Jason,
I started in computers without formal training.
First job was building CRT terminals with out a computer to connect.
Later learn hardware testing and the automated circuit testing with DEC PDP-8 paper tape and no disk.
After that used in circuit function tester for DEC PDP-11.
Then taught PDP-11 OS called RSX-11m which is much like X11 and then in 1995 Linux.
My name de plume Event Video is because of preference for TV and video over the computer in the box.
TechLab has Linux but no video so not as attractive as GamePup.
Once GamePup had a working video I began to like it but setting date was tedious so I added the RTC-5 from Mikroe
rather than build something with no skills to design and build hardware.
I started with sysgen on Linux in 1995 on terminal console then X11 so I prefer that operating system over MAC or Windows (by far).
I still plug things in like I know how to do but not designing circuits as is expected for embedded systems.
I also would learn by doing and never breadboard which again goes against the gist of embedded system learning.
As I progress I use various journaling tools like Slack and text files.
Here at Google Groups I can share my progress and maybe make a freind or two at the same level of skills.
The Midi music is still plug and play and my requirements are significantly beyond the small SBC systems for
expressing ideas.
I plan to use virtual reality head mounted stereo display so the Black fits that better with HDMI.
The GamePup will be the game controller when Wifi and bluetooth are plugged into both devices.
My favorite hardware was Sega with Dreamcast being easiest to play with display on the controller as I envision the GamePup for Android TV at Google Stadia (more users than Linux on Black).

Sonic ?
Maybe Boris will chase that Hedgehog in an Open Source Blender Movie !
I could imagine
3D printed and VR with Beagleboard AI embedded real time strategies as Midi theme songs play !
That's Cool Games Network and Event Video Multimedia in an open source hackerspace !
Just need the sources and the community !
