My Z3 3.0 has failed welds/crack in the trunk and the diff mount is cracked. How much would a welder charge me to weld the kit on if I do all the prep work?
I can do it myself, but I'm tired boss.
I've been playing with a RG40XXH and configuring it for my 5 year old's birthday present but there aren't any child screentime limitations built into the base system so I made my own. This is a service that can be activated by putting it into the /system/services/ directory and turning it on inside of system options.
Basic behavior:
Script keeps a background tally of screentime for the day. As time runs out, it changes the RGB stick colors from green to red, and then pulsing reg.
There's a voice that gives feedback every 15 minutes on how much time is left, then every minute, and every 15 seconds when you are less than 5 and 1 minute.
When time's up a 60 second shutdown timer starts, if you hit XYBA, it adds time to the timer.
If you don't, then the system shuts down.
Times reset the next calendar day.
I asked Gemini to annotate all code blocks so it shouldn't be too hard to figure out how to modify it to your children.
