Hi--
I'm a super beginner in electronics, although know electrical stuff.
I have a fish pond and a heron keeps eating my fish.
I bought a very cheap motion alarm like
http://www.amazon.com/gp/product/B0..._m=ATVPDKIKX0DER&pf_rd_r=0PHYQ0YZ9T5P5MMC2FR5
which seems to work fine, but will drive all my neighbors away as well as the heron.
I think 2-20 seconds of the alarm will be fine to scare the heron.
This alarm has 4 AA batteries so is only 6volts.
Is there an easy (555 or ???) timer circuit that will work on this?
Any help appreciated.
Thanks,
Phil
