Vernier Excavator is an innovative solution for digital calipers that eliminates the issue of dead batteries.
When you store your calipers, they may accidentally turn on and drain the battery. The Vernier Excavator addresses this problem with a docking station that automatically turns off the tool.
How It Works:
- When you place your calipers in the holder, a motorized 'excavator' arm is activated.
- The arm presses the OFF button, preserving battery life.
Universal Design:
- The adjustable 'bucket' position makes it compatible with various caliper brands and sizes.
Easy to Use:
- Simply dock your tool, and the system takes care of the rest.
Required Parts:
- 1 x Arduino Nano (no pins)
- 1 x SG90 servo
- 1 x B103 10k potentiometer
- 1 x slide switch
- 1 x micro lever switch
- 5 M2 x 10mm cap head screws
- 2 M2 x 20mm cap head screws
- Toothpicks (metal pins can be used if available)
- Hookup wire (recommended: Cat5)
- 3 x 10k ohm resistors
- Super glue
- 1mm x 20mm double-sided foam tape
