3D-Printed Circuit Boards, for solder-free printable electronics.
Given the schematic for a simple circuit, make it a real circuit with the base components, some conductive thread, and a 3D printer. No solder, no etching chemicals, no sending away for anything.
This Instructable is to serve as the how-to guide for a 3D-printed electronic circuit library implemented in OpenSCAD, 3D-PCB. I recreate the full replication process of a simple analog circuit of a blinking LED made from a few transistors, capacitors, and resistors, a single LED, and a AAA battery. I will review how to import the library, and use it to place components in OpenSCAD in a grid, and teach you the basic wrapping techniques for all the included features.
Also included is a more useful example of an LED flashlight.
