Camera On A Eagle!
LoopForEver replied to robyr1's topic in Wireless Video Antenna Problems and Solutions
Nice R/C Plane you got there, does it have remote control? ;-) Are you sure you TX is for 12V?, sometimes there is a 5V regulator inside the cable.. Guess it ok, because else it have probaly already fried! What is the name of your TX? Seems also like you recorder or PC have made some bad frame dropping, try useing a good Hi8 / miniDV camcorder with A/V in instead. Did see a danish program some years ago with a world campion woman paraglider trying to get a eagle to find good termal spots(Parahawking), for her, here they did also put a onboard cam on the eagle. Found the onb -

My little NAV/OSD project - under construction
LoopForEver replied to Daniel Wee's topic in R/C Electronic Projects
Great with all the updates :-) What about a R/L+R/C filter +3.3V reg, also on power from ESC? (I see thats how they do it on radio receivers) Also got alot of noise coming out on my ESC! Will see if i build it - need the BOB-4 OSD and its a little too expensive for now. Also my plane have crashed! (Lost radio contact when doing some radio control switching stuff in midair..hehe) But it will soon be working again LoopForEver -

Wow..looks really expressive :-) And its works well without acc/gyro/fma copilot and with the very small plane is also some of a archivement. Are the board only powered by the cell battery on the board? LoopForEver -

You could also glue the cam to the wing with some velcro or something. Or put 2 cams on plane, so you can switch view ;-) Really nice OSD you got, good with the heading locator. The "flyhome" function is also good in case something bad happen. Got waypoint navigation working yet? Looking forward to see more pics LoopForEver -

The term "Fly high" gets a whole new meaning Mann you high up, next stop 2KMs ? hehe Can't you mount the cam at a better spot, to get a better ground view, and still see the prop for RPM? Regrads LoopForEver -
Nice project Will be ideal with the Intelligent Flight OSD, when example you get out of range, it can automatic come back home. Later it could also be cool with planned waypoint navigation.. Also looked what sensors to use for autopilot, and come up with Thermophiles and GPS for a *good* start, ofcause more smart stuff can be added later, but will probaly fly well with just thoose sensors. GPS is pretty good for Altimeter when you not making loops and bad things, hehe - just average everything and its get even better - A static/dynamic pressure sensor, can maybe also be used as a

Maybe - when i put a resistor in between about 100R it work ok, but sync with OSD is bad then.. Have traced back at the video line. OUT < 75R resistor < SMD Coil < 100uF cap < ? The cam come with a BNC>RCA converter, ok? The cam is like this - just ist a 1/4 and PAL http://cgi.ebay.com/Sharp-1-3-CCD-COLOR-CA...1QQcmdZViewItem Also got a NTSC version of cam, but have not tryed that one yet. LoopForEver

>Kilrah A chinese TV capture card on a laptop, not the best one hehe But its the Sharp cam there is bad. I used a pot with center leg to video source from cam, right leg to "video out", and left leg to ground. So im putting resistence+a little ground to get light down. But as Thomas writes sync will fail with OSD, any other way to get light down? btw Thomas The video fix worked fine - much more black text now, but still sync problems.

Hi, Tested the new Intelligent Flight OSD for the first time - works like a dream My Sharp 1/4 CCD have some trouble with too much light.. (Anyone have a fix/solution for that?) So video is very light, and top bar sometimes disapper - but a video fix for the OSD will make the top bar much better. btw. Do anyone know where i can buy the KX131 or KX151 or a OEM of this cam, cheap? Youtube video: Pictures: LoopForEver

>1/4 of a wavelenght * 0.9 = the wire you need >use a wire that is thick and stiff so it will stay straight, >but not too stiff so the board will brake if you touch it, >alternative strongen to solder mount point with hot melt glue. Done that, so thats good :-) Its it better to point antenna down under the plane(vertical), than upwards? Some years ago i builded a Ground Plane ant for the cheap CMOS china systems, and it worked better than a simple whip.(But not if plane is just over ant!) >0,03039 meters is 30,39 mm >but remember the shortting factor 0.9 >

Hi, How long do the TX whip antenna need to be, to get best result? 1/2, 1/4, 1/8? (With Airwave 450mW and 10mW module) What wire size(mm2) to use - don't matter? Example for CH4: 300/2468=0,122*0.25=0,03039 So about 30,39 mm for CH4? Right now i have just soldered a 0.25mm2 wire to the RF out pad, length=30mm, with no SMA or COAX or Shield, just connected directy - vertical. ok? Its a Ground Plane better? http://www.yb2normal.com/antenna3.html LoopForEver

Hi, Also have a Sharp 1/4" CCD cam, and it also make some noise i found out. Tryed powered the cam from the RX receiver batttery - know is not so good to do so - and servos flipped alot only at short distance, so guess it make some noise! How much db sensitivity is the Dynam R6P on? Will try to check out crystal in cam etc. LoopForEver
