- 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)
