A few comments:
- the kit could be done for less that $100, all though I see your point. Most have a decent USB power source and SDR can be found cheaper.
- the RasPI case, IMO, could be optional.
I would use the Linux commands to have piware installed on the RasPI vs downloading and saving it to a computer. The Linux commands on the piware install page worked great on my two installs and it seems a heck of a lot less complicated than involving a PC or Mac.
More important, as a person that recently set up piaware, the challenge is not with the piaware install. The challenge is getting dump1060 running with the correct option switches and verifing it is running correctly. For example, I had everything set up, but is took this forum to make me realize I needed the --net switch.
So, my recommendation would be to add some install commands after the “do you already have dump1090 running on the RasPI” question and explain some of the switch options that may be important. Also maybe a statement or two about what each column in dump1090 means just to educate the new user as to what to expect.
Also, two quick dump1090 confirmation tests I learned on my own:
- dump1090 is running fine if the cursor on the top far right is ‘twirling’
- dump1090 is running fine is you can URL to port 8080 and see a map.
Again, once dump1090 (for me) was the challenge. The piaware part was a snap/well documented.
