I always started with neatly coiled and bundled cables. One or two lab sessions over, they are all in tangled mess. Every few weeks, I spent my time to organize them again into neatly coiled and bundled cables. One or two lab sessions over....
Now, I just roll them up and toss them into a bin.
Seriously, I have bins for each type of cables, coax, test leads, power, usb, etc. They are all tossed into respective bins.
