This clock is made up of four IV-17 alphanumeric VFD tubes. As it ships, the electronics come in two parts – the base with the microcontroller and the shield with the VFD tubes. The base can support up to four sixteen-segment tubes or twenty seven-segment displays.

It ships with an ISP header for easy software upgrades. If you want to make your own four letter word machine or to experiment with VFD tubes, this is a great place to start.
I received this device fully assembled but it normally ships as a kit. Nearing the menu structure is pretty easy and there is a manual online to make setting the device easier.
A FLW modification is in development to support this feature. Overall – I’m a fan of this little device.
