Friends of Amateur Rocketry

<body> <h1>The Friends of Amateur Rocketry - High Power Rocketry<h1> <p> Friends of Amateur Rocketry is a licensed non-profit organization dedicated to further innovation in the field of experimental rocketry. F.A.R. conducts launches once a month at the F.A.R. Rocket Test Facility (RTF) in the Mojave desert near Cantil, CA. We currently hold a High Explosive Manufactures Permit (HEMP) and use it to manufacture and store High Power Experimental Rocket Engines at our desert site. Most of our volunteer employees hold a minimum of a "California Pyrotechnic Operator -- Rocket's third class" license, as well as all of them being employee possessors. F.A.R. encourages rocketry of all levels, from small estes rockets to large liquid propellent rockets. If interested in bringing out your rocket, or just coming out to watch one of F.A.R.'s periodic launches, please see our calendar of events. Questions or comments about this site?

F.A.R. is a supporter of the following organizations: Tripolli, National Association of Rocketry, Pacific Rocket Society, Reaction Research Society, and the Boy Scouts of America. Vote for our site!

Weather at FAR's Mojave Desert Based Launch Facility (Near Cantil, CA) project Description: For a senior electrical engineering design project at California State University Long Beach, a transmitter and receiver shall be designed, built, and implimented for real time video transmission from a solid fuel rocket. The design and building of the vehicle is included in the project. The rocket will utilize a reloadable aerotech K550 as its propulsion. A PK6 altimeter kit will be used as it's method of parachute deployment. Project Status: The engine mounting tube has been fabricated and attached into the aeroframe. Payload bay is partially completed. PK6 altimeter kit has been assembled and successfully tested. Fins have been cut and have been attached into the aeroframe. Bulkhead have been screwed in, and shock chord attached. We decided to go with DSB-SC AM as our type of signal modulation. To accomplish this, we are going to use a MC1496 chip for modulation in the transmitter. For the receiver, we are going to build a costas loop from a phase lock loop chip and a couple of the MC1496 chips to split the carrier from the incoming AM signal to be multiplied once again in a MC1496 chip for demodulation. We are also in the process of designing the amplifier output stage of the transmitter. The rocket is now fully painted. The 12 volt power source has been mounted in the payload bay. The camera housing is completed. We are currently researching upconversion and downconversion, since we are going to modulate/demodulate at 4Mhz in the MC1496 chip, we need to up/down convert the signal in the TX/RX to TX/RX the signal on a 445Mhz carrier. The RF oscillator is still in the design stages, however the amplitude modulating circuit has been fabricated and tested with a 3MHz carrier, the circuit has proven itself with good carrier suppression. Rocket is ready for test flight (w/out video camera) Well, the launch did not go to well. For starters, the PK6 altimeter was malfunctioning (was working fine during lab testing), and did not work. So, we changed over to a passive recovery system. Once we finally got the rocket in the air, the fins were ripped off due to the high acceleration sending the rocket into an unstable tumble. So this project is put on hold for now. We are still going to build the video TX & RX, but not fly it in a rocket yet. Probably will rebuild the rocket over the summer. <td align="center"><a href="http://far.pyroinnovations.com/"><font size="-2">Home<a /> <a href="http://far.pyroinnovations.com/blockhouses.html">Block Houses<a /> <a href="http://far.pyroinnovations.com/storage.html">Rocket Storage<a /> <a href="http://far.pyroinnovations.com/contactus.html">Contact Us<a /> <a href="http://far.pyroinnovations.com/calendar.html">Rocket Launch Calendar<a /> <a href="http://far.pyroinnovations.com/fpermits.html">Rocket Permits<a /> <a href="http://far.pyroinnovations.com/launchtowers.html">Launch Towers<a /> <a href="http://far.pyroinnovations.com/licensing.html">Rocket Licnesing<a /> <a href="http://far.pyroinnovations.com/links.html">Rocket Links<a /> <a href="http://far.pyroinnovations.com/rockethome.html">Rocket Home<a /> <a href="http://far.pyroinnovations.com/menu.html">rocket menu<a /> <a href="http://far.pyroinnovations.com/mythbusters.html">Mythbusters<a /> <a href="http://far.pyroinnovations.com/mythematches.html">Mythbusters Electric Matches<a /> <a href="http://far.pyroinnovations.com/restrooms.html">restrooms<a /> <a href="http://far.pyroinnovations.com/sponsorship.html">ROcket Sponsorship<a /> <a href="http://far.pyroinnovations.com/teststands.html">Rocket Test Stands<a /> <a href="http://far.pyroinnovations.com/vidrocket.html">Video Rocket<a /> <a href="http://far.pyroinnovations.com/watertower.html">Water Tower<a /> <a href="http://www.pyroinnovations.com/">Pyro Innovations<a /> <a href="http://www.statelifeguards.com/">Huntington State Lifeguards<a /> <a href="http://lacitylifeguards.pyroinnovations.com/">Los Angeles City Lifeguards<a /> </body>
