Of all the things wrong with this, what sticks out to me how he seemed to be offended when you put down your boundaries. I feel sorry for your sister and i would share this with her. If he behaves like this with his own family, it doesn’t bode well outside of it. Yeah, perhaps replying wasn’t the best idea but i cannot put myself in your position vis-a-vis your state of mind at the time but it doesn’t take away the lack of appropriateness of his comments.
I like learning languages so with that in mind: German, Dutch, French, Swedish, Estonian, Russian, Afrikaans, Japanese, Mandarin, Korean, Irish and Latin. I don’t speak all of them thought.
Hard to say, but if the 5V natively to the machine is shot, I’d expect the unit to not work as its systems would depend on it. I assume you measured 5V in reference to the machines GND. Double check your meter against a known good 5V supply (your adapter).
If they both are power supplied, and have ground connected then what would you need the 5V connection for? Some devices that externally supply power can come with a protection diode to prevent looping power back to prevent the scenario you described but looks like that’s not needed. You would have to know the protocol used such as baudrate, bitlength, stopbits and parity. If you don’t have that info try common baudrates (115200), 8 bits, 1 stop, no parity.
Don’t remember the movie or show but on aired in Korea I saw they would blur out parts such as cigarettes as well as arm pits (male actor) and a chef’s knife (prop was being held with the actors intention to defend herself).
One day he was going on about Kiki, how she does things in a certain way and I kept him going by say how interesting it was. He then turned to me and asked “You know that Kiki isn’t real, right, I made her up?”. He doesn’t like lying or being lied to, so within that frame I guess he wanted me to confirm that it was just play.
Our child has one. Her name is Kiki and she lives on a farm where she drives her tractors in a village called Plamplams. She speaks also an imaginary language. It seems like she represents experience he lives through vicariously expressing some image he has on how he fits in this world. We as his parents have always encouraged him; it is wonderful how he develops such creative images.
Wouldn’t it be nice if the strength of relieve following such a task would outweigh the level of anxiety prior? At least that’s how it is for me. Happy for you that you have it scratched of your task list.
