On one trip to Germany I came home with a good electric clock timer that can switch on and off appliances even with capacity of 2000 watts.
Okay, here is the trouble, while it worked fine in Germany which has current on 50 cycles a second, it could not work with any decent precision on my current at home which is 60 cycles.
I worked out a lot of compensation arrangements, like when I wanted the timer to switch off after one hour, I had to adjust the switch off point at 1.2 hours after.
I even pasted a circular bezel around the clock face with equally spaced digits from 0 hour (10:00) to 10:00 (0) hours.
From reading on electrical literature I learned that there is such a device as a cycle converter, by which a current of one kind of cycles/second in the input will have an output current of another cycles/second.
But it is an industrial piece of equipment that is for me prohibitive in price.
Guys here, any idea to the solution of my problem that will be simple and easy and will just require me to dive into my home collection of junks for parts?
