28 Мар. 2015 г.Hero cameraThe camera uses 2 AAA batteries which comprise a third of the weight of this tiny and light unit. This provides 3.3 volts at up to 2 mA (determined by measuring the current when shorting the pin to ground). The code was compiled with the free version of the IAR Embedded Workbench available from Texas Instruments.Go Pro HD Hero 2 camera is highly recommended for those that likes extreme sport or just wishes to capture some footage on which normal cameras would not work. Most often than not, the usual type of cameras would not be suitable for these types of activities due to the lack of durability. A simple controller that plugs into the bus connector on the back of the camera and takes time-lapse images every few minutes. The motion detector could be wired directly to the processor or interfaced as an RF remote control allowing more flexibility in placing the motion detector and maintaining the integrity of the waterproof camera. The HERO camera line incorporates a small digital camera enclosed in a waterproof housing unit, and the camera can take still or video pictures. The 3D HERO System housing is only 5 inches (130mm) in length and 2.5 inches high (62mm) and is compatible with existing GoPro mounting accessories. That is why Go Pro has released its HD Hero camera which is a very powerful and durable camera for almost all purposes. Next step is 8GB and higher frame rate or resolution to still fit in the 2hr battery limitation…or they could redesign for AA batteries. Waterproof to 180 feet, the 3D HERO System can be worn on the body, mounted on gear and vehicles, and used as a handheld camera. Based in Half Moon Bay, California, GoPro is the world’s leading activity image capture company. Even more important, complete development systems for small projects are available for as little as $4.30. Extreme sports require the same degree of camera so that all photos or videos can be taken with ease. About the author: Brian Mullin Brian has been part of the Mtbr team since 2007, where he has become an integral member of the review and test staff, specializing in technical articles. Instead of going to sleep, it remained on, depleting the battery in a few hours, even when there is lots of room left on the 32GB SD card. A dual-camera, polycarbonate, waterproof housing holds the two cameras together and a synchronization cable plugs into the back of each camera, enabling them to function as a single camera. The fastest rate on which it can go is at 120 fps on a WVGA resolution which is nonetheless a very impressive feat for a camera which costs only a fraction of what other professional cameras costs. The first thing I noticed was that the time lapse mode did not turn off the camera between shots. On interrupt, it decides what to do next which depends on where it is in the picture taking cycle. With both digital and analog signal inputs available to control the taking of photographs or starting and stopping video recording, there are options available that are only limited by your imagination. There is a great user forum following this camera, and gopropit has done some work deciphering the pinouts. In one button mode, if you turn on the camera, it will immediately take a photo†, or begin a sequence of photos, or start recording a video, depending on the settings that were saved before turning the camera off. The HD Hero 2 camera is has an 11 megapixel sensor which is capable of shooting videos up to full HD at 30 fps. Edo – myself and several others have posted some GoPro footage to the MTBR Video forums. It comes as a standalone version or various editions on which there are additional accessories given to suit the edition needed. The processor could be programmed to shoot several minutes of HD video each time the motion detector is triggered. Your input and feedback would help me decide which designs to work on and what features would make them more useful to you. This was a big head start that allowed me to design and build a controller in just a few hours. Some other editions that are available include Motorsports and Outdoor edition at a price of $299.99 each. If there is demand, we could arrange for the manufacture of these intelligent controllers for sale at a reasonable price. GoPro should be releasing a 4GB firmware upgrade shortly for the HERO camera, I do not have a time frame for the release. It is possible to change the shooting strategy if the battery is getting low or raise an alarm that the battery needs replacing. For example, the HD Hero 2 Surf Edition comes with the HD Hero 2 camera, a waterproof housing, a couple of surfboard mounts, a Floaty backdoor and a few other accessories.  That would allow the setting of a date and time for turn-on and very accurate timing between shots if required. The camera itself has only two buttons, an indicator light, and a small LCD screen that shows information relating to battery, mode, and status. Getting everything apart reminded me of trying to open a puzzle box, pulling the cover art off carefully so I did not tear it, and then pulling the tape off that holds the plastic top onto the main parts box. A small motion detector can be connected to the processor and used to trigger photos or video. The timer could also be interfaced with the RF remote control so that it would be possible to control the camera wirelessly, allowing full timer operation of the camera while it is protected by the waterproof housing. EZ430 USB stick ($20) and tiny F2012 project board (3 for $10) would be just perfect for this application. The workaround is to set the sequence time to P2, so that a photo is taken once every 2 seconds, and timing the power sequence to leave the camera on for 3 seconds. If you set up One Button recording in mode P, it will revert to PES mode, which takes a sequence of photos each time the camera is powered on. A simple two wire approach is used, similar to the LMC555 based shutter control used in my Kite Aerial Photography project a few years ago. The author assumes no liability for any damage which might occur to your camera or any warranty that these instructions will work for you. The only problem is that when the pin is grounded to take a picture, there won't be any power for the microprocessor. A small LCD display could be added to the processor board and used to program the real time clock in order to set up scheduled photos or videos or for the selection of different pre-programmed options. It should not matter if that is one a minute for a day and a half, or one an hour for several months. He likes to push the limits in all the sports he obsesses in, whether it's mountain biking, whitewater kayaking, extreme skiing, or sport climbing. That was solved with a capacitor, which is charged by the camera while waiting for the next picture taking cycle. GoPro’s 1080p HD HERO cameras are not included with the 3D HERO System and are sold separately, starting at $259.99 per camera. Much smaller ones are available than the one I had in my junk box, which is rather old technology. The 3D HERO System has an industry-first modular design that enables consumers to combine two 1080p HD HERO cameras to form a single 1080p 3D camera, the world’s smallest and least expensive one at that. The Hero comes in a cool box with a clear plastic top that shows off the camera in it’s housing. Pressing the button in various ways could be used to select among a number of pre-programmed configurations. After initializing the output and setting up the watchdog timer to interrupt every 256 mSec, it goes to sleep. For maximum efficiency, turn off the LCD, LED and beeper and operate the camera in stealth mode to reduce power consumption. The GoPro HD Hero Camera is an amazing little unit that comes with a variety of mounting accessories making it ideal for attaching to my helmet when I am paragliding, or to my car when I am driving. Originally released in 2006, the HERO cameras are a line patented by GoPro, a northern California-based team of inventors and athletes dedicated to making it easy to use a camera during favorite activities. Announced on March 30, GoPro acquired CineForm, a leading video compression software company famous in the film and broadcast industry for their high quality compression and editing applications. Inexpensive remote control timers (intervalometers) are available for many cameras on eBay for under $20. Or setting up time-lapse photos that are only taken during the day, controlled by a photocell. MSP430 microprocessor platform of ultra-low power 16-bit RISC mixed-signal microcontrollers from TI provides the ultimate solution for a wide range of low power and portable applications. Donations to support my time and effort and contributions toward the hosting and bandwidth for the web site are gratefully accepted. There are just so many options available once you can control it with your own custom programmed microprocessor. After taking a picture, the camera is turned off until it is woken up to take another photo. This saves the need for adding push buttons to the processor board and allows for control without opening the case.  |
