Step 1:

Picture of

An old telephone.
A 1cm piece of wood larger than your cell and the thickness of 18/20 mm.
A piece of plywood the same size.
A USB extension
Two USB ports taken from an old PC.

Step 2:

Picture of
Open the phone and remove everything you find inside.

Step 3:

Picture of
Draw a rectangle with a pen the size of the piece of wood. In my case for a Galaxy S is 80x135. If you need to delete all the holes in the cabinet you can enlarge the size of the piece of wood.

Step 4:

Picture of
With the cutter or jigsaw  removed the piece of plastic which will be glued a piece of wood.

Step 5:

Picture of
Now precisely shaped hole that you made using a file and the piece of wood as a measure.

Step 6:

Picture of
Place your phone in the center of the piece of wood and draw all around the profile sure to draw a little wider.

Step 7:

Picture of
With the jigsaw cut out the inside, be precise in the cut.

Step 8:

Picture of
Smoothed with sandpaper good for the inside that were cut. At this point you have to practice a slot to make room for the USB connector to charge the phone. Put the phone on the piece of wood and draw the quarry, cut it and sand it always with the jigsaw.

Step 9:

Picture of
Take the piece of plywood and glue on the bottom of the piece of wood.

Step 10:

Picture of
While everything dries prepare the USB ports. I took a laptop broke a piece of card with two ports, you must remove all the components soldered because the ports are connected to each other but there is no hardware that could handle and then create a short circuit.

Step 11:

Picture of
Once cleaned and cut in the rear of the phone base to track and get an opening.

I like seeing instructables like this merging new with retro as I am am old duffer and don't like the cell phone culture of miniaturization and non-ergo friendly design. I may get a cell phone and do this and the retro handset. I dislike the lousy audio of cell phones and the cramps I get trying to cradle the stupid thing to my ear and the ear buds are uncomfortable. Thanks for doing this. I have one different design I would do and that is to rework the charging plug other than USB. Other than that this is terrific.
nice idea ! virtually free (for me anyway) and its so professional looking. kept the box from my galaxy s1 and im just gunna use the foam recess my phone came with !

Really awesome build! I gotta try this. I like the idea that my phone can be charging and I'll have another handset to answer calls.

An excellent idea. Using an old telephone as a caddy for a cel phone. Great job!

I have been wanting to do the same project with a Western 2500 phone as the shell, I have a handset from a 2500 that I can already plug into my cell. now I just need the casing from one, and a battery kit(so I can carry it around cord free and still charging). :)
