don't waste your time and money... better you get a ready made device..... seem's this would fit: HEADTRACKER greets, marcus

Hi Guys! here is a very much similar OSD and it seems that it is already available, but sold out until jan. 15, 2009 RV-OSD product support page it has a mode where it looks like the hud of a f16 and it also has a autopilot for returning home on signal los... sounds pretty cool.. Greets, Marcus

Thomas, is there a reference to your 434Mhz system? I would like to get away from the 35Mhz, too Greets, Marcus

Hi Thomas! My very congratulations! I know how hard it is to get a working PA. In an experimental project I tried building one of those to see if it could enhance the rc range: http://hem.passagen.se/communication/1wpa.html. Until now I did not succeed in fintuning the amp because of lacking tools.... (my oscilloscope is broken :c( ) Greets, Marcus

Hello cpt_kangaroo! The video was from Fred Van H. The file was named canari.mpeg. Here is the link: http://rc.video.online.fr/van_h/canari.mpg Hope it still works... it is copy&paste from the FPV thread... Best Greets, Marcus

VLC offers some good plugins... ;c) At least that was the breakthrough in the case of LabView

Some of them use LabView to make sophisticated ground station systems.... Or simply VisualBasic... Greets, Marcus

-AT-Boris & Mark Thanks for your additional interests. Since all my documentation and schematics are handdrawn (and you probably wont decipher a single line..hehe) I will have to redo them in some schematic program. The layout files are already available... but only in ABACOM SPRINT LAYOUT format... can you make use of this format? (*.lay) Greets, Marcus

Boris, no, currently the switching is untimed and happens almost instantly once either RSSI is only a bit higher or the LOS-alarm is low on one. In my room test this brought up some funny results. when I put my hands halfway between (close together) tx and my diversity rx, then on some times the switching was continously and I could see both status leds go bright and dark that fast, that it seemed as both were one. Yet, there were only little interference produced by the fast switching... mainly on the audiochannels, the video almost showed no sign of switching. In normal conditions you probably wont even recognize the switch besides the fact that one rx puts out a slightly brighter image than the other one. I am very happy with my design, I just need to put up the videos to show and satisfy you, too (at least in compare to HOW cheap the design was against a commercial kit). Unfortunately I only own a 320x240 mpeg4 recorder with a lousy quallity and even worse it is defect somehow, I can not record anything, only view live... anyone a cheap 640x480 recorder on sale? :c( Greets, Marcus

Phil and all, at first I had not even a clue about that all, too.... so I simply taught it all myself... Some first outdoor tests were performed today. I am totally stunned, the system performed super well, showed many times less dropouts in video (and that with my 0815 thrown together and unmatched diy Lambda/2 (6.5cm) Antennas) and best of all the quallity/fidelity of the video improved by a magnitude, too. Both, The quallity/fidelity and range of those cheap HONGKONG SYSTEMS CAN NOT COMPETE in any way... I will put up some sample videos shortly.... Greets, Marcus

The new code for the PIC16F88 is attached to the main post now...

hecko everyone, finally the project is build/done in a nice projectbox. I also added power/signal status led and a switching negative voltage source which I probably won't need since I use direct DC-coupling of all modulboards. But this way I also gained some first experiences at negative voltages... ;c) A word about how it performs in real life.... I only have done some minor indoor tests but the diversity switching already works super fast and fine (without any notice). The power LED also tells me now if I have a valid signal at all (it blinks/is off when you have no correct signal) and the receiver-status LEDs tells me which receiver is active. I maybe will also install a small LCD which then gives me info about signalstr., channels and receivers used and a display of the supply voltage. And speaking of voltage, the last thing will be a undervoltage cutoff to safe the batteries with an accoustical alarm some time before the cutoff (I have some free ADC channel and additional switch pin left). So finally this is going to be a fully-featured diversity or dual a/v receiver for an very low price which is was worth the DIY apporach instead of buying a commercial unit for 200 or even more Euros... If there is any interest, I will make the Schematics and/or PCB layouts available... Outdoor test will be done once the weather is a bit more friendly... ;c) Greets, Marcus

-AT-Mark Hi! Could you please describe your code / way of apporach to this project a bit closer? (or is there a separate threat?) I am very interested in replicating the Joystick-controll for my plane... Greets, Marcus

Terry, no problem, you are welcome. Would you mind in describing your own system a little closer? Maybe you thought of some neat features that I have missed... ;c) Greets, Marcus

*g* that's the other side of the medal... but I love to get my hands dirty in work...
