belated update on monday
monday was another ordinary day in university of southampton. there was a bit of monday blues...everyone seems to be tired and sleepy for some unknown reasons.
As the IC of the day, I have to say sorry because this post is really really late...anyway, monday was about advanced soldering practicals and more theories on AM and FM radio.
Soldering might be fun if this is the first time to try, yet it can become very challenging (sometimes frustrating as well) when the electric components become smaller and integrated circuits are involved. Probably the most exciting part today is the SMT (surface mount technology) capacitors. The SMT we are dealing with are 805which has surface area less than 50 mm^2. However, those SMT in the handphones, PDAs and other electronic devices are probably one quarter of this size...thank goodness machinery facturing is employed in soldering...though hand soldering is required when constructing prototype.
Amazingly the theory behind AM and FM radio coincides with our recent physics lecture on ocillation...anyway, waves transmitting radio signals are in simple harmonic oscillation. These theories, though far beyond A-level physics, are still pertinent to what we know and what we can apply.
Tuesday will be c programming...much more to look forward to

Day 9 pics
Don't be deceived if Lyn Lyn tells you she can't cook. Her fried rice is superb.
Mr Denis Nicole conducting the theory session before the hands-on.
Students working in groups of 5.
The almost final product. Testing will be done on Wed evening.
Sunday--A visit to Southampton Central~~
Yesterday was really an relaxing day for all of us as we met at 9:45 and could sleep late!Actually I woke up at 7am as I promised my friends that I would get online chatting with them. After a freshing breakfast, everybody slowly strolled down the stairs.(Sadly, our group is always on time and has to wait for others~~)
We took a bus and arrived at the Southampton Civic Centre at 11am. The weather was really nice.Actually after arriving it was free and easy and we split into several groups.
For our group, we went to West Quay and Maritime Museum.We were just amazed that even guys could shop as well(haha)! West Quay is really a place worth for shopping, can you image that one branded T-shirt only costs you 5 pounds? Or can be believe that one pair of Adidas Sports shoes only cost 15 pounds? By the way, it was Liang Xu who found this shop that had 75% price off haha. Each of us bought a lot of stuff in West Quay. Nevertheless,we also had a big hole in our pocket!!
It is really worth to visit the Maritime Museum. We had a glimp of how Titanic was built and constructed. We are just amzed by the ship models inside the museum. Sadly, we were not allowed to take pictures inside.
After that, we went to the seaside. However, the sea water was quite dirty and we only spent a few minutes there.
Overall, yesterday was a nice day for all of us and I am sure that everybody did spend money on buying gifts haha~~~
