Problems and Thoughts:

Throughout the project, we rarely had problems. And one of the problems we had were not solved even now, the problem was this, the sensor was not accurate enough, or not functionable enough, to measure one’s heartbeat without one needing to precisely place one spot of their finger to one spot of the sensor. Many people people did not find this “magic spot” and failed to gain any reaction from the screen. This problem was beyond our knowledge so we decided to ignore it, as there was nothing we could do. The other problem was discovered early on, Clarence had doubts on whether the project would work when it arrived, because we had to deal with apparatuses that we had no previous conception of. But in the end, our doubts were misplaced, and we complete the task with surprising ease. I think this project was a good chance to get some real experience, but let’s be honest, we only watched and emulated youtube videos online, I did not have any scientific mindset during and before the 4-day making process, only when other people’s final products were shown to me, did I really start gaining any ideas of my own. For many of the projects of others, I do not even see a direct connection to the subject we were given. I guess one takeaway was that gained a rudimentary understanding of how Arduino’s and wires work, although lots of the parts I don’t even know the specific detail of.

Actual Ideas: 

Speaker: this device can produce sound energy by converting electrical energy into mechanical energy, when there is a sound, an electric current is sent, and it creates a magnetic field and interacts with the permanent magnet, making the cone vibrate and thus creating a sound.

Waste Energy Converter (failed): in this product, I will use the thermoelectric generators to convert wasted energy – from easily overheated objects such as car engines, computers, and iPads – to electric energy. For powering lamps, charging phones, or storage for later use. This failed because it’s too hard to capture small amounts of heat difference (computer overheat), it can only capture a significant amount of difference.

Defining my problem, user & constraints:

  1. What problems or needs could be addressed in my product?

Energy Capture and Storage

2. Market analysis relating to the topic of Energy Capture and Storage in which sale is possible

  • People with less/no access to electricity and have no choice but to try to catch up with contemporary devices. My project could be to provide them with the ability to charge without need to pay electricity bills
  • People who like to go camping might want to use their phone to take photos or contact their families might not have the conditions to replenish their phone, I could design an apparatus that charge their phone using solar or kinetic energy.

3. What problems could arise in the future?

  • What could be made in the time restraint of a mere five lessons?
  • With all the already original designs out there, how can I make something original?
  • How do I know about the accessibility of whatever materials I need?
  • How do I generate 30 divergent ideas?
  • What will I use to design my final idea, though I only know tinkercad

4. Examples – Precedents

Solar Panel: This type of energy capture device captures and utilises the most common source of energy, which is the sun. This device captures the light energy and NOT heat energy of the sun. This could relate somehow to my idea, as I could use solar energy as a source of charging phones if in the nature, especially for someone who is in the desert.

Windmill: A windmill is a structure that converts wind power into rotational energy (kinetic)

Watermill: A watermill is a utilizer of hydropower, though not usually used to produce electric energy, it can be modified – like a windmill – to do so.

Speakers: Speakers work by converting electrical energy into mechanical energy (motion). The mechanical energy compresses air and converts the motion into sound energy or sound pressure level (SPL).
