C51 4 Bits Electronic Clock - YSZ 4 Hacked

Had some spare time this weekend so went ahead and assembled this AU$2.40 4-Bits DIY Electronic Digital Clock which I bought from AliExpress a while ago.

Unboxing
--------
I bought this DIY kit from "HESAI 3C Electronic Components Store" from AliExpress for just AU$2.40. I have provided the store's link in the description below. The packaging was good and the item was delivered to me in just 15 days.
The item came with a circuit diagram and a list of components included in the packaging. Including the instruction sheet, there are 18 items in this packet. You can find a scanned copy of the circuit diagram in the description below.

Frankly speaking, by looking at the components it doest look like you really need to be an electronic genius to assemble all these components. I guess all you need is just a general purpose soldering kit and a bit of your spare time.
