Hi all, I’m just wondering if anybody knew how feasible it would be to hack a telephone landline so that the spark knew when there was an incoming call and could flash lights around the house to indicate that it was ringing for the hard of hearing ( have seen hacks for lightwave rf wifi box that would allow this via php ) … I’ve done some basic research and can see that the line is 50 v, and 100 when there is an incoming call… So I guess the core could measure the difference somehow to identify a call? - would also be cool if it could use the line as a powersource too. - obviously wouldn’t want to impact broadband signal or line quality though. - what do you think? Feasible?
