Attention: RC-CAM.com will be closing down August 2021.

The RC-Cam.com forum was the very first online community dedicated to the advancement of wireless video cameras on radio controlled (R/C) models. This is now called "FPV" (First Person View). We are proud of the contributions that our members have made to the FPV hobby.

We've seen significant changes over the last twenty years. Initially there were a lot of eager R/C hobbyist that built their own video systems. Allowing these creative individuals to share their work was the purpose of this site. Now the FPV market is flooded with low cost systems; Sadly DiY FPV video projects are now rarely discussed.

RC-CAM.com (main site and forum) will be closing down August 2021. This is being announced now (March 2021) so that everyone has time to download any information that is important to them. After the site is shutdown the information will no longer be available here.

We appreciate every member's involvement with advancing the FPV hobby. It is indeed sad to say goodbye to all our online friends. Be safe and stay healthy.

  1. The mikroElektronika boards seem very useful for me also so far but after 30 years of embedded controller programming I shouldn't need such a board anymore, when the original hardware (DragonOSD) is available already . //Erwin
  2. Daniel, I know of course that the 6kB output possibilities of the demo is too low, was only curious of the IDE . In your case you're right of course not to buy a demo board but I hope you're able in the future to earn a little bit from the DragonOSD . Why not ? //Erwin
  3. Thanks Daniel ! Edit: just installed the demo of the mikroElektronika compiler and took a short look, must say an impressive IDE. Was surprised that mikroElektronika is here in Europe in Belgrad . Btw. have/had you also a DevBoard in use from mE ? //Erwin
  4. That's a good idea Daniel ! By the way, which C-compiler is necessary exactly for your source ? //Erwin
  5. No, unfortunately not, I tried to find it. But I think there should be no protocol, only standard I2C communication. There is a datasheet for the I2C ADC, the real name of the device is LTC2481 from Linear Technology. But as Daniel mentioned above I think also it would be cheaper to make your own board. By the way, I just ordered this tiny pressure sensor for only $9.90 for trying: http://www.futurlec.com/HP03D.shtml is also a I2C device. Cheers, //Erwin
  6. I've the mentioned Eagle Tree expansions in use (height, airspeed, servo current, memory expansion, etc.) and they are daisy chained via I2C not SPI (too many /CEs ), each of the sensors have a tiny I2C ADC onboard but not the memory expansion of course (see attached pic). //Erwin
  7. A lot is going on there in the meantime ... //Erwin
  8. Hi guys, here an interesting chip if anybody wants to build a voltage/current sensor with I2C interface http://focus.ti.com/docs/prod/folders/prin...et+PR+ina209-pr Cheers, //Erwin
  9. Very nice plane Terry, I like it also ! /Erwin
  10. Hi together, gave Oracle the first try at weekend and was an absolutely success at all ! Have in the moment only two self-made antennas connected (two 8 dBi patches are on the way from BWAV) but videolink was really impressive improved after attaching the Oracle controller. Attached a pic before wiring was finished. Congrats to the excellent work Mr. RC-Cam ! Cheers, Erwin
  11. Hi friends of FPV flying, here a relaxing little video from my FPV-Cularis. There are some dropouts due to antenna problems (new ground station with Oracle still needs some wiring) and the sun stands also very deep so the KX-131 had some problems: Higher resolution on megaupload: http://www.megaupload.com/?d=NC25P0VZ Lower resolution on YouTube: http://www.youtube.com/watch?v=GPPGGHbIh_Y Here some photos of the plane plus equipment: http://www.rcgroups.com/forums/showpost.ph...5&postcount=266 I hope it's not a problem to point to the neighbor universe ... Greet
  12. Hi Dan, really impressive work so far and I also like the layout and the font of the OSD very much ! Only the white flashing characters, a bit too bright in my opinion. Good luck for the further progress ... Like also the great idea to merge your OSD and MX's WPS2 ! Erwin
  13. Hi, the Eagle Tree Logger (I've one in use) has no sensors for the plane level as the FMA Co-Pilot, only for current, voltage, rpm, height and so on. And it's not able to control anything in the plane, it stores only data on board and/or send it to the ground station. Greets, Erwin
