Supplies

• 1x Morse code key (I got a MFJ-550 morse code key)
• 1x Arduino Micro
• 1x Buzzer (CEET120B085)
• 6x Jumper shunts
• 2x Single core jumper wires
• 2x Jumper wires
• 2x 6-32x3/8 screws
• 2x 6-32 nuts
• 4x M3x12 screws
• 4x M1.4x4 screws (optional)
• 4x Rubber feet (optional) (I got these: Rubber Feet, 232 Pieces Black Adhesive Bumper Pads Self Stick Furniture Bumpers Buffer Pads, 4 Shapes for Doors, Cabinets, Drawers by AUSTOR)

Step 1: Code

You can find the code on Github.

Upload this code to the Arduino.

Step 2: 3D Print

You can find/edit the model here.

Step 3: Put in the Arduino Micro

• 1x Arduino Micro
• 6x Jumper shunts

Step 4: (optional) Screw the Arduino Micro to the Base

• 4x M1.4x4 screws

Step 5: Connect the Buzzer

• 1x Buzzer (CEET120B085)
• 6x Jumper shunts
• 2x Single core jumper wires

Step 6: Connect the Morse Code Key

• 1x Morse code key (I got a MFJ-550 morse code key)
• 2x Jumper wires
• 2x 6-32x3/8 screws
• 2x 6-32 nuts

Step 7: Screw the Base to the Top
