Design/Measurement System on Raspberry Pi

[pick]

I did a quick search and did not find anything. My old PC is in poor health and is near the end. I was tired of moving it around every time I needed to make measurements anyway. It seems to me the Raspberry Pi would make a good cheap platform to host REW as a test and measurement platform. I can't believe nobody is doing this. Has anyone done this? I think REW should work fine using the same USB audio interface I use on my PC. If running something like WineHQ, will the Dayton DATS system work properly? Otherwise, I think it's not too difficult to make a jig to measure TS parameters with REW, it's just a little less convenient.

REW also runs on Linux which is a better fit for the Raspberry Pi (but maybe not for you). In any case I'd go over to the official REW site (LINK). I'm sure you'll find people who have done REW on a Pi.

Yes, I agree REW should run properly on the Pi. I like the DATS system and would hope it could also be made to work. While REW supports Linux OS, I think DATS does not. If I can't get the Windows application to run on Linux, using something like WineHQ, I will need to build a jig and use the impedance measurement capability of REW.

For Raspberry pi, REW makes the most sense, however, Raspberry pi is a fairly low performance device so don't expect REW to be very snappy. Other consideration is that Raspberry pi can only supply 1.2A via USB, depending on your audio interface you may require external DC power in addition to the USB connection (a powered USB hub). Once you factor in the requirement for a monitor, KB and mouse, portability, use of other windows software for design, a cheap / used laptop makes a lot more sense for a measurement setup.

I'm all for keeping things simple, but I don't understand how using a Pi would be easier. Don't you still need KVM? Why not just a beater laptop?
