Likely the two most important for DIYers are the easily-modifiable breadboard and resilient yet still versatile perfboard. Taking a design from schematic to breadboard, and subsequently perfboard, is a vital process to the electronics maker – learn it, live it, love it! © Adafruit Industries https://learn.adafruit.com/collins-lab-breadboards-and-perfboards Page 3 of 14 Transcript Circuit schematics are very nice things … all these components floating in a lovely two-dimensional world with ideal placement & perfect connections … a nice idea. But eventually … we have to make them real. And in reality, a circuit usually exists on some type of circuit board - like say, a breadboard for example. Breadboards offer the most flexible way to assemble a circuit - build it, change it, scrap it, start over - all good, breadboard don’t mind at all. And that’s because it doesn’t require any soldering. © Adafruit Industries https://learn.adafruit.com/collins-lab-breadboards-and-perfboards Page 4 of 14 Beneath all those holes, a breadboard houses an army of springy metal clips which hold component leads in place while providing electrical connections between them. … though you may want to avoid taking one apart. When we place a component on a breadboard, we’re essentially wiring it into one of those internally connected rows.

  • The Technology of Wire Wrapping

SOLLARS "[he Plessey Company Limited, Allen Clark Research Centre, Northants, U.K. (Received October 27, 1973; in final form December 6, 1973) The basic technique of wire wrapping is now well established as a simple and reliable method for joining conductor wires in a permanent, though easily replaceable, manner to more massive terminals. This paper describes the mechanical and the metallurgical basis of the joining technique and outlines the advantages. The scope of the technique as it has developed up to the present day is discussed in terms of the ranges of wrapping terminals and wrapping wires used and the types of wrapped joint that have been evolved. Finally the tools available for wire wrapping are briefly reviewed with particular emphasis on the wrapping bit. THE MECHANICAL BASIS OF THE WRAPPED at various temperatures. Extrapolation techniques can JOINT be used to predict the long term stress relaxation behaviour at room temperature using results obtained The mechanical basis of the wire wrapped joint was by accelerating the process at elevated temperature. investigated very extensively by workers at Bell The elastic stress level in the joint is of importance Telephone Laboratories 20 years ago.
