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).
