DIY Time of Use Clock

Every now and then we find ourselves wondering what Time of Use period we are in. Usually this happens just as we’re getting ready to hit start on the electric clothes dryer. So I came up with an ultra simple Do it Yourself Time of Use clock. Here’s how you can make one yourself.

Taking an old wall clock, I popped off the plastic cover and made a circle out of a piece of paper that would fit inside the clock (without covering the numbers). Then I simply marked the hours along the outside edge of the paper and drew some guidelines to allow me to make the overlay. The one complication is that a wall clock is only 12 hours whereas a typical day has 24 hours (damn daylight savings time screwing stuff up twice a year!). To get around this, you simply make two sections to your overlay. In my example, I used the outer ring for AM times and the inner ring for PM times.

It’s only sort of confusing. You can see the two rings in the picture below.

Quick and dirty DIY Time of Use clock. Maybe the kids will let me use markers next time.

Then I begged the kids for some markers but they said I could only use crayons so I just coloured in the appropriate sections based on the current Time of Use winter schedule. Then you just stick the overlay on top of your clock face, close it all up again, set the time and marvel at your ingenuity.

One problem I ran into was that the clock mechanism wouldn’t easily disconnect from the hands for me and I didn’t want to risk breaking the clock. To get around this, I simply cut the overlay and slipped it under the hands. A little bit of tape and it’s all good.

When the Time of Use summer season starts, I’ll just flip the overlay over, beg for crayons (or markers) again and put the summer season schedule on the other side. And that’s an Ultra simple DIY Time of Use clock to stick on the wall beside the electric clothes dryer.
