An Artist with Open Source Satellite

For Artists, using sensors and microcontrollers have never been easier with open source hardware and software platforms. Cubesat program unprecedentedly lower entry barriers for running space programs. Artists have presented space art works even before Sputnik entered into space and are actually facilitating various space programs nowadays. So exploring the possibility of an open source satellite platform will not only give numerous freedom of expressions to artist but will also give meaningful insights to space engineers.

In the session, building plans based on existing open source platforms and some test results are presented including schematics, BOMs, CAD drawings, and etc. Entire flow of operating a satellite program by an artist is discussed with difficulties and corresponding solutions. And advantages of artist leading space programs based on open source platforms are reviewed, followed by concerns of sharing satellite technologies and how to mitigate them.

I want to have feasible yet physical means to explore my existence.

예술과 기술이 극한으로 향했을 때 그 둘의 차이가 궁금하다.
I want to question the difference between art and technology, esp. when both are pushed to the extreme.

극한 기술이 공유되고 의미없이 사용될 때 어떻게 될것인지 궁금하다.

Reliability as an Art – the strongest weapon in the world

The strongest weapon in the world

2006 Song Hojun | songhojun@gmail.com

U.S. attacked Iraq to find “weapons of mass destruction” with “weapons of mass destruction” and North Korea menaced neighbor countries and world using nuclear weapons. Still many countries firmly believe that their securities can only be protected by having stronger weapons and they invest a lot of money into killing machines. And we begin to wonder what it is all about to compete to develop instruments to threaten and kill people. One day, an idea of making strongest weapons to terminate the endless weapon competition around the world came into my head. Since violence begets violence, the strongest weapon in the world should not be in a form of violence. So I came up with an idea of building a machine that is unbreakable even by nuclear bomb and can store data of people’s wishes for peace and love. The strongest weapon in the world propagates people’s voice when certain events happen. This will be named as beautiful explosion. And those who spend their lives to develop machines to kill people and those who start war to make money using weapons will feel something if they see the strongest weapon in the world. And if these machines are built throughout the world and share voices of peace, this could act as the ultimate deterrent. And it could be called “weapons of mass happiness” as counterpart to WMD. In fact, building WMH-weapons of mass happiness is almost impossible. Even finding a material that can resist nuclear explosion is extremely difficult. But study and discussion to make the strongest weapon in the world are enough to give chances to reflect on what they did for those who build WMD and its advocates. 

In this article, first, ideal model of WMH is presented and how it can be implemented is discussed. Then, prototype of WMH is introduced along with importance of building a prototype to bring social issue. Last, issues for building a real WMH are discussed.

WMH is implemented as below:

Unbreakable exterior material- to be the strongest, it should endure current strongest weapon- a nuclear bomb’s explosion. And it should be waterproof to be installed outside.

Rugged interior material- interior materials like computer systems inside the WMH should persist to high radiation exposure and many harsh environmental factors like humidity, temperature changes, vibration, and etc. 

Storing beautiful messages- to store beautiful messages around the world through internet, WMH is built as a server. And to store messages on site, it has interface like a touch pad to recognize people’s writing and a camera to automatically capture beautiful moments that happens before WMH.

Beautiful explosion- when certain events happen, WMH is triggered to explode. Examples of triggering events are a war, a terror, a massacre, and etc. To propagate voices of peace and love, it needs to equip with communication devices. For normal time, it communicates with other using internet, but for war times, when all the internet infrastructures are destroyed, it uses satellite to transmit messages around the world. 

Self-generating- To be power independent, WMH uses solar panels to generate power. And to operate in a harsh environment for a long time, battery regulation circuit that’s almost as sophisticated as satellite system should be adopted. Solar panels are mounted inside the exterior material to be unbreakable. So a transparent super-strong exterior material is needed if solar panels are to be used.

 

As are presented above, building a WMH is an extremely challenging work. But the purpose of building a WMH is not to make money or anything practical, so a different approach can be taken to achieve WMH’s original goal. Anthony Dune and Fiona Raby define design noir as using and designing electro devices as social commentaries from their book, “Design Noir”. [1] In their book, many unpractical designs that are prototyped are introduced. And they claim that designs can generate many narratives in various social context when they are actually exists. The impact a design can have is greater when it is virtually exists than it is in conceptual drawing or writing, they said. For example, they built Faraday cage, where people get inside the cage to protect them from electo-magnetic waves that wander around the air. They asked many people to use them and received reports from them, and found out even non-operating but well-conceptualized prototype can generate narratives as much as final product could have. 

