Right. You can buy a smaller number for even less. The instructable
below shows how to control it with a Raspberry Pi.
https://www.instructables.com/id/Control-Sonoff-From-Raspberry-Pi/
But you're still going to need invention, and that's the magic that
bridges between what your packet program is doing on the Raspberry Pi
and the actions necessary to invoke the program to turn on the Sonoff.
You won't find that at Amazon Prime, but if you come to the meeting
tomorrow somebody might be able to find out more about how the packet
radio code works and suggest an approach.

Hmm.. Very pretty. Perhaps wishful thinking, but I was looking for
something closer to $50 that didn’t require new invention.
I like what you came up with. Nice shopping list too.
Have you ever seen a Sonoff WiFi Switch ? Amazon has 6 of these for
$65.

Hey Tadd,
If you’re talking 10 years ago time frame I’m guessing you’re
referring to the AmbientOrb. It was a device from an MIT
group/project that signaled the state of the weather, stock markets,
etc... Here’s an article about that device.
http://www.nbcnews.com/id/4758931/ns/technology_and_science-tech_and_gadgets/t/new-technology-relies-human-visual-system/
There have been many of these types of devices launched as
products/kickstarters/DIY projects since then, in various
incarnations. I’m sure you can find examples on Hackster.io
<http://Hackster.io>. Here’s one I built:

Also, here’s a more complete Rpi based tutorial:

The neopixel from Adafruit is great for this type of thing.

Hope this helps.
Cheers!

Once upon a time, possibly 10 years ago, I remember a device
which looked like a light fixture that sat on a desk. It lit up
in color, after it found some token or cue on the Internet. You
could use it to show a weather alert, or i a certain web page did
or did not responded to pings.
I never bought one. Now I need it for a ham radio project.
What I want to do is have a Raspberry PI that is doing ham radio
stuff (TARPN network communications, in this case) and have a
light, possibly a blinking LED, in the living room of my house,
that would indicate a message has been received via the ham radio
TARPN network. The Raspberry PI can have a file that is present
or missing, or filled with some value or another, and the
blinking light needs to use FTP or Telnet via WiFi to the
Raspberry PI and query the file. Alternatively I could have the
Raspberry PI issue a telnet message to turn the light on or off.
Something like this already exists. Does anybody know where to
get one?
Thanks!
