Wow, It's been a while.
Here are a few updates:
++The latest design changed into a simpler shape, yet it serves to the concepts a lot better.

++ about the ink and thread: I tried to sew up in longer threads as realized that it was losing heat along the way and wasn't creating the effect I was looking for.

Also the stitching doesn't have to be this tight, which means I will use less thread ( and therefore less power).
== Testing on a lot of fabric, different curing times and positioning of the thread and the ink, I have FINALLY come to a decision. The blanket will be a little quilted, it will carry some normal stitching, but when the input comes through the conductive thread will heat the fabric from underneath and the image will magically appear.
++ I have started building the final prototype: Here's the top part which contains the microphone.

!!++ I have showed the small little prototype to people who are not related with conductive thread and thermochromic inks. They loved the idea of magical apperance. But since that iteration wasn't in a blanket form but a patch of cloth, they couldn't experience the whole project.
Important Setbacks:
It's quite tricky with working such material because many times they decide not to work. Sometime when they sit without working a day, they go back to normal. I guess I have to clean my code for it, because it's such a mess.
The classic problem of power: The batteries are running out very easy. since I can only use 9V, they don't feel comfortable in a wearable or a blanket. Actually I haven't tried giving lower voltage.. Let's see. Worth giving a try.
The name is an issue that I have to solve.
Ahh.. I only wish the final presentation was postponed.. but of course it won't happen.. sigh..
