Hands free hot air station

In an effort to ease the process of soldering Ball Grid Array (BGA) chips at home [Roger] rigged up a hands-free solution for his hot air equipment.

The main component in the build is an Aoyue hot air rework station that he already had in his workshop. He wanted an adjustable mount that would hold it steady when reflowing parts so he hit Amazon and bought a $14 articulated lamp. After ditching the funnel-shaped shade he bolted a cable clamp to the socket housing. This can be tightened on the hot air wand, with the spring tension of the lamp making it easy and quick to reposition the nozzle. [Roger] sent this project directly to our tips line and we’ve embedded the rest of the project images after the break.

If you’re looking for a more DIY rework solution you should checkout this hot air pencil hack. It uses a desoldering iron, a fish pump, and some metal mesh as a heat sink to put out a stream of very hot air.

Hardware store follow focus

Want to do quick and accurate focus change with your DSLR? Here’s a discussion thread covering dirt-cheap solutions. It starts with a broccoli rubber-band and a couple of zip ties. That being a bit chintzy, the more popular build seen above uses a hose clamp, rubber band for padding, a drawer pull, a nut, and some threaded rod. If you build it, be very careful not to over-tighten the clamp and crush your focus ring! After the break we’ve embedded a video of what follow focus looks like through the lens and what is happening with the camera during the shoot.
