===== Scrying Workshop - TunedCity - Berlin July 2008 =====

After 3 days from a openly generous workshop, here below I try to collect some of the audio, pictures and g.p.s files that made part of my process following the schedule openly proposed by Martin Howse. ''[notes by Alejo Duque]''

=== EMF at T.v scrying bug Tower in AlexanderPlatz Berlin 2008 ===

On friday the 4th I had the chance to take the train at Schonhauser Alle, it took me 2 stops to have the Audio recorder and the first handmade hardware that used a coil as an antenna hokked together. I started recording while in the subway and had my G.P.S ready. When i finally got out the underground it was just in front the big Alexa shopping center. It took a while for the device to report my position but when i finally got one the trip continued. Below are some images from the place along with a 55min. audio track that can be paired with the place (latitude, lomgitude) via the timestamp in the G.P.S log.

=== G.P.S waypoints + Audio Recording ===

Listen here the audio recording from the walk around the area of AlexanderPlatzs that is also depicted below via an image og google earth generated on the log from a G.P.S that was also carried around: [[http://www.archive.org/details/EmfAtAlexanderPlatz]]

In case you want to follow the whole audio see also the waypoints, (image below) they have names according to the Minute in the timeline on the recorded soundtrack.

=== Devices ===

**After 3 days of workshop we manage to build 3 different boxes:**

__device #1__
the fisrt one a simple one based on an amplified coil running on 9volt batteries and allowing us to capture a wide range of "waves" including those from radio, there where moments when one could listen to radio stations, here is a short sample (Play LOUD!!): http://www.archive.org/details/EMF_radio_voices

__device #2__
our second box is an improvement to the design used in the first one, it offered an antenna and actually we soldered coaxial(?) cable following the calculation lambda=c/f for the case of 2.4ghz (wireless protocols a,b,g..) it gave us a 12.5cm cable. The sound file from: http://www.archive.org/details/EmfAtAlexanderPlatz was recorded before i soldered the antenna, i will like to test soon the device with the improvement to see how much gets captured or out.

here is a video using device#2 and a HSDPA broadband router: http://vimeo.com/1416877


Below you can see the first 2, one in the horizontal plane (#1) the other one in the vertical one (#2)

=== Antenna Calculator ===

2400000000 que equivalen a la freq de las redes wireless comunes 2.4ghz

300.000.000 meters/sec = c (speed of light) - la velocidad de la luz en metros por segundo

usamos esta formula para calcular el tamaño de la antenna:

lambda (wavelenght) = c/f (freq. in hertz) 

este seria el tamaño de la antenna, de los cuales 6.2cm esta descubiertos como se puede apreciar en la imagen
0.1249 meters = 12.5 cms -> wireless

=== Devices ===

__device #3__
this one is a little bit different since, instead of capturing waves, it produces them. In my view this is like a little EMF contaminator if that is possible to say. The reason why this one can be of good use lies behind the fact that its generated field serves in a more controlled way to arrive to wider area of waves hence sounds. Martin performed with it using a radio a 1.5km coil to conduct(?) the field and device#1 to amplify the captured waves.
