Are you frustrated with the lack of dexterity from most third hands? The SparkFun Third Hand gives you the ability to hold a board between two alligator clips on two flexible arms with multiple points of articulation. The arm’s wide range of articulation gives you access to any angle of the board that you are currently working on, making soldering that much easier. The SparkFun Third Hand also won’t move around while you work thanks to a heavy aluminum base supporting the arms.
Even though we give you two alligator clips for the flex arms, that shouldn’t restrict their functionality to just holding a PCB. Add an LED for better lighting, a fan to keep solder fumes out of your face, or a magnifying glass to get an up close and personal look at what you are working on.
Note: For assembly instructions watch the product video below.
Note: A portion of this sale is given to Ryan for inspiring the design with his Instructable.
Kit Includes:
  • 1x Aluminum Base Plate
  • 2x Flex Arms
  • 2x Alligator Clips
  • 2x Alligator Clip Covers
  • 2x 1" 6-32 Phillips Screws
  • 4x Silicon Bumpers

Jargon buster

Plain-language definitions for the technical terms used above.

alligator clip
An alligator clip is a spring-loaded metal clip used to make temporary electrical connections to wires, terminals or test points. It is useful for quick bench testing, but it is less secure than a screw terminal or locking connector.
LED
A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
PCB
A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
