Nb./Ref.Verre de miroir en polystyrène : 500 x 1000 x 1mm / No art. 3374630
Price19 CHF (Avec un plaque on peut faire au moins 6 réflecteurs)
Amélioration du réflecteur.

Le réflecteur peut être amélioré ce qui augmente la puissance du mobile et facilite son fonctionnement.

J'ai remplacé le papier aluminium par une plaque miroir souple.
Celle-ci peut s'acheter en plaque de 100/50cm dans les grands coop-brico.
La plaque est assez rigide et pour la faire tenir en forme de parabole
il vaut mieux riveter les deux bouts ou faire des trous et les faire tenir avec des écrous et vis.
