I designed this 5-key keypad just for fun and now I'm glad to share it with all who are interested.
I published the sources of Staryu here:
https://github.com/kairyu/staryuAll keys--though 5 keys--on Staryu are programmable. The firmware is based on the famous "TMK keyboard firmware", and the default keymap and fn settings are like the following.
User can customize its own keymap by using
TKG and
tkg-toolkit which are made by me too.
Actually I have no Staryu on my hand yet. Here are some photos by other users.
Prototype PCB of v1.2 and v1.3 (The manufacturer made a mistake so some silk on bottom side of v1.3 was missed)
Assembled with a simple clear acrylic bending case.
Someone also made a simple anodized aluminium case for Staryu.
You may have noticed that there is a RGB LED in the top-left corner of Staryu.
And off course Staryu has full backlight and several light effects.
Here are some other awesome photos:
