A wearable pin of Snowy Owl with blinking eyes.
This is the second in the lines of owl-shaped design. It's an implementation of ring oscillator with inverter gates. The selection of chip is not the usual hex inverter like 74HC04 or CD4049 but a dual-inverter NL27WZ04 in the package of SOT-363. So there is no unused gates left.
There are two different soldermask colors of SnowyOwl.
Note 1 : The package of SOT-363 may be challenging for beginners.
Note 2 : CR2032 battery is not included as the Post Office does not allow it.
Owl is one of my favorite birds. A dual-inverter NL27WZ04 is a different way to implement the ring oscillator.
The use of a dual-inverter NL27WZ04 plus the snowy owl design makes it unique.
