Very nice work. I love hardware based projects. Regarding the FPGA isn't the Lattice ECP5 FPGA too costly for a personal project?

> The end project is a low cost combination signal generator / oscilloscope for aligning antique radios that I eventually want to sell.

What do you mean by aligning antique radio? Could you please explain a little bit on this?

Are you using lattice tools to build or open source tools?

Also is it similar to Red Pitaya board?
