Hello there feiges here Ive moved into my new apartment and I now have 5 phones throughout My roomates pick up on my conversations and modem. I need a simple little 'in use' light or LED device. help?! Ive noticed that when I place a 1.5 volt LED (it gets a little warm) in series with the phone line, when a phone is picked up the circuit is completed and the LED lights. Is this bad? How will the LED affect the phones throughout the house, or the modem even? Should I put 5 of them in series or parallel? Should I scrap this plan and build some other device? What to do? please mail me responces to the following addresses (mail to both if you can becauese one address may be deleted this week, I am not sure) feiges@jomby.cs.wisc.edu and feiges@cae.wisc.edu thanks tons tpk
