It has been a long time since my last post, well, I have been busy and had significantly less time for tinkering.
But back again. Take an old elevator panel, two displays and a Raspberry Pi and transform it into a home information system.
Ingredients and Original Idea
- A really old but massive elevator panel with all the original wiring, the buttons and even the led-matrix displays.
- A Raspberry Pi (of course)
- Two ILI9341 2.2″ TFT panels
- Adafruit’s python library for ILI9341
My original idea was to reuse the LED-matrix from the old panels to display some information. This unfortunately was not possible as these are not ‘normal’ matrix displays but do have some sort of logic built in. Applying a voltage on the terminals (in the middle of the picture) does display the preprogrammed floor numbers in the display. Well, this is not a big issue, TFT displays are much cooler.
Here is an image of the unaltered elevator panel:
