Project: Trading card display pedestal 1
I wanted to share some gifts I made for Christmas. I still need to upload the firmware this week, so I have a bit of work to do still.
They are display pedestals for PSA-graded trading cards. The 14-segment displays show the value and population of each card. The displays connect to an Adafruit Huzzah (ESP8266 module). The intent is for the value and population to be automatically updated through a server. There is a nice package on GitHub for scraping the data for the cards, so I will be publishing that data to my server, which the ESP8226 will connect to.
The front is made from Cherry, and the purple parts are all PLA/ PHA 3D prints wrapped in velvet. I had the aluminum machined locally, and the PCBs were made by Oshpark (also local to me). Each pair of displays is mounted on a board with an HT16K33 matrix driver chip.
Let me know what you think; criticism is welcome:)

Looks cool. What are the segmented displays used for? I only see them fully lit or off.
