The Data Port Logics was developed by Michael Erwin.
It’s driven by a Maxim7219 LED driver chip and supports 38 LEDs. Building and design is like the Teeces or CBI.
There’s an updated an even a full digital version available. Check out the related articles.

The biggest obstacle with the DPL are the LED Light Bars.
I found only one source worldwide and that’s Mouser.
