USB adaptors & DIY antenna = "Poor Man's WiFi" ?

wokfi/ (Italy)
Make 2.4GHz parabolic mesh dishes from cheap but sturdy Chinese cookware scoops & a USB WiFi adaptor! The largest so called
"WIFRY" or "WOKTENNA" (12"= 300mm diam) shows 12-15dB gain (enough for a LOS range extension to 3-5km),costs ~US$5 &
comes with a user friendly bamboo handle that suits WLAN fieldwork- if you can handle the curious stares! Neater boutique
versions may better appeal indoors. NB-unless you use more powerful USB adapters (such as ALFA & Senao offerings mentioned
below),weak USB adapter output power may mean you now hear more stronger APs than you can link back to ...

NB-the phrase "Poor Man" is not usually considered insulting, but indicates (possibly with a degree of DIY pride) a desire to "make it do, use it up, wear it
out" while laterally solving a problem. NZ Kiwi's are champions of such #8 wire ingenuity,with our electric fences a typical appropriate technology. Guess
our project even has East meets West cross cultural aspects- in the style of Kiwi Fruit evolving from Chinese Gooseberries !? 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.

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.

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

Flight Notes
For the first time I have successfully captured continuous footage of an entire flight
including boost, coast and 'chute deployment and some recovery - a very pleasing
result accomplished by using a helical antenna to boost the signal strenth at the ground
station. To cover momentary dropouts footage from a completely separate secondary
ground station using a yagi antenna was intercut after the flight and interestingly,
appears somewhat brighter and contains artifacts including reflections which create the
opportunity for further research.

Flight Notes
The normal speed clips show a complete flight including recovery - I make a guest
appearance as the rocket is returned to the primary downlink station. 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".

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

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).

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.

2.4 GHZ. High Gain Antenna Construction
Antenna for wireless networks
Here is a high gain antenna for 2.4 gHz wireless networks.
Here is how to build a high gain antenna for 2.4 gHz wireless networks. Several hams are
experimenting with these devices in an effort to build a network. It is sometimes referred to as
Hinternet or HSMM. My neighbor Jack, K8RT, and myself are also working on a neighborhood
wireless network. As a result of these efforts, I have come up with my own version of the classic
"cantenna" using 4 inch diameter aluminum dryer vent pipe, and a 4 to 6 inch pipe adapter. Although
the basic design is the same as other cantenna type antennas, the materials I ended up using are a bit
different. Preliminary results show a gain of 15 DBi. Not bad for less than $10 worth of materials!
A cross section diagram of the cantenna is below:
