Workshop with [[Dennis de Bel]] and [[Roel Roscam Abbing]] during [[HDSA 2016. If you are so smart why are you so poor|HDSA2016]]
A(n) (im)practical introduction to Hertzian space
It is time to descent from your Adobe cloud and descend onto the very physical Hertzian space of crystal oscillators, electromagnetic waves and solder smoke. Unlock the forgotten (im)potential of your $2000 macbook-facebook machines and reclaim the spectrum!
In this (non-AT approved, https://www.agentschaptelecom.nl/) workshop we will approach radio as a medium for (p2p) communication, power/control and (artistic) self-expression from a non-engineering point of view.
Among the topics covered are the transition from colonial radio to broadcast radio, pirate- and community radio, the utopian promise of the Web, the 'great digital switch over', modulating digital data over analog radio, encoding data into analog sound and how all of this fits in the power structures created by communication infrastructures.
Seizing the curriculum of R&D's low-end rich media publication as means of production, the participants will learn how to utilize cheap electronic components and household materials to create DIY network infrastructures, parallel to the black box modes of communications imposed on us now.
Looking beyond the usual "when the shit hits the fan" and "us versus them" scenarios, we will rather discuss the potentials, relevance and shortcomings of these DIY methodologies and how to apply it to your own practice.
Apply the given technology to your own practice and make it your own, possible directions:
- Fashion (wearable radio, em detection)
- Photography (radio photography? light==em waves, pcb developing)
- Apps (interface radio with smartphone as alternative, parallel network)
- Video art (compress video for transmission over radio waves > see: floppy films, sstv)
- Architecture / sculpture / fine art (treat the Hertzian space as the physical space it really is, em-blocker)
- Activism (all of the above ;), public space, debunking the myth of the aether as neutral medium)
- Graphic design/illustration publication (visualize the invisible, paint by numbers image transfer, PRINTed circuit boards)
- Food-design (uhf (microwave) cooking)
- Software defined radio - hackrf, limerf, rtl-sdr dongles > gain insight on wireless payment system, the police, wifi, ip cameras?
- Arduino (make a 'stupid-smart' radio)
- Raspberry pi (make autonomous (smart? stupid?) pirate radio station) interface it with the web.

Light to print guestbook <br>
We are sending a message by light. Place a laptop or other device in one corner of the room, send it by light (morse code). On the other side of the room a device will catch the light and will print the message on a paper.<br><br>
Automate the encoding of messages within image files then automate the extraction of the message for communication (Beth)<br><br>
MORSECODE GUESTBOOK (Joanna, Jennifer, Lucas) <br>
A morse code transmitted guestbook.
People can type in their message in text > it gets transmitted in morse code by a laser > then its received by a light sensor and translated back into text in the guestbook.

Sending Edgar Walthert's Sonic Waves typeface to an Oscilloscope.<br><br>
Micro radio (Oliver)<br>
Make a micro radio FM transmitter as proposed by Tetsuo Kogawa’s ‘A Micro Radio Manifesto’ that broadcasts below the legal FM spectrum. Tune multiple receivers (at a low volume) into the ‘station’ at different points inside the exhibition space all of which receive a broadcast of a simple, pre-recorded message: ‘I love you’ at 10 second intervals.<br><br>
Future as present (Marcel & Meike)<br>
Transmitting the Speed of information into the future as present as a reaction to action on questions and answers into knowledge of space-time-value production.<br><br>
Salt water antenna — proof of concept (Marta)<br>
The projet is create an antenna for a radio emitter made of a salt water circuit. The water circuit will be created with a hand water pump. <br>
A prototype for sailors in case of blackout.<br><br>
Radio Fishing - André, Jul, Hannah<br>
A fisherperson can visit the fishing pond (printer and radio receiver and laptop) using a fishing rod (phone connected to a radio transmitter). The fishing rod (phone connected to a radio transmitter) is visiting a web page which has a button letting you cast your hook into the pond. What will you catch? Wait and see what comes out of the fishing pond (printer)...<br><br>
