Bacterial self portraits by Erno-Erik Raitanen via Gizmodo. I have gathered the bacteria samples from my own body. The bacteria consumed the film surface producing photographic images that are entirely created by a chance. I have been removed from the process but, at the same time, the images are a product of my body; self-portraits.

Steve Taranovich writes: Touchstone, with its first analog power management product, has enhanced such a function with the capability to use supply voltages down to 0.6V while still being able to deliver a 75 mA output current. The device can be used in power harvesting or peak load buffering applications, the LDO may post-regulate voltage buffered in a large capacitor or super-capacitor at boost’s output. Finally, the LDO may be operated simply as an on/off load switch. TS3300 switching regulator coupled with an LDO in same package - [Link]

A Minimal Punched Tape Reader The rig is composed of a Teensy++ 2.0, eighteen red LEDs, eighteen resistors, and a few bits of laser-cut plastic. LEDs are used to both illuminate the paper and sense the holes. The sensor design is based on the classic Arduino LED sensing code. It’s not very reliable, but it’s a fun afternoon proof-of-concept.

Inspire on the pantheon dome in Rome, the installation resemblance a cathedral of light, an art piece where the visitor is immersed in a 360º unique experience completely surrounded with light. The dome works as immersive environment when inside and as large scale sculpture when view from outside. The dome is made out of nearly 1000 spheres and LEDs that are used as a pixel, creating a volumetric environment with infinite patterns and possibilities. The Dome was presented at Coachella Music and Art Festival 2013 in Indio, California.