 

So the prototype of WMH is implemented to initiate the debate on weapon competition. As exterior material, duralumin is selected. A sphere, 850mm diameter, 20mm thickness, is casted to look strong. For interior material, industrial class computer with vibration isolator in duralumin case is used. To reduce the heat generated from power supply, fanless power supply is used. And to find out people’s movement and capture their moments, a fast speed camera and 2 IR lamps are used. For on-site interaction a receipt printer is mounted inside to print our messages for peace when it detects people’s movements. Along with building a prototype, writing a solid scenario is very important to deliver overall WMH’s goal. When existing prototype and the well written scenario are combined, WMH can generate many stories with the help of spectators’ imagination.

To use WMH as deterrent to war and weapon competition, a prototype is made. But to influence more, real WMH should be built. Building it by oneself is too much work and so open source project can be a solution for WMH building. So far most of the open source projects are software based. But for WMH, hardest parts are hardware based. So unlike software open source project, WMH cannot be built on-line. Still gathering information from various hobbyists, experts, artists, and anyone who’s interested in it is valuable. And to compensate on-line discussion, a conference can be held, where people get together, present their researches, and literally build WMH together. 

 

In the article, the strongest weapon in the world also known as weapon of mass happiness is presented. It is unbreakable, self-generating machine that is capable of storing people’s wishes for peace and love and transmitting them throughout the world. WMH is expected to bring up issues on endless weapon competition and killing. Although, it’s very hard to build a real WMH, a prototype and a good scenario can achieve similar goal. And when open source project for WMH is successful, a rough budget for real WMH can be projected to apply for a funding. Build something unpractical and use it as social commentary might be regarded as total insanity in capitalism. But we should know peace cannot be bought at any time.

Public bath and Nirvana

January 21st, 2009

어제 오랜만에, 1년만인것 같다.. , 목욕탕에 갔다.

24시간 하는 곳이 있어  딱딱해진 발바닦과 몸을 녹이러 갑자기 가게 되었다.

요즘에 양자론과 일반 상대성 이론을 통합시키는 모든것에 대한 이론 Theory Of Everything에 대해서 여러 사람들과 이야기 할 기회가 있었다. 목욕탕 가기전에도 뉴튼 2009년 1월호에서 다룬 파동에 관한 글을 보고 있었다.

온탕에 앉아 일어나는 거품을 보면서 한참을 앉아 있었다. 그러다 뉴튼에서 본 일러스트레이션 중 복잡한 무늬의 파도는 단순한 파동의 중첩된 형태에 대한 것이 생각났다. 워낙 파동에 관심이 많아 단순한 사인파의 중첩이 구형파를 만들어 낸다는 것은 익히 알고 있었지만 목욕탕에 가만히 앉아 흘러가는 파동들을 보자니 여러 생각들이 밀려왔다.

파동이라.. 원자, 전자도 파동으로 해석하는데.. 그럼 이런 가장 기본적인 것들이 조합이 나란 사람인가? 내 생각은 정말 내가 하는 생각인가? 

항상 생각하고 있었지만 이처럼 강하게 밀려올 줄은 몰랐다. 

지금 스위스에 위치한 CERN에서는 T.O.E.를 뒷받침하는 String Theory를 증명할 실험이 진행되고 있다. 만약 인류가 정말 미시와 거시 세계를 설명하는 4가지 힘을 한가지 이론으로 설명할 수 있다면… 나도 설명되나?

 

그럼 오히려 쉽게 삶에 대한 욕심을 포기할 수 있을까? 

과학을 통해 해탈하게 되는거야? 너무 물질적이고 분석적이잖아..

circuit board making workshop-arduino compatibles boards

January 11th, 2009


participants made board @ B05+B06 circuit board making workshop

Participants were able to build arduino-compatible board with li-polymer charger and step-up circuit in 5 days from drawing schematics to fabricating and assembling boards. it was challenging yet worth trying. 

while we’re building the boards in Korea, we figured out parts that are used in arduino needs to be localized so that more korean can use. 

So we open google site and upload all details like B.O.M.(bill of materials), where to buy and some alternatives for the parts.

new modified schematics will be uploaded continuously and other related projects will be proceeded in google workshop site. so keep looking.
