on my keyboard got pulled and raised a little,Help please?i recently had that problem............in case you seem below keyboard there must be some screws that you will be able to undo to seperate the best from the again of the keyboard. gently sparkling the factors with cotton buds and cleansing wipes and then re-connect. This solved my 'sticky' keys........desire it helps you..... :)

Step 1: HardwareI used Texas Instruments (TI) MSP430 launchpad to enter the field of microcontrollers, so I chose to use its USB chip. It turned out to be a rather poor investment. First, since the keyboard will always be plugged into the computer, the ultra-low power function of MSP430 is not required. Second, trackpoint is essentially a PS / 2 mouse. It uses 5V as the power supply. Using the 3.3V MSP430 requires a logic level converter. Third, USB chips are expensive. During the development process, I learned about the v-usb of AVR, which can convert most ATMEL 8-bit microcontrollers into USB microcontrollers. It uses a 5V power cord, which is the same as trackpoint, and the chip will be cheaper. However, it was late because I had spent a lot of time learning MSP430 series, and the AVR development board and programmers exceeded my budget at that time.In general, the keyboard requires a minimum of 28 lines of input / output lines for 16 lines, 8 columns, 1 FN line and 3 PS / 2 lines. Although three PS / 2 lines are required, one of them is used for the controller to reset trackpoint, so only two logic level converters are required.The final hardware design is the minimum requirement for using USB function on MSP430 line. This button is used to refresh the firmware via USB using the bootstrap loader mode of MSP430.From the schematic diagram of ThinkPad T60 computer, it can be found that the keyboard socket used is manufactured by Jae with part number aa01b-s040va1.The goal is to save as much money as possible during the prototyping phase. Since 50X50mm is the smallest and cheapest choice provided by the cheapest PCB manufacturer, the PCB design should adapt to these boundaries.Step 2: SoftwareIn the code, the keyboard matrix consists of the keying codes in the USB HID usage table (page 53). It is written as a one-dimensional array, organized in a manner similar to that shown in the table: 8 rows x 16 columns. In the firmware provided (next step), the matrix will be listed from address 0xF000. The number is the hexadecimal code of the corresponding key in the matrix. You can edit the hex code in this firmware file to change the matrix to a keyboard matrix as needed.I originally planned to write PC software to allow users to customize the matrix and add custom keyboard combinations. However, since not many people will know whether the keyboard socket of laptop is the same as my keyboard socket, it is useless, and adding custom keyboard combinations may slow down the speed of keyboard scanning. The end result may not be worth it.Step 3: DownloadThe project is closed source. Although the source code is written in C, it is divided into many source files and difficult to browse. I think it would be more beneficial to learn from the application notes provided by the microcontroller supplier without proper documentation.You can get the PCB from tindie. They have two flavors.

Step 1: keyboard in actionHere, you can briefly understand the performance of the keyboard in practical applications.The keyboard has two modes - step mode and continuous movement mode/ p》Step 2: collect everything!You will need to:-Arduino Pro micro 32u4 or mouse that mimics a USB PC keyboard-Button switch - I used a very expensive (20 dollars a piece) NKK kp02 switch. I used it from my friends. They are push-button switches with built-in RGB LEDs. But if you don't need fancy led effects, you can use any button switch at will. Alternatively, you can use some switches with regular RGB LED holes to slide in or slide in.-Tlc5940 IC (only if you need led effect). I used the IC itself, but you can use the splitter board if you don't intend to make your own PCB.-3D printer (optional)-PCB making skills (optional)-Basic electronic knowledge-For some time-And nerves:)Step 3: schematic diagramThe schematic diagram is very simple.I use some RC de dithering circuits on the switch (see Figure), so I don't have to worry about the switch bounce in the software. The LED in the switch has a common anode.For tlc5940 LED driver - I made my own PCB and welded the IC directly to the PCB. The resistance between Iref and GND sets the current that drives the LED.If you plan to use a breakout board, review the breakout board schematic. Connecting wires should be very simple.If you use a splitter board as an LED driver, you may not need to use 7 decoupling capacitors.Step 4: PCB and housingPCB is not an essential step in this tutorial, because I use a good program that I don't love my friends, and the purchase cost of my switch is very high, so I believe many of you won't make the PCB I make.I encourage you to use the distribution board and motherboard wiring connection project, or you can design your own PCB to adapt to more economical switches and LEDs.I designed a fast PCB in Altium designer. I use this program because I have a license because I use it every day. I know this program is far less expensive than hobbies.If someone wants Altium or PCB Gerber files to say in the comments, I'll send them to you.The box is drawn in Autodesk Inventor (it's not a good program to love friends, but I also use it at work. I'm used to it). If anyone wants a. STL file for 3D printing, please comment and send it to you.Step 5: SoftwareThe code is generated in the Arduino environment.I use the button library to manage all buttons. It has good functions and can read buttons like key. Uniquepress () and key. Ispressed (), making our life easier.The integrated Arduino keyboard library is used to make the circuit board work like a PC keyboard.Tlc5940 library, used to control LED dimming and complete all beautiful fade in and fade out.I attached the final Arduino code. The key is mapped to an additional image similar to a conventional PC keyboard in the code for ease of processing.Code can be easily modified for various purposes.Step 6: done!
