Binary Burst Clock demonstration

Clock reads 12:54

I finally got around to taking some pictures and shooting some video of my assembled clock project. Above you can see it displaying time. Minutes are tracked by the blue LEDs in binary code. Each spire has three digits, when the inner and outer digits are lit it shows a binary five and the next spire starts counting. Hours are displayed as a red LED corresponding to the positions on an analog clock. Here it is 12:54.

After the break you can see the video of the clock in action, as well as a¬†description¬†of what went into the build. You’ll also find some close-up pictures and a bit more info.

Binary Burst clock concept

I’ve been working on a new clock concept and am far enough along to start sharing some details about it. I call it the Binary Burst. The latter is because I was inspired by some vintage starburst clocks and have settled on twelve spires as a reminder of that design. The binary moniker is because the readout will utilize binary code.

The illustration above shows my intended design. The time shown is 8:22. Each spire reads the minutes in binary shown as three bits made up of blue LEDs. The hour is noted as a red LED on the corresponding spire. If you saw the previous post about balancing the LEDs you may have figured out that the middle LED is a red/blue bicolor, with the rest being single blue. They are 5mm diffused packages that appear cloudy white when not illuminated. There should be some room for alternate display modes, but I’ll need to get working hardware in hand before I figure that out.

I spent a large amount of time over the Christmas break designing the circuit and laying out the board. This evening I ordered parts for four clocks. When they arrive, I’ll check that the footprints work and send the files off to a fab house for manufacturing. This is my first professionally fabricated PCB and I’ve put a lot of extra time in to make sure the design is up to snuff.
