  1. I was thinking I could take the concept behind this toy I made and use it for visualizing vibrations on my glow powered trainer and using that info to reduce them etc. The concept (which is hardly new) is that if you strobe a light at the same frequency as an oscillating object, it will appear to be frozen in time because you only see it illuminated at the same point of each oscillation. For example if I put a UV reflective dot on a wheel, spin the wheel at 100RPM, and then strobe a UV light at 100Hz then the dot will appear frozen in time. It would be possible to place a few m
  2. CTS and RTS are only used when flow control is active. Clear To Send Request To Send as noted, the GPS units do not use them.
  3. 75Ohms is what I get. I was mistaken about it working with my other video reciever, they both give crappy washed out video while my cam corder is crystal clear. I'm thinking I must have knocked something loose inside because I really don't recall it being this way before.
  4. My Futaba S3114 jump around like mexican jumping beans when I get them that close to my 500mW video Tx I plan on doing something similar though.
  5. Also, if you want to save yourself a little time and the application while doing bench work you might want to pick up one or two of these. http://www.sparkfun.com/commerce/product_i...products_id=133 or http://www.acroname.com/robotics/parts/S13...L-INT-CONN.html You will of course probably want the level conversion integrated on board with your final version of the project, but these little guys are super handy when doing prototyping etc.
  6. I once made a setup with an airsoft gun on pan tilt base with a webcam that was all controllable via a web interface. Once the url got around we had to shut it off, people were trying to shoot the lights out and stuff. We kept the gun unloaded most of the time, but you could see it occasionally track you across the room, or feel it staring at the back of your head.
  7. Hey there, I'm home from a great day of flying. The bad thing is I crashed the heck out of my intended aircraft last night and had to use my glow powered aircraft instead. This meant a very long delay today while switching the camera over etc. I simply didn't have any time to do any good tests for you. Here is what I have though, I hope its helpful. After reviewing the flight video and checking google earth, I don't think my aircraft got any more than half a mile away in ground distance. I'm a poor judge in hight but at one point I got up a good bit, maybe 600 feet or more. I'm
  8. revo, I'm hopefully going flying tomorrow (Sunday the 11) with my 500mW 900Mhz video transmitter. If I get a chance, I'll get some ground tests for you so you can get a better idea of range near ground with both the camera and the controls. I'll post here when I have results.
  9. I got my transmitter from range video. www.rangevideo.com I'm not sure if 900Mhz or 2.4Ghz will work better for near ground transmission etc. In general, the higher you can get your transmitting and recieving antenna from the ground, the better signal you will get. As an example, with my 900Mhz 500mW transmitter, I get perfectly clear video from 1/3 mile away, my plane hit the ground and that range got reduces to about 100 yards due to the high underbrush. My guess is that even with line of sight (no trees or buildings) you will get nowhere near 2 mile range near the ground.
  10. I've been thinking how easy it would be to mount cheap lasers on the aircraft that 'shot' a pulsed beam. The target aircraft would have recievers mounted that would count a hit when shot with the beam. Better yet, airborne airsoft.
  11. I recently purchased a 500mW 900Mhz system from Range Video (excellent service btw) that included the camera, transmitter, and receiver. When I plug the video output of the receiver into my small 7 inch monitor, the picture is very poor. The image seems over exposed and the colors are washed out. If I plug the same system (using the same video cable) into my camcorder, it records a perfect picture. I have another receiver for a different wireless camera system (one of those Swann micro cams) that works fine on both the monitor and the camcorder. I'm a little confused as to what
  12. The Olimex ICD2 is the way to go for PIC programming. If you are a total newcomer to microcontrollers, you might want to try something simple like the PICAXE system. Take a look over at sparkfun. http://www.sparkfun.com/commerce/categorie...php?cPath=2_125 PICAXE makes getting into the game quite a bit easier.
  13. That is EXACTLY what I'm looking for. Does the video output stall when you take a still shot or anything funky like that?
  14. Hey guys, I just ordered a FPV setup with a Easystar, 900Mhz vid transmitter, and some other goodies. I got a KX131 camera to go with it, but I would really like to be able to take decent quality stills as well. 3.1 mega pixels would be satisfactory. ] There are two problems I would like to solve. First, I don't want the weight of both devices(video and still) on the aircraft. Second, I would like to know exactly what I'm taking snapshots of. If I mount the video and the still camera pointing in the same direction I can have a general idea of what my stills will capture, but I'm
  15. Success!! I followed the KISS principle and just made the PIC watch for a high pulse that was between 150 and 170us, it ignores everything else. Here is my lovely assistant Alyssa demonstrating how easy it is to press the X-Port button and get the LCD to report a HIT and light up an LED. Next step: Design a Air to Ground rocket launcher
