Hi hope this is the right place to ask a question.
Background
I have a blind friend who has a boat on a swing mooring. He uses a remote doorbell to get the direction when in his rowboat but the problem is the chime only goes for 8s and he is having trouble rowing and pressing the button at the same time. Has lost remotes etc.
Requirement
I want to modify a wireless door chime circuit to ring for say 3-5 minutes. It could chime every 30s or constantly doesn't really matter. Although battery may run down quicker if it chimes constantly.
Hardware
Hpm d641 series long range wireless door chime
(Photos to follow)
Question
Any help in how to modify the circuit board would be greatly appreciated.
I don't know heaps about electronics but capable of soldering in resistors or buying a breadboard off eBay.com.au and what else I need. Have read about a 555 timer but don't really know where to start with that or what to buy..
Thanks in advance!
