| 3M breadboards for cheap |

Looks like it's for a split (+/-) supply. |

Ah! Good thinking :) |
| tooki:
Split supplies are so common for some types of circuits, I wish they made breadboards with three buses on each side instead of two! |
| Richard Crowley:
ALL breadboards are made like that. The metal contact strips are NOT made in continuous lengths. They are made in discrete unit lengths. They are chopped into the groups of 5 for the vertical columns, and they are used "whole" for the horizontal (power bus) sections. The problem with this board is NOT how it is constructed. The problem is that it is not labeled properly to show where the bus segments are. I typically just solder jumper wires on the back side to make the horizontal nodes continuous. Tempest in a teapot. Nothing to see here. Move along. |

It was interrupted in the middle and caused a lot of trouble for us younglings... The only indication was a faint blue/red line on the component side - pretty easy to miss. --- Quote from: Richard Crowley on April 09, 2019, 12:54:52 pm ---Tempest in a teapot. Nothing to see here.
