    Frequency Division

    You can also use a multi stage Ripple counter;  every stage will divide the input frequency by 2 and so a 16 stage counter will output a frequency of 61.03515 Some extra logic will be necessary to correct the output and to further divide to 10 Hz. CMOS Ripple counter datasheets:CD4020BC.pdf

    Help! I have a Really Weird Part

    It can be a shockley, but its behavior when voltage drops to +10 V is a bit weird;

    Clocks - Integrated?

    A 4060 is even better than the 4020 because you can use its internal ports to create the 32768 kHz, as in the circuit and datasheet below: CD4020BC.pdf

    Clocks - Integrated?

    A very simple and accurate way is through a 32768 kHz crystal oscillator followed by a clock divider. dt26_dt38.pdf

    Whats a switching diode?

    Switching diodes are fast diodes that show low losses when used at medium/high frequencies.

    Convert 0-30V 3A PSU to 5A or more

    Roomi, as audioguru and indulis already said, there is no problem to exchange a large capacitor to some smaller types in parallel. ESR and parasitic inductance will be lower with a parallel capacitor assembly, but this will not affect its performance (in fact, if this was a switching power...
