La tête laser Elektor transforme l'horloge de sable Elektor dans une horloge qui écrit l'heure sur un film qui brille dans le noir au lieu de sable. En plus d’afficher l’heure, il peut également être utilisé pour créer des dessins éphémères. Le pointeur laser de 5 mW, avec une longueur d'onde de 405 nm, produit des dessins vert vif sur le film qui brille dans le noir. Pour de meilleurs résultats, utilisez le kit dans une pièce faiblement éclairée. Attention : ne regardez jamais directement dans le faisceau laser ! Le kit comprend tous les composants nécessaires, mais la soudure de trois fils est nécessaire. Remarque : Ce kit est également compatible avec l'horloge de sable d'origine basée sur Arduino de 2017. Pour plus de détails, voir Elektor 1-2/2017 et Elektor 1-2/2018.
