State-of-the-art X-ray scans have revealed the internal mechanisms of a corroded, barnacle-covered pocket watch recovered from a seventeenth-century wreck. The watch looks little more than a lump of rock from the outside, but the scans show that the mechanism inside is beautifully preserved, from delicate cogwheels and Egyptian-style pillars to the maker’s inscription.
Researchers from the National Museums Scotland in Edinburgh used the images to construct a three-dimensional virtual reconstruction of the watch’s lost workings (see video flythrough). They hope to use the technique to probe the internal structure of other archaeological artefacts, especially those salvaged from underwater sites. The watch and three-dimensional reconstruction are now on display in the Treasured exhibition of the National Museum of Scotland until 2011.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
