  1. I'd say that You've been lucky! There are plenty of tales of woe out there. Burned screens, broken temples, bad connectors, bad modules etc. Or maybe I just fly too close to the sun!
  2. There is something to be said for Eagle Tree Systems OSD. http://www.eagletreesystems.com/OSD/OSD.htm It would give you both barometric and GPS readings as well as data logging. There are alot of accessories for it. They provide good service and they aren't likely to go out of buisness any time time soon. They have a new OSD in the works that looks great! http://www.rcgroups.com/forums/showthread....018&page=23 Hopefully it will be out soon. Their barometric altimeter is only rated for 1 meter resolution but that may be about all you can expect to get in your application.
  3. I wonder if the OLEDS will prove more robust than the LCD displays. My Fat Shark's now have spots just from exposure to overhead compact fluorescents. The video circuits seem to be getting flakey, the display tends to white out and get moire patterns when the camera is exposed to a bright light. My old 920's acted similarly just before they quit working. I'd be willing to spend more for something that would hold up better under the somewhat harsh conditions my goggles get subjected to.
  4. I'm suprised to hear that your land based 2.4ghz video setup has better range than your 75mhz RC controller. Maybe your receiver lacks sensativity. You might consider a better double conversion receiver and a longer antenna as Mr. RC-Cam suggested. Perhaps your equipment was only intended for close range and an upgrade is needed. Unfortunately I'm only familiar with the RC plane stuff. -Dave
  5. Try servo city. They have various servos, drivers and gear heads. http://www.servocity.com/html/servos___accessories.html -Dave
  6. http://www.dealextreme.com/search.dx/search.sma Dirt cheap AND the price includes shipping! They have alot of useful and not so useful stuff. -Dave
  7. Ho's on first? For $50 I'll sell you the schematic off the back of my TV! Think of the challenge! -Dave
  8. Very tempting! The screen displays look dynamite! Still, alot of unanswered questions. There is no picture of the OSD and even the actual weight and dimensions are undecided. The specs put the autopilot and return to home on the same line, raising the question can it actually follow waypoints or is it just a failsafe feature. The specs show a vario function, would that be from gps altitude alone? Most are not accurate enough to do that. There seems to be an arificial horizon, how is that supposed to work without IR sensors or an IMU? In theory bank angle can be calculated knowing speed
  9. Hi Steve! Thinking about it, there are some pitfalls to using a capture card. Some cards run slowly and have trouble presenting a picture in real time. This may be doubly true if you are using the computer to control the servos. It may be best and certainly simpler to feed the camera into a video monitor. To save money you could use a TV, the larger screen would be more impressive and more people could view it at the same time. -Dave
  10. Here's another solution. Advantages: Almost free! Uses joystick or mouse. Disadvantage: You'll need a seprate wire for each servo. http://users.swing.be/philippe.jadin/servoen.htm -Dave
  11. It sounds like you want to control your servos over a serial cable. I googled up these guys, seems fairly reasonable. http://www.imagesco.com/catalog/servobds/s...servoboard.html There are probably other solutions. Why not just feed the video signal up a wire to a capture board on the computer? The only other wrinkle might be sending the signals 20 feet without some sort of line driver, amp or buffer. Perhaps you can e-mail the people who make the servo board for advice. -Dave
  12. "Gizmo" has link to a sale on the now rare CX-161's here: http://www.rc-cam.com/forum/index.php?showtopic=1749 -Dave
  13. "Gizmo" has an excellent comparison of diffrent cameras on RC Groups. http://www.rcgroups.com/forums/showthread.php?t=631723 As to Web Cams, the 800X600 and "HD" cams look interesting. Getting the signal to the ground and viewing it is another matter. -Dave
  14. I believe Wallaguest's post shows a picture of a pinhole camera like yours with a wide angle lens on it. The link shows the lens he is using. He meant this lens should work on your camera. The link describes a "fish eye" lens but is really more of a standard lens. Probably why it fits. It may still be an improvement though not exactly what you were looking for. -Dave
