Sometimes the simplest things in life are the most beautiful. [The Tweaker] has soldered an LED circle on the top of an ATMEGA328P chip, and it looks great.
Using nothing more than some solder, wire, 20 x Pico 0402 (1mm x 0.5mm) blue LEDs and an ATMEGA328P (7mm x 7mm), [The Tweaker] managed to cram 20 LEDs into a circle on the top of the chip soldered in dead bug style. The chip is running some Arduino code and is operating on the 8MHz internal crystal, so that manages to keep the part count low. The soldering is done in a spiral so the LED terminals are hooked up to the right pins, but it seems to add to the aesthetics of the project and looks like it would take a really steady hand. Once you connect a power source it displays chasing lights as well as other light patterns.
There may not be much to this project but it does look great.
You might be interested to read, this isn’t our first dead bug Arduino.
