Pretty cool. I would encourage people building these to get an Amateur
Radio License. https://www.arrl.org/ham-radio-licenses
It's pretty easy. Comparable to the written part of the DMV drivers test.
It makes sure everyone knows the rules of the road.
There are a few options:
Technician Class License - allows you to legally transmit on the 10 meter
band.
These are pretty easy. 35 multiple choice questions. Lots of online
resources for learning what you need to know.
General Class License - allows you to use the longer wavelength bands.
Check http://www.arrl.org/getting-licensed for more on how to get a license.

Yesterday a bunch of people got together to build up
their kits of 5 watt
digital radio transceivers!
These are HF ham radio transmitter/recievers that connect to a computer
over USB, and allow communication on digital modes on what we call low
frequencies these days (but they're also called Shortwave even though
they're now the longest waves we use). Technically one is supposed to have
a ham radio license to transmit on these frequencies, although anyone is
allowed to listen in.
This is the kit they were building:

We used the video microscope and all six soldering stations! It was the
most soldering happening at the same time in sudoroom in a long time. The
event will happen again on Wednesday.
