While 7-segment displays are all well and good, they are considered a little old hat these days. this project from [Matt Deeds] brings them screaming into the future, however, Every color is playing under the rainbow.
[Matt’s] The build consists of a PCB filled with SK6812 side-mount LEDs, which are placed in a distinctive 7-segment pattern. Each PCB has two 7-segment digits. SK6812 LEDs can be powered in the same way as the well-known WS2812B addressable LEDs, although they have the advantage of being more stable in color and brightness over a range of supply voltages.
With the LEDs installed, and a second PCB used entirely as a diffuser, except for sections of the solder mask, it's a compact 7-segment solution at just 2.7mm thick. The bonus is that each segment can be set to a different color thanks to the nature of the addressable RGB LEDs. Going too ham in this regard will make the display difficult to read, but it can be used to easily display green, red or yellow numbers as, for example, a visual guide to a numerical range. For making.
It's a great build, and we'd love to see the 7-segment display revisited in different ways - Mechanically too! It takes fewer pins to drive than the old way of doing things in the non-addressable LED era. If you have your own 7-segment neat projects under development, Please tell us,
