PurpleSnowy is a small badge. You can pin it on your clothes or backpack. You can add it to your key chain. It is cute and shiny.
The version 2 of snowy owl uses a dual inverter NL27WZ04 made by OnSemiconductor. Both gates are in use. So it is still ring oscillator, but not the usual hex inverters.
The second version is here. Just power it with a 3V battery and it blinks. Check out the video
Yesterday I have received the PCB manufactured by OSH Park. It is announced at Twitter. Here is it. Snowy Owl is an amazing bird. PurpleSnowy need more love.
