The handset

As one might remember from the diagram on the first page, we need to fit a lot of components inside the handset; The USB hub, USB soundcard, USB WiFi, OLED screen, install a larger speaker, route a cable for the original microphone, hook up the leds and re-route the power switch to power up the PC.

I'm going to utilize original wiring as much as possible. Trying to keep the phone appear stock.

After unscrewing couple of screws and breaking few plastic fastners, the handset was open. Inside I found a plastic middle layer that separated the keypad and the circuit board from each others. That green bit at the top is actually the back lighting for the LCD screen. It has optical fibers glued side by side to make a "mat". This then routes the light out from the handset through the LCD screen.

Here are some of the items that will end up inside the handset.

Hack the pla... hardware!

The soundcard is a "noname" OEM unit from China. Only around 5 euros and thus perfect for this build.

On the 2. part of the image, one can see the circuit board of the soundcard. Nothing too exciting there.

On part 3. one can see the result of the strip. No USB connector, no leds and no audio connectors. Microphone is the original one from the headset but the speaker is taken from the docking station part of the phone where it used to work as a hands-free speaker. Now it is powerful enough to listen music and hear audio tracks on movies as well. It can also be used for Skype calls, Ventrilo chatting etc.

Idea is the same with the Mvix's Wireless-N WiFi adapter. Strip the casing and take the connector off so that the unit is as small as possible.
