• Foot pedal revival

    The lion kingdom once made a foot pedal shutter control.  10 years later, there was finally a need for it.

    Then came another idea make the foot pedal wireless.  The foot pedal camera controller lions made many years ago worked with the EOS 5D but not the RP.  The mane problem is the Yamaha pedal is open in the down state & closed in the up state.  It needed an active circuit to invert the voltage.

     The RP shutter pins no longer have enough pullup current for a self powered circuit.  There were 2 more xbee pro's. There were enough spare parts to bodge something together.

    It's unfortunate that the unplugged state is the down state for the Yamaha pedals.  The user has to remember to connect a jumper when no focus pedal is connected & disconnect the jumper when a focus pedal is connected.  Ideally, there would be a single pedal with 2 positions.  You're in a world of hurt without a 2 position pedal.

    1 impossible shot needed the foot pedal.

    An analog version of the piano pedal lions have used would burn over $60.  They're big & heavy.  A better solution is an analog sewing machine pedal.

    They seem to start in the 20's.  Below that, they might be single position.

    The other problem is the wireless system needs bigger batteries.  It lasts only 20 minutes on the current 250mAh batteries.
