Re: Pi4 won't boot with GPIO connections (lcd display) after wire mix up

Thanks for the great replies all. Just ordered a i2c level shifter today so that I can connect the lcd display using the backpack. You don't need that. You can connect it to GPIO02/pin#3 and GPIO03/pin#5 without any problems. https://pinout.xyz/pinout/i2c I can confirm this digging around I found m...

TL/DR

got me thinking:
any discussion here will have any (legal) bearing on the possible outcome?
does anybody participating in the discussion here posses an "absolute power" to steer or veer the course?

Re: Need help to buy new micro HDMI port for rp4 B

well... instead of getting the HDMI port fixed (no guarantee that it will work out well)
I suggest getting a new RPi4B instead and save all the trouble (and unwanted extra cost and anxiety)

then use the "old" one for headless RPi use.

that is what I will most likely do if the same happened to me.

Re: Dual Power Input

I'd probably DIY mine.....
inputs either strictly 5v sources
or wide range up to 36v

while at it, maybe I'll add another input source.... ;)

some basic circuits (at least 2 I remember) were already provided somewhere here in the forum.

Re: cron + rsync

first make a bash script for the rsync command you want to use
test it several times to see it it works as you intended.
then use cron to run that bash script at the time you want it to run.

its best to do the test on another separate setup
so as not to mess up your current and valued setup.

Re: bit of advice please - simply sense a doorbell press

oh another one:

if simply need to sense the movement of the button press:
put a micro-photoelectric sensor in the button...

but then again this will complicate things (need sensor amp, need to mod the switch, etc)

just replacing the button to DPST is still the cheapest and easiest to do.

when the button is pressed, it completed the circuit to ring the bell what you need to do is to sense that, there are several ways to do that 1. electromechanical relay method: 12v relay's coil across the chime 2. optocoupler method: with a current limiting resistor, also connected across the chime ...

@OP can you enumerate the procedure you followed to check if your RPi's analog jack is working with your earphones or not?

I just checked mine using my Bose SoundSport (wired) and it still works.
