Join Adafruit on Mastodon

Adafruit is on Mastodon, join in!

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, 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.

Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.

  1. It looks like they’re using a stencil of sorts to create the shape of the foam.

    A computer driven, dot matrix version of that would be cool.

  2. Video is all over the web, but with no attribution other than the IFA in Berlin. So who made it? They should step up and speak so the world can flock to their door! or post the plans so we can make our own!

    Maybe its just a screen printer meets dish soap?

    btw, love the Read This Resistor captcha!

  3. Looks cool. Would love to know more, plans, designs, etc.

  4. Its a great idea! I would like to see it expanded maybe instead of printing a “shape” in the horizontal axis maybe someone can figure out how to “print” in the vertical (think makerbot upside down with instead of one nozzle squirting out a single stream of goop a group of nozzles (of appropriate sizes and arranged) like injet printers and print a structure that builds upon itself, using the helium to “pull” the structure upward. I could see making 3d structures if the cells are small enough or certainly letters and or shapes similar to those seen above, it would just be customizable per print (you could make vertical words or sentences similar to those tacky vinyl “live love eat” script type wall hangings 😀 ) Arduino project anyone 😉


  5. Neat Idea! I would like to see it expanded upon. Instead of printing a specific shape how about making a printer that is customizable on the fly.

    The idea I have is a similar setup but instead of a stencil you use a arduino (or other microcontroler) and a bank of nozzles that either expel bubbles or just air(for a blank space) and that way you can make 3d shapes/structures or string letters together using a script font like with those tacky vinyl wall hanging like “live love eat”, etc. I think it could be done (might have to use a “tube system” that allows for bubble air bubble air bubble air like a genetic pump syringe thingy.


  6. Here is a follow up of the idea i was kind of thinking could be adapted to the foam printer in the way the prints are derived its for a long exposure picture, and painting with light with an ipad but how they derive the method to "build" the letter I think could be adapted to the foam printer if they used nozzles 😉

    whadda ya think?
