Day 1: This day was a plan day for me. I scrolled through youtube and constructables to find something of use, but my efforts were mainly fruitless. However, an upside to this was that I acquired some newfound information and tips on something similar based on this project on constructables. (2/17/23)

Day 2: This was a half planning and a half work day. I did the same as what I did on day 1, then set to build a prototype with the knowledge and materials I had. I was also thinking of scrapping the prototype idea and make the current build my main project overall. (2/21/23)

Day 3: I started working on my project, hot glueing my seams and structure to form a hollow cardboard cheese wheel with a little opening at the end. This was where I would insert my toilet paper roll. I also tried a few homemade fan structures to increase the speed of my Air-blower. (2/23/22)

Day 4: I added major features to my project, such as the nozzle, motor and the necessary workings needed to power the machine. I decided to not use a rechargable battery-charger input thing as it would take too long to make by hand or to find it on taobao or any other site. I accidentally placed the wrong type of fan into my motor and glued the nozzle. (2/27/23)

Day 5: I finished up my product, made some minor changes to attribute my mishap and added a handle as well as some taping and gluing to the general design and wiring, to ensure no damage or accidents while in use. (2/29/23)

In this project we were tasked of creating something that visualised the knowledge or understanding of the concepts and shifts of energy. I had chosen a specific video for this particular section and did some brain-storming as well as experimenting to finalize my product.

Here is the photo of my Final product.

There were some things that went wrong. For one, I attached the wrong kind of fan, that was smaller and rotated in a way that it would SUCK IN air instead of blow. When i realized my mistake, it was too late to fix it. Another problem was getting the circuitry done. In a normal case this would not be very hard, but a few drops of melted solder wire snuck their way into the chamber as it burnt through the carboard and make the fan heavier. To this day they are still there and it is a hazard due to the fact it can come off at anytime and be chucked at lightspeed into someone’s eye or mouth. MY PRODUCT BARELY ENDED FUNCTIONING, AND NOT IN MY DESIRED WAY.

WHAT COULD’VE BEEN AVOIDED: 

If I hadn’t misplaced my fan, there would be a higher success working rate of my product as the fan woutd overall – be better than the current one. I had to spend a while also adding a couple of features so that I could “ensure” that it looked like an “authentic” “vacuum” device.

WHAT I LEARNED FROM THIS:

Reflecting on my project, I overall could have done much better over the span of 2 weeks. If I had planned a bit more accordingly, and not have spent too much time looking for a project like this, I could have polished up and modified said project better than my current one.

In this project we were tasked of creating something that visualised the knowledge or understanding of the concepts and shifts of energy. I had chosen a specific video for this particular section and did some brain-storming as well as experimenting to finalize my product.

THE PLAN: https://www.youtube.com/watch?v=JQRE_d8wzBQ In this video, I took screenshots and annotated them to see what I could modify to my needs, to make the desired product. Some key features included:

• The nozzle of the Air blower (in my case sucker/vacuum?)
• Optimized Design to strengthen Air flow

I took many screenshots to reference my project with the video, and to ensure I wasn’t making any flaws. Here is a sample one.

CRITERIA: Make a device, or gizmo capable of demonstrating your knowledge about energy transfer.

FIRST STEPS: To make an easy-to-make gadget or item was my first idea. Things that came to mind were:

• Working Windmill model
• Air blower made out of fish cans
• Portable stove that runs on air (canceled, too hard)

At the end of the first week, I decided to build the Air blower, using cardboard and hot glue instead of tin, soldering and fish cans to make it.

Here is the video that I used as reference to my project. >> https://www.youtube.com/watch?v=JQRE_d8wzBQ

This is the Final product of what I had made in the 2 weeks’ time.

WHAT IS THE ENERGY TRANSFER?:

How this device works is that it blows/sucks air by the push of a button. It can be set on a table or held. The button is connected to a 9V that is connected into the inserted DC motor. As you press the button,  The mechanical/electrical energy from the 9V powers the DC motor, which spins the fan attached to it to create a sort of Wind/kinetic/rotational energy combination.

CONSTRAINTS, PROS AND CONS:

Some time constraints:

• Was planning to make a prototype so I could sort things out (prototype ended up being my main project)
• Wanted to replace fan as it was too small and could barely work (would take too much time)
• The whole design overall of my project (It does not look very appealing, rather primitive or “hobo”)

Pros: Was easy to make, materials were all there

Cons: It barely worked due to me attaching the wrong kind of fan meaning it barely sucked in dust and other fine particulates. It could not be rectified as it was too late.

WHAT I DID WELL IN MY OPINION:

I think overall the simplicity and the re-configuration was what I was best at. If i made a mistake, I was quick to rectify it (optimize the sucking airflow) as I was swift in this part.

Me, Nanda and Colin learnt a lot about the revolution while making this video, and we learnt key points about the revolution.
