Open Source Laser Cut CT Scanner

Taking a DIY approach to high tech imaging

Providing the magical ability to scan not only the surface, but also to reveal details of the insides of an object, the CT (computed tomography) scanner has quite literally changed the way we see ourselves.

Modern CT scanners are frightfully expensive and are usually found in hospitals but Canadian-born Peter Jansen has built one himself out of laser cut wood.

“After seeing the cost for my CT scan, I decided it was time to try to build an open source desktop CT scanner for small objects, and to do it for much less than the cost of a single scan.”

With a design quite similar to the early commercial CT scanners, Peter’s device began as a quarter-scale laser cut acrylic version that he whipped up in a single day.

He then used this mockup to help refine the design, under the watchful gaze of a friendly house cat. (more…)

Prototyping robot legs with a laser cutter

OFFRobot design iterations resolved using laser cutting

Responding to the tempting possibilities posed by the Hack The Arduino Robot challenge, the OFFRobot is a neat little walker designed by John Rees from the UK.

He’s documented his development process and thoughts along the way, from design of the walking mechanism (including inspiration from Disney Research and the ever-impressive Strandbeest) through to various stages of laser cut and 3d printed leg assemblies.

One interesting point to note is that John’s prototyping went from laser cut cardboard in the early stages, on to laser cut plywood and then 3d printing which came into play once the design was more resolved.

With the deadline of the competition looming, he went back to laser cutting in acrylic for the final burst.

“I did more 3d printing. It gave me some great, really solid and light pieces but I left it too late to print everything, so I will revert to laser cutting once again!”

By ‘reverting’ back to laser cutting for the robot’s legs and gears, John was able to achieve reliable, accurate and tangible results really quickly. That’s one of the major advantages of laser cutting – the unrivalled speed and precision.

Here’s a look at how the OFFRobot mechanism works:

Giant laser cut cardboard velociraptor

Dinosaur costume roams the streets

Meet Felix. As you can tell from his gentle gaze, Felix is a friendly dinosaur and he loves to head out for a leisurely stroll.

Originally conceived (and worn) by Lisa Glover while exploring Industrial Origami as a part of her university studies, this jaw-dropping laser cut cardboard costume deservedly won her first place at a Halloween costume party in 2013.

The response to her 15 foot long wearable creation was so overwhelmingly positive that Lisa decided she had no option but to share it around. So she set out to re-engineer the jurassic costume into a form that is more manageable, and which is now the focus of a successful Kickstarter campaign.

Eager, cashed-up backers can get their legs into a giant velociraptor suit of their own, but for the rest of us there are some neat smaller rewards on offer.

Watch Lisa and Felix out for a stroll, and discover more at KitRex or on Kickstarter.

Etch A Sketch controls on a laser cutter?

Arduino-based modification turns laser cutting into a hands-on affair

Just in time for International Arduino Day, this fun project from Just Add Sharks really has our fingers twitching.

Imagine controlling a serious laser cutter with the dynamic ease of an Etch A Sketch. Having first toyed with the idea years ago, Just Add Sharks have finally followed through and attached a fully functional Etch A Sketch controller to their laser cutter. Talk about dreams coming true!

Complete with authentic twiddly knobs and retro-Etch styling (all laser cut, of course) the modification uses an Arduino Pro Mini to bypass the machine’s existing wiring.

Click through for a video of the controller in action, where you can see the different functionality of either Etch or Cut being demonstrated.

Foldscope laser cut microscope

Ingenious optical device folded from a single sheet of paper

With diseases such as Malaria still causing serious trouble across the globe, there is a real need for major change in the way fieldwork is carried out.

Researchers at Stanford University’s Prakash Lab have developed a laser cut microscope that costs just 50 cents to produce and boasts performance that rivals standard lab equipment.

At the heart of a process that has been dubbed ‘Use and Throw Microscopy’, the laser cut Foldscope is so cheap to make that it can be considered a disposable device. The origami inspired pattern snaps out of a single sheet of paper and easily assembles in minutes.

“It was a hard challenge thinking of making the best possible instrument, but almost for free.”
