If you work with surface mount components, you might want an air pickup tool (sometimes called air or vacuum tweezers). You can find inexpensive ones that use a bulb or spring mechanism (like a solder sucker). While these are cheap, they don’t work very well. [Natsfr] had one of these cheap tools and decided to add a proper pump to make it work like a much more expensive tool.
The post is in French, but translation is easy. There is also a video you can see below. The plan is simple: convert a pump into a vacuum source and connect into the pen. Instead of the ubiquitous modified aquarium pumps, [Natsfr] modifies an (even cheaper) pump that he got from an online auction.
If you’re in the mood for something fancier, check out this pick-and-place with a piezo pump.
