Working with Dollar Tree Foam

In the latest Recomendo, Kevin Kelly wrote:

Foam core is super versatile making stuff. Together with hot glue you can make almost anything – doll houses, organizers, quick prototypes, kid’s constructions, models, displays, etc. The boards can be expensive at stationary stores. The cheapest source of foam board I know about are 20 x 30 x 3/16 inch sheets from the Dollar Tree store, at $1.25 per board. They are thin but sufficient and cheap.

Dollar Tree foam board sheets are especially coveted by tabletop gamers, dungeon crafters, diorama builders, “foamies” (foam plane builders), and other hobby crafters because the paper is so easily peeled away from the foam. All you have to do is spritz with alcohol and the paper comes right off, leaving you with a 3/16″ sheet of foam to work with.

In this video on DutchRC Adventures they show how to make curved shapes with the foam.


As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

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.
