The author of Instructables under the nickname macobt made an unpretentious, but practical breadboard from microchips. He took 28-pin sockets for this, but any will do, only they will be needed in a different amount.
And all because the master divides them in half, turning them into single-row ones:
Then it glues together as follows: five horizontal rows, a gap, then another five of the same rows. To set the width of the gap, he uses a microcircuit, but it is better to take three at once and place them on the left, in the middle and on the right. This will help when gluing both compression in the middle and diagonal skew.
On each of the halves of the future breadboard, vertical jumpers are soldered to the pins of the panels. You do not need to connect half of each other.
To repeat the configuration of the classic breadboard, he makes two tires: for the plus power and the common wire. Here, on each of the tires, it is necessary to solder one long horizontal jumper to the terminals of the panels.
All this the master glues to the plywood base (plastic is also suitable):
Homemade ready. Thanks to the classic configuration, it is suitable for assembly without any changes to the schemes previously modeled in the Fritzing program. Of course, when repeating, such a board can be scaled both horizontally and vertically, depending on the complexity of the circuits that you are going to debug on it.
