Lab note jottings below pix rather blog style,but arose during an educational WiFi workout & are intended to stimulate others into similar DIY investigation. The author- who first wrangled antenna as a radio ham in the 1960s- is a career educator with a flair for innovation, with extensive hands on WiFi experiences - www.manuka. orcon.net.nz has insights into "his" 2002 Lucent Orinoco PCMCIA driven Sardine Can Biquad antenna. LAB NOTES text below intended to document rather than entertain & enthuse- suggest you stay with images for the latter! 21 April 2004: The long awaited NetStumber 0.4 ( + PDA MiniStumb.) is just out ! ( www.netstumbler.com~1.2MB). Of course we've been trying all sorts of Wi-Fi cards to hand! Originally NS only favoured Orinoco PCMCIA, but the latest flavour IS talking to such cheapies as the popular NZ Dick Smith Electronics (DSE) NZ$69 USB thumb dongle adaptor (cat XH6822). This DSE sweetie is based on a ZyDAS chipset,& seems to perform almost as well as esteemed Orinocos under XP. Yah! Can't say things look bullet proof with NS 0.4 yet, but it's certainly a tempting way to go, since USB cables & active extenders are dirt cheap,& being just digital are lossless compared with COSTLY microwave coax cable & connectors. Will maybe do a roof top "sweet spot" trial from here in central Wellington, New Zealand & perhaps upload a NS file,but picked up a AP ~500m LOS away OK. 25th April 2004: Well - ANZAC day dawned fine here in Wellington (NZ), so in best military tradition we ran a few LOS(Line Of Sight) scouting trials, supporting the USB device on a broom handle tied to the roof,fed by ~5m of regular el cheapo USB cable from an XP laptop running the new NS 0.4 inside. As always LOS means just that at 2.4GHz, & assorted in line trees & buildings caused massive signal losses, so ~100m was all we managed while walking around the house/yard/street with a Dell Axim PDA & a Socket low power CF WiFi card. We'll give it a further trial tomorrow across the inner city Basin Reserve to Mt.Vic, where a standby Orinoco Sardine can biquad easily handles the 2km from work ( Massey University). Experiences however indicate already that such simple food can reflectors at each end look only good for ~2km LOS, & this USB receiver doesn't seem as sensitive as an esteemed PCMCIA Orinoco. Sniff ! That USB adaptors ceramic antenna may be the culprit - anyone fancy a "hack" & installation of say a Biquad ?! THOUGHT - fit this thumb at the focal point of a directive antenna? Quick trials with NS 0.4 showed useful gain with even a bare metal plate behind it. Perhaps the classic "Sardine can" biquad reflector? Simple metallic plates behind the unit gave significant weak signal boost, espec. when spacings were ~32mm ( which of course is 1/4 wavelength at 2.4GHz). With DIY dishes (each 15-20dB ?) then range increases to say 5-10km may result - dB maths says each 6dB gain will double the range. http://www.usbwifi.orcon.net.nz/ (3 of 11)02-Dec-07 8:12:04 AM Model Rocket Video Camera Australia - Aussie RocketCam Aussie RocketCam Model Rocket Onboard Inflight Video Camera link via 2.4GHz Microwave | Construction Details | Email: email michael Intrigued by the possibility of transmitting live video and audio from a model rocket to the ground? Me too. Scroll down for a list of clips or read on for the full Aussie RocketCam story. See the construction page for detailed descriptions and photographs of the construction of the onboard inflight video downlink system. Latest News: June 2007 I have some ATMEGA-8 AVR's with Arduino bootloader installed for sale. With the bare chips and a crystal or resonator you make a DIY Arduino runtime board on veroboard or a home made PCB, or build your Arduino up on a breadboard. For more information on Arduino here. May 2007 At the invitation of the Wireless Institute of Australia (WIA) I gave an afterdinner presentation on my model rocket video work at the WIA National Conference held in Parkes, NSW over the weekend of May 4 and 5 2007. The weekend included a tour of the CSIRO Parkes Observatory, also known as "The Dish". The Parkes radiotelescope participated in the relay of live television coverage of the 1969 NASA moon landing and is an active radioastronomy research instrument today. The Aussie Rocketcam transmits in the S-band and so a photo of me posing with the S-band feed for the Galileo deep-space probe to Jupiter that was fitted to the 64m Parkes antenna was irresistable. Galileo transmitted using 15W into a 7dBi antenna at 2.3 GHz. CCD camera technology (as used on the Rocketcam) was one of the spin-offs of the Galileo mission. Galileo's CCD camera had a resolution of 800x800 pixels. April 2007 RealTime Health a health video and animation site - have engaged me to compress their compelling health video content into Adobe Flash format. February 2007 Estes have jumped on the rocket video bandwagon with their Estes Oracle Digital Video E2X Rocket that records on-board video from a tiny CMOS camera. The camera is integrated into the plastic nosecone and points down in the same fashion that my camera does. The resolultion is 320x240 pixels and the .AVI video files are retrieved via USB. Presumably that means taking your laptop out to the flight paddock along with everything else in your flight box! While the video resolution of the Estes Oracle camera is lower than my CCD camera you don't have the losses associated with the analog transmission of the video back to the ground (earth) receiving station. Overall the view is very similar to the Aussie Rocketcam with a gllimpse of the rocket fuselage visible in the shot. The Oracle flies on D, E and F motors which is a nice way to keep the costs down. Check out the Estes Oracle at Estes Oracle