As a matter of interest, how long would you like me to talk for? I was
thinking maybe 30 mins?
I was going to bring my presentation as a PDF/ODP on a memory stick.
Presumably you have the technology to make this happen?
Looking forward to seeing you later.

The idea is simple: Design a laser cutter and make the building
process repeatable for others.
Here's the thing. Laser cutters are traditionally expensive ($30,000
to as much as you can spend) and there are a lot of artist, hackers,
architects, designers, DIYers who could do great things with them- if
they could afford one, or even get regular access to one. Pretty much
anybody who is a maker could benefit from a laser cutter.
Unfortunately, turnkey systems are expensive, and there isn't really a
clear and simple way to build one. We can change this: with roughly
six month of R&D time we can develop a laser cutter which anyone can
build, use, and maintain. Most importantly this system will be open
source which means anyone can improve and modify the design.
Everyone should be able to have a laser cutter! Our goal is to design
a 100W machine which is capable of cutting 1/2" (12.5mm) acrylic,
wood, multiple layers of fabric or thin sheet metal.
Laser cutters are a key technology for making things.
Remember when people couldn't make their own videos, CDs or print out
photos? Me neither (at least we try to forget). In many areas of
media, the last century was quite the read-only culture where a few
gatekeepers would sit on the means to produce everything. Not the best
situation for creativity or for people with lots of cool ideas but no
When you look at robotics and fabrication this is still the case. In
2010, a reasonable laser cutter is still well over 30k and therefore
outside the budget of most of us. However, we are at a point where
this can change. We believe we are able to design a laser cutter that
can be built for under 5k (a 100W version) and a budget version (25W)
for under 3k. It would be completely open source and repeatable.
How this will go down
First of all, we need your support! Your pledge is what makes this
project possible. Once our funding goal is reached, the first
prototype will be formulated. With material testing and debugging
underway we can make a solid alpha system in about 6 months. At this
point, start checking your snail mail box for the alpha kit (see
pledges on how to get one).
Once our alpha testers have had a chance to geek out for a few months,
we will launch into beta with the beta testers. Then collaborators.
Our goal is to launch publicly within a few months thereafter,
releasing the project, documentation and schematics to the greater
We will offer the Lasersaur open source system as kits available to
the public as well as offer documentation online for anyone wishing to
build their system from scratch.
Who we are
We (addie and stefan) are alumi from NYU's ITP and more recently
fellows at Eyebeam in New York City. Both are institutions dedicated
to open source culture and experimentation with cutting edge
As individuals, and as collaborators, we have been designing open
source software since 2002, hardware since 2006, and like sharing our
ideas with the bigger community. Our first open source hardware system
was launched in 2007 (CUBIT: the multitouch system, as well as the
later Touchkit, 2008). These systems were covered internationally and
nationally by media such as MIT Technology Review, The Economist, Der
Standard and even CNN. Over the last half a decade, our open source
hardware has been built and used by hundreds of people, labs and
research universities or institutions. We believe that people should
think globally and act locally and the open source movement has been
instrumental for this.
I was kicking around the same idea with a fellow in Austin, TX a while
back but we had a sub-$1000 price target. I wonder if these eyebeam
fellows will be wise enough to use EMC2? I hope so.

For our second meeting we've presentations from Andrew Katz on licensing
Open Source Hardware projects and a representative from Pay It Forward on
Altruistic 3D printing using RepRap.
- Free and open source software is mainstream. Free and open hardware isn't.
Andrew is increasingly involved in open hardware, and considers what, if
anything, is different about hardware which makes open projects a challenge,
and whether it is possible to construct a licence, like the GPL, which has a
copyleft element applicable to hardware.
Andrew Katz is a partner at Moorcrofts LLP, a boutique law firm in England's
Thames Valley and advises a wide range of businesses on free and open source
related issues. He has lectured and published widely on the subject and is a
founder editor of the International Free and Open Source Software Law
Review. Before becoming a solicitor, he trained as a barrister, and
moonlighted as a programmer during his studies at Bar School, programming in
Turbo Pascal. He has released software under the GPL.
- Pay It Forward — Alturistic 3D Printing
Pay It Forward is a movement to bootstrap the thingiverse using RepStrap
machines to print parts to help other people get started with RepRap

Subject: [GOSH] One week left to contribute to GOSH! publication
To: GOSH! - Grounding Open Source Hardware <gosh(a)piksel.no>
here's the link to the provisional GOSH! publication. this version is
pretty rough: we will begin text editing correcting typos in this
version in the coming days.
Layout stats in about 5 days, and we plan to be finished in eight.
So, if you have something to contribute, now is the time!

As Paul suggested there appears to be interest in doing something Arduino
related for June. A few ideas were discussed in the pub last Thursday and my
mental notes for this are along the lines of (corrections and additions are
- Plenty of people doing Arduino intros etc, and so little point in doing
- What's interesting about Arduino is why it succeeded - suggested success
can be largely attributed to community practices etc, and not the tech
- Arduino community has diversity and it continues to grow in this
So, one idea was that we might have someone (ideally close to tinker.it)
talk about the core Arduino approach and perhaps with emphasis on community.
And then have a few other folks talk about derived projects, either from the
perspective of "end user" or project lead or contributor. E.g.:
- concurrency.cc board
I think there is a really interesting story here concerned with why Arduino
has been so successful, and some valuable lessons for new open source
As ever we'd also love to hear of any suggestions for alternative themes
that folks may have, either for June or for subsequent months.
PS. Details for the May meeting should be up on the website later this week.
