yeah...

forgot name, and I don't think I have an affiliation, basically having 
never worked in "the industry", and not currently having a job (and no 
real work experience).

also, where I am living, there is no real software industry stuff, and 
don't want to relocate (would prefer avoid densely populated areas). 
most of what is around where I am living is related to agriculture, and 
the manufacturing and oil industries.


last time I had a job was years ago, once briefly doing IT type stuff 
for a church. currently, most likely I will end up with a maintenance 
type job or similar (currently in college for "mechatronics", which is 
mostly focused on maintaining industrial machinery).

besides classes, IRL, I am also working on things like building custom 
electronics, mostly intended to build robots, but also working some on 
building a CNC milling machine, mostly to make some types of parts. some 
of my other parts are made on a 3D printer.


one of my more recent codec designs is intended mostly to stream video 
data from a robot back to the control program (running on a PC or laptop).

main robot I have now is basically a rolling cardboard box powered by a 
UPS battery.

I had intended to build a large quadrotor (mostly intended for lifting 
things), but this is currently stalled, as the propellers would be 
absurdly expensive, and I basically need to build a CNC mill to make 
them (and they are too big for the 3D printer and would likely need to 
be made of hardwood or similar).


my 3D game project exists, but it kind of sucked, and I never got any 
money from this.

yep.

yes, ok.
