The Works

Here's what's inside. The electronics are on two identically sized boards stacked one on top of the other. The microcontroller, drivers and power supply are on the lower board and the tubes and setting switches are on the top. If you buy the clock as a "module" this is what you get.

The kit contains all the parts you need to make the uncased clock above.

You can see the Schematic and the bill of materials for the kit here. The manual contains details on how to operate the clock.

The Prototype

This is the prototype version of my model 2D3 clock. It was built as a software development platform, and to fix any hardware bugs before having a batch of circuit boards manufactured.
