this term we have a choice of a project in design. The teachers had a lot of ideas we could also chose from. I chose one of those so my project is a light up jean jacket. A picture of the jacket without lights is displayed below.
What do I know about the topic?:
I know that I have an idea on how to sew on the LEDS.I also know how the circuit works with LEDS because in term 1 I made a LED mask using a + to – circuit.
what information do I have?:
The information I have on this project is how this project works and how the energy transfers to different parts of the conductive thread then to the LEDS witch makes them light up.
How much do I understand?:
I understand multiple parts about the project like how the conductive thread transfers the energy to each LED and where the energy comes from which is the lead battery cells and how the + and – work. I also understand how the Leds will work.
What questions can I ask?:
the questions I can ask are about the sewing and stitches to sew on my jacket.
Here are the materials i need to do it.
Here is a diagram of the different parts of the sewing machine.
If you follow these six steps nothing will ever go wrong.
1.fabric on start line
2. Foot down
3. left hand hold cotton
4.right hand three stitches
5. swap hands
6. sew slowly
To learn how to use a sewing machine Mrs Watson set up a workshop to help us. first we learnt how to do a straight stitch and did on a scrap of material. Then we learnt how to do a zig zag stitch and again practice on a scrap of material. After that we did a practice project we made draw string bags.
I experienced a few problems. One was that i had sewed a bit to close to the edge so there was a whole.
Here are the steps we had to do.
1. use a zig zag stitch all around the edge
2. iron the fabric then fold and iron again
3. use straight stitch on the bottom of the fold
4. fold the other side and make sure they’re equal then iron
5. fold in half
7. use straight stitch on the sides
8. get string and Platte it
9. loop Platte through
Here is what it looked like when finished.
After the sewing bit was finished we platted string then put it through the bag. Here is a picture of it fully finished.
One of the problems with my jacket i had was that i couldn’t start until my Leds arrived. Here is a diagram of the circuit for my jacket.
before we did that we had to use alligator clips to light up 5 leds. i had it working then it lost connection here is a picture of the circuit.
in this picture there is one working but i still got five working but it lost connection. Here is a picture of my Jacket with the lights glued.
• Which ideas are important?
The most important ideas are making sure my circuit plan is accurate, making sure my is placed correctly so it transfers the energy to.
• What will happen if….?
If the conductive thread is not placed correctly it could make a short circuit which wouldn’t allow the to transfer to the Leds.
• What else do I need to do?
I need to use conductive thread to make the circuit and try to make it transfer the energy to the Leds and make them light up.
• How could I do better?
I could better by being more concentrated.
• Did I solve the problem?
So far i have solved all the problems that i have come across on the way.
• Am I working well with others?
Even though i am not working in a group i am still cooperating well with others.
• Is my plan detailed enough to achieve my goal?
I think my plan is quite detailed and clear.
What can i do with this?
I can present it.
What choices can i make to extend my thinking?
To extend my thinking i can think about it harder and make it trickier.
The next step was to make a pocket for the lily-pad and battery pack to be kept. A picture of the pocket is displayed.
The next step is to make and construct the circuit Here is a picture of my circuit when my positive line is finished and my negative is halve finished.
Here is a picture of my circuit when both the positive and negative line are done.
here is a video of me testing my LED’s.
So far In the process of my project I have learnt: How to program and change the setting for the Lily-pad batch, How to use a sewing machine, How to use the different stitches and what the different stitches are used for.
The next thing i had to do was to connect the lily pad to the jacket so i did that with black cotton on the number i am not using for the settings. A picture is displayed below.
After i connected the lily pad to the jacket the next thing i had to do was to connect the negative to – . i also had to loop around 4 times .and i was doing the setting for 2 so i connected positive to the 2 and loop around 4 times. while i was doing the negative i forgot to flatten my thread. i ended up with a bunched up jacket. A picture of it is displayed below.
I ended up to make the decision to undo the negative not long after that my jacket was finished. A picture is displayed below of the back.
And the front of the jacket.
After realising that i had created a short circuit i had to insulate it with some masking tape s that it would still work . A picture is displayed below.
here is a video of lights working.
The lights use a lot of battery and killed the battery pretty fast so i had to go and buy some more. Here is what i needed.
