Accelerating Raspberry Pi 4 applications

Raspberry Pi 4 performance heating measurement

The Raspberry Pi 4 was released and it has finally enough memory to run Chromium effectively. With the addition of an USB 3.0 controller, this little board can now run programs off an external SSD really fast. However, for anything other than a desktop replacement, this upgrade may prove quite expensive relative to the Pi’s price.

Since most of the Pi’s I know live in a secluded place having no monitors or keyboards attached and will execute a single codebase for their entire lifespan,

Smart Lights

Since it is Christmas time and the entire city has become more festive, we thought of decorating our lab a little. And what better way to do it than with a “small” and “simple” project?

The goal: to make the prizes shelves as shiny, colorful and smart as possible.

For doing it, we have used the following:

  • Adafruit Neopixel Stips
  • Arduino Nano (seemed like the fasted approach – proven wrong meanwhile)
  • Mini MP3 Player with SD card (add some musical background)
  • Mini speaker to connect to MP3 Player
  • Joystick module
  • ESP8266 (yes,
