How do you turn off or dim the status LEDs on Raspberry Pi?
I know some of them can be turned off in software, but the power LED and I think one other LED can't be turned off that way.
put your pi in a box so you dont have to look at the lights
Not if he wants to increase the resistance, for example if the existing resister is 1k, and he wants to bring it up to 15k, then he could leave the 1k there and add another 14k resistor(s).. or just add a 15k resistor because in this situation it dont fucking matter and nobody cares if its 15k or 16k.
For sistering resistors together, 1/Rt=1/R1 + 1/R2 + ... 1/Rn .
If 1/x=a and 1/y=a+n, and n>0, then x must be greater than y.
No matter how big a resistor you connect in parallel, the total resistance always goes down.
If you want the resistance to go up, you need to add a resistor in *series*, which means desoldering the existing resistor, which means you might as well just replace it rather than try to fit two resistors into a space made for one.
I was talking about putting them in series.
>fit two resistors into a space made for one
Cut the trace
sand or remove the coating in a method of your choice
apply resistor to new gap
I cant imagine why anyone would parallel resistors for a ~15ma led
Consider the traces on a board have very low resistance. Call them fire hoses.
Your resistor is a garden hose. Water still flows through, but it's much slower now. (nevermind the pressure didn't actually drop). If you attach another garden hose or anything else next to it, your cfm is still better.
This is also a good example of why the hydraulic analogy sucks and doesn't fucking help anyone in the long run
