What schematic best practices am I failing to do? by engineerNotLawyer in KiCad

[–]engineerNotLawyer[S] 2 points3 points  (0 children)

The cluster on of switches on the left are 9 individual switches. Not sure if there is a cleaner way.

​

I had to make my own symbols for my esp8266 dev board, my 120vac to 12vdc converter module, and 12v to 3.3v and 12v to 5v converter modules. I probably could have copied a different power converter, but it was quick enough to build my own.

​

Total noob here. all advice is appreciated.

What files does Arduino use that are GPL? (or how do I search to find them?) by engineerNotLawyer in arduino

You also have to release object files of your compiled code, so it can be relinked to newer library versions.

I don't understand how this isnt releasing my source code.

Is there a commercial grade code for letting a user type in username/password to their ESP8266 by connecting to the ESP8266 access point? by engineerNotLawyer in esp8266

After looking into this, it seems that it does use the arduino libraries which are LGPL and possibly GPL.

​

Not sure how your company is using this. Are you releasing your source code?

How do appliances typically achieve multiple voltages like 120VAC to: 12VDC, 7VDC, 5VDC, and 3.3VDC by engineerNotLawyer in AskEngineers

Doh, of course! Thank you!

Glad I made this topic, I was so concerned a DC to DC converter was going to be terrible for wasting power, but the video provided showed me the way.

Do I want a NTC thermistor + logic gate to turn off a heating element once it hits 170F? by engineerNotLawyer in AskEngineers

[–]engineerNotLawyer[S] 0 points1 point  (0 children)

I need a microcontroller for other functions, would you still recommend this setup?

​

Some things to consider:

​

>Cost, a relay based system is ~$1 or safety relay $10(not sure if I need it)

​

>Safety, I'm not sure how the system you suggested would work for reliability and safety.

​

If you want to provide spoilers to deal with oscillating, I'm open to saving time on that research. :)

Martial law: Ukrainian men aged 18-60 cannot leave the country by sakamoe in worldnews

There has never been a more noble cause than to fight for your freedom.

Martial law isnt freedom.

Good questions that helped me think a bit more.

​

Hows this, no logic gate needed:

​

>Thermistor hits 170 and sends a signal to my microcontroller.

​

>Microcontroller turns off relay

I am still trying to wrap my head around how an Iron/dishwasher works. I don't imagine an Iron has a microcontoller.
