Lems Ping Pong Box Rar Files
Around a year ago, whilst tap-dancing my way through a number on the VoiceLive 3, a little voice way in the back of my head asked if there was a way that I could do all the patch and effects changes just the onceIt looks like I wasn’t the only one that had that thought and the answer to that request is the VoiceLive 3 Extreme, or VL3X as TC Helicon calls it (and I will from now on). Due to the complexity and choices on offer by the original unit, there’s definitely a tipping point where the amount of physical input needed to effect all the changes begins to detract from the artist’s performance. So, the guys at TC Helicon have kept the same internal engine as the original VL3, but made changes and additions that are all about making your live performance easier.By far, the most significant new feature is the ability to record effect automation synced to a backing track.
In effect, with its expanded memory (four times the original) you can import up to 100 WAV or Mp3 files into the VL3X via a USB stick and assign one to any of the 250 presets. This is now ‘locked’ in to that preset, or song and you can pre-programme all your effects changes in advance, in rehearsals or at home. This can then free you up to concentrate on your performance on a gig, knowing that the overdrive on the guitar on the chorus, the backing vocals on the middle 8, or the ping-pong delay that you wanted on the last line of the bridge (but could never get right), will be there on cue, every time, every gig. The Backing track page in the LCD screen is very well laid out, with an overview of the whole track and REC, OVERDUB and UNDO features, all assigned to the corresponding footswitches on the unit. The UNDO feature is limitless until the data is saved to a Patch - although you can overwrite an effect change on a subsequent pass)This is surely a welcome addition for many solo performers, but this can only happen when playing along to an imported track as it uses the liner data to record and reproduce the changes - if it’s just you, then it’s back to manual patch and FX changes. Another caveat is that the extensive 3-channel Looper and the Backing Track feature playback are NOT exclusive, so you have to choose one or the other - I imagine however, that using the Looper would become a kind of backing track for a song anyway, so an acceptable trade off, in my opinion.On the rear of the unit, there is now a second, standard sized USB socket. As well as being used for importing tracks, it can also be used in the other direction for recording your complete performance on the VL3X.
This is set up by a two-button press on the top of the unit and records exactly what you hear from the balanced outputs. This is perfect for recording gigs/rehearsals, or even making CDs of your own copyright material.The floor unit is the same shape and size as its predecessor, but has traded the brushed aluminium casing for a sleek black version with an ‘Extreme’ black-on-black decal.
The screen and button layout is identical too - this was a great design in the first place and no need for change in my book.For those completely new to this unit, what we have here is a complete vocal and guitar performance unit. On the vocal side, there are 11 simultaneous effects, including Harmony accompaniment (up to 8 voices), TC Electronics quality Reverb and Delay, Hard-tune, Vocoder, Transducer (for distorted or filtered sounds) and more.
The guitar section is just as jam-packed, with over a dozen Amp models, Boost/Drive, Compression, TC Electronics quality Reverb, Delay and Chorus and more. Within each FX section, there are often two pages of parameter editing for minor editing.The button layout on the front has two distinct layers and the LED lights around each effect button glow BLUE for Vocal editing and RED for guitar. A third, PURPLE colour around a footswitch, shows that this will have an effect on both vocal and guitar when pressed. The magic ‘HIT’ button, front and centre can be assigned to turn on or off any vocal or guitar parameter on the fly - so you could turn off the delay and add some crunch to the guitar and add a three-part harmony with chorus to the lead vocal, all with one press of a button.The rear panel is very comprehensive and can accommodate any permutation of set up. The guitar input has a through output, so can be used for just analysing the key of a song (to set up harmony recognition for the vocals) and then put into an amp on stage. If you are using the guitar section of the VLX3, but want extra level control, then these have their own dedicated, processed outputs. The main/vocal outputs are on balanced XLR and can be set to mono/stereo, dry/FX or complete mix for both vocals and guitar.
Input for both Mic/line is on a combo Jack/XLR and can have phantom power switched via the set-up page. Along with MIDI in/out there’s an aux input and headphone output, both on mini jack.I’ve been using the original VoiceLive 3 for a while now as a dedicated guitar processor and it holds its own with the big boys (in fact on a recent tour, it had a couple of onboard functions that some others had to buy extra pedals to produce!). As a vocal processor, it’s top-notch and can get you a slick, Country style three part harmony with chorus and delay, a Kanye West ‘Auto Tune’ effect, then a nasty metal distorted and filtered effect all at the switch of a button.Add the new features to all these and TC Helicon have another winner.
Project overviewPing Pong Ball –cannon is a device which shoots ping pong –balls with either manual command from joystick or automatic command by machine vision. Shooting process is completely autonomous and user only needs to load more balls in the loading tube while operating in fully automatic mode.Cannon can be controlled in manual mode where movements can be controlled by a joystick.

In this mode user can trigger the cannon but actual shooting and reloading are still automated.In fully automatic mode cannon shoots targets defined in the machine vision software. Camera is mounted inside the box facing forward. User can adjust settings of machine vision in separate software on laptop, for example user can set safe colors, calibrate the aiming etc.
Technical descriptionLinks to the various attached technical documents:.Mechanical componentsThe Ping Pong Ball Cannon consists of four different sections. Box, rotating table, barrel assembly and the loading mechanism.Box is a stationary part and is used as a sturdy frame. Almost all of the equipment is attached to the box. All the necessary connectors for manual operation are found on the side of the box. Box is manufactured from 15 mm thick PVC sheet.Rotating table serves as mounting point for the barrel and the loading mechanism.

