(1) Any hard plastic sheet to make charging base stand (I had used plastic from square plastic bottle, image attached)
(2) Nokia to sony erricson - old mobiles' charging adapter. (image attached)
(3) Ordinary USB cable with power surge protection (not a must thing to have power surge protection).
(4) Two sided sticking tape. (image attached)
(5) Scissors and sharp blade to cut the plastic sheet.
(6) Soldering iron.
(7) Original sony charger - the one which came with your mobile.
(8) Quick fix to stick the things together.
First of all, you have to make charging case to adapt the phone, measure the width of the phone, add 2 mm to it, draw square (black square as in figure) with this width and height on the plastic sheet from which you intend to make case. Now measure thickness of your phone, add 2 mm to it, draw two parallel lines (blue lines as in figure) on the adjoining rectangular lines on the square, secondly draw another two parallel lines (red lines as in figure) parallel to blue lines to make supporting sleeve. Fold them according to shown in figure, and stick them with quick fix to hold them in place. Allow it to dry.
Then put your phone in this case, mark the placements of golden contact ports (dock ports) on the side wall of the case with pen.
Take the charger adapter, adjust the contact pins according to distance between golden contact points of phone, cut the space on the side wall of the plastic case to fit this charger adapter so that after fixing it, the contact pins of adapter comes in contact with phone golden contact ports.
Now, cut the second end of USB cable (the end towards the power surge protector), find out which one is +ve and which one is -ve, and solder them to the pins of charger adapter after opening the covering of the adapter (non branded adapters are easy to open) so that +ve PIN COMES IN CONTACT TO THE UPPER GOLDEN CONTACT POINT OF THE PHONE, second one is ground, so solder it to the remaining contact pin. Close the cover of charger adapter, remove adjoining plastic insertions pins up to the base, fix adapter with quick fix to the already cut out space of the side wall of the plastic case and allow it to dry.
Plug this USB to your original charger and the DOCK IS READY
You can stick the case to wall with two sided tape as shown in photo, so that when phone is placed in the case, it remains tilted and hence by gravity, golden dock port comes in contact with charger adapter pins.
Hope this tutorial will help you.
