Anyone who’s seen my old tips column on Make:, reads my weekly maker newsletter, or seen my tips articles in HackSpace knows that I have a bit of a thang for 1-2-3 blocks. These precision-milled hardened steel blocks are precisely 1″ x 2″ x 3″ and weigh exactly a pound. They were created for machinist use but have now been widely adopted across maker disciplines.
You can use them as shop weights, for measuring and aligning, to hold parts in place for gluing, and a thousand other uses. As we speak, I am using one to hold down some new foam pads I’ve just glued into the crossband of my JVC sound-isolated headphones.
In this Stumpy Nubs video, James shows some of the things he uses them for around the woodshop and he clears up a few misconceptions about them.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
