Using Bits of Left Over Molding Rubber to Volumize New Molds
Anyone who’s ever done any molding and casting knows how expensive molding rubber is and how aggravating it can be to be pouring a mold and come up short with your mold mix.
In this Robert Tolene video, he offers a tip I hadn’t heard of before for saving on molding materials. He calls it “dunkin’ chunkies” — cutting old molds pieces into small chunks and adding them into a new mold pour (in the voids where they won’t interfere with the object being molded).
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.
