How often do you encounter situations where 74HC logic chips are useful? Any particular ones you use a lot? |
| sokoloff:
Most everything is moving/has moved to microcontrollers now, so the discrete logic chips are there mostly as microcontroller extenders in my use case. 595 (shift registers) are the only ones I've used a fair amount. Other than that, a smattering of inverters and line drivers/segment decoders. I'd stock some shift registers, maybe a few basic NAND, NOR, inverters, and plan to buy per-project on-demand anything else. The basic chips are mostly so you can teach yourself how TTL logic works. It's simple and generally robust, but there's no substitute for plugging things together and playing with it physically. |

He idiotically decided to start a bunch new threads to discuss specifics… |O |O |O :palm: --- End quote --- Come on, man, you don't have to resort to insults. I made *one* thread about general lab equipment (the big thread) and one about component parts (this thread). I hardly think it's idiotic to discuss specifics or try to segment/focus discussion in a field that is so vast and chock-full of material, especially when threads start to become top-heavy. I made another thread about flux application/cleaning but again that's again a more focused topic. --- End quote --- I'm getting annoyed because you've lost track of what info has been given to you and so re-ask in other threads, so the info is not only redundant but also fragmented. |

I haven't "lost track" of info -- I forgot maybe one or two things buried within random posts between all these pages, videos, websites, etc that I've been poring over. And again on this site we're talking a grand total of two threads here, so it's not "other threads." It's other thread. And each one has a very different focus. If such a small thing is enough to "annoy" you then don't read or respond to the thread -- no one is forcing you to. |

Tooki has vented his anger at me also, so you are not alone. Don't let him get under your skin. Don't start a war or this will get shut down. I will add your $1000 lab thread to my List C (see below). Is there a link in that thread to this one? How about make sure that all your threads are linked together so it will be easy to move around them. I think it would be best to add them to the first posts as an edit. If you have the energy, how about putting together a spreadsheet on what you end up with. Keep up the good work. |
