This is hands-down the BEST tutorial I have come across to describe how a transistor works and why it can act as a switch and signal amplifier. For those of you who are working with loads that need more current/voltage and therefore a transistor, I *highly* recommend you watch this immediately.
Enjoy 🙂
Woohoo! It’s finals time 🙂 Here’s everything you need to know – email me with any questions. Also, please note that last class, I said your final documentation was due the Thursday after final presentations. I have changed this to Wednesday, May 16 at midnight to ensure I get grades in on time.
1) WORKING PROTOTYPE
You MUST bring your prototype to show – even if it is not working. If you require a specific environment, please email me.
2) PRESENTATION
You will have 8 minutes to present. This includes time for feedback, so structure your presentation accordingly. Your should include the following in your presentation ( in whatever order you like):
3) VIDEO DOCUMENTATION
You should make a short video introducing your project. It should include the title of your piece, your concept, and a prototype demo.
1) BLOG POST
I will assess your project by the following criteria:
Ideation, Concept, and Design
Process + Materials
Presentation
For those of you interested in heating circuits and thermochromic ink, below are some helpful circuit configurations. These circuits were taken from the Building Heat Controlling Circuit workshop at eTextile Summer Camp, KOBAKANT’s How to Get What You Want site, and the thermochromic ink workshop at eTextile Spring Break. Please see these links for a deeper explanation on different types of heating elements and power sources:
This uses a TIP 120 but you can also use a Mosfet IRLZ34N SPBF (they have the same pinout).

Create a post with
1) The next iteration of your prototype.
Use the class documentation format.
2) Your playtesting plan and desired feedback.
To think about: Who will you playtest with? How will you get their consent? What feedback do you want? What questions will you ask? What information do they need to know before starting? How much will you help them during the test? How will you debrief them?
Reading sensor values
Mapping sensor values
Calibrating
1) Human Circuit
2) CapSense Library and example
3) TouchLib (More instructions here)
4) Teensy touch pins
Due April 5: Create a blog post with the following:
Due April 12: Create a blog post with the following:
Documentation of your first prototype. This can be a circuit, physical object, etc. It should include any initial challenges or questions you have.
