Not really sure where the motivation comes from for this project, but I assume it had a lot to do with being bored. I remember wanting to make a backwards running clock years ago just to catch people off-guard. Then I read an article about how to get cheap battery powered clocks to run backwards here. So I decided to give it a try.
The only minor problem I had was the clock not having enough power to move the second hand, so it kept skipping as though the battery was dead, despite the fact that it was a freshly charged battery. Then I remembered that rechargeable batteries usually supply less voltage than regular batteries, so a quick battery swap fixed the issue.
I also thought it would be interesting to have the numbers on the clock also the wrong way, so the clock would still be (relatively) readable. The clock that I had also had two guages for Temperature and Humidity so those had to be changed as well. The plan was to make the clock still look like a boring proper clock so I scanned in the original clock face and did the changes in photoshop, matching the font, etc.
After I printed the clock face, I glued it onto the clock and reassembled it. For the first week, it was odd to even look at. For a few seconds it appeared as though the second hand wasn't even moving at all, since it wasn't moving in the direction my brain was used to. Very odd.. Now it is very easy to read and sometimes I have to think twice while reading regular clocks. Most people that come in my room don't notice the clock moving backwards at all.
Anyways, here's some pics of the reverse clock.
