Single-laser tech prints color graphics on metal

Although it’s already possible to create colored images on metal surfaces using lasers, different types of lasers have to be used for different effects. Now, however, Russian scientists have developed a method of producing multiple effects using one commercially-available laser.

Led by Galina Odintsova, researchers at Saint Petersburg’s ITMO University were able to change the “processing parameters” of the laser, allowing them to control how much it heats a metal surface over a wide temperature range. This, in turn, makes it possible to produce color images in three ways. None of … Read More → "Single-laser tech prints color graphics on metal"

Bi-fuel hybrid camper van drives 1,000 miles and camps on pure battery power

A safety cone-orange Mitsubishi 4×4 camper van would typically be showstopper enough for any motorhome expo booth, but Campers Scotland came out blazing from both hands at this month’s Scottish Caravan, Motorhome & Holiday Home Show, where it also debuted the Eco Explorer. Less rugged but still a 4×4, the hybrid Eco Explorer offers low fuel consumption and a self-charging battery system to keep the lights on and cooktop firing. An LPG option gives it three drive-power sources and up to 1,000 miles (1,600 km) of range per fill-up, while a deconstructed kitchen and sliding rear bench make it a capable everyday … Read More → "Bi-fuel hybrid camper van drives 1,000 miles and camps on pure battery power"

A programmable 8-bit computer created using traditional embroidery techniques and materials

The Embroidered Computer by Irene Posch and Ebru Kurbak doesn’t look like what you might expect when you think of a computer. Instead, the work looks like an elegantly embroidered textile, complete with glass and magnetic beads and a meandering pattern of copper wire. The materials have conductive properties which are arranged in specific patterns to create electronic functions. Gold pieces on top of the magnetic beads flip depending on the program, switching sides as different signals are channeled through the embroidered work.

Let'€™s face it: We'€™re addicted to SRAM. It'€™s big, it'€™s power-hungry, but it'€™s fast. And no matter how much we complain about it, we still use it. Because we don'€™t have anything better in the mainstream yet. We'€™ve looked at attempts to improve conven...
