Questions on how to connect a PC to a washing machine (USB→TTL serial) - Divisions by zero

I need to connect a PC to my washing machine. The washing machine has a bank of pins labelled like this: * 0v * tx * rx * 5v The microcontroller is an ATmega32L, which has specs for the serial connection as follows: The Universal Synchronous and Asynchronous serial Receiver and Transmitter (USART) is a highly flexible serial communication device. The main features are: • Full Duplex Operation (Independent Serial Receive and Transmit Registers) • Asynchronous or Synchronous Operation • Master or Slave Clocked Synchronous Operation • High Resolution Baud Rate Generator • Supports Serial Frames with 5, 6, 7, 8, or 9 Data Bits and 1 or 2 Stop Bits • Odd or Even Parity Generation and Parity Check Supported by Hardware • Data OverRun Detection • Framing Error Detection • Noise Filtering Includes False Start Bit Detection and Digital Low Pass Filter • Three Separate Interrupts on TX Complete, TX Data Register Empty, and RX Complete • Multi-processor Communication Mode • Double Speed Asynchronous Communication Mode My USB to TTL serial adapter is apparently based on a ch340 chip. It looks almost exactly like the pic I attached, except mine does not have a crystal on it because I think the chip has an embedded clock. The important thing is the pins match my adapter. My knee-jerk thought was to connect it as follows: adapter → washing machine PCB gnd → 0v rxd → tx txd → rx 3v3 → (nothing) 5v → 5v (with s1 jumped to 5v on the adapter) Someone told me I should not connect 5v to 5v. I was assuming one connection needed 5v and the other supplied it, but I was told they are both supplying 5v, but not perfectly 5v, so the difference will strain something and cause damage. So how should I hook this up?

Anyone have any experience with eabud batteries? - Lemmy.World

Unfortunately I have excessive battery drain in the left earbud of my Sony WF XM4 set. I really like these earbuds and I am going to at least try to fix them. Has anyone here done any thing like this before? It makes sense, honestly, that the left runs down faster than the right, I use just the left at work all day everyday and only use the right at home maybe once a week. The left lasts 2.5 hours, the right lasts six or more.

How to get out of an uncomfortable egg culture situation with this one simple trick. Real talk: Calling people eggs is a violation of the egg prime directive, and is considered invalidating as you are trying to say that a person is not the gender they identify as, that their identity is invalid. Don’t call people eggs, like ever, it’s extremely uncool.