at Amazon. March 2005 Added a discussion (below) on the degree of the doppler shift in the frequency of the transmitted 2.4GHz video signal as received on the ground. Oct 2004 The freecache system seems to have had a few problems lately so I am trying NYU's Coral CDN system to handle all the traffic from this site. Freecache has done a great job, including handling the Slashdotting of the Aussie Rocketcam site, and I hope http://holden.customer.netspace.net.au/rocketcam.html (1 of 8)02-Dec-07 8:13:05 AM Model Rocket Video Camera Australia - Aussie RocketCam they are able to overcome their technical problems shortly. April 2004 Altium have licensed Aussie RocketCam inflight footage for use in a promotional DVD for their Nexar FPGA development system. October 2003 Rex Ridenoure from Ecliptic Enterprises Corporation politely let me know that "RocketCam" is actually an Ecliptic Enterprises trademark. So for information regarding the Ecliptic Enterprises RocketCam(TM) systems for rockets, spacecraft and other remote platforms please see Ecliptic's website at www.eclipticenterprises.com. The Video System In September 2000 I purchased a microwave video transmitter / receiver system and a CCD bullet (or lipstick) camera from local electronics shop Radio Parts. These AV (audio-visual) transmitters are generally used for domestic video extension or security applications. The lipstick camera itself, which is housed in a stout cylindrical alloy case, would most commonly be employed in security monitoring application. Various cameras were auditioned and this particular camera, with a 1/3 inch Panasonic CCD chip, was selected for its image quality, dynamic range, high resolution and effective auto-exposure system. It is heavier, larger and less convenient to mount than the many alternative designs, but I am prepared to wear those disadvantages in order to obtain superior pictures. There is a lot of time and money involved in a rocket launch so you may as well go for the highest possible result. Examine the CCD cameras on display and compare the image quality of each, paying particular attention to video noise, level of detail (resolution) in the image and whether high contrast lighting conditions creates an exposure problem for the camera. Inflight rocket video downlinks are often accomplished using mirror systems (I believe the original Super-8 film format Estes Astrocam did this) however it was a design requirement for my Rocket Camera system that the camera have a direct view of the ground for maximum image quality. The Racewood transmitter I'm using can transmit on one of four frequencies in the 2.4Ghz (or 13cm) ISM band: ● ● ● ● Ch1 = 2413 MHz Ch2 = 2432 MHz CH3 = 2451 MHz CH4 = 2470 MHz. There is no standard for this however and other 2.4GHz transmitters available in http://holden.customer.netspace.net.au/rocketcam.html (2 of 8)02-Dec-07 8:13:05 AM Model Rocket Video Camera Australia - Aussie RocketCam Australia use slightly different frequencies that might be + or - 2MHz on each channel. Interoperability between systems is further complicated by the use of different frequencies for the audio-subcarrier and different numbers of audio channels: ie 1 for mono and 2 for stereo. Australian ACMA regulations limit the maximum power output of ISM band video senders to 10mW. A typical WiFi card puts out 30mw with some cards offering up to 200mW. Your mobile phone, cellphone or handphone (if you're in Malaysia) develops several Watts. Geek note: 2.4GHz AV senders use FM modulation for the vision carrier unlike "terrestrial" (ie not from a satellite) analog broadcast television which is AM modulated. Both systems use FM modulation for the audio. Proof of Concept I decided to use off-the-shelf video hardware so that I could quickly establish whether the concept of live video transmission from a model rocket was viable. At the time I didn't know a lot of radio theory and was concerned about issues such as: ● ● ● ● the limited range of this very low powered system (10mW output power) the effect that the rapid motion of the rocket might have on the signal ie doppler shift or other effects. (Update 25 March 2005). The magnitude of the doppler shift would cause at most a 2KHz drop in the received frequency. Obviously not a problem for a wideband mode like FM TV (could it be cause of problems for the narrower bandwidth AM audio-subcarrier?). This estimate of 2KHz of doppler shift is based on the antenna being situated at the launch location and the rocket travelling at 1000Km/h which is somewhat faster than the video rocket travels with its relatively heavy payload and low impulse mid-power rocket motors). For a discussion of doppler effects see Tony Langdon VK3JED's site. the attenuation of the signal cased by the airframe when it was between the transmitter and receiver as the rocket rolled during flight the impact of the changing orientation of the transmit antenna with respect to the receive antenna as the rocket arced over at apogee. (I was particularly keen to capture parachute ejection and was not disappointed once this was finally accomplished. I love watching the parachute unrolling and inflating in slow motion as the horizon drifts into view behind the rocket.) The deep blue of the sky suggests that the camera might have a polarising filter. The Launch Vehicle The mass and bulk of the components selected for the video link required the use of a larger http://holden.customer.netspace.net.au/rocketcam.html (3 of 8)02-Dec-07 8:13:05 AM Model Rocket Video Camera Australia - Aussie RocketCam rocket than could be safely launched with standard Estes A to D black powder motors. Fortunately at around the same time a friend imported several Aerotech ARCAS mid-powered rocket kits