Let there be Light!

This week was our third and final session at the FabLab in which we added conductive thread and LEDs to our embroidery project. I was excited to use conductive thread and review circuits because I have taken an ECE class before and was fascinated by circuits. It’s neat to have my previous knowledge apply in areas I would never expect (ECE knowledge with a creative/ arts project). We started out the class by drawing out designs and figuring out where the conductive negative and positive thread would go into the design. This was important because you could not cross the negative and positive threads and it’s a lot easier to visualize by drawing it out than guessing where the path should go while sewing.

We then sewed the individual sides of the circuit. I did the negative side first and then the positive side. My design halfway through changed as I decided I only wanted to incorporate 1 light in the plane instead of 2 LEDs. One big lesson I learned was that you absolutely cannot have either the positive or negative side touching the other thread. After finishing hand-sewing, I tried to turn on the light and it wasn’t working at all. This was because the negative thread was touching the metal that the negative current goes through at all so the circuit was being shorted. I then hand sewed the negative thread down so that it would not interfere and it worked well!

I had an extra embroidery hoop at my house, so I decided to have this separate from the box we made in previous classes and use it as a small wall hanging. I’m happy with how it turned out and excited about the new skills I gained through this project. Unfortunately, it looks as if the storage on our site is full so I didn’t get to upload a photo but you can imagine it from my previous post!

What’s next?
We are starting to put in more time on our final projects at this point in the class. I went into the FabLab for consulting open hours on Thursday in order to gain more knowledge about the sensors the FabLab has and their experience with hydroponic farming. I talked to Brandon, a sensors expert at the lab who has also made a hydroponics window installation so he helped to clarify many details of the project and I am sure he is going to be a huge resource for us.

  1. Hi Helen,
    I think its pretty cool that you were able to use previous experience from a class and apply your knowledge of circuitry to the project we did in class. I also have tons of prior experience with circuits just from messing around with electronics as a kid so that part of this week was super easy. As you mentioned, the tough part was definitely sewing the circuit and making sure nothing touched. I’m happy that you figured out a way to fix your issue.
