David Huerta shared a project he posted on the NYC Resistor blog: Emma-Ohnoes – Sculpture of Buddhist King and Judge of Hell as a Data Center Indicator of a Network Apocalypse: “Every now and then, a particularly hard storm hits an undisclosed datacenter in Virginia where a huge chunk of The Cloud faces off with actual clouds to see which one can keep electricity running through it the longest. …A little red icon doesn’t quite convey the gravity of the sky falling, so I figured the best indicator of cloud infrastructure status would be the Buddhist king and judge of hell, Emma-O (aka Enma-O aka Yama). …If you enjoy using Muromachi-era Buddhist art to let the office know the site’s down, the 3D models for Emma-O, the also-3D-printed base, schematics, and Arduino sketch are freely available online. The Arduino sketch is designed so that any URL you want to set targetUrl to only needs to return anything other than 200 OK in the HTTP response header, so it can also be pointed to the URL of a site directly to see if it’s up or not…” (read more)

Josh Ajima shared: “Yesterday, I shared a tutorial on how to personalize a gimbal for 3D Printing. Today, I was struck by the idea of incorporating the gimbals into a yin yang symbol. I designed and 3D printed the pieces. The original idea is nice but what is really intriguing is how the components of the piece come together to create multiple forms. I like the initial kinetic sculpture but would like to find a way to gently spin the middle ring. Any ideas? I’ve also included a simplified visual tutorial for personalizing the gimbal. It can be used as a stand alone graphic or you can play with the actual step-by-step models in Tinkercad here.” (read more)

Matt Moore shared: “My first true electronic project! It’s custom fan controller for a hutch with lots of electrical components. I have to leave the door open because it gets so hot. So to fix that, I built this, it uses a attiny85 microcontroller and uses a tmp36 temp sensor, which the microcontroller uses to determine how fast to run fans. It was quite a fun experience!” (read more)

Aaron Newcomb shared: “New personal business card test #1 – success! I will have to work on the layout just a bit since soldering this thing up was a bit of a bear. The paper is all beat up from the alligator clips on my helping hands :P ” (read more)

Community Projects from the Adafruit Blog

Instrucables user N.fletch has posted this great project – a handmade watch he calls ChronosMEGA: “I’ve always loved watches; not only are they aesthetic and beautiful, but they are functional, precise and useful. An elegant fusion between engineering and art; two normally opposed perspectives, now joined in harmonic unison. However, all technologies like the dial-up internet, the CVT monitor and the abacus, inevitably will become relics of our past with the advent of advancing technology, and have since become less pragmatic for the typical person to own. Unlike these archaic technologies, the wrist watch still thrives on the wrists of many, standing forever as a testament to one of mankind’s greatest inventions: the measurement of time. I suppose it was inevitable that I would design my very own wrist watch. The name for this wrist watch is the ChronosMEGA, a combination the greek word: chronos for time, and MEGA for the ATmega328P processor used. The [above] video is a montage that saturates 4 months of development in 4 minutes.” (read more)


While racing to complete a print for this weekend on his massive Gigabot 3D printer, Micah Ganske reached out to share about his experiences, to date, printing on one of the largest affordable “desktop” 3D printers in existence. Here is a little teaser along with some photos of his latest printing project…. (Check it out here!)
