Suis-je le seul à apprécier les girouettes sur les MF 77 des lignes 7 et 8 parce qu’ils emploient des afficheurs à palettes (« split-flap displays » en anglais) ? Je n’en ai jamais vu ailleurs ; uniquement sur ce matériel.

Ici, à Place Monge, sur la ligne 7 du #métro de #Paris.

This DIY Split-Flap Display Does Both Time and Weather

With little more than four economical stepper motors, a Raspberry Pi Zero, and a 3D printer, [Thomas Barlow] made himself an awfully slick Smart Flip Clock that can display not only the time, but also weather data as well. This is done by adding a few extra graphics to some of the split-flaps, so numbers can also be used to indicate temperature and weather conditions succinctly. Displaying the time has to do without a colon (so 5:18 displays as 518 ), but being able to show temperature and weather conditions more than makes up for it.

32 degrees and a mix of sun and cloud

According to the project's GitHub repository, it looks as though each split-flap has thirteen unique positions. The first ten are for numerals 0 through 9, and the rest are either blank, or used to make up a few different weather icons with different combinations. A Python script runs on the Raspberry Pi and retrieves weather data from OpenWeather, and the GPIO header drives the display via four geared stepper motors and driver boards. The rest of the hardware is 3D printed, and [Thomas] helpfully provides CAD models in STEP format alongside the STL files.

The basic design of a split-flap display is really quite versatile, and enterprising hackers have been putting delightful new twists on them for years. There has been a split-flap display used as a kind of flip-book animation, and we've also had the pleasure of seeing an entire Tarot deck used for esoteric, automated readings.
