We’ve seen (and constructed) any number of intervalometer projects, using pretty much every tool available (remember that calculator-powered intervalometer?). They all accomplish the basic task of taking a photo at a constant interval, and many pack in extra features, however the ‘worlds smallest intervalometer‘ design by Achim Sack stands out for it’s size- or lack thereof.

Using a microscopic PIC microcontroller and some equally diminutive surface mount pats, Achim was able to put together a functional system about the size of a match head. Impressive!

Note: We incorrectly attributed the design to Udi Tirosh, who wrote in to tell us about the project. The post has been updated to mention the correct maker, Achim Sack.
