Finished most of the #ROES prototype board. Never have I been so excited to solder something, specifically the shield. After several years of hard work putting that shield on was a trophy! Its something that has collected dust for periods too and this is the second version I went full cycle on.
For those wondering this is the RF analogy board for an advanced highly percise SWR meter with Network-analyzer like capabilities built into an #Arduino shield. It measures a radio signals forward and reverse properties and compares them including complex impedance, complex reflection coefficient, SWR and much more. with two of them and a zigbee you can even operate one at your transmitter and the other at the antenna end and get both readouts in the shack. Cool stuff!
The yellow shielded wire wasnt working so I added a very tiny red wire instead. The final product wont need this and it may introduce some issues with the prototyping, lets hope not.
If you want to see more pictures of the project, including the GUI demo running or the earlier v1 version just check out the #ROES hashtag.
