Major automakers—along with upstarts such as Tesla and Uber—are racing to put self-driving cars on the road, leading to advances in enabling technologies such as laser range finders known as lidars. A lidar works like a hyperactive laser measure, scattering laser light in multiple directions to gather hundreds of thousands of measurements per second and build up a “point cloud” of spatial information. A computer processes these data to form a coherent picture of a vehicle’s surroundings.
Now a Pittsburgh-based start-up called Kaarta has integrated a lidar—more affordable and speedier these days, thanks to accelerated development by suppliers serving the auto industry—with a motion sensor, processor and seven-inch touch screen into a handheld device. Called the Contour, the device enables architects, builders and others to generate 3-D computer models of their surroundings on the fly as they walk through them, the company says. A camera on the device captures color data and maps them onto point clouds to render models in realistic hues. When loaded into standard computer-aided design (CAD) software, the models can then form the basis of building renovation plans or other projects.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
