Optical Camera
Solder a wire with a female connector to the third pad from the bottom on the backside of the camera. This allows manual control of the IR filter by the Raspberry Pi. Connect the other end of the wire to GPIO pin 40 on the Pi for use with the take_nir_photos.py script.
[WittyPi 4]
Solder a 7-pin male header onto the P3 connector along the edge of the WittyPi 4 board. This header will be used to supply power to the mDot module.
Current order of installation:
Modify NIR camera, install passive heatsink, install WittyPi 4 with CR2032 battery, connect NIR camera, connect cellular modem, connect Flir Lepton, connect mDot, insert microSD card, power on and test device before installing into case.
Drill holes for cameras and external power (and antennas if too large to fit within or signal blocked) into case, place components and battery into case, install cameras, connect antennas. Power on and test device.
Apply silicone sealant to all openings into case, and install LWIR transmission window for Lepton. Check water-resistance before field installation. Connect to solar panel power.
Remove the photo resistor (light sensor) from the Dorhea IR-CUT camera.
Remove the photo resistor (light sensor) from the Dorhea IR-CUT camera. You could remove it by snipping the two leads that connect it to the board, or apply heat with a soldering iron to the two leads and use a solder sucker or solder wick to detach them.
Solder a wire so the IR filter can be manually controlled by the Pi. The wire is soldered to the third point from the bottom of the camera on the backside and connected to pin #40 on the Pi for use with the take_nir_photos.py script.
Before removing the photoresistor:
Software is already configured on the SD filesystem image. If installing from scratch follow installation instructions for the WittyPi software before installing the WittyPi hardware.
Install the heatsink, standoffs, and connect the camera ribbon cable before placing the WittyPi on the GPIO pins.
Screw down the hardware so it stays attached. Create a startup script or SystemD service to run the WittyPi network time synchronization when networking is available to get an accurate system time - WittyPi stock software disables Chrony, systemd-timesyncd, etc.,
Install the miniPCIE card into the USB adapter.
The mini PCIE card is the component on top and the USB adapter is the component on the bottom of this image:
