I found EM machines quite easy to get my head around 20 odd years ago.
Eventually, i got myself a FLASH that had been in a bush fire with the intention of getting it going. I remember emailing my dad in UK ( an electronics engineer) and asking him what the brown things are with a wire at each end.. theres columns of them... they were the 1W resistors that need to get replaced with 5W...LOL. I knew nothing about electronics.
Marvins site was up and free at the time and this was a great help although i still didnt know what i was doing.
Eventually, i took myself off to night school and did 3/4 of an electrical engineering diploma.. it taught me a lot and i loved the AC side of it all more than all the digital stuff.
10 years down the track and ive forgotten most of what i learned as i just dont use it... the AC i do.. but i dont have to K map anymore.. or use flip flops... design circuits using NAND gates only etc.
But now i read Marvins stuff and i go beyond it as i now have a better understanding of it all... i dont use his method of testing transistors.. i think it sucks to be honest.

I still know nothing.... but do know just enough now to work through a redundant TTL circuit... even a CMOS Zaccaria circuit ( these can hurt the head!).. can honestly say that i really did enjoy the TAFE course.. gave me an insight into the whole mathematics of the world.
I still have my notes and often read up on them to refresh the memory... so yes.... TAFE electrical engineering will give you the basic language
