Making a Utility Knife Mold for Leftover Casting Resin @JimmyDiResta
Jimmy DiResta had a cool idea. He created a mold for a disposable utility knife, so if he’s casting something and has a bunch of leftover resin, he can cast a disposable utility knife with the excess.
He’s planning on developing the mold into a product for sale, but you could obviously design, print, mold, and cast your own.
This project raises another great question. If you do a lot of casting and have leftover resin, what other tools and other castable objects can you create silicone molds for?
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.
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.
