My Bluetooth Sniper Weapon
Summary
This is my version of the the Bluetooth Sniper weapon,
it features a medium sized YAGI antenna combined with a 10* magnification
scope and a metalised parabolic which may bundle the Bluetooth signal,
thus further enhancing the range. The interior is made from a Linksys
USB dongle soldered to the YAGI
antenna and to a USB
cable contractor
USB Dongle
The soldering process was a mess, I never soldered in my life
and hence I wasted a dongle trying. The Antenna hole is really thin, so instead
of poking the cable through the hole I soldered it directly on to existing
solder by lightly heating it up indirectly through the cable.
Anyway after several hours of work trying different cable
combinations and temperatures I succeeded. Great care should be taken not to
heat up the chip to much while soldering. (Hint: I used Aluminum foil to shield
it from excess heat)
After I successfully soldered it to some coax
cable, I closed the USB dongle and glued the cable in place using a hot
glue gun.
YAGI Antenna
Then modifications to
the YAGI had to be made, initially the YAGI
Antenna has the cable ending come
out of the side of the antenna, I wanted the end of the cable to come
out at the horizontal end of the Antenna. The goal was that the cable directly
enters the gun through the parabola without any cable visible. This was
done by simply bending the cable inside, drilling a hole here and there
and have it go out at the end of the antenna.
Combining YAGI and the Bluetooned Dongle
Now both had to be interconnected while taking care that the
cable, dongle and USB connector fit inside the plastic molding of the main
part the gun. The tricky part here was that the Yagi, the parabola, the gun,
the cables and the dongle had to align correctly for the whole to fit.
The Parabola
The parabola was clear plastic and had to be metalised in order to correctly reflect the bluetooth wavelength, I used 99% zinc spray to create a flat metal surface. Bluetooth uses a different part of the electromagnetic spectrum with quite different signal propagation characteristics then Wifi. The signal wavelength used with Bluetooth communication (about 12.5 cm, at its associated frequency of 2.4GHz). At this wavelength, radio frequency (RF) communications can penetrate many non metallic obstacles.
The Scope
The scope gives a 10 fold magnification directly through the parabola, the lens itself can be accommodated to compensate for vision problems.

am currently working as a Security Engineer and Penetration Tester for "some
company" in Luxembourg.
On these pages i'll treat everything I enjoy and I get in touch with. This
may not be strictly related to security but may also touch parts of my personal
life.
Speaking of which, on the left that's me, I am 26 and have been involved in
the security field since I was 16. I do sports, Fitness and Body Building,
I hack various things such as cars, electronics...
