I recently performed a test build of boards and case for one of my 6 digit panaplex clock kits for SP-353 displays.
The completed clock is available for sale either with or without the displays, please PM for details if interested.
The picture shows the 6 digit version on top of an 8 digit version which is using SP-352 displays.
The cases are made from green tint acrylic with 3D printed corner parts and are finished with matching copper coloured screws at the top and the same again at the bottom for feet.
The clocks require a WiFi attachment for NTP sync and show time/date/pressure/temperature and relative humidity.
The software is written using the Arduino IDE and can be easily modified for different time zones and units of measurement.
There is a 3.5mm jack socket at the rear for the connection of a PIR device.
I have similar designs for 9,12 and 15 digit versions as well as for other displays including SP-151, SP-332 and SP-333, details available at
panaplex.co.uk.
