Yes, I know, there are already lots and lots of instructables about binary clocks. I wanted to build one for a long time now so with the USB contest in mind, I gave it a go. So if you like this Instructable then please vote for it in the contest.
As the title suggests, the clock is powered via a usb cable. When you disconnect the clock or turn off the computer, it will keep going on its battery but it won´t show the time until you reconnect it or switch you PC on again.
For this project, I made my own PCB´s. I have only made 3 PCB´s yet and all in the last 14 days so I am really proud oft them. Any suggestions about those are very welcome!
