I've just bought a 2.4G Nestbox camera.
On the bench, all seems to work OK.
The receiver is mains powered, so no problems next to my computer.
The transmitter needs 8 volts, but,
I cannot run a permanent mains lead to the proposed nestbox site.
(about 10 metres, L.O.S).
And, I do not want a transmitter continuously "sending".
Therefore, I was thinking of the following:
1. 7 AA NiMH 2000mAh in a sealed and sheltered box,
rather than a weedy PP3 (~170mAh).
2. A PICAXE circuit to switch the power on/off as required.
3. A 433MHz transmitter to switch on the PiCAXE output,
to a 5v latching relay.
When off, the PICAXE "sleeps".
I'm not too worried about the battery drain, as I can change them every few days.
Any comments or better suggestions?
