We build ever ything from the ground up\, including rocket airframes\, avionics hardwa re\, Linux flight computer software\, and communications systems. \;\ n \;\nOur current focus is testing a new airframe and building a new avionics system. We hope to launch with airframe only this spring/summe r in eastern Oregon\, and launch with the full avionics stack at BALLS 1 8 in the Blackrock Desert of Nevada on October 2-4. http://www.balls17. com/ \;\n \;\nhttp://psas.pdx.edu \;\n \;\nPSAS meets every Tuesday in the Computer Science lounge area of the Fourth Avenue Buildin g.

There are a few holes in the stack\, and as a commu nity we can get started on fundamental tools that will make things easie r for all of us. Some topics that came up in the session on Saturday.&# 13\;\n \;\nThe tools for programming FPGA's are all proprietary let's design an open source FPGA\, most of the patents are running out soon.& #13\;\n \;\nThere are open source 3d modeling tools\, but will they t ell you where the center of gravity of your amature rocket is? That's a n important thing to know when it passes mach 1. \;\n \;\nRadio is awesome. \;\n \;\nLook for an "\;Art of Community"\; bo ok\, or a tshirt that says "\;free as in freedom"\; amongst the dorkbot crowd to find the discussion. Don't worry if you miss this meet ing there isn't even a listserv up yet it's a meeting of convenience as many of the people from Saturday's discussion are going to be at DorkBot anyways. \n\nTags: hardware\, fpga\, rockets\, radio\, open source\n\n Imported from: http://calagator.org/events/1250459398 URL:http://etherpad.opensourcebridge.org/bcp4-7g0 SUMMARY:Open Source Hardware Users Group discussion LOCATION:Backspace: 115 NW 5th Ave\, Portland OR 97209 US SEQUENCE:1 END:VEVENT BEGIN:VEVENT CREATED;VALUE=DATE-TIME:20110607T205144Z DTEND;TZID=America/Los_Angeles;VALUE=DATE-TIME:20110607T190000 DTSTART;TZID=America/Los_Angeles;VALUE=DATE-TIME:20110607T180000 DTSTAMP;VALUE=DATE-TIME:20110607T205144Z LAST-MODIFIED;VALUE=DATE-TIME:20110607T210452Z UID:http://calagator.org/events/1250460695 DESCRIPTION:Portland State Aerospace Society (PSAS) is a volunteer group working on open source/open hardware amateur rockets.

Operating as sounding rockets\, fights r ange from 1000m to \;\nmore than 30km and are generally passively fin stabilized. Two of the \;\nsignificant challenges are deploying the recovery system components \;\n(generally parachutes) and providing t racking to locate the rocket after \;\nflight. Altus Metrum is a proj ect building hardware and software for \;\namateur rocketry\, and Alt OS is the suite of software running in the \;\nrocket avionics and on the ground to track and analyze the flight. \;\n \;\nThis talk wi ll discuss the unique system challenges presented by \;\nrocketry\, i ncluding high acceleration and speeds\, automatic control of \;\nexpl osives and other flammable materials and the wide range of technical \;\nskills of the participants. Included will be a presentation of the&# 13\;\nhardware components used in the system and how that has driven the \;\narchitecture of the AltOS flight software over four years of \;\ndevelopment. \;\n \;\nAbout the speaker: \;\n \;\nKeith Packard has been developing open source software since 1986\, focusing&# 13\;\non the X Window System since 1987\, designing and implementing lar ge parts of \;\nthe current implementation. He is currently a Princi pal Engineer with Intel's \;\nOpen Source Technology Center. Keith re ceived a Usenix Lifetime Achievement \;\naward in 1999 and sits on th e X.org foundation board. \;\n\n\nTags: rockets\n\nImported from: htt p://calagator.org/events/1250463954 URL:http://acm.pdx.edu/ SUMMARY:PSU Tech Talk: AltOS — Building Amateur Rocketry Software LOCATION:Portland State University FAB\, Room 86-09: 1900 SW Fourth Avenu e\, Portland Oregon 97201 US SEQUENCE:1 END:VEVENT BEGIN:VEVENT CREATED;VALUE=DATE-TIME:20150406T214542Z DTEND;TZID=America/Los_Angeles;VALUE=DATE-TIME:20150414T120000 DTSTART;TZID=America/Los_Angeles;VALUE=DATE-TIME:20150414T110000 DTSTAMP;VALUE=DATE-TIME:20150406T214542Z LAST-MODIFIED;VALUE=DATE-TIME:20150406T214542Z UID:http://calagator.org/events/1250468181 DESCRIPTION:abstract: \;\nPortland State Aerospace Society (PSAS) is a student aerospace engineering project at Portland State University.
