Mega Scope Clock
Thursday, 30 August 2007
I wanted to openly display the Oscilloscope tube, and put the PCB in as small a case as possible. I found that the PCB slides perfectly into an aluminium case from Conrad (522945: Euro-Aluminium-Kuhlrippenprofil-Gehause 165 x 110 x 55 mm). The torroidal transformer is mounted externally. Putting the transformer in a separate enclosure eliminates its magnetic influence on the display CRT (which is very sensitive to magnetic fields), and keeps down the size of the clock. The display is mounted over the case using a metal waste pipe clip (48-51mm), found in a local DIY store. The bolt thread is hidden by an aluminium tube sleeve. I still have some finishing touches to make, but I'm already really pleased with the results. This is exactly the kind of retro look I was after!

Here is a great Scope Clock from Ulf Pambor.
The clock is shown here (left) synchronised (via DCF77), indicated by the arrow between 1&2. A green LED on the case flashes seconds and indicates a good DFC signal. A red push button enters the set-up menu where you can manually set the time and other options.
