    Hi Guenther,

    This makes Lectron so exiting ! Building circuits in a easy and fast way and creating new blocks with these circuits.

    Also thank you for great looking modules and designs !

    And also many thanks to Michael for giving us the forum platform to substitute ideas.

    Indeed, by changing the light bulb to other types, we can alter the cutoff current.

    For a permanent design, we can use a BC517 (Darlington transistor) which is able to deliver 0,4 A Collector current (the Silicon 2N3704 transistors used in the Lectron sets have 0,5 A).

    The light bulb is also interesting compared to a normal resistor since it also acts as a VDR (Voltage Depending Resistor) as the filament heats up and thus increasing the resistance.

    Many greetings
