Turn that Pi Zero into a Streaming Camera, Step-by-Step

What makes [mwagner1]’s Raspberry Pi Zero-based WiFi camera project noteworthy isn’t so much the fact that he’s used the hardware to make a streaming camera, but that he’s taken care to document every step in the process from soldering to software installation. Having everything in one place makes it easier for curious hobbyists to get those Pi units out of a drawer and into a project. In fact, with the release of the Pi…

MRRF 17: True Color 3D Printing

3D printing has evolved to a point where dual extrusion isn’t really that special anymore. A few years ago, a two-color frog print would have been impressive, but this isn’t the case anymore. The Midwest RepRap Festival is all about the bleeding edge of what 3D printers are capable of, and this year is no exception. This year, we were graced with a few true multicolor filament-based 3D printers. The biggest and best comes from…

How to Play the Bass With Marbles

Stringed instruments make noise from the vibrations of tuned strings, using acoustic or electronic means to amplify those vibrations to the point where they’re loud enough to hear. The strings are triggered in a variety of ways – piano strings are hit with hammers, guitar strings are plucked, while violin strings are bowed. Meanwhile, [Martin] from the band [Wintergatan] is using marbles to play a bass guitar. [Martin] starts out…

Silencing a smartphone at night isn’t difficult, but if you have a landline, Arduino can help! Before computer hacking/modding became accessible, the next best thing was to creatively explore the phone system via custom electronics. Though this pursuit, known as “phone phreaking,” has largely gone away, some people still have landlines. As “MolecularD” shows in […]

In this modern age of cellphones, we’ve all come to expect a certain degree of elegance from our portable electronics' battery systems. But in DIY electronics it’s common to find jumpers or switches that brutally disconnect the battery from its host. Or, no disconnect at all and puffy, discharged LiPos lying about haphazardly on the workbench. In my FLiR Pi Cam build, for instance, though voltage monitoring was built in, I left it…
