Robohand: How cheap 3D printers built a replacement hand for a five-year old boy
Creators make the design public domain to help people who can't afford prostheses.

by Sean Gallagher - Feb 1, 2013 9:15 pm UTC

Not too long ago, Liam had no fingers on his right hand. The South African five-year old was born with Amniotic Band Syndrome, which causes amputation of digits before birth. But since November, Liam has been using a series of prosthetic hands designed by two men living on opposite sides of the planet, using open source software and 3D-printing technology.

Now, those two men—Ivan Owen in Bellingham, Washington and Richard Van As in South Africa—have published the design for Robohand, the mechanical hand prosthesis, on MakerBot's Thingiverse site as a digital file that can be used to produce its parts in a 3D printer. They've intentionally made the design public domain in the hopes that others around the world who don't have access to expensive commercial prosthetics (which can cost tens of thousands of dollars) can benefit from it.

Aarrrbegarbarfar, forgot to Post like a Pirate yesterday. Oh well... Testing the upcoming posting program which actually looks as though it might be useful, and we even get to test it OUT first. The world stands spellbound in the presence of a miracle... :) Seriously, thanks LJ. Having flung the occasional brickbat when you've gotten it wrong, it's nice to be able to toss flowers for a change.

This has to be one of the most sensible posts I've seen yet about dealing with computers and schools (and in some cases even without the computer, see point U). From Scott McLeod's blog, Dangerously Irrelevant... (Note: I'm just quoting a few of my favorite points - click on the link to get the whole thing.)

26 Internet safety talking points
August 16, 2012 by Scott McLeod

For Leadership Day 2012, I thought I would gather in one place many of the talking points that I use with principals and superintendents about Internet safety…

B The technology function of your school organization exists to serve the educational function, not the other way around. Corollary: your technology coordinator works for you, not vice versa.

D You don’t need special policies for specific tools. Just check that the policies you have are inclusive of electronic communication channels and then enforce the policies you already have on bullying, cheating, sexual harassment, inappropriate communication, illicit behavior, etc.

O Schools with mindsets of enabling powerful student learning usually block much less than those that don’t. Their first reaction is 'how can we make this work?' rather than 'we need to keep this out.'

S Unless you like losing lawsuits, remember that students and staff have speech and privacy rights, particularly off-campus. Remember that any dumb decision you make is Internet fodder and has a good chance of going viral online. Do you really want to be the next stupid administrator story on The Huffington Post?

T When you violate the Constitution and punish kids just because you don’t like what they legally said or did and think you can get away with it, you not only run the risk of incurring financial liability for your school system in the tens or hundreds of thousands of dollars but also abuse your position of trust and send messages to students about the corruption of power and disregard for the rule of law.

U Never make a policy you can’t enforce.
