I have also been working on an open call application for a 20" container at Institute for X - a creative enclave in my hometown. I’m hoping to get a space where I can work on my side projects and have all my tools and materials immediately at the ready.
This also marked the final week of the Sun of Denmark project this time around. Last night we changed the clock and moved to Daylight Savings Time. It’s been fun and challenging doing a side project revolving around writing on social media. Although I didn’t reach a big audience, it was a fun exercise trying to make each daily tweet interesting and significant.
As usual, I also wrote weekly tweets for @SunOfDenmark. I realized that this is the second to last week before going over to standard time, which ends the stream of tweets. It has been a fun experience writing daily tweets and trying to find creative and appealing twists on the emergence of daylight, but to be honest also has become a bit trivial here at the end.
I had hoped to work on Project Caramel this week, but only did a light bit of reading. I happened to stumble upon a thread mentioning that MicroPython’s built-in ADC only reads in the 0.1MHz range, which might be one of the reasons why I’m not seeing enough data. I need much faster data than that, so I will investigate whether I can build my own MicroPython module in C to gain the required speed. Otherwise, I’ll have to move into building my own C application.
I’m getting readouts, but it seems the amplifier circuit needs more work. For some reason there’s a high “ambient” value (noise?) but I have to actually tap the piezo itself to get peaks, but I should only need to knock on the table. As usual with this project, I will keep oscillating between prototyping and reading theory.
I have probably redesigned my portfolio once a year for the past 5-6 years, but never published it. I always get stuck re-writing my portfolio entries or with the website itself. But with my recent success building this website using Gatsby, I felt like I could use the same structure and have it be a small project. I have been unhappy with my current portfolio for a while because of the design and using wordpress which feels clunky and slow.
I ported all my content to the new structure, made necessary design changes, and published it in a couple of days. Available here: portfolio.kevinandersen.dk. I also switched from Google Analytics to Panelbear, a cookie-less alternative that is also free and much simpler to use.
As you’ll notice, my portfolio and this website look eerily similar, and that’s something I will be thinking about how to address. One thought I had is to have the header gradient be sunrise-colors for this site and sunset-colors for the portfolio. Sunrise to represent what’s ahead for me, and sunset to represent my past.
Instead, I started Project Cocoa. I thought the name would be appropriate since the idea is to design a heater cover for friends of mine that renovated their apartment recently. The intention is to design it in laser cut MDF and paint it afterwards, and a fun way of playing with parametric ideas. I got measurements from them, and started drawing up some pencil sketches, and then moved into Grasshopper to try some out.
Next step is to flesh out more sketches. I’m curious about exploring other, less purely geometric principles like magnet fields or physics.
I think about frequency a lot. In preparation for Project Caramel, I read The Scientist and Engineer’s Guide to DSP. Specifically, about Fast Fourier Transforms and how you can use it to go from looking at a signal in time-space to frequency-space.
In the context of interaction design, I think about the frequency of prototype iterations and product releases. During my first five years at LEGO, I have launched two products. In my experience, 2-3 years for product development isn’t unreasonable when developing something that’s both physical and digital. Say I have 30 years of career left, that’s 10-15 products I have left, a frequency around 9 nHz, or 0.28 cycles per year.
One of my hobbies is coffee brewing, and most of the baristas I have met say they serve hundreds of cups of coffee in a single day. As frequency of iterations, that’s 3,170,979 nHz, or 100,000 cycles per year. Not sure what this means or how to think about it, but it’s on my mind.
I have extended the structure so that beyond this blog, but also project pages that I can create for each project. Did lots of styling, built first mobile support, and streamlined the look on the different parts of the site.
The first side project I want to start writing about is Project Caramel. Why Caramel? Working on confidential projects in my dayjob, I’m used to working with codenames. Besides being a fun way to reference what you’re working on, I think it gives freedom to allow the thing you’re working on to develop independently of it’s name. In blogging, I’ve seen it used by Tom Armitage, who I think uses it because of client confidentiality. For these personal non-confidential side projects, it’s about having a way of referencing a project while the idea is still developing.
Project Caramel is an old idea I had while studying. I was curious about creating more sensuous interfaces that allow for expressivity and mastery. Think about how a piano or keyboard key has the notion of velocity and even aftertouch, while a keyboard key is binary. What if the keyboard keys were sensitive to the way you strike the key? Like typing harder would switch to caps?
I want to explore ideas of having interfaces be a natural part of a surface rather than something that’s mounted onto it. Like if the wood itself was the interface rather than a button coming out through it.
First iteration of the prototype I’m building to explore the concept consists of:
My thinking is, by picking up the audio signal from a surface as I interact with it and performing signal processing, I should be able to quantify interactions.
There’s a lot going on here. Electronics, designing and developing the circuitry needed to properly pick up the audio signal. Firmware development, developing the DSP algorithms needed to qualify the signal. When electronics and firmware is up and running, I will move into the industrial design, designing and prototyping the surfaces that explore the design space that I suspect the sensor opens.
For this week, I researched amplifier-, limiter-, and filter-circuitry, and attended a HackChat Event on signal conditioning with Jonathan Foote. It informal yet informative. The format invited a lot of sharing from everyone present, and after the event I had purchased two new books and had 10+ new tabs open with subjects to research.
I also purchased components for prototyping the above circuitry, which should arrive next week.
