I was looking for a breadboard, and all I find is populated breadboards.
Some are hosting 2-3 completely different circuits on the same breadboard, and some circuits are as old as 5 years, or as old that I don't even remember how old they are. Should I clean out all the parts, should I give them a PCB and finish those projects, or should I just buy more breadboards?
I wonder how common is this. What's your oldest "temporary" circuit on a breadboard?
