Yes I use a raspberry pi
The 4 comes with 2 camera
ports.
The new raspberry pi camera recently took the best quality photograph from a land based camera. It’s 6mm. Sony tech.
It’s overkill for a
boat Several good cameras with wide angle lens $35.00
I’ve added to the raspberry board
Servo shield 32 channel controls servo or stepper
motor
AV shield Mini card memory chip to
record data or film
Battery Shield 2500mA Lipo
charger 3.5V
The raspberry consumes 1250mA an hour @ 3.5V it controls 5V servos and relays through a step.
The servo shield unlock a
hatch and another push pin opens the
hatch for 45 minutes then relocks. The command is start air.
The shield also runs two 5V servos for an out door camera. I 3D printed a housing to hold a camera and two tiny servos. The camera worked the servos froze in the
winter and were fine in spring. The raspberry watches battery state humidity and turns on two golden rods to reduce the chance of mildew.
I also made with my grandson a dissolved oxygen
sensor which worked great till it drew 2Amps.
So we are winging it.
I designed and printed a case for the whole mess with
cooling fans and stuffed it in a wall. It has
wifi blue tooth and I could add a cell number for $30.00 a year and another shield to solder up.
The front
cabin roof is 6’. The door isn’t I always hit it. Might be the
rum. So I sleep in the aft has 6’ door. My wife found a 2D Duck about 4” I drilled a hole it it and have the raspberry camera hidden in it. If you enter the boat my
phone or my wife’s will get video. It will also pretty much kill the battery.
I need to add a direct step down
power source to fix that. There is no room for a bigger battery and I don’t want to add the heat.
2 minutes of camera recording and it’s dead. It’s actually caught me hitting my
head. The exterior camera is good to -10c then anyone’s guess. Would
work perfect in the correct climate. I have designs for clamp on and screw on. Mine was just a weighted base. It’s easy to print 7
parts and two micro servos the 9mm and the camera can swivel 355 Aim -10 to 110 degrees. I printed in white
Asa which has great UV chemical fuels resistance as strong as cast
aluminum. It’s on my top five plastics list but perfect for
marine.
