klar? Mein Rat wäre daher: Schalte Highside (also die 3V3 mittels PMOS), das kann man mit einem IRLML6402 machen. Der geht auch mit 3V, und ist auch spezifiziert dafür.

Kauf den > billigeren Transistor. Nimm lieber MOSFET. z.B. 2N7000 oder so. Ich nehm gern IRLML6402 (PMOS) oder IRLML2402 (NMOS). Wie geht das aufs Breadboard? Naja, ein Stückerle Lochraster mit Beinchen dran halt. Hat den Vorteil, dass man die Beinchen wechseln kann. Sonst ist bei mir eh alles

einer Lithium-Zelle die Schaltung versorgen zu können. Dafür dürfte es schon reichen als Q3 einen IRLML-6402 einsetzen zu können. Die Widerstände sind ja in den Werten problemlos anpassbar.

Hallo zusammen, ich habe den Transistortester von Markus F. (Version 2.1) erfolgreich nachgebaut. Da ich mich etwas mit der AVR-Programmierung auskenne, habe ich den Quellcode analysiert und verändert. Die wichtigsten Änderungen sind: Entfernung aller Texte und Parameterdaten aus dem EEprom in den Programmspeicher.(Vorteil: Programmierung in einem Rutsch, es kann nicht mehr dazu kommen, daß EEprom und Flash-Speicher nicht zueinander passen) Für die Kapazitätsmessung wird die Zeitmessung mit dem Timer1 des AVR zusammen mit dem Komparator durchgeführt. Speziell für kleine Kapazitäten
