1. When connecting the valve sensor you want to plug it into the Sensor1 port on the Camera Axe To trigger your camera there are two options The first is to trigger it manually with a fairly long exposure like 5 seconds just before you activate the valve sensor The second option and think this is a little easier is to connect your camera to the Camera Axe s Camera Flash 1 port and put your camera s exposure to bulb so the Camera Axe can trigger your camera You will need to connect one or more flashes to the Camera Flash 2 port The valve menu will trigger the camera attached to Camera Flash 1 port 100ms before triggering the first droplet and will turn off the camera 200 ms after the flash is fired when attached to Camera Flash 2 port The rest of the timing is determined by the parameters in the valve menu For more detail on using the Camera Axe with the valve sensor and this example see the tutorial at http www cameraaxe com wiki index php title ValveSensor Photogate Sensor This photogate sensor which plugs into either of the Sensor ports on the Camera Axe detects when something passes through the gate Great for detecting well aimed bullets water droplets or anything that can pass through the 0 4 inch gap This functions very similar to the light sensor and the laser but this plugs into a single sensor port and is easier to setup for small objects Motion Distance Sensor This sensor which plugs into either of the Sensor ports on2. so this should be set to a value of Low when using the projectile sensor described below Set to determine whether the user provided distance is in inches or centimeters The distance is measured from Sensor 2 to where you want the projectile when the flash fires See the section below for more details and example of how to use this menu with the projectile sensor Valve Menu Due to the display size the entire menu shown below is not visible at the same time Pressing the up and down arrows will scroll the display to show the rest of the menu This is a special purpose menu for the valve sensor The menu parameter settings are described in the table below The following settings are useful for a 1 valve setup The valve sensor should be plugged into the Sensor 1 port Parameter Options Description V1 Drop1 Size Numeric value The number of milliseconds that the valve will be between 000 and open to release a drop 999 V1 Drop2 Delay Numeric value The number of milliseconds after the first drop to between 000 and start the second drop 999 V1 Drop2 Size Numeric value The number of milliseconds that the valve will be between 000 and open to release the second drop 999 Flash Delay Numeric value The number of milliseconds to wait after the between 000 and second drop to trigger the flash 999 Flash Delay Auto Numeric value The number of milliseconds to automatically Inc between 0 and 9 increase the flash delay bet

4. the Camera Axe detects the distance of an object from the sensor It updates its measurement 20 times per second so won t work for really fast moving objects but it is ideal for wildlife Its max distance is about 10 feet 3 meters The object it is detecting must be the size of a small bird or larger and it is accurate enough to detect a movement of just a few inches Camera Shutter Sync Sensor This Camera Shutter Sync sensor which plugs into either of the sensor ports on the Camera Axe detects when the shutter of your camera is open To use this your camera must have a pc sync port By default most cameras will trigger this when the shutter has just opened front curtain sync but most cameras have an option to also trigger just before the shutter closes end curtain sync Read your camera manual for more details on what options are available on your camera Clip Sensor conductivity between the clips changes This Clip sensor which plugs into either of the sensor ports on the Camera Axe is a generic sensor for people who want to make their sensor This sensor can trigger the Camera Axe when the Examples of how this could be used would be to add any of the following between the two clips a manual button two sheets of tinfoil the touch each other when someone steps on it a thin metal trip wire a photo resistor or many other things Multi Flash Board This board plugs into the one of the Camera Axe s Camera Flash ports a
5. the internal battery On the Camera Axe Shield the USB port is located on the Arduino board This can be used to power the Camera Axe shield or to reprogram the board The Arduino also has a 2 1mm dc jack that can provide power It accepts 6 12V DC power Menus The Camera Axe provides several different sets of menu operations as described below Based on the pressing of the Activate button the Camera Axe will either be in the menu or photo mode When the Camera Axe is in the menu mode the various settings can be adjusted according to the description below When the Camera Axe is in photo mode the unit is monitoring the sensors and is ready to trigger an image NOTE Except for the settings in the General Settings menu the settings in each menu are independent For example the settings in the Advanced Sensor menu do not affect the operation of the Camera Axe when using the Projectile Valve or Intervalometer menus Depending on the menu function there are two different ways that the Camera Axe reads sensor values Depending on the menu function there various ways the middle sensor pin works e analogRead This returns an analog value between 0 and 1023 proportional to the sensor voltage of 0 to 5 volts The Camera Axe displays values from 0 to 999 This is the slower way to read the sensor value still quite fast at 20 microseconds but it provides the ability to read the range of values from the sensor This method is used

9. at the desired setting value the Select button is pressed again to exit the edit mode From here the Arrow buttons can be used to navigate to another parameter if necessary Once all of the settings have been adjusted as desired the Activate button is pressed to enter the photo mode At this point the sensors are active and a picture can be taken When done taking images press the Activate button again to re enter the menu mode and repeat the process Camera Flash LEDs The LED next to the Camera Flash 1 and Camera Flash 2 labels indicate when the device is triggered A green color means the focus line is active A red color means the shutter line is active An orange color means both the focus and shutter lines are active The focus line can also mean that the camera is being kept in in a ready state if auto focus has been disabled which will give a shorter shutter lag on most cameras Camera Flash Ports Two of the 3 5 mm jacks on the side of the Camera Axe are camera flash ports These ports are labeled Camera Flash 1 and Camera Flash 2 These ports are used to connect either a camera or flash to be triggered The Camera Flash 1 port is named Device 1 in the menus and the Camera Flash 2 port is named Device 2 The way the Camera Axe triggers cameras and flashes is by allowing current to pass through and the camera or flash provides the voltage It works like a switch There is a wide range of camera cables and cameras supported by the Camer

12. elay 00 00 05 This would trigger a total of 8 shots The first one would be after 5 seconds with a 1 second shutter trigger The 2nd would be about a half second later with a 2 second shutter trigger the 3rd would have a 4 second shutter trigger and the 4th would have an 8 second shutter trigger The 5th through 8th shots would start at 1 minute 5 seconds from activation and would have shutter trigger times of 1 2 4 8 seconds respectively This menu is really only used for taking shots in the dark or with heavy neutral density filters on the lens because the shortest shutter times that can be done for a 4 shot HDR sequence would be 0 1 0 2 0 4 and 0 8 seconds The reason the minimum granularity 1 10th of a second is because many cameras don t allow a bulb time of less than this Even 1 10th of a second may be too quick for some cameras If you re have trouble with your camera not triggering reliably try increasing this One second should be a safe value for all cameras General Settings Menu The general settings menu allows the backlight to be turned on or off or set to stay on for 10 seconds after the last button press When the unit is set to turn off the backlight after 10 seconds pressing the Activate button to enter photo mode will also turn off the backlight The backlight is the largest contributing factor to power usage on the Camera Axe so turning it off greatly extends battery life This menu lets you control the startup mode and
