    First photo is an attiny IC kindly made and programmed for me by martin 555 to send a message in Morse code from the Morse
    signal lamp
    . Commenced building various vero boards circuits, from left after martin’s IC the first is the two unequal cycle timers for the d/f and Morse light. Second is the variable voltage controller for water pump and direction finder. Third is switching controller on throttle to bring on d/f, water pump and smoke generator. Fourth is a voltage regulator three of them two 6volts for lights and smoke generator and one 5volts for Morse lamp. Fifth is unequal cycle timer to simulate flickering boiler fire working with smoke generator, (Tried flickering leds but not happy with them). Also have a quad switch for lights and single switch for horn from action electronics. Unable to find that type of circuit to build so had to buy them.
