31. 500-Word Evaluative Post

I don't even know where to begin. But I have to, and I'm grateful that this post marks the end. Cultural Context I know that usually “cultural context” usually covers things like “a western middle class society” or “the artistic sphere in the UK”, but I think that by this stage of the year everyone already knows what an absolute trainwreck this course has been. I’d like to preface this by saying I really appreciate the help I’ve received from my tutor David this semester. But zooming out and seeing the fragmentation of class morale, the growing tribal mentality, and the fact that other students seem to magically be able to get good grades with no visible effort - very discouraging. And I’m not trying to blame others for my own failings, but I personally feel like under different circumstances the work I might have produced would have turned out vastly different. In a wider cultural context - it’s another art project made by a graduating design student for a grade. I don’t th...

30. More Soldering, Current Wiring Setup

Kind of procrastinating but also kind of productive. Mapped out the current circuit that i need to put together, because even though everything's already connected on the breadboard, it's a bit of a tangle haha. Went to the electronics lab earlier today to solder together little circuit boards for the LEDs, so that they could be connected to the resistors and the Uno board more securely.  Also soldered wires to the buttons i just got from Amazon.  Workspace~ Strip boards vs donut boards? Clamped down the buttons  Connected~ My little LED boards. Each one has a different length to match their spots on the heart.  Side view  Back view. The connections are pretty straightforward. The negative side of the LED is connected straight to the GND pin, and the positive side goes through a 220Ω resistor before going to the other pin which will connect to the digital output on the Arduino Uno They work!  Also use...

29. Segue - What are Capacitive Sensors Anyway?

Since I've been facing trouble figuring out how to position the touch sensor in my silicone heart, I started researching how they worked. (Gonna admit that before this I just accepted that it worked and never thought about the how). First place I looked was the manufacturer's website of this listing. I actually bought my sensor from a reseller based in Malaysia.  Details found on the product listing. DFRobot actually has a wiki page for all its products, so that's what I checked out next. Unfortunately this wiki page maily shows users how to wire things up and get started, instead of how the sensor works.  Finally found this site which provided more technical information.  "Capacitive touch sensors fall into two general categories: the mutual-capacitance configuration and the self-capacitance configuration. The former, in which the sensing capacitor is composed of two terminals that function as emitting and receiving electrodes, is prefer...
