Prototype Completed. Poster Completed.
After spending 2 full days in the lab until late evening, the prototype and poster is finally completed. The prototype is fully working with the circuit and the poster has been designed and will be printed by this weekened to be presented.
On the 15th of March, the group done the soldering of the internal circuitry, fixing the IC legs and the IC Dye. Soldering was mainly done by Yang while the IC Dye was done by Tong Jiun. The cutting of the IC Legs as well as the IC connectors from the IC leg to the IC Dye was done by me.
On the 16th of March, the group started soldering the extended wires from the Circuit to the Real IC attachted to the bottom of the Dummy IC. Extended wires were needed as the current length of the wire was too short to display the Circuit properly. While I was helping Jin Yang with the soldering, Tong Jiun was working on the 2nd layer of the IC Dye. After that, we tested the IC Circuit and it worked. Apart from that, it is also discovered that the circuit would also work when it is conducted by a human body. This is because circuit only requires very little current to complete the circuit. However, this method does not work with everyone who tested by holding both terminals with separate hands. This is due to the difference of resistance in different human body and also the moisture of the contact point of the terminal and the human body. It is noticed that the more moisture the contact point is, the higher frequency of beeps is generated. Thus an idea was generated that this could actually be used as a gimmick to attract interest from regular people so that they would be more interested into knowing on how does an IC actually functions. The plan was to create a simple 'love-0-meter' that is able give responses when two people are holding each terminals while holding each other's hands. If the speaker is able to give a periodic beep then they are meant to be together. Else, they are not a good match. After the test, questions of how does this 'love-0-meter' work is highly expected. Thus, we are then able to move on to the details on how the IC actually works.

This is the poster that has been designed by the groupmates.
