Raspberry Pi Zero W as a headless time-lapse camera
tl;dr: There are many ways to capture time-lapse videos. But this one is cheap, completely wireless, and mine. If you want to skip the post and go straight for the glory, grab a copy of my Time-lapse app for the Raspberry Pi. Time-lapses transform subtle, slow processes into something beautiful, and often make us…

Intel’s Chipped Chips
Typically when collecting something, be it coins, cars or CPU’s having the most pristine unblemished example is highly desirable.
