Null Phone Adapters for Sale

IMG_4031I am currently selling adapters that I have built that allow you to connect two computers together via modem’s without the need for any phone service. These are very simple to use:

  1. Plug phone cables into the adapter from the 2 computer’s modems
  2. Plug 9volt battery into adapter

From here you would just use the terminal programs (or BBS programs) you have on the 2 computers to get them to talk to each other.

IMG_4029If you want a more permanent solution than the 9 volt battery you can replace it with a DC adapter, red is positive (+), black is negative. I have tested it with voltages from 4.5 volts up to 12 volts though I recommend sticking with 9 volt.

If you want to build one yourself you can look at this webpage for the details on how it works (http://www.jagshouse.com/modem.html). Parts wise you will end up spending about the same as I am selling them for.
