    Updates!
    13 March 20112012
    Thanks to the guidance from Mr Richard Chee, we (Anton, Fabian and Zhiwei) have gotten the level shifter to work and managed to get the Arduino and GSM boards to communicate with each other!
    Click here to find out more on the problems we initially faced.

    Description: A fast-forwarded video of Fabian disassembling a Dopod C800 (rebranded HTC Hera 100).
    Description: The result of the disassembly. The individual parts are laid out on the mat.
    [Xiaodong]
    I am too, like to disassemble things. I also like creating things, from rockets to home-made tasers to small programs and games. I like to bring my knowledge of science into other subjects, such as my own ignition system improvised from a circuit board and transformers:
    {DSCF2166.JPG}
    This is quite simple, the metal thing at the middle is the cathode, the anode is at the bottom. Actually it doesn't matter which is which, as long as there is a potential difference in the current, the current will flow through the transformer, which is the golden coloured object. This steps up the voltage greatly, and causes a spark to jump from one of the carbon electrodes to the other. The carbon electrodes are the two black sticks which are actually 8B pencil lead (higher purity). The yellowish object at the top is some thermate(aluminium+iron (III) oxide+sulphur+propan-2-ol+ethanol) based fuel, which goes off quite easily. Everything is improvised, the sulphur I found at home, the volatile liquids from spray cans. Just what I love to do with circuitry!
    Next is what I also like to do: disassembling. Unlike what anton and fabian did above, disassembling a laptop and a phone, I am disassembling a desktop that I just put together from some old hardware.

    This is the insides of my desktop, and if you recognise the hardware, they are extremely old. But they still work! The specifications of this desktop a few years back was very high, and at that time, it was counted as a high performance PC.
    {DSCF2174.JPG}
    RAM. 256MB DDR RAM. Now we use 4GB to 8GB RAM, and they are about a inch or two shorter.

    {DSCF2172.JPG}
    The CPU. It is an Intel Pentium. Pretty old chip, even the thermal paste can't be wiped off anymore...
    {DSCF2173.JPG}
    The network card. Not very new either. Does not support WIFI and Bluetooth, just LAN.
    {DSCF2175.JPG}
    Hard disks from my PC.
    {DSCF2176.JPG}
    82.3GB for that huge disk! A newer HDD:
    {DSCF2167.JPG}
    320GB for more than half its weight. Also, this can be used as a notebook HDD and also as a USB HDD, which is what I am using, with a HDD to USB port (the black thing at the bottom).
    This is everything from my desktop, and I plan to build a better and more modern one in the holidays. Until then, I will be doing more of the LED project.
