3-D printers are an exciting technology, but another hot new tool may have just as significant of an impact in real-world projects.
Laser cutters were invented almost 50 years ago, but only became part of the home workshop in the past few years. In that short time, however, the maker community has embraced the machines with creative enthusiasm. While these 2-D cutters don’t produce sweet 3-D Yoda heads at the push of a button, they do bring impressive versatility to a wide range of applications.
If makers want to experiment with creative ideas that need to be produced with engineering-grade plastics, wood, leather, metal, or even food, laser cutters are often the only appropriate tool. Most laser cutters, and their beefy plasma cutter brethren, can produce objects much larger than standard 3-D prints in a much shorter time, and usually for a significantly lower cost. One forward-thinking cafe in Japan has even installed a cutting system so makers can laser cut parts while sipping a latte — whereas waiting for a 3-D printout would require a seven-course meal.
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
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.
