The thing about books is that they’re not very much good when they’re closed and wedged into a shelf. At the same time, no sensible curator would let you put your grubby little mitts on a 250-year-old treasure. So, starting in 2013, the British Library began scanning thousands of books from the 17th, 18th and 19th Centuries, and has now made all of the images contained within them free to download (they’re all well out of copyright).
The curation is a bit all over the place, but there are some loose categories. In “Cycling,” for instance, you can see strange inventions of yore like a bicycle that uses a crankshaft and bevel gears rather than a chain, and another that features oddly asymmetrical wheels. You can also see things like old designs for saddles.
“Technology” provides helpful diagrams of early war-making machines, production machinery and scientific inventions:
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.
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.
The resistor value is the most original and fun way to show you l am not a robot!
Would you like me to sing a song for you, Adafruit?
