How-To: Set Up a Basement PCB Fab & Use It To Make a POV Business Card

How-To: Set Up a Basement PCB Fab & Use It To Make a POV Business Card

This Instructable from Jared Foster doesn’t just show you how to make his cool persistence-of-vision business card. It takes you through the construction of a circulating etch tank, the modification of a laminating machine to make a stencil applicator, the assembly of a controller to turn a toaster into a reflow oven, and the cobbling-together of a vacuum pickup tool for SMT components. And then you get some practice using all that cool stuff making a POV business card. It even comes with obligatory American Psycho allusions.

Morse For The Hard-Core: Replace Your Keyboard with a Key

Morse For The Hard-Core: Replace Your Keyboard with a Key

Here’s a fairly radical way to motivate yourself to learn Morse, from Australian Ben Buxton. Got to agree with tipster Alan Dove, who described the build as, “a project involving Arduino programming, a mint tin, a USB interface, and International Morse Code, resulting in unassailable geek cred.” The USB key interface is built into a mint tin and provides a dual input port for a standard USB keyboard to access non-Morse characters. A numeric display on the tin displays your coding speed, and tapping out “SOS” without letter spaces brings up the settings menu. Software, schematics, and build notes at Ben’s site. [Thanks, Alan!]
