Why are they called breadboards?
Why are solderless protoboards called "breadboards"? I've used the term for decades but couldn't answer a student's question about the name.

What gauge of single strand wire works well with breadboards?
I bought some single strand wires hoping to prototype on the breadboards. Unfortunately it was too small to properly fit into the breadboard holes.
So my question is which gauge fits well on those small holes of breadboard?

How much current can Solderless Breadboards handle?
I'm working on a project with a few stepper motors. I want to breadboard them so I know the circuit works well before creating a physical PCB.
Each of the three motors is rated 2A, but I'll be prototyping with 1A (controled with driver chip) at 12V.…

What is the easiest way to connect a breadboard to a multimeter?
The test leads on my multimeter are too large to fit in the holes in my breadboard. How can I easily connect my multimeter to test voltage on my breadboard?

Wire broke off and stuck in a header
I'm working with an Arduino, and one of the stripped portions of the wire broke off at some point and managed to get pretty wedged into the 5V pin slot. Obviously, this wouldn't matter as much for a GPIO pin, but I sort of need to use the +5V…

Why does this comparator not output a square wave?
I have a 4.43MHz sinusoidal output from an IC that I want to convert to a TTL square wave to use as a clock. The signal has a DC offset of around 2.5V and has an amplitude of about 0.5V peak to peak.
I attempted to convert this to a 0-5V square wave…

Can you put a 120vac positive line into a breadboard?
Is there anything I need to know about putting a 120vac positive line in my breadboard? (Like, for example, if it's a bad idea to do that to begin with.) It will just be a christmas lights strand at less than a quarter amp. I will only be putting…

Breadboard computer
Is it possible to make a simple computer entirely with breadboards and basic electronic components? Is it feasible to, for example construct a scientific calculator in this way?

What causes dead spots in breadboards?
What causes "dead spots" in breadboards, where chips just don't work right? My guess is that the plastic or backing metal is warped, so the holes don't line up right, or the metal is somehow tarnished and nonconductive. In any case, can these be…

Microcontroller works on breadboard, but not on PCB (which is proven to be correct)
Summary: I have two circuits: One on breaboard and one on PCB. I have two Microcontrollers: A commercial one (pre programmed) and a personal one (with whom I try to recreate the commercial one). The commercial uC works in both circuits and my…

Can a switching power supply be built on a breadboard?
I'm toying with the idea of putting together a switching power supply (my first), using something like the LT1076-5 or the LM2576 controller ICs. These ICs have low external parts counts, and a relatively low switching frequency (56kHz-100kHz).…

What kind of rubber "melts" plastic?
I know this should probably be posted in a chemistry exchange, but I figured the parts are pretty standard electronics equipment that the question might be more relevant here.
So a couple of breadboards had been lying in a box with a rubbered…

Is there a good replacement for stripboard in the surface mount world?
More and more components I want to use are only available in surface mount packages.
I can either get a big collection of adapter boards for all flavors of SOIC/WFBGA/QDERP to 100 mil pin spacing, and keep using breadboard and stripboard, or I can…
