Time for another retro project, this time a wearable - always on - Pong Watch. Inspired by the classic video game, Pong.
Here is the video of it in action.
Step 1: Parts List
Watch casing - Cheap 99p LED watch from eBay. This makes things a lot easier as I didn't fancy designing or building a watch case. I just performed a few mods to it.
Display - Monochrome OLED with I2C interface. Just a few quid from eBay.
Processor - Microchip PIC 12F1840 8 pin Micro Controller from eBay for a few quid.