from an American online hobby retailer. The diameter of the ARCAS was just sufficient to house the circuit board from the transmitter once this was removed from its case (see the construction details page), and the bullet camera could be mounted outside the rocket, parallel with the body tube, pointed directly downward and protected via a streamlined nacelle carved from a block of balsa. The Results The original video signals obtained during early flights were of high qualty but contained extended dropouts and are not currently available on the site. The Research Goals section further down this page discusses this problem and what appears to be its solution. Watching the inflight model rocket video clips I suggest the launch to apogee clip in slow motion as a starting point ie serpentine5_slo (available in either QuickTime .mov or Windows Media .wmv format) as you can enjoy the flight details including the graceful parachute deployment. If you watch carefully you can also see the engine cap flying off as the motor fires. Extended footage of the rocket under canopy after parachute deployment is available in the long versions of each clip (ie serpentine5_slo_long.wmv) but may not be worth the extra download time for those with limited bandwidth. Under canopy the upper section of the rocket is spinning almost horizontally. However enthusiasts might enjoy stepping through the footage frame-by-frame for nice glimpses of the paddocks of country Victoria. If you have time to download more than one clip then the normal speed clips give a realistic sense of the incredible acceleration of a rocket flight and the howl as the rocket accelerates is amazing. Scrubbing backwards and forwards through the clip reveals interesting things about the flight of the rocket that you don't notice from the ground, and stepping frame-by-frame through the footage gives one time to linger over the details on the ground. Windows Media Player doesn't seem to allow stepping or scrubbing so I recommend QuickTime as the media playback client, so download QuickTime and then grab the QuickTime (.mov) versions of the clips because if you only ever play the footage straight through you're not getting the most out of it. An added bonus is that the slow-motion QuickTime movies are no larger than the normal versions. To create slow motion WMV's I've had to pad the movies out with duplicate http://holden.customer.netspace.net.au/rocketcam.html (4 of 8)02-Dec-07 8:13:05 AM Model Rocket Video Camera Australia - Aussie RocketCam frames.

It took three attempts to ignite this old White Lighting reload and the slow motion clips are particularly cool as we see one of Troy's "special" igniters finally do the trick. The primary downlink station was running a Mini-kits EME103 20dB 2.4GHz pre-amplifier. This did not make any obvious difference to the range of the system - it has been suggested this is because I am already on the receiver's "noise floor". Email Address (Comments welcome) email michael Research Goals Capture continuous footage by experimentation with transmit and receive antennas, ensuring there are no intermittent connections, looking at transmit amplifiers or receive preamps and investigating whether the camcorder being used to record the output from http://holden.customer.netspace.net.au/rocketcam.html (6 of 8)02-Dec-07 8:13:05 AM Model Rocket Video Camera Australia - Aussie RocketCam the receiver is taking longer than one might expect to recover from a momentary loss of signal. Note June 2002: This goal has been attained through higher gain helical and yagi receive antennas. Although the signal loss in earlier flights appeared to coincide with burnout, suggesting an intermittent electrical connection associated with negative g this does not, in fact, appear to be the case. Instead it would seem that the signal was simply lost as the pattern from the two omni-directional antennae were no longer coincident. Once the rocket had attained a certain height the vertically polarised receive antenna was effectively in a null underneath the vertically polarised transmit antenna. This may also explain why the signal was regained at apogee. Other things to sort out ● ● ● Why the audio is still dropping out occasionally - perhaps the problem is not electrical at all but the mechanical effect of acceleration on the electret microphone. Why no audio at all was recorded by the second ground station - does it use a different audio subcarrier ? Why the transmitter stops transmitting when sitting on the launch pad and need a thump to get it working again (does it actually drop out or does the A/D converter or DV codec in the camcorder go to sleep ? (I need to build a VDA to check this or incorporate an S-meter into the receiver). Model Rocket Video Links and Thanks ● ● ● ● ● Thanks to Darren for the loan of his helical antenna and to Jason Hecker for his helical antenna design. Thanks to Julian for his invaluable help including aiming the helical at the rocket during flight. (Darren, Jason and Julian and myself are members of Melbourne Wireless, a group who, like many others around the world, are building a community broadband wireless network using 802.11b IEEE standard WiFi equipment which shares the same unlicensed region of the spectrum as this particular low-powered video transmitter). Additional inflight footage was recorded independently by David Boyd, a fellow Tripoli Australia member and his team using a 12dBi yagi antenna and their own microwave band video receiver and camcorder. David's recordings were intercut with mine using Adobe Premiere and the resulting clips were compressed in Media Cleaner Pro 5. The Aerotech Arcas launch vehicle was supplied and constructed by Dave and Cath. I found Terry A.
