Lampe de poche manuelle au service des parents
Dans la droite lignée de l'ordinateur à 100 dollars, voici un objet qui a le mérite d'éviter une surconsommation de piles. Chaque soir, notre enfant se couche avec sa petite lumière, qui est généralement une lampe de poche standard. Le problème est que nous oublions régulièrement de revenir dans la chambre et d'éteindre sa lampe. Le lendemain, les batteries sont mortes, inutilement. Nous avons trouvé une solution toute adéquate qui est cette lampe de vélo, que notre fils recharge par lui-même dans un joyeux mouvement gymnastique.
