Helping hands are a common soldering aid. These inexpensive devices usually have a substantial base, a pair of alligator clips to hold a workpiece, and sometimes a magnifying glass. [Yonatan24] (who happens to be 13 years old) built his own set using a siren horn as a base. Lately, however, he decided to enhance it quite a bit to use Gorillapod arms and incorporate a solder cleaning and a variety of other features. Of course, there is a magnifier along with a solder waste collection bin.
The build is well-detailed, although since [Yonatan24] salvaged some of the parts, you might have to make adjustments to match the parts you use. The Gorillapod arms are from a cheap tripod, but a lot of the material was left over or stripped from junk (like the lead weight).
We’ve seen workbench PCB holders before (including a 3D printed one), of course, but you have to admire the look of this one, as well as the overboard set of features.
Whether you have shaky hands when working on tiny components, or just need more control and flexibility, we think this “third hand” gripper using coolant hose is an ingenious solution compared to the little metal ones you can buy.
Not surprisingly this isn’t an original idea. In fact, Sparkfun actually sells it as a kit. That being said… it’s rather expensive — especially when you can build [Frank Zhao’s] version for less than $15.
He’s using a cutting board, three machinery style coolant hoses, and a handful of fasteners from the hardware store. You can use the accessories from a regular metal third hand, but [Frank] also shows us how to recreate them using a few washers, some steel strapping, and a wing nut and bolt.
[Mr. Zhao] is no stranger to Hack a Day either — we’d almost call him an inadvertent contributor we’ve shared so many of his hacks! Just take a look at his tiny USB business card, his awesome LED pocket watch, a detailed reflow oven build, or even his IR based augmented reality setup.
