How to build a handset for your cell phone

Handset for cell phone

Before you start, you need to take a look at your cell phone and identify how you would connect a headset to it. I have found by looking at several cell phones that most of the time this is accomplished by plugging in a 2.5mm Stereo Phone Jack (sometimes called 3/32″). You can double check your phone by comparing a standard headphone jack (like off your ipod) and verify that it is quite a bit smaller. A standard headphone jack is 3.5mm (1.8″) I mention this step first, because it is very important that you get the correct phone plug before you heat up your iron.

After you have identified what type of phone plug you have on your cell phone you will need to assemble the following parts:

  • Right Angle 2.5mm Phone Plug : Radio Shack Link : (or whatever size you need)
  • Telephone Handset that you intend to use (see below)
  • Assorted Hardware Hacking tools such as Wire Snips & Strippers, Soldering iron, Helping Hands, etc..

The rest of the instructions

Of course you can just buy one for $30.
