Workshop 1
In the first workshop we made two coils for wireless energy transfer
Scanning for radio frequencies I mostly found:
- Digital signals
- Static interrupted by a high pitched signal
- Echo's of commercial radio
- Machine to machine communication
- More noise
Number stations
"A numbers station is a category of shortwave radio station characterized by broadcasts of formatted numbers, addressed to intelligence officers operating in foreign countries.[1] Most identified stations use speech synthesis to vocalize numbers, although digital modes, such as Phase-shift keying and Frequency-shift keying as well as Morse code transmissions are not uncommon. Most stations have set time schedules, or schedule patterns, however other stations appear to be broadcast at random times. Stations may or may not have set frequencies in the HF band." [Wikipedia]
I've emulated my own numbers station, the code is in hexadecimal numbers.
The code is: 43 6f 6d 6d 65 6e 63 65 20 6f 70 65 72 61 74 69 6f 6e 20 53 74 72 61 6e 67 65 6c 6f 76 65
Imaginary Radio
The nutshell receiver was conceived by Erik K. Hoorn in 2028 to listen to the frequencies affecting trees and plants. There is a direct relationship between microwave-induced structural and chemical modifications of plant species studied. These data collectively demonstrate that human-generated microwave pollution can potentially constitute a stress to the plants. The nutshell receiver is meant to listen in to frequencies surrounding plants and trees as to determine their safety. The receiver itself is of a provisional design meant to be sustainable. It is widely used in agriculture to meet increasing consumer demands.
Unravel Radio Marathon
For the unravel the radio marathon I was in the 'Radio Of Things' group. Our idea was to have two machines talk to each other in a way that's incomprehensible to humans. We wanted to have two harddrives react to each others electromagnetic frequencies. But it turned out that harddrives are very sophisticated pieces of technology, it was quite a challenge to be able to control the rpm of the disks. Luckily we got help from Tim and the MICA teachers, in the end we could control the rpm with a knob hooked up to an arduino. If we had another day we could have built the machines like we planned to, but now we only had one device "talking" and one "listening".
The "finished" installation:
Sketches Project Q10
For the next quarter I'm thinking of doing something with electromagnetic radiation.
I thought of a CRT Tv with electromagnets built in behind the screen, a console with turning knobs will let you manipulate individual magnets.
The screen will display a grid that will be warped by the magnets.
I've worked with a cathode ray tube once before, when I turned it in to an oscilloscope. I took the four wires coming out of the tube, two for the x axis, two for the y axis, and fed frequencies through an amplifier from my laptop. The frequencies made these lissajous shapes.
