![]() I doubt I'll keep this raw footage available for very long. ![]() The actual flight starts at 1:20 and ends at 5:21. The raw video isn't edited so there's a lot of video watching the grass grow in it. I think this feature is a nice addition since if a file isn't closed correctly, it will become corrupted.Įdit(9/4/12): I've added the raw 0.5Gig file to my public DropBox folder. My first flight with the camera lasted long enough for the cell powering the camera to get low enough to trigger the camera's automatic shutdown feature. I noticed the part of the fluctuation is caused by the LED flashing. It fluctuates between about 560mA and 600mA (this was in "automode"). With a 4.0V supply, it draws about 600mA of current. I'll need to redesign my enclosure to keep the edge out of the picture. One problem I hadn't anticipated was the edge of the enclosure was visible since the lens has such a wide angle. I used cable ties to attach this to my quadcopter and it worked pretty well. I made a DIY enclosure out of some plastic sheet with a Plexiglass front panel. I may need to use a microSD card sniffer to access the card with a microcontroller.Įdit(9/2/12): I flew this camera with my quadcopter today. They don't appear to be connected to the SD socket. (I want to be able to keep video from just before the trigger event.) There are five holes above the SD card that I bet will make this easier.Įdit: It looks like I was wrong about the five holes above the SD card holder. I want to see if I can have the microcontroller tap into the SD card pins and delete unwanted files so this could be used to to continually monitor a location with old files being deleted and only keeping files after some trigger event has occurred. This camera should be very easy to control with a microcontroller. You could also have the microcontroller monitor the LED pin to make sure the camera really is recording when it should be. I'd suggest making the pin an input during the times the you don't want the button to seem pressed. It would be easy to use a microcontroller to turn the camera on and off by setting an I/O pin to output and setting the pin low for a fraction of a second to act as a button. I didn't connect a button to the camera, I just used a wire on the "button" pin and touched the wire to ground to start and stop the recording. I connected the video out and ground to an RCA connector and viewed the video as it was recording on a NTSC monitor. I just stuck the leads of an LED into the "LED" and ground pins and the LED worked fine. I don't have many single cell LiPos so I used the charge jack on a two cell LiPo to tap into a single cell. A two minute nine second video generated a file of 199,915KB. The recordings are about 100MB per minute. I was surprised to see the Class 2 card seemed to work just fine. I've recorded video using both a Class 6 and a Class 2 microSD card. I finally got a chance to play with this camera a bit. You probably have those things laying around, why pay twice? The included instruction manual mentions a battery holder, pushbutton, LED, SD card, etc. Note: To save you a few bucks, we're selling just the camera by itself. An LED can be attached to the LED output as an indicator of the camera's status. The HackHD also has a composite video output which can be viewed while it's recording as well as an external audio input which overrides the on-board microphone when used. Video is recorded onto a microSD card (not included) and the HackHD supports cards up to 32GB. ![]() Because recording is triggered with a simple button-press, it can easily be controlled using a microcontroller or simple sensor. Just attach a 3.7V Li-Po battery or other 3.7V source and a pushbutton and you have a fully functional camcorder. So why not use a video camera that was *designed *for hacking? The HackHD is a bare-bones camera that records 1080P video at 30 frames-per-second. ![]() The downside is that traditional video cameras can be heavy, difficult to mount, and triggering them to record can require some hacking. Capturing high-definition video is a challenge for any project, but a great way to see where you're project has been, especially if it's something like an autonomous robot or a high-altitude balloon. ![]()
