Jeffrey Kopcak - K8JTK
Ohio Section Technical Coordinator
The ARRL Technical Coordinator (TC) is a section-level official appointed by the Section Manager to coordinate all technical activities within the section.
For a section team to be effective in one of the most important arenas in Amateur Radio, technology, there must be a cadre of qualified, competent Technical Specialists (TS).
"Advancement of the radio art" is a profound obligation we incur under the rules of the FCC.
TSes help meet this obligation.
TS supports the TC in two main areas of responsibility:
Radio Frequency Interference and Technical Information.
Technical Specialist can specialize in certain specific technical areas, or can be generalists.

The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python...
...It's capable of doing everything you’d expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games. What’s more, the Raspberry Pi has the ability to interact with the outside world, and has been used in a wide array of digital maker projects.
from: What Is A Raspberry Pi?
Eben Upton, designer of the Raspberry Pi noticed the slide in skill levels while working at Cambridge University's Computer Laboratory in 2006.
Students applying to study computer science had far less experience than previous students.

Eben and his colleagues came up with the idea of creating a computer, that came with necessary tools, sold for $25, was robust enough to survive a children's book bag, that did interesting things, and drew people to use it.

The Raspberry Pi was designed to inspire children to take-up programming, but the vast majority of the £25 computers have been bought by adults.
"The reason we've sold so many of these (over a million) is largely is that they've sold to technology capable adults more than they've sold to kids," Upton said. "We think only 10-20%, maybe 30% of the ones we sold have ended up in the hands of kids."

d. randomly blinks Morse Code.

Interface the Pi with your own circuits!
Yep. Wait, what? Yeah, Windows!
"We've had people queuing up and saying they want Windows. I think there's a sense that 'you're a real PC' if you run Windows." -Upton
Not the desktop version of Windows. "Internet of Things" version of Windows 10 allowing access to Azure (cloud computing platform) services, along with other APIs.
Windows 10 IoT (Internet of Things) version completely free!
Not so fast.
The quickest way to get discouraged about something is to have no idea what you are going to do with it... AKA the "now what?" phenomenon.
Figure out a problem you want to solve FIRST before anything else.
Required to get started using the Pi.
Useful when using the Pi.
Two places for peripherals verified to work with the Raspberry Pi:
Of course, try any peripherals you can dig up first!
They say beginners should start with NOOBS. Truth is, NOOBS contains the Raspbian distribution with the option to download some other Linux distributions. I say skip it and download Raspbian.
sudo apt-get -y install libreoffice
Preloaded with Web (Epiphany). Alternatives:
sudo apt-get -y install gimp
Great for kids!
