Bare conductive has made a board for playing MP3-files on an external speaker. The sounds are stored on a micro SD card and you trigger the sounds by touching metal points corresponding to the files. However, the metal points can be extended by crocodile clips, cable, foil or anything metallic. This opens up for using your imagination to create a shape or space that plays music or sound effects when interacted with.
This is a circuit board that will work as a light source with a number of prepared behaviours and inputs. Perfect for those not comfortable with programming or soldering. Powered through a USB micro connection, meaning it can be powered with computer, powerbank or charger plug. More details here: https://www.bareconductive.com/make/light-up-board-modes/
For a project with Komatsu Japan we bought a remote controlled dumpster truck and dito excavator. We then combined them with cameras and receiving goggles used in drone racing to give the opportunity to experience driving vehicles mimicking the circumstances for professional remote controlled equipment used in some mining industries today.
Lumecubes are small but powerful LED lights used for lighting up smaller things like products or faces. They can be controlled either by buttons on the cubes themselves or via bluetooth in an app! Typically for photography, but also for any light up needs in general. We now have two kits with a cube in each with a charger, cable, phone mount and some filters n things.
