The third day of our workshop have started with the recap from previous day brainstorm. We were very happy to see that participants were getting more and more excited about our project – not only about the device itself but also about the collecting data, setting up different situations to see how data varies and most importantly about practical applications of our project.
Some of the participants’ input for the purpose of looking at the action and variation potential from plants were questioning whether data from transgenic plants varies from those which are left as they were? How can we make intelligent greenhouses? Based on whatever plants will “tell” us – can we produce harmless pesticides? How can we use them to study climate change?
From proposed solutions about how to filter the noise, one suggestion was to use Kalman Filter on the software level, or to use dual power supply for the arduino (so that we can have + and – values).
Some of the participants were heavily experimenting with electronics and various components in attempt to make that dual supply since yesterday. One of the participants – Judith Cano – studies Biology and so she could explain very properly the scientific procedure of collecting data – that is to make notes about time, environmental conditions, reaction before stimuli, during and after.
Prof. Macario Baquero, although proposed a new solution on Tuesday, after what it seems a good thinking session over the night decided that our previous schematic was actually better. The problem however was within one of the chips. He got with the dismantling the chip to find out how he can change it from inside.
Carlos González De Opazo made a circuit with reversed voltage, so that we could experiment more trying to find out whether it will help with the signal or not.
Another group left their plant hidden overnight underneath a thick, black piece of rubber. They wanted to see how data will be affected by depriving the plant of the light and whether afterwards when exposed to the Infrored light it will have any effect. They also experimented with all sorts of other stimuli, while collecting data, taking notes regarding the time, position and environmental conditions – as per scientific way of doing research. That was very valuable for us – as taking as many readings as possible will brings us all closer to being able to identify the meaning of data! We will put results and graphs from that in our “Research” section.
