Final product

Explain how it works/doesn’t work using scientific terminology.

The battery holds chemical energy that is transformed into electrical energy by the circuit. This electrical energy is then transformed into light energy by the LED strip when current passes through the PN junction. In essence, this means that light is produced when electricity passes through diodes and combines with the gaps and electrons in P-type semiconductors.

Explain the areas of success you found in the process

The design was good, and we didn’t have any trouble creating the dreamcatcher and even finished ahead of time with one lesson to spare. I’m proud of the way we worked quickly and efficiently,

Explain the areas you need to improve in the product

As our feedback stated, we could’ve put feathers on the battery pack to hide it. However, we decided not to because hot gluing it on could be dangerous. We also tried to tie it, however, it would constantly swing around and not do its job of hiding the battery pack while making the dreamcatcher look cluttered. Next time we could find a better solution to hiding the battery packs

Explain the impact of this project on the environment, and the potential client/consumer/audience.

Our lamp is relatively eco-friendly, we reused all of our supplies like the string, beads, and metal ring. However, our project uses single-use batteries instead of reusable ones. Additionally, as we used LEDS, the PN junction uses the conversion of electrical energy into primarily light energy, which saves a significant amount of energy compared to conventional light bulbs, which generate a lot of thermal waste energy.

Create and Improve

21/2/23

we started making the feathers and hanging decor, as well as started making the base and adding beads to the weave.

23/2/2023

Added lights and attached the feathers around the base, adding more strings of beads for more color. We added two sets of fairy lights because we thought one wasn’t bright enough.

The feedback we received:

Hiding the battery packs was prominent in our feedback; we can improve this by adding feathers around the battery pack to make it less visible.

My sketch of our idea:

Define and Inquire

This engineering project is designing and creating a product that converts energy, me and my partner Hana wanted to create a useful product while making it look aesthetically pleasing.

We agreed a lamp would be a great addition to anyone’s room. Our dreamcatcher lamp emits soft light, making it ideal for those who want to read quietly without disturbing their roommates, sometimes, the big light in your room is too harsh, straining your eyes, so this lamp provides soft illumination while setting a calming mood. You can hang it above your desk for late-night cramming, next to your bed for reading and catching your nightmares!

Doability:

Taking into account we only had 5 lessons to complete our product, I found this video on how to create a easy dreamcatcher,

Materials:

• feathers (white or brown)
• suede lace
• metal ring
• wire
• beads/charms
• rope

Taking into I found this video on how to make a DIY dreamcatcher, it seems easy enough and shouldn’t take too long to make.

Pros

• easy to make
• demonstrates energy transformation efficiently
• decorative
• useful

For my invention, I decided to base it off of a temperature gun, there is a trigger to activate it and hold to turn it off/on. There is a screen at the back where you can see what foods are nearby and how to get there, it also shows a map that directs you and is color coded. it is convenient because there is a hand hold and is fitted so it will fit your grip. It is quit small so it can fit into a pocket or bag

In product design class this year, we had to make a  LED light-box. Which was us designing a place that mattered to us and cutting it out onto wood and adding LED lights. We first planned the layers on a sheet of paper, then copied them onto Adobe Illustrator, then sending them to a laser cutter which cut the layers out on wood. Each of us then painted our layers and glued them into a light-box (which we also made) and added LED lights. The place where I chose for my light-box was Japan. I chose Japan because I’ve always wanted to go to Japan and I have friends there.

I learnt a variety of different skills when making this project. I learnt how to make shapes on Adobe Illustrator, image tracing, inserting, and making specific size shapes. The biggest challenge for me was using Adobe Illustrator because I am unfamiliar with creating digital art and it was a new experience for me. I also improved on my art and masking skills. Masking is when you tape a bit of the project and paint the other parts, the tape is for keeping parts of it clean and unpainted. The painting and gluing part was the most fun for me because I had some experience with it before so it was easier.

If I could improve on anything it would be the LED lights because I glued it a little weirdly and it took up too much space. Next time I will cut parts of the lights off and plan where to glue it. This time I glued the lights too close to the edge of the wood, so the wood piece cover had a harder time fitting on and maybe make them less visible.
