Time Circuits Clock

Time Circuits

A digital clock designed to look like the time circuits display in Back to the Future. The clock will have displays for Destination Time, Present Time, and Last Time Departed, just like the movie, and hopefully the whole thing will sit in a stylish aluminum case. The Present Time display will show the current date and time, fed by a battery-powered Real Time Clock (RTC) chip, and the other two displays will be user settable. The whole thing is run by an Arduino Uno, which is sending data out to 13 display driver ICs and reading in data from the RTC. This is my first Arduino project, and it’s basically a giant blinkenlights device (366 LEDs!). It is introducing me to Arduino programming, PCB layout, PCB etching, soldering, data channels, and working with 7-/16-segment displays and their associated driver ICs. Since it draws a lot of power (almost 4 Amps when everything is turned on), it’s also teaching me about power supply circuits. It has turned out to be much more complex and ambitious than I thought it would be at first, but I’m learning a lot.

Planning

My goal with this project is to create a working digital clock styled after the time circuits shown in the movie Back to the Future. If you haven’t seen that movie, you should.
