So we learned all this digital logic theory in college right. Being the practical person that every engineer is, I thought what REAL useful device can I make with this?
I decided to make a binary clock. First it was supposed to only have 24 hours, 60 minutes and 60 seconds.
Then people told me, that's too easy. So I designed it to have 12 hours with am/pm. Also days of the week 1-7. Then I had an artistic friend help me with the aesthetic design portion of it. The pyramid looking shape.
I made a custom acrylic box, had a laser cutter cut the squares out. Got some square LED's and here it is. Its basically finished. Now I am in the process of making a cover to hide those 300 million wires. Have already fixed the two dim LED's you see there.
Also added the following switches: Set minutes, hours, days. Am/pm is set by incrementing hours. Also a general set clock switch, reset all flip flops switch, and power switch. Debounced all the switches. You can see me setting them in the video.
Here it is. If people like it, I can post my schematic. Note to self: next time use PIC microcontroller!!!!!!

P.S. Retched you remember me bugging you about a 1hz oscillator circuit. Yea. Thats why.
Its actually extremely accurate. Does not lose a second as far as I can see. Maybe over a month it will, will test that.
