    I created this schematic from a request about a printer heads tester.
    The circuit can be helpful to drive 24 outputs, using three 4017, a 555 multivibrator, and three relays.
    RS1 turns the clock signal to IC2; RS2 turns the clock signal to IC3.
    Once RS3 is activated, all pin 15 take the high level, so the circuit backs to the start condition.
    On this project the relays from R0 to R24 are required because they must drive 24Volts heads.

    We have had problems with the files associated with projects becoming lost over time when the off-site hosting has a problem or simply stops handling the files.

    Could you transfer the schematics (as PNG's) and the descriptive material to the AAC server? That way they will always be available to interested parties.

    Please read the rules of the Completed Projects forum.

    This project has sat in limbo basically because it didn't meet the above requirements. If you want to resubmit this entry please rework the entry to meet the requirements, then drop one of the moderators a PM pointing to it. If it is acceptable a moderator can move it back to the Completed Projects forum and clean up notices and suggestions (making them invisible).
