Shenyue’s Assignment 10

I made these two heating elements below, by hand sewing using stain steel thread and fabric. The first one is a pattern in a line drawing by one of my favorite artists Pablo Picasso, with 8ohm resistance in it.

The second one is a victory sign meaning cheering up, with 11ohm resistance in it.

For both of them, it is good to use 9v battery as a power source, according to the equation. But when I was trying it, it didn’t work very well. The pattern seemed very weak and couldn’t really be seen in the photo. I guess that the problem was probably because the color I used to paint the fabric is too light so it didn’t have room to change much. I intend to try using a darker color on fabric to test.
