Project clock – with ic-18 (tube)

 

This are the pictures from my new clock.
It’s the first time I use homemade printed circuit. There are two ways to produce your own printed circuit. I tested both, but the second (exposure and etching the board) is better. The result is fine. One picture shows the step after exposure, the other one after etching.

The vertical board is not so good. Currently I work on a better solution. It’s easy to change the vertical board. I use a frame connector to connect it to the other board.

The technical informations are described already at the iv-18 page. Please look there.
