Christoph Thetard has created R2B2 – a small food processor, coffee grinder and stick mixer all driven by a human powered flywheel. Great to see this innovation in a market saturated with electrical appliances. By pressing a foot lever the user can generate a maximum of 10000rpm at the blade tip – more than adequate for your blending & grinding needs. Battery and power From OLPC Removing the battery from a B4 model OLPC laptop. OLPC has put a lot of effort into building a device with very low power consumption as it will be used in areas with poor or non-existent power infrastructure, with electricity often very expensive for the user. Early concept devices were shown with a hand crank on the side to demonstrate that they would work in areas where the only electricity available comes from devices like the Freecharge portable charger. Replacement Batteries and Chargers Replacement XO batteries and chargers (and other parts) are available for sale from this independent Michigan (US) store: XO-1 Power Input Specifications Read more details in Hardware specification. Also see Battery replacements for why opening up your XO's batteries is a bad idea. Electrical Specs XOs need a DC input ranging from 11 volts to 18 volts to charge the battery inside.

faire un moule pour buse en béton - [La cigale laborieuse] Les ingrédients : tôle gaufrée d’une piscine HS 50 vis et écrous de 8mm de diamètre et 60 mm de longueur contre plaqué de 10 mm tube plastique électrique de 10 mm cisaille à métal huile alimentaire Un voisin ayant abimé son liner, j’ai pu récupérer la tôle d’une piscine de 1m de hauteur et de 4 m de diamètre. Les entretoises sont toutes coupées à une longueur de 5 cm dans une barre de tube plastique et vont permettre deux choses : écarter uniformément la paroi intérieure de la paroi extérieure, protéger les vis du béton. Les vis sont fixées selon trois cercles : à cinq centimètres du haut, à cinq centimètres du bas, au milieu. Malgré toutes ces fixations, il est nécessaire de renforcer le cylindre intérieur à l’aide de trois disques en contre-plaqué. En effet, lors de la réalisation de ma première buse, le béton a réussi à repousser la tôle intérieure, et lors du démoulage, il a fallu retirer les bosses de béton avant qu’il ne soit trop dur. 30 cm du bas, 75 cm du bas, 100 cm du bas.
