Look, Dad—They print wires now!

Pt 10814

Scientific American. Issue: Dec, 1954

Very thin copper—called “Electro-Sheet”—is bonded to a plastic laminate panel. On this copper sheet you print the wiring circuit you want with an ink that resists acid. Then you etch away the unwanted metal, leaving the pattern intact. This type of circuit is far superior to wires. It is accurate, compact and stable. Next you snap-fasten tube sockets and other parts in place and dip-solder the connections. To make a hundred electrical connections this way takes only a few seconds.

With printed wiring and other devices—such as transistors—electronic experts are concocting match-box-size hearing aids, vest pocket radios, more compact TV sets and portable electronic “brains.” They are speeding up the production of precision instruments vital in the operation of aircraft and control of guided missiles.


We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. Vest pocket radios!

  2. even cooler – Sargrove’s ECME stuff….

    http://blog.modernmechanix.com/2006/10/27/radio-robot-squirts-out-3-a-minute/?Qwd=./PopularScience/4-1948/radio_robot&Qif=radio_robot_1.jpg&Qiv=thumbs&Qis=XL#qdig

    of course we didn’t give him credit either.

    Sargrove was way ahead of his time “growing” curcuits…
    I worked as a research assistant right before Katrina in New Orleans with Self Assembled Nanowires… super atomic scale platinum – insanely low power consumption, nil resistance, crazy fast electron flow! A 9v might last until it naturally degrades!

    I love these articles! And I still do wire wrap – it’s like knitting to me.

  3. These sorts of modern marvels are all very well and good for the scientists and engineers working in their labs, but when will we the common folk get to enjoy the fruits of these futuristic discoveries?

    I want my portable electronic brain and compact TV set today, gosh darn it!

    😀

  4. OMG! This is going to change everything!

    Oh wait, it already did 🙂
