Looking for a unique metering graphic while feeling a bit nostalgic?

Do you remember the 6E5 vacuum tube? You can read all about them here.

Here’s a prototype object created in CircuitPython with displayio on an Adafruit PyPortal Pynt. The code accepts a normalized input value (0.0 to 1.2). A value of 0.0 is represented by a wide indicator band. At 1.0, the band closes. Values above 1.0 show a brightened (overlapped) band.

See the video below and more via Twitter and GitHub. This is the first of planned display widgets by Cedar Grove Studios.
