Beautiful display is both new and old
For High-resolution LED bargraph
Studio 449 designed the display as a replacement for a nixie tube, but the design does things that nixies couldn't. It is a simple, well-documented design so it is quick and easy to create some beautiful results. As with most displays with higher current demands, care must be taken to ensure that power and data lines are stable. The LEDs are bright, so depending on the design, a diffuser/filter may be needed.
