Buses/Rails for Electronic ProjectsThis project aims to ease the task of doing the physical wiring for electronic projects. Sometimes difficulties arise when multiple wires have to connect to a single node. This is a useful way to create one or more buses or rails to make that kind of wiring a little easier.Using a blank PCB with multiple solder points tied together on the board, cut off a strip with as many of those rows as necessary. Typically they are in groups of five, though other configurations probably exist.A single strip, with a 5-pin male pin header soldered to it creates a bus that can accommodate up to five connections by directly soldering to the pin, wire wrapping or plugging in a female Dupont connector.If five isn't enough, a wider section of board with a column of rows of five works. Each additional row in the column must be connected to the row below with an ordinary PCB jumper, covering two pins but adding three more useable pins. For example, two rows yields 8 pins (10 pins, two of which are jumpered to tie the rows together), three rows gives 11, etc. The 3D printed part holds the cut off strip of PCB slightly angled from vertical. The part can be scaled in the slicer for the desired length. The cut off PCB strip is glued into the support piece, which can be glued to an enclosure or to a blank space on a project board.
