Construction
Spooky Cat was cut out of a scrap of cabinet from the woodshop, which was painted brown on one side and white on the other. The shape was cut using the band saw.
Two white LEDs were hot-glued into eye sockets drilled out of the wood on the drill press.
The LEDs are illuminated with 5v power from the attached USB cable, which was scavenged out of the boneyard.
Current-limiting resistors were calculated using This LED wizard.
Upgrades
- Spooky Cat now lives on the windowsill above the kitchen.
- Spooky Cat's eyes are very bright, which is part of why it's so spooky, however, if anyone knows about simple circuits that can variably limit current, that could be applied to either smoothly or discretely dim Spooky Cat's eyes, it would be a helpful Cat upgrade.
