The circuit is completed but the effect is minimal. I think I mix the water too much or the powder is too low. It’s hard to make it right however, I can make it happened in the final project.
Challenge: The mixture is very hard to get it right. As I do not have the basic knowledge of watercolor or brush.
Experiment with Flexinol
I like how the spring can go back to its original form. This is pretty fun when playing with it. I failed to work on the first try because of the voltage.
Challenges : The calculation of the voltage is a little complex for a beginner.
I created a coaster that uses an existing interaction (putting a glass on a coaster) to close a circuit and complete the lamp. My original hope was that when different glasses/drinks were placed on the coaster, different colors and shapes of light would be illuminated– a modular lamp of sorts.
The circuit works as hoped: the lights shine when (and only when) a glass is on the coaster. But if I were to do it again, I’d use brighter lights and/or a more transparent surface for the lights to shine through. As is, it’s a little dim.

I was inspired by the breathing rhythm from the fading effect. So I made this bird nest style lamp that can help people medidate when they feel really stressed.
I started the process with making the yarn globe:
Soak the yarn into school glue
Wrap the yarn around a balloon
The code part is a combination of the ATtiny exercise (link) and the fading example.
Testing the ATtiny touch sensor
The yarn pom-pom is being used as a touch sensor. When holding it, the LEDs will be lit up with the fading effect. I only soldered two LEDs, therefore, it is not bright enough. For the future iteration, I am planning to use a brighter set of LEDs and also consider making several of them with different rhythms.
Finish your ATtiny circuit and midterms!
