I have used these via the Smart Socket concept which allows you to easily display numbers, letters, punctuation and user defined characters on any number of these tubes. I have used 'smart' sockets for B-7971's as well as ZM1350, SP-101 and now 16 segment LED 'starburst' displays. My clocks display time, day, date, month, year, temperature, pressure, local wind speed and direction, random words and my latest variant also displays the name of a place in the world where it is 'Just After Five!'. There is good support over at the Smart Sockets group and I have a stack of bare PCB's available if you fancy a go. All you need is a PIC16F690, some resistors and MPSA42's and you just squirt serial data to them to display data, define characters, chose transition effects, etc,etc (I'm a bit of a fan - does it show?). There are several transition effects including various fades and wipes as well as a bitwise breakdown and rebuild. All transitions can have their speed defined. I have also 'developed' a controller using a WeMos D1 as well as a Teensy 3.2 (mostly because I am not clever enough to code the whole thing on one WiFi enabled Micro) which does time sync, scrape data from the internet, read temp and pressure, send random words - or now names of places in the world where it is just after five. It also reads a PIR for shutdown of HV supplies when you are not watching (be kind to your tubes) as well as control neons for colons. Ask me anything! - Richard
