[Discuss-gnuradio] re: Low cost hardware option
Hi, I am interested in helping out with making some new gnuradio hardware that is compatible with the USRP daughterboards. I worked with Matt doing CAD on the original gnuradio project hardware and have since then made lots more boards including a cyclone 3 board. Here is a possible hardware configuration: USB 3.0 transceiver IC or USB 3.0 microcontroller Altera Cyclone3 FPGA highspeed DAC/ADC If we use just a single channel ADC and DAC (ie half a USRP v1) then we can get away with a smaller/cheaper FPGA and have a cheaper/simpler board that can be paralleled if needed (ie. two boards hooked up to USB 3.0) Also we should pick a good open hardware license, here is one possibility I came across: http://freedomdefined.org/OSHW_draft I do all my work with Eagle CAD, and they sponsored a license for the gnuradio hardware project before, so we could look into getting a gnuradio specific license again or else consider using a free CAD program. Here's an eagle cad board I made with a cyclone3 FPGA on it designed to interface to a powersupply: http://rocketresearch.org/new/FPGA%20control%20module/FPGA%20control%20module%20PCB.png cheers, Jamie [Discuss-gnuradio] Low cost hardware option From: Euripedes Rocha Filho Subject: [Discuss-gnuradio] Low cost hardware option Date: Wed, 12 Jan 2011 19:03:17 -0200 Hi, i'm watching all discussion about poor students and the evil Mr Ettus who don't play like Santa Claus and whant to make some profit :). I'm also watching all topics and discussion regarding a low cost solution for use with GNURADIO. I guess we can have a cheap option to us and I'm very interested in work in such a solution. What I'm suggeting here is to take all people who want's to take the job and start a small project. I'm a embedded systems enthusiatic and was a starving student, now I'm a starving engineer, since I'm unemployed, that have some time to work on this project. The first question is: Ok, we need a low cost solution with some possible applications but what are the limits? ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio

I should say right off the bat that if I am involved to make this I would want to add a clause in the open source hardware license to not allow the hardware to be used for military applications. I think it is important to state this at the start before I would get involved working on a new gnu radio board. If people can live with that requirement I am happy to do the layout work. Obtaining critical mass with a community based, open source project is difficult enough -- you can see the very few examples that are successful and still alive after a couple of years. I'm not saying you're wrong or right, but if you make the path more narrow, your chances of success -- i.e. reaching milestones on the path and getting others to follow you -- decrease. Can you show some examples of other *successful* open source / open hardware projects where the license has this clause? Hi Jeff, All non-commercial use only clauses most likely restrict most military use, and these are quite common, and are far more restrictive than a non-military use only clause. I do follow what you are saying though, but its a choice like ethical investing, it makes economic sense to some people and seems foolish to some people. cheers, Jamie -Jeff ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Hi, Congratulations Jerry KD6JDJ as we discussed you will be receiving my USRP for your NOAA satellite project! To all those 30+ people who wrote me an email, thanks for sharing your project proposals, it was very nice to be able to read them all, I wish you all can have a free USRP! ;) cheers, Jamie _ Introducing Windows® phone. http://go.microsoft.com/?linkid=9708122___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] free USRP
Hi, I am giving my USRP v1 away, it is serial# 17 and works fine. Also included will be an RX and TX daughterboard as well as AC adapter and USB cord. If you want it please send me an email saying what you plan on using it for. Please only email me if you don't already have a USRP and otherwise cannot afford one! :) cheers, Jamie ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] cellular and satellite phones
Hi, I am currently working on a handheld device that uses a OEM cellular/GPS combo-module with a SIM card. Here is our project website: http://sourceforge.net/projects/m-pad/ Here is the quad-band cellular/GPS module we are using: http://www.telit.co.it/modulef.asp?famId=13famName=GM862-GPS%20Modem; There is also an FM radio IC on our device as well as a bluetooth+802.11g combo module: http://www.embeddedworks.net/newsite/WLAN/oem_sip_80211g.html; I would like to add also satellite phone capability to this device. However except for the Thuraya network, there don't seem to be any voice+data capable small OEM modules for the satellite networks, so I am curious if anyone has been working on a software satellite phone or if the protocol is publicly available? Soon I would like to integrate some or all of these RF modules into a hybrid software radio, but for now we are using the OEM modules. cheers, Jamie ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
