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?
