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:
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
