    Le kit a besoin de connaissances plus professionnel, la création d"un dispositif complet de créer une loupe et correspondant n"est pas petit. un excellent produit et affiche une bonne composante électronique des signaux sismiques claire pour l"essai sur le circuit. Une fois que vous avez fait cela, c’est étonnamment facile ! C’est un peu une chasse, parfois, de trouver les touches droite, mais vous pouvez être assuré qu’ils sont là quelque part.Certaines pièces sont terriblement faible--comme la prise USB. D’autres, comme le connecteur BNC sont presque impossibles à chauffer suffisamment pour obtenir une bonne adhérence.Mais avec peu de patience et un fer décent, il arrivera par la suite.

    C'est le premier kit DIY que j'ai réalisé. J'avais une petite expérience de soudure et d'électronique remontant à une vingtaine d'années. Je montage est très agréable grâce à une documentation suffisante. En fonctionnement, on se rend bien compte qu'il ne s'agit pas d'un "vrai" oscilloscope mais d'un sympathique petit projet diodactique. En effet l'écran est petit, l'interface par switch pas très ergonomique. L'affichage est très correct, avec une source propre on obtient de belles sinusoïdes. Attention à la tension de mesure plus limitée que sur un oscilllo de labo. En conclusion, un projet DIY très agréable à réaliser, fonctionnel même si assez limité. Un seul regret, le port usb, non utilisé, il aurait pu permettre le transfert des données vers un ordinateur .

    Les impératifs : un bon fer à souder pour les CMS, un tester pour lire les valeurs des résistances et une petite journée de tranquillité pour mener la mission a son terme. L'impératif, il faut savoir souder, la documentation est très bien imagé. J'ai commandé aussi la boîte et j'ai dû m'y reprendre à trois fois avant de comprendre l'ordre de montage des vis (pas de doc) mais au final, tout est parfait. Surtout rester ZEN pour le montage.

    J’ai commandé le kit comme une petite aide pour les mesures occasionnelles. Le kit est venu comme décrit à pointe de SMD, vous devez souder sur toutes les autres parties. Si l'on suit point par point les instructions en anglais seulement, réussir facilement. En particulier, je tiens à indiquer les deux cavaliers de complet - ils sont faciles à voir, si ce n’est pas exactement prendre le manuel. Dans l’ensemble un super rapport qualité / prix. La taille de l’écran limite la lecture exacte directement dans les graphismes bien sûr, mais il y a une manière ordonnée des formes d’ondes. Comme une aide rapide avec le métier, il est bon d’utiliser à mon avis. Une dernière remarque encore : l’axe des abscisses est réglable jusqu'à 500 s / div, gradients de température ou similaire peut sans doute mieux présentés ainsi - je n’ai pas testé mais.
