Open source satellites

Thursday, May 6th, 2010


After three years of research and one year of experience as a satellite engineer, Song Hojun has found that it is possible to launch and operate a personal satellite at a fairly reasonable price. In addition, he has for the past five years been exploring ways to integrate the concept of a personal satellite project into cultural contexts and into his artistic practice.

All the satellite-related systems (except for the rocket to launch it) are DIY programs — designed so that regular people may also have the chance of developing and eventually launching their own.

Song have presented this system and how it works at the Machine Project, Los Angeles on 2010, 25th April.

For the people who want to study or getting a clearer picture of the involving mechanisme, they can download Song’s book from Google Books here.

Open Source Lion-Tracking Collars In the Works

Thursday, April 15th, 2010


Want to help save some lions in Kenya? Well, help these guys make some open source lion-tracking collars, complete with GPS and GSM on board.

Lions are not doing too well in Kenya, with only 2,000 or so left. Two groups called Lion Guardians and Living with Lions are dedicated to studying and saving the diminished lion population. In order to help them out, Justin Downs of Brooklyn’s GRND Lab built them a solar-powered treehouse last year. Now, he’s working on some of the aforementioned collars to help them track the lions.

He’s looking for donations on Kickstarter for the project now, so if your passions create a Venn diagram between open-source hardware and lions, well, here you go.

Open Source Zigbee Stack

Sunday, August 24th, 2008 Many RF technologies are competing on 2.4GHz. The WLAN and Bluetooth have dominated the consumer wireless market. Zigbee is getting hotter in the mesh network application as well. More and more chip vendors have released their new products for Zigbee. TI/Chipcon, Freescale, Microchip, Atmel, Slilabs and Amber are active in Zigbee market. Zigbee is a wireless mesh network; its initial investment is much higher than an individual microcontroller based application. A serious development on a Zigbee project must include ICs, the Zigbee stack, the application software in the network nodes and the network administration software for the control terminals.

In September 2007, TI announced that it opened its fully functional Zigbee stack, Z-stack to the developers. Every registered developer can download the source code from the web site for free of charge. It was a shock to this market. Before this open source promotion, the quotation of this certificated Z-Stack source code was 100K USD.

Z-Stack can be downloaded in two formats: a “core” stack installer or a “full” stack installer. The “core” installer is targeted to experienced Z-Stack users who only need updated library and source files. The “full” installer is intended for users who would like additional application examples.
