#147120 - I confess, the idea with the camping inverter... Responding to: ???'s previous message |
...and the travel back to the USA wasn't meant all too seriously, dear Raghunathan.
Nevertheless, the idea with the inverter is very simple. I have built many years ago such a tiny inverter, which first generated a simple quartz stabilized 50Hz square wave containing a blank out pulse (approximated sine!) and then drove a step-up transformer. Assuming that your clock draws only very small supply current this whole thingy could fit in a tiny enclosure, not bigger than a notebooks mains power adapter. So, the "camping" and the "travel" part was a joke, but not the "inverter" part. Kai |
