I was recently looking at some binary clocks and I felt like Why not? I have everything to make one and I don't have a clock in my room.
So I decided to build one and here it is. Hope you Like it and maybe build your own.
It's a cool project because it's your very own, unique clock, it's easy to make, it's highly customizable in both size/shape and firmware/functions, it is Arduino based/compatible AND it looks good.
Step 1: What you'll need
- cardbord/wood box(you choose the size)
- DC WallWart 5V out at least 250 mA
- Arduino or Atmega328/168/88/48
- (if not using an Arduino) 16Mhz crystal and caps (the more precise, the better).
- 13x 220 Ohms Resistors.
- 13x LEDs (your preferred color)
- A lot of Wire.
- 3x pushbuttons (PCB mount)
- (optional) 1x LDR (light dependant Resistor) OR 1x Pushbutton (enclosure mount)
- Soldering Iron and solder.
- Cutter/Xacto Knife.
- wire strippers.
- Computer (I guess you have one if you're reading this).
- (if not using an Arduino) USBtiny ISP.
Step 2: Selecting your box
Select your box, remove the back part from it.
if it's a cardboard box, you might want to disassemble it and reassemble it inside out, like I did, that way its easier to paint or, leave it like that and it looks great!
Step 3: Mark your box.
in a cardboard box, I four it's easier to just make some small holes for the LED legs and insert them from the outside, other ways the cardboard will look awful and your LEDs won't be "snapped to grid".
At first, I marked my box on the inside, but later on I decided that I actuallly liked those Grid lines, so I did them on the outside too.
