SparkFun Third Hand Kit


SparkFun Third Hand Kit


SKU: TOL-086 - Mfg Part Number: TOL-11784


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. Don’t have enough arms? We sell the Flexible Coolant Tubes and SparkFun Third Hand Parts Kits separately as well.

Assembly Note: During assembly, we recommend soaking the tips in hot water (coffee/tea hot, not boiling) for about a minute before attempting to separate the nozzle from the tube. This will soften up the plastic a bit so it does not break while being removed or popped into place.

Please Note: SparkFun provides a portion of this sale to Ryan for inspiring the design with his Instructable.
