Time-Lapse Package

Solar Charger While many solar panels can be connected directly to Lead Acid batteries, LiPoly
batteries must be charged carefully, monitoring the voltage and temperature.
Harbortronics has developed a custom charger to adapt the solar panel to the LiPoly
battery pack. This device is installed between the solar panel and the battery, and also
provides connections for the battery converter. Other external power sources can be
used in place of the solar panel, as long as the voltage is between 12 and 20V.
While the battery pack provide 10 – 12.5 volts, the
DigiSnap controllers operate from 5 volts, and the
Pentax K110D/K100D requires 6.5V. Harbortronics
designed and produces a device to efficiently convert
the higher battery voltage to those required by the
DigiSnap 2100 and the digital camera. If a different
model camera is going to be installed, we can adjust the
voltage accordingly.
The cables that connect the battery converter to the
other components have unique connectors, so you
won’t have to worry about misconnecting power.
Tools are provided with the Time-Lapse Package, to allow reconfiguration
of the camera position, the solar panel, the mounting brackets, and to open /
lock the door
A desiccant pack is included in the housing to minimize internal moisture,
which can cause condensation during temperature extremes. If the crystals
eventually turn pink, bake the pack in an oven at 150C / 350F for an hour or
so, until they turn blue again. Be careful!
We also include a sheet of black felt, in case you need to absorb ay other
stray internal light reflections.
