From Devices to systems

What to Be Unboxed?

I was excited when I heard about the assignment since I always want to take apart machines. And this assignment gave me the best reason to do it without the worries of putting it back and make sure it works again. Two things I want to assemble the most, the first is analogue cameras and the second is radio. I quickly ordered a camera online. But when I received it, I realised that it is too simple to be disassembled. There are no electronic involves in the whole camera, and the construction of the camera is very plain as well. On Tuesday market, I went to the market and luckily found an old radio produced in 1972 which became my unboxed machine.

About the Radio

The radio I brought from the market is an old radio produced by the brand called Galaxy, the model is mesa 6000 and produced in 1972. The radio still worked perfectly when I test it, all the buttons, the warner, the speaker worked in good statues. Yet when I tried to open it up, I find out the all screws are rusty and few were even stuck so I brought it to the metal station and open it up with a screw extractor.
