Introduction: Kitchen Clock for Design Strategy
This is Kitchen Clock, a must have partner in your road to becoming the cooking connoisseur.
There are two parts, one telling the hour and another telling the minute.
Time is gold, so does food. Passion for deliciousness knows no time, but an excellent taste reveals the need for time.
Having no clock in the kitchen made our team to realize that there should be one at eye level. It must tell time, obviously and look stylish enough to blend in the kitchen.
So, we came up with this (these), the kitchen-friendly Kitchen Clock.
Step 1: Materials (technical Part)
Aside from the plate, there are technical parts. Making is easy. Find the motor and make it spin! Here are the steps:
Step#1: Choose motor. In this case, we chose Nema 17 (3.5v).
Step#2: Wire the motor and test it. In this case, we used Arduino Uno.
Step#3: Find and use codes to test out the motor. The code used for the minute display can be found in the basic example of Arduino IDE. As for the hour display, the code looks like this:
#define STEPS_PER_MOTOR_REVOLUTION 200
#define STEPS_PER_OUTPUT_REVOLUTION 32 * 64
Stepper small_stepper(STEPS_PER_MOTOR_REVOLUTION, 2, 3, 4, 5);
Steps2Take = STEPS_PER_OUTPUT_REVOLUTION / 8.11;
The original source for the code can be found in this link below:
Step 2: Watch Face (aesthetics Part)
We used laser cutting machine for aesthetics. Design your watch display you want, either in Adobe Illustrator or Inkscape. Here are steps:
Step#1: Use shapes tool to make the body.
Step#2: Use lines tool to mark the hours on the clock.
Step#3: According to the lines, put numbers using text input and use rotate function to aline them in circle. Erase them if that is your aesthetics.
Step#4: Color the lines in blue for engraving and color them in red for cut. (This is purely for the laser cut)
Step#5: Adjust the line thickness to 0.001 inch (or 0.072 pts). It means depth.
Step 3: Assemble
Put the motor, wire, and plate together.
Step#1: Prepare some adhesive or something to hold the materials together (with tapes or aluminum wires in this case).
Step#2: Put them together. The watch face you cut out may not fit for the Arduino Uno and stepper motor, so use a plate either made of plastic for durability, or paper if you want easy assemble.
Step#3: Tape all and glue all.
Step 4: Power Up.
Step#1: Add power source, either usb cable directly connecting to a pc or phone charger (5v), or attach 9v battery.
Step#2: Test again and again to see if the angles are right. Hours go by every 30 degrees and minutes by 6 degrees (there will be 0.09 plus or minus difference for each movement, but they do not accumulate in general).
Step#3: If fine with the Step#2, place the clock(s) at your eye level. Enjoy.
