gpiozero is rather good

gpiozero (‘A simple interface to GPIO devices with Raspberry Pi’) continues to impress me. One of its newer features is a pinout guide, accessed by the pinout command:

Raspberry Pi Zero pinout – click through for PDF

I’m trying to resist running it on every generation of Raspberry Pi that I have (B, A, 2B, 3B, Zero, Zero W) just for these pretty displays.

(ANSI console colours captured using script, then fed through ansi2html [from the Ubuntu colorized-logs package], printed to PDF from Firefox then mucked about a bit with in Inkscape)

two-colour EPD displays are so pretty …

rotating tile pattern on Pimoroni Inky pHAT EPD display

This is a 600 dpi scan of a Pimoroni Inky pHAT EPD display. EPDs — electrophoretic displays, aka ‘e-ink’ or ‘e-paper’ — retain their image when turned off, so this Raspberry Pi had no power when I scanned it.

The image I made to fit the display is really small —

It’s a bit of a process making the images with just the right palette in GIMP, but I’m pleased how it turned out. I’d like to be able to write the vector images directly to the screen from SVG, but that might take some time.
