Touchdown! Curiosity lands safely on Mars

By David Szondy

NASA's Mars lander Curiosity has landed safely on Mars. After a 253-day voyage punctuated by a dramatic plunge through the Martian atmosphere, the nuclear-powered rover has reported to mission control that it is on the ground and systems are nominal. The landing occurred at 10:31 p.m. U.S. PDT (August 6, 05:31 GMT) plus or minus a minute. The landing site was near the base of Mount Sharp inside Gale Crater, 4.6 degrees south latitude, 137.4 degrees east longitude. This marks the beginning of a two-year mission to seek out places where life may have existed on Mars – or may yet exist today.

Agora, os Instructables,  Uma Caixa que é qum  autêntico Puzzle...


Mystery Box

fungus amungus

This mystery box is a wooden cube with no apparent way of opening it. On one side there is clearly a square cut into it, but there is no latch, no knob, and no keyhole to try and open it with.

Mystery boxes, how do they freakin' work?

vacuum form an arduino/electronics enclosure

If you have access to a vacuum former, or have constructed a DIY one to use, simply vacuum form a compact case to house your standalone electronics or arduino project.

Building a Parabolic Solar Hot-Water Heater using 123D

ben.chapman

For this project I set out to create the solar equivalent of the hot-water tap on a coffee machine: a solar on-demand hot-water heater.  I was inspired by the functionality of a new software called 123D-Make that makes it easy to build large, geometrically precise forms.  My goal was to build a device using 123D-Make that illustrates the power of the sun and has many practical uses.  I decided to make my solar water heater by creating a mirrored parabolic dish that focuses sunlight to a point, then add copper tubing that runs a thin stream of water through the very hot focal point, creating near-boiling water on-demand.  By creating a way to boil water without electricity or gas, this project will hopefully lead to less Carbon Dioxide emissions and be a net-positive for the environment.

3D printed robotic exoskeleton gives young girl a helping hand

By Nick Gilbert

A two year old girl born with arthrogryposis, a congenital disease that left her unable to lift her own arms, although able to walk, has been given a new lease on life by a 3D printed robotic exoskeleton, enabling her to move freely for the very first time. The exoskeleton, made of a similar material to Lego, was manufactured using a Stratasys Dimension 3D printer so as to create a prosthetic light enough for young Emma to continue walking around freely.


The exoskeleton was based on another piece of robotics developed by the Alfred I. duPont Hospital for Children in Wilmington, Delaware called the Wilmington Robotic Exoskeleton (WREX), an orthopedic apparatus for the arm made from hinged bars and resistance bands that helps children with very little residual strength to move their arms in space. While WREX was able to help arthrogryposis sufferers as young as six, it was built into a wheelchair and was too heavy and bulky for a two year old to make use of regularly.
