I’ve just joined the Forum so hope that this is the right place to ask my question! It's a question about relays, not semiconductors.
I retired twenty years ago (so my knowledge of modern components is pretty vague) but worked all my life on relay logic circuit design (mainly 12v, 24v, 110v DC circuits), however, I’m more than a bit rusty.
I did, on occasion, work on semi-conductor design but the industry I was in wanted mainly relays.
My son has asked me to design and build a NAND gate and an AND gate using just relays, with lights or whatever, to demonstrate how they work. It’s for pupils in his Computer/Electronic classes at the local school.
I, of course, said “Yes” (!?) – then realised just how rusty I’d become but I don’t like to admit it!
Could anyone, please, give me designs for the two gates and give me details of relays (and anything else) suggestd? If I could build these gates, satisfactorily, I would lie to my son for a few days and, then, tell him the truth – someone designed it for me – but, for those few days ....Glory, just like the old days!
Thanks,
John
