Pre-Easter Demo Session

Today, we have a group meeting to test the new electrode I bought it yesterday. The new electrodes are fit perectly to the device (as shown in Figure  and these can be reuse many times as these don't need the gel to stick to the human. The signal generated directly AD9850 DDS and the one pass through the electrodes to our body are nearly identical.

Figure 1: An Electrode in use.

In addition, we change the signal detection code to make it even more accurate and test it. The below videos shows the test of the device with the electrode.

The test result is amazing. Both user can control the tank directly or through touching each other hand. This is a very promising result.

By the end of today I think I will have 2 tasks to do

1. To symplify the already existing code of the Tank application. At the moment, the Tank application is written by 1 python file which includes the code to detect the signal from Pico Oscilloscope. I believe It is best to seperate the detection code as a seperate module and other games or applications have just import it and use it. I will make it easier for the developers to maintain the signal detection and the applications. The jobs can be independent. The application, game developers dont need to know about the detection code, they have just rather use it. On the other hand, the device developers can make changes and update without interfere with the application development.
2. To implement the painting application to demonstrate the functionality of the collabrative touch device. Initially, I think this will be easily implemented by using existing free painting source code. From that, I can just added neccesary functions to adapt to new input in this case requencies.

Thats quite alot of work for today (nearly 7hours work) before Easter. I can see that everyone in the group are excited with what we got so far and we are also work hard. Specially Paul, he is the key idea and role in this project.

Anyway, Happy Easter!!!
