Today’s microcontrollers are high-speed powerhouses that can do absolutely wonderous things.

Are we seeing more wristwatch PCB swapping projects because more people are working on them, or because we saw one and they’re on our mind? The world may never know, but when it comes to design constraints, there’s a pretty fun challenge here both in fitting your electronic wizardry inside the confines of an injection molded case, and in the power budget to make your creation run on a sippy straw
Want to start your own collection of retro computers, for free? Well graphic designer [Rocky Bergen]’s collection of paper craft models might be the answer.

The completed size of these models isn’t mentioned, but inspecting the PDF file
