The most significant difference between DOCSIS 3.0 and 3.1 is that the latter can support download speeds 10 times faster than DOCSIS 3.0, up to 10Gbps. That's impressive, but unless you've got a particularly high-speed plan, that probably won't matter.
It is the best online music speed changer tool among the bunch. Not only is it mobile-friendly, but it also creates almost zero clutter when changing the speed of the file. Once you upload the audio track, change the tempo settings, select speed, and click on the change speed button. The algorithm will process the audio and let you download it within seconds.
It can be downloaded here(v8.25 - See change log at the end of this post - if the link points to the wrong version, clear your browser cache and retry; if the link does not work with Chrome, try a different browser)This zip file contains all the necessary files.
VideosOn some Spike games, like WWE-LE, you can replace the videos.You'll need ffmpeg; If needed, Pinball Browser will ask you to download it. Just follow the instructions.
To enable this feature, you first need to use the communication patch :- Connect your pc to your pin with a RS232 cable- Load a stock firmware in Pinball Browser- Specify the serial communication port in Pinball-Browser (Advanced tab); there is a 'test' button. At this stage, it should report that the "communication patch" is NOT installed.- Load the "commXXX.hex" patch that is included into the .zip you've downloaded (Advanced Tab / Load Patch button). If you have any error or warning during this, it probably means that the patch is not compatible with your pinball.- Save your patched firmware and upgrade your pin with it- Pinball Browser should now say that the communication is working when you redo the port test.Untill now, this feature has only been tested on ACD165LE and STLE141 (If you try this feature on a different pinball, please post a message here so that I can update this information).- More infohere
The attached file (4pcb_DOC.zip) contains all of the support files for making and flying 4pcb. Included in the zip file are:4pcb_ARD (folder) - Arduino project (Arduino 0022, .pde).4pcb_EAG (folder) - EAGLE board files and libraries (EAGLE 6.0.0 Light Edition).4pcb_EXE (folder) - Ground station executable (requires .NET Framework 2.0 or later).4pcb_GRB (folder) - Gerber files for PCB printing.4pcb_VB (folder) - Ground station source (Visual Basic Express 2008 or later).4pcb_BOM.xlsx - Bill of material in Excel format.4pcb_DIR.jpg - Coordinate system of quadrotor and IMU.4pcb_EXT.pdf - Details of external connections.4pcb_IMU.jpg - Image showing vibration mounting and wiring of Pololu minIMU-9.4pcb_SCH.pdf - PDF schematic of the board.Bill of Materials / Cost:The Bill of Materials (4pcb_BOM.xlsx) lists all the components required to put together one PCB quadrotor and ground station. The total cost to build the quadrotor is about $240. The ground station consists of a USB game controller, an XBee radio, and and XBee-to-USB adapter. If you don't already have these, they add an aditional $80 or so.Soldering:This board requires a good amount of surface-mount soldering, including passives as small as 0603 and four TSOP36 ICs. They can all be hand-soldered (no BGA or leadless).Additional Tools and Hardware:- Wire (22AWG and 28AWG stranded would work) and wire cutters/strippers.- Solder braid for cleaning up bridges.- FTDI cable for programming the Arduino Pro Mini.- Hex key set.- Double-sided foam mounting tape.Software:-EAGLEIf you want to modify the printed circuit board, you'll need EAGLE v6.0.0 or later. You can download it here. The free "Light Edition" is sufficient, even though the outline of the board is larger than 100x80mm limit (see Step 2). You will also need EAGLE to reference the board layout when placing components. (e.g. Type "show R32" in the board window command line to figure out where to put resistor R32.) There are no designators on the board itself.-ArduinoThe flight controller is written in the Arduino IDE. You can download the latest version from here. Make sure you set the board type to "Arudino Pro Mini (5V/16MHz) w/ ATmega328".-Visual Basic Express (Optional)The ground station is programmed in Visual Basic Express. If you want to modify the ground station software, you can download the free edition, Visual Basic Express 2010 from here.-.NET FrameworkThe ground station requires the .NET Framework runtime files. (Unfortunately, this makes it Windows-only.) These files come with Visual Basic 2010, so if you plan on modifying the ground station software, there's no need to download them separately. If you just want to run the ground station executable, you can download the .NET Framework runtime files from here.-Processing? (Optional)Although I haven't done so myself, it is possible to port the ground station software over to Processing, which would make it compatible with other operating systems. To read from the USB game controller, there is a third-party library called ProCONTROLL. I did some work with this for a XBee-based robot controller, the details of which are here. This could be a good starting point for making a non-Windows ground station.
