Academic quals zero. Failed 4 years of highschool.
Experience, radio tech in the 60/70s, first CAM system I worked on cost $1M had no hard drive and 8k core memory, first CAD system I worked on cost $.5M had a 2Mb hard drive.
Inventions, none commercialized, noise cancelling rally car intercom in 1969, programable car odometer in 1971, new approach to website design in late 90s.
Had/have the pleasure of working with two young world class programmers covering many languages. 40 years, I may have contributed some small ideas, in my dreams.
Interests, many, read Rachel Carson back in 1964, politics, cars, tuning, suspension and in general. Electronics before and after computers, software, not a coder, but did devise a spreadsheet using basic in early 80s, used excel for a national survey in 80s and access for an accounting system for a university.
Recently, growing stuff, including trout and berries, solar heating systems and solar power, iot but mostly researching, only now have I some time to get involved. Decided very recently I want to understand and really become expert with can bus and mqtt, I think I can do it with some help. (why, it's a little different to doing everything with wifi)
I have to say, again, I am interested in this site because of Bill's efforts, rarely do you find something so good. For different reasons, Bill and Boian Mitov, have made this effort a pleasure. THANK YOU.

CAN bus is cool as is MQTT!
We are all trying to help each other in various technologies...
It all starts with asking questions 😉
Cheers.
Damn you are even older than me 🙂 Welcome aboard!
Yes questions, thanks for asking.
I need to learn a little more, but am trying to flesh out some options.
Hard to ask questions when the knowledge level is pretty ordinary.
My experience with logging cars, updating tunes and a lot of reading on the excellent romraider site convinced me to persue getting a handle on a diffivult subject.
The very lite arduino environment makes me think the code will have to be smart, a challenge. I am trying to get a handle on Visuino at the moment.
Probably mqtt is not ideal, my objective is no external connections, no wifi.
(I know the "homeassistant" world has done everything I am thinking of, but I want to take a fresh approach.)
My thinking is a data logger on a pretty good singleboard computer as controller, I have an odroid sbc that can run android or linux so will start with that.
Eventually a graphical user interface to display data and manage parameters.
The nodes will be the simplest possible, canbus modem, micro controller, sensors and control switches ssr, relays etc. Nodes will do some local control decision making with the central controller managing heavier needs. Costs will be minimal.
Any thoughts on the the type of program to use for the controller or nodes would be welcome.
This is not a commercial project, pushing 73 this year, it's purely for fun and mental health.
