Kickstarter: Red Pitaya Open Source Measurement and Control Tool

Red Pitaya open source measurement and control tool

Red Pitaya is raising money on Kickstarter for their open source measurement and control tool. The Red Pitaya tool replaces many expensive laboratory instruments for only a few hundred dollars. For instance, their tool can be use as an oscilloscope, spectrum analyzer, arbitrary signal generator, frequency response analyzer, and PID controller. The tool features a FPGA: Xilinx Zynq 7010 SoC (17,600 LUTs, 28k Logic Cells, 80 DSP slices).
