Where to get 12V from my computer?
Depending on how much power you need, the answer would vary, but the easiest place would probably be from the molex connector:
This is mostly a legacy connector that isn't used much in current comp …

How does a benchtop power supply measure and control current?
You most likely have a switching power supply that measures the current through a shunt resistor before the output voltage is measured - because the two are in series the power supply knows the output …

Why can't electronic systems use constant current power source and vary the voltage as power...
Lets imagine two outlets on a common house plug, fed by a constant current source somewhere further up the line, lets assume it's a 10A constant current source. When not in use the outlet needs to be …

Charging supercapacitors with Buck converter. Do I need to cut power once charge is reached?
One option would be to use a 5V schottky diode (and possibly a voltage divider if you want to charge above 5v) that opens a relay or similar, thus physically opening the circuit once the 5v is reached …
