But this whole excercise is crazy. Adding 5 dollar in parts to get a 0.5 dollar regulator, that wasn't designed to go to 0 , to 0 ...
Just spend those 5 dollar on an dual opamp some resistor and a transistor and make a real power supply with adjustable current limit.
This is the most important lesson to take away from this exercise ==> it's never good, nor necessary, to over-engineer anything.
free_electron is absolutely correct here. When we have learned to make the right decisions, that are appropriate for the situation, only
then are we rightfully ENGINEERS.
As for ascii art : i like ascii art. Its easy to make , you dont need to muck about with saving as gif ( cant use jpeg because the compression messes it up sometimes ) or png , dont need to upload it to some shady imegahoster. You can just slap it in.
Ascii art doesn't actually bother me, I was poking fun at you. For me, I grew up on BBS's and USENET news, so I accept it. It is sometimes a little
more work to understand it, and I am sure its more work for you to create it, but it's just not necessary anymore given the tools that are
available today. (most of them free)
ASCII art survives a run though with Exchange server and outlook, while an attached image can be mangled, resized to zero or even substituted with a same sized item from the cache.............
I've never worked in an MS Exchange environment, so I can't comment on that . But I have also seen other mail servers mangle ASCII art just as easily as you say
exchange preserves it. So it probably goes both ways. I think if you're reading and posting on a web forum using an intermediary service, not browsing directly, then all bets are off anyways. And the forum seems to preserve most images that are uploaded, and can be uploaded directly, no need to host them on another server. The forum accepts png images just fine, see attached.
Cheers!
