  1. Hi to all! i would like to fit a gyrocamera (bullet camera) on a motorbike! What i have to buy? I would like to to something like the M1's of Valentino Rossi, in motoGP. Maybe i need a servo (just 2 axis, really?) and a gyro, but what kind of products?? where to buy in Europe? what's the differences between the cheaper and the expensive gyros? thanks!
  2. I need a 5hz (or more!) GPS speed overlay unit, i have to see just the speed (kph), and no more. I'm looking for a good place in europe (and cheap), where?? thanks!
  3. yes, for my special productions (sure, not for RC!) i bought a digital COFDM video link: http://navtechsystems.co.uk/services/micro...ofdm_rover.html what do you think? i'm happy like a children with a new toy!
  4. did you tried a GoPro hero camera? it has an auto shot every 2 seconds!
  5. yes! thanks, this is the first thing wich i'll do it there!
  6. thanks Kilrah, yes, i have to test it. For this i bought also a 5W 1,2ghz transmitter also, so i will try with send with a 2w 2,4ghz from the boat, and send with a 2w 2,4ghz or 5w 1,2ghz trasnsmitter from the heli. But now, i need 2 good antennas of 1,2ghz, where can i buy it?? another question: what kind of antennas i should to use there for the tx of the boat, the receiver on the heli, the tx on the heli and the rx at ground? here what i have: common stilo 2db omni, patch, parabolic and directionals (but all 2,4ghz)
  7. Hi guys!! i have another question from my customer! the day before the race, they want to put a wireless camera and send a live video for a 1km of high speed only. What do you think if i use a 2w tx on the boat on channel 1, a receiver on the heli connected to another 2w tx on channel 8, and i will receive at ground with my 2 receivers connected to my oracle diversity. what do you think?
  8. Thanks guys!! thanks for your special suggest.. I think i will try to fit 3 tx's of 2W each, has 8 channel so i can choose to set: 1- 4-8 I will use 3 receivers on the heli, with 1-4-8 channels set, all the output connected to a QUAD, and the video out of the quad connected to the TX to ground. So now, i have to choose the TX for the video to send to ground, and also what kind of antennas to use: on the boats, on the heli for receivers, on the heli for the TX, and on the ground for receiver. I have also an oracle diversity, but as i understand i will use on ground only. or not? because the heli is always near to the boat, we can follow it everywhere..
  9. yes, we have to send the live video from 3 different boats. but we can choose wich one of that to send to ground. I think to use a 2,4ghz with a common 2db antenna from the boat, and to send the video from the heli to ground with a 900mhz TX. My customers are: www.class-1.com
  10. yes!! it's a real offshore powerboat, with pilots inside!! and we have also an helicopter. We need to send 3 different live videos..HOW TO? i found this website: www.rf-links.com
  11. from the heli to the ground can be around 3-4km..
  12. Hi to all!! i would like to send a live video from a bullet camera fitted on a powerboat. I can use an helicopter has a "bridge", so here are what i would like to do: POWERBOAT: 12v lead acid battery 7A+ bullet camera CCD 1/3" and a 2,4 ghz 8 channel 2W TX with a simple 2db circular omni antenna. HELICOPTER: 2 omni patch antennas, 1 oracle diversity, 2 receivers. So i can give the video signal to the broadcast digital transmitter fitted on the helicopter, wich is used to send the live video from the cameraman (sure, once at time!) and i can see a clear image on the ground. What do you think??? The helicopter will follow the boat, and the maximum distance (boat-helicopter) will be around 150meters maximum.
  13. here are my first test: http://vimeo.com/5311589 what do you think??
  14. i know Kirlah, but i think the specs are wrong! anyway, the RX antennas are good 1 patch and 1 yagi?
  15. Kilrah! here are a pic of my equipment. this is the TX: 2,4ghz 2W, there are 2 antennas available, the white one is much more longer, is better than the black one? and here are the RX antennas: what's the best cominations??
  16. thanks a lot!! so i'll test it with a simple antenna, should be more simple!! I think wich all is much more easy to do it, but i'll test it on thuesday afternoon. Thanks again!
  17. Thanks for your answer! I contacted a lot of different suppliers of broadcast Tx's, but nobody assure for a "fast moving object" use. As i told you before, i would like to use that tX's on bikes, cars, and now we are the official suppliers of the minicams for the world powerboats championship offshore: www.class-1.com What is the software to use to measure the RF level to the TX and RX?? Because i have only the LCD monitor to see the video! Anyway, sorry for my stupid question: but more db is not better than less db?? Is there a way also to send a live video (good quality) from a boat or airplane with internet???
  18. On 28th June there is an important event here in south Italy. An air show with a lot of important teams. I would like to fit an on board camera with a video TX. Here are what i would like to do: Airplane equipment: - 2 bullet cameras Sony 580 TV lines connected to a SS1000 chasecam video quad (for a picture in picture) - The video out (with PIP) connected to the video IN of my 2W 2,4gHz TX - Audio out from the interphone connected to the audio IN of the TX - The TX antenna will be a common "stilo" 3db, but i can fit a patch antenna 11db instead: what's your best suggest? Rx equipment: - n.1 directional 15db antenna - n.1 patch 15db omni antenna - n.1 Oracle diversity - n.2 receivers (same boundle with the TX!) - n.1 LCD monitor to see - n.1 video out is for the TV for live What do you think? the maximum distance is 1km, the minimum is 500mt. the place is in front of the sea. May i have to move up (around 10mt) the double antennas? Or is there a better way to send live video via internet? we have a lot of space for our equipment inside the airplane!!! If yes, what's your suggest? this equipment works well with RC planes, but i never tested before on a real airplane!!
  19. thanks a lot, but with a 1hz on a falcon wich flight at 300km/h with 8g of acceleration is not very accurate! VERY HARD to get right data! What's your suggest Kirlah?
  20. WOW!! thanks! but can i log the vertical speed also? but that unit is 1hz of update rate, not 5!
  21. Hi! i'm looking for a smaller speed logger, i need to record the vertical and ground speed, any suggest?
  22. Cool!!! i will buy some piece!! A question: sometimes i have another problem, i need a step down, from 14-16v (car-bike battery) to 12 or 11 volts (CCD camera), should be around 200-300mA: any suggest? i need a smallest and tiny product... bye!
  23. thanks for your answer, but i think that system is too heavy. I need a very smaller product because my equipment (camera+tx+battery) can't be over 17gr!
  24. yes, but there is a video on youtube where show this camera with a wideangle lens fitted..
