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.
Questions about my teammates projects
1. What theme are they investigating?
How to modify an image using sound, and how apply this transformation to ourselves?
2. What would be an appropriate question/challenge to answer in this project?
What's the connection between human appearance and sounds?
3. Name an interesting reference project that has yet to be mentioned (what does this work remind you of?)
Boris' project where an image is transmitted through sound and distorted by interference. (Cannot find it on the wiki)
4. In what context do you forsee the final result situated in (commercial product/service, gallery object/installation, public intervention, experimental publication….?
An interactive installation.
5. What weakness or threat should be urgently addressed?
If you want to augment someones appearance live then this could be challenging. (live mapping?)
6. What would you propose as a logical next step?
Talk to Boris
7. What might you be able to offer in terms of expertise/common interest that could be potentially useful for this project.
Any technical stuff concerning hardware I'd gladly look at.
8. How does/could the project connect with radio / electromagnetic spectrum?
This project is about sound and so is radio, but I don't see the link with the electromagnetic spectrum as of yet.
1. What theme are they investigating?
Remotely picking up signals from security camera's
2. What would be an appropriate question/challenge to answer in this project?
To define 'security' in a sense
3. Name an interesting reference project that has yet to be mentioned (what does this work remind you of?)
Stan and Stijn's insecam project from last year. (it's on their wiki's)
4. In what context do you forsee the final result situated in (commercial product/service, gallery object/installation, public intervention, experimental publication…. ?
A device (product) which you can take out in to the world and scan for camera's.
5. What weakness or threat should be urgently addressed?
Almost all security camera's use wifi.
6. What would you propose as a logical next step?
Proof of concept, conduct small scale tests to see if it works.
7. What might you be able to offer in terms of expertise/common interest that could be potentially useful for this project . Modifying your electronics.
8. How does/could the project connect with radio / electromagnetic spectrum?
You use an antenna to scan for signals/wifi
1. What theme are they investigating?
Non verbal communication through an object/installation
2. What would be an appropriate question/challenge to answer in this project?
How far can you stretch the definition of communication
3. Name an interesting reference project that has yet to be mentioned (what does this work remind you of?)
This reminds me of the 5th dimension scene from interstellar
4. In what context do you forsee the final result situated in (commercial product/service, gallery object/installation, public intervention, experimental publication…. ?
As an interactive installation
5. What weakness or threat should be urgently addressed?
How big is this going to be? Where are you going to build/store/display it?
6. What would you propose as a logical next step?
Proof of concept. Make an experience that demonstrates the effect you are trying to bring.
7. What might you be able to offer in terms of expertise/common interest that could be potentially useful for this project.
Anything hardware related, or conceptual layer.
8. How does/could the project connect with radio / electromagnetic spectrum?
Through the technology, but it could also have a conceptual connection.