One servo is used for the panning motion of the cannon. There is also a small slot to denote the front middle position of the table.

Table can be adjusted to the middle position by loosening the middle screw and starting up the cannon. Then the servo drives to the middle position automatically and the table can be rotated accordingly.The barrel and the loading mechanism is attached to the table with a hexagonal mounting bracket. The cannon tilt movements are controlled also by a single servomotor connected to the mounting bracket. The axle between the bracket and the servo is only connected by one screw.
This might cause problems as slippage which causes the barrel zero position to shift. Correcting this problem requires the removing of the tilt-servo, restarting the cannon so the servo drives itself to the middle point and then reattaching it to the barrel when it is horizontal.Loading mechanism loads new ball in the barrel once cannon has fired. Loading holes are located in the barrel and loading barrel. When the loading cylinder moves the holes become aligned and new ball drops in to the barrel from loading tube. Cylinder movements have been limited so that cylinder’s force at extreme positions is not stressing any plastic parts.
If the loading barrel is removed, careful adjustment is needed that loading mechanism is not stressed by the cylinder. Cylinder speed and force can be controlled by pressure regulator and adjustable constrictor inside the box.

Please read carefully before trying operating the cannon. Electrical SafetyInside the box care has to be taken to avoid electrical shock. If you are unsure about anything unplug mains cable before touching anything.Live parts inside the box can be found on the back of the mains connector and on the power supply module.
Back of the mains connector is energized to mains voltage regardless of the power switch position when plugged in. While power switch is in the on-position, heat sinks of the power supply are energized to 130 VDC.
Also there might be hazardous voltages present even after machine has been unplugged due to high voltage capacitors in the power supply. Mechanical SafetyLoading actuator is pressurized as soon as air supply is connected.
Care has to be taken also while operating the cannon to avoid pinching fingers between the loading mechanism, especially if loading tube has been removed. Never try to manually load the cannon without loading tube while pneumatic system is pressurized.While Ping-Pong-balls are relatively light relative to their size, eye protection must be worn when being in the line of fire while the cannon is energized. PerformanceBased on the slow motion video of the firing cannon we managed to calculate a rough approximation of the muzzle velocity of the ball.
Since the camera recorded at 240 fps and the ball moved approximately 0,192 m in the time of two frames, this gives us a velocity of 23 m/s or 83 km/h. User manual SetupSetting up the cannon is fairly straightforward. The power cable, pressure cable, and joystick cable are all connected to the left side of the cannons lower structure.
The two USB-cables (for the web camera and arduino board) found inside the lower structure of the cannon are connected to a computer. At this moment, do not yet connect the arduino cable to the computer (white cable).The computer needs to have the processing software found on the following site in order to be able to analyze the webcams picture and communicate with the arduino. The setup for the processing program can be found. Replace the settings.txt file located at ProcessingTurret0613/data with the one provided in order to use the same setup for the program as we used.When starting up the cannon, first turn on the main power switch located at the left side of the lower structure, and then connect the arduino cable to the computer.The switch located at the cannons control panel enables and disables the cannons ability to fire and reload. The left and right button located at the top of the joystick increases and decreases the time the cannon shoots air when the cannon is fired. The on off switch sets the cannon in manual (off) or automatic (on) mode.
Manual modeMoving the joystick controls the cannons pan and tilt movement. The trigger on the joystick fires and reloads the cannon in one sequence. The big center button on top of the joystick is for manual reloading. Automatic modeIn autonomous mode the cannon shoots at any target it finds. Various settings for its functionality can be set trough the processing software.If the automatic mode is not working (the processing programs diagnostics section says that it is not connected to any arduino), it might be due to that the processing program is not connected to the arduino. The connection can be edited from the processing programs diagnostics section.
Full instructions for the processing software can be found on the website.MediaConclusions and suggestionsCurrent firing system works reliably but in the current state the ball trajectory is very unpredictable. This happens because of the placement of the O-ring at the end of the barrel. When the ball launches past the O-ring there is no barrel left to keep the flight of the ball in the right direction. Furthermore the ball spins in a random direction after launch which further damages the trajectory. For future improvements the launching principle would have to be revised in order to achieve better accuracy. One solution would be to replace the current barrel with a longer one, thus still enabling enough pressure to be built behind the O-ring and the ball, but also allowing the installation of a Hop-Up device at the later part of the barrel. The Hop-Up would give the ball a backspin which would probably lead to a more controlled trajectory.
Other possible improvements would be making the functionality of the cannon more reliable. Sometimes the whole cannon freezes during reloading and it is as of the moment unclear whether it is the software or power supply that is causing it. As of the moment the balls sometimes also gets stuck at the O-ring. AttachmentsCodeThe programming was done in the arduino enviroment. The control of the cannon is based on arduino built-in libraries. A copy of the code can be found down below.Circuit diagram.
