I built this to watch garden birds when nesting.
I have 2 triple nest boxes, fitted with cheap cctv cameras.
Cameras are 9vdc, with 6 I/R leds and audio, about £8.50 each.
The reciever is mounted close to the boxes, inside the garage, and the transmitter is in the bungalow.
The transmitter is controlled by Infra-red handset.(TVR010)
Cameras scroll through one at a time.
Speed of scroll is adjusted by the '-' & '+' buttons.
A piezo gives audio indication that I/R command has been received.
1-6 select camera to constantly display, power button resumes scrolling.
0 enters routine to disable/enable cameras, enter 1-6 then power button.
camera will be skipped when scrolling.
provision is made to attach a 20X4 oled, but I only used it for initial setup.
Audio is amplified by an LM386, refer to datasheet for further info.
U1,2,3 - CD4066
U4 - picaxe 20X2
U5 - LM386
IC1 - 78l05
C1 - 100uF 16v
C2,3,11 - 104
C4 - 10uF 16v
C5 - 47uF 25v
C13 - 100uF 25v
Q1,2,3,4,5,6 - BC547
R1,2,3,4,5,6,8 - 10K0
R7 - 22K0
R9,10,11,12,13,14 - 1K0
