Time-Lapse Package
Revision E
Circuitry Panel
All of the electronics and wiring are attached to an aluminum plate, which are held in place with two screws for easy access or
replacement. The cables that connect the components have unique
connectors, so you won’t have to worry about identifying cables.
Time-Lapse Controller
The’ brains’ of the time-lapse system is the venerable DigiSnap 2100.
This device, designed and produced at Harbortronics, is a digital camera
controller, developed to work with a variety of digital camera models.
The DigiSnap can be configured to take pictures at any interval desired,
or to operate on a daily clock.
The DigiSnap series of controllers have been in continuous production
since 1999, and many thousands of units are in use around the world.
The DigiSnap 2100 is attached to the front of the panel using a 'velcro'
like material. You can remove the DigiSnap and power it via a AAA cell
battery, for configuration at your office, for example. The settings will
be retained with or without power.
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.
For instance, if you would prefer installation using an AC powered source, you may replace the solar panel connection with that of
the AC charger included with the battery pack. We can provide a long custom DC power cable for this scenario, so that you can place
the AC charger near an AC outlet.
The Solar Charger circuit is attached to the front of the aluminum plate,
and does not contain any serviceable parts.
Battery Converter
While the battery pack provides from 10 – 12.6 volts, the DigiSnap
controllers operate from 5 volts, and the Pentax K200D requires 6.5V.
Harbortronics designed and produces a device to efficiently convert the
higher battery voltage to those required by the DigiSnap and the digital
camera. If a different model camera is going to be installed, we can
adjust the voltage accordingly.
The Battery Converter circuit is attached to the back of the aluminum
plate. There is a fuse in the circuit which protects the circuits in case
power is applied backwards. The connectors are clearly keyed, but that
doesn't seem to stop some installers! A spare fuse is taped next to the
circuit.
