I received components for Project Caramel this week:
- STM32F411 Nucleo board (but ended up using a pyboard running MicroPython instead)
- Passive components (resistors, caps, diodes)
- LM358 opamp
I followed a microphone amplifier guide and used MicroPython’s built-in ADC module.
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.
One of the projects I would like to do is make a fun 404 page using some of these technologies. Maybe interactive headlines as well, we’ll see.
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.
