The Media Computing Group : Back to Tools The original FabScan was developed by Francis Engelmann in his Bachelor's thesis (cost of materials: 150 Euros).
FabScan 100 further reduced material cost so that you could build one for just 100 Euros. FabScan Cube then featured an improved housing, as a result of a student group working on interactive assembly. FabScan Pi is the latest version. It includes a Raspberry Pi embedded computer for standalone operation and wireless scanning: Instead of controlling it from your laptop via USB, you can scan wirelessly from any web browser.
Paper Speakers (various materials) Fabriquer un zootrope. Un oeil neuf sur la lumière : fabriquez votre spectromètre. Traduit par Camille Ducoin La lumière blanche... n'est pas blanche : elle est constituée de beaucoup de couleurs différentes.
La composition de la lumière (son spectre) s'étudie grâce à un appareil nommé spectromètre. Nous verrons dans cet article comment en construire un, rien qu'avec une boîte de céréales et un disque compact. Cet instrument fait-maison nous permettra d'admirer le monde merveilleux des couleurs cachées dans les objets environnants, comme les ampoules, les tubes fluorescents, les écrans d'ordinateurs et les flammes de bougies. Explorons! Comment décomposer la lumière Il y a plusieurs façons faire apparaître les couleurs composant la lumière blanche. Une autre façon est d'utiliser une grille de diffraction formée d'un grand nombre de sillons minuscules tracés parallèlement les uns aux autres sur une surface, comme il est montré ci-dessous.

Paper Chromatography. Magnetic Boats made by Jitter Davy. Build: Heron’s fountain. This week I am actually going to be making something that does not require electricity.
Although, you may be able to fool people into thinking it does. We are going to be making Heron’s fountain out of common household materials. This is a really easy build and would be a perfect project for to build with your kids. Maybe you could even sneak in a lesson on fluid dynamics or perpetual motion? Heron (Hero) of Alexandria was a mathematician and an inventor. Total cost of build = $2 (you can scavenge the 3 water bottles) What You need: Supplies (3) 16.9 FL OZ Water bottles (I used Dasani) (1) 9″ length of tubing (1) 11″ length of tubing (1) 15″ length of tubing Small amount of clay (Play-Doh) Note: The tubing is for aquariums and is 3/16″ thin wall rigid tubing. What you need: Tools and equipment Scissors Drill (hand or electric powered) 5/32″ drill bit (slightly smaller than the tubing diameter) Step 1: Make the fountains’ reservoir Cut (1) of the bottles in half as pictured.
