13. Skin Electronics¶
Week 13 _ Christmas!!!¶
The last week of this term. Many thoughts related to this week's theme. In parallel, we have to work on the idea of the final theme. Will I be able to fit in on time? But...
Research & Ideation¶
As in every week, researching begins with Fabricademy's tutorials at the assignment Skin Electronics week by Katia Vega. This week we must feel the spirit of the holidays. We have to create a story.
I was impressed by the video below, and I decided to do something similar.
I decided that I will create a similar circuit that will be placed on the hand. Only 2 colors will be used: BLUE and CYAN.
Code¶
For this circuit I modified an existing code. I placed only the colors BLUE and CYAN.
Testing¶
I made some attempts to make the code work. I placed the code and connected it to the computer.
The circuit was going well and I decided to make the hand accessory. I created a pattern, cut the detail from 1 mm thin felt and processed the edge with pearls.
At the end of the edge processing, 2 buttons were sewn and it was worn on the hand.
The code was working fine. But in combination with the ornament (butterflies made of feathers), the blue lights seemed boring. I modified the code in multicolored lights. I also managed to insert the circuit into the accessory. I chose to sew it with conductive thread.
This is what the code looks like with multicolored lights.
This is the schematic of the circuit.
After checking the code and circuit, I assembled Gemma with 2 batteries and decorated the accessory with butterflies. Gema and batteries have sheets hidden in the pocket of the accessory.
Results¶
And here is the result :)
But the theme is skin electronics, and the elaborate glove does not really correspond to the theme. I decided to make some changes in appearance, but not in functionality. I cut the felt layer and placed a colorless film layer.
The code and the circuit remained the same, I just put metallic conductive wires.