A quadrotor has four motors that can spin at different speeds, so it seems reasonable that it has four "degrees of freedom" that can be controlled. The four controllable DOFs are:1. Throttle2. Pitch3. Roll4. YawHow those control inputs are derived and sent as radio commands to the quadrotor will be covered in a later Step. This Step focuses on how to get from those four commands (the inputs) to the four motor speeds (the outputs).You might be able to look at the image in the previous Step and intuitively figure out what the input/output mapping for a quadrotor should be. It's easiest to represent as a 4x4 matrix, which is just a table where the rows are inputs and the columns are outputs (or vice versa). This Step's image show the command matrix for a +-mode quadrotor with propeller directions indicated in the previous Step's image.A [+] indicates that the motor should be sped up in response to a positive input command.A [-] indicates that the motor should be slowed down in response to a positive input command.A [0] indicates that the motor speed is unaffected by a positive input command.Throttle, pitch, and roll work by increasing or decreasing the thrust produced by particular motors to create a net torque on the quadrotor frame. Yaw works on a different principle, using reaction torque from the motor to rotate the frame. The reaction torque for each motor is in the opposite direction as the propeller and is proportional to the drag seen by the propeller as it pushes through the air.
The ground station transmits the commands throttle, pitch, roll, yaw to the quadrotor based on user inputs. It consists of three parts: a user input device, an XBee radio as discussed in the previous step, and some software to map input device axes to commands.Input Device: Logitiech GamepadI chose to use a Logitech Dual Action gamepad as my input device. The first image shows how the Logitech gamepad's joystick axes get mapped to the four quadrotor commands. Experienced RC pilots might recognize this joystick layout as Mode 2. Unlike an RC radio, the throttle stick on the gamepad will be spring loaded. This makes it a little more difficult to hold altitude, but it's not too hard to get used to.You can use any other USB HID device as the controller, but you'll have to modify the ground station software to correctly map the joystick axes to the commands. I've also tried a flight simulator joystick. I didn't like the feel as much, but this was back when I was first learning how to fly it.You can also use a standard RC flight transmitter. In this case, you don't even need a computer for interfacing. An Arduino can read the pulse position modulation (PPM) signals from the transmitter's trainer port, and send out commands via XBee. Here's a guide on how to map signals from the transmitter's trainer port to the XBee.Interfacing Software:If you do decide to use a USB HID controller, you'll need some software running on a computer to interface with the controller and to send commands to the XBee radio. This software can also grab telemetry from the quadrotor and display it, or log it for later analysis.I wrote a simple ground station program in Visual Basic, which is included in the project documentation (Step 1). The executable is in the 4pcb_EXE folder and the source is in the 4pcb_VB folder. To run the executable, you'll need the .NET Framework runtime files, which can be downloaded from here. If you're interested in modifying the ground station software, you can use Visual Basic 2010 Express, which is free.My ground station is nowhere near as functional as it could be. First, only some of the trims are active and they don't save their values when you close the program. It also only logs the telemetry (in a text file called 4pcbdata.txt). It could do so much more - like display a virtual 3D quadrotor on the screen that mimics the orientation of the real quadrotor.The .NET-based ground station will only run in Windows. If you're on a different OS, you can still write ground station software in any programming language that can interface to HID game controllers and a virtual serial port (so, pretty much any language). One easy option is Processing, an application/GUI programming language with and Arduino-like IDE. There is a third-party library for Procssing called ProCONROLL which interfaces to HID controllers. I wrote a very quick Processing/ProCONTROLL-based ground station for controlling robots that could easily be modified to send the command packet needed for the quadrotor. 041b061a72
