Summary
- Engineers are always trying to make things smaller, and Mike Roller has created what he believes to be the world’s smallest LED blinker.
- Measuring just 2.4 mm by 1.5 mm, it is smaller than the previous record holder, which was 3.2 mm by 2.5 mm.
- Components included are an ATtiny20 microcontroller, an 01005 LED, a current-limiting resistor and a decoupling capacitor.
- It is powered by a 220uF tantalum capacitor and the programming is challenging as the pogo pins are too large to be used.
- Mike believes that there will be an even smaller version at some point, possibly using the new TI ultra-small microcontroller.
- As always, Hackaday encourages respectful comments on its posts.
