For many people, keeping indoor plants happy is a task they just can’t get their heads around. The mysterious fine line between care and over-indulgence; occasional attention and neglect… the simple truth is that we don’t all have a green thumb.
With this laser cut arduino-driven project from Instructables user 10DotMatrix, some of the guess work is taken care of. An array of solar panels mounted on 3D printed brackets track the direction and strength of the sun, and then navigate the unit into the optimal position for maximum sun exposure.
Combine this with the clever Plant Friends moisture sensor and you could be well on the way to creating an arboreal cyborg.
A lot of thought has gone in to how to achieve this, so if your indoor plants could do with a techno-makeover, check out the project page over at Instructables.
Ponoko laser cut Kickstarter trains you to fall asleep. Eyes closed, now breathe…
Chasing those Z’s is about to get a whole lot easier thanks to this nifty innovation from Jeremy Wilson on Kickstarter. The Sleep Sensei sits on your nightstand and gently guides you towards a deep, restful sleep.
How does it do this? To some insomniacs, such an achievement may sound like pure magic, but there is some serious science behind the device. Jeremy’s own insomnia saw him trial numerous sleep aids before he set out to use his Arduino skills to sort out their collective shortcomings.
The functional laser cut prototype pictured above is at the core of this Kickstarter campaign, with the final design yet to be revealed. The key technology has all been sorted out already, as can be attested by an overwhelmingly positive outcome from product trials on real sleep-challenged volunteers.
“The Sleep Sensei primarily helps those with sleeping problems caused by stress or an overactive mind at bedtime.”
If you are one of those creative over-achievers who just can’t stop their mind racing at the end of the day (we probably all know at least a few people who fall into that category!) then head over to Kickstarter to discover more about The Sleep Sensei.
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…)
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:
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.
There was plenty of excited chatter when Greg Holloway posted his MicroSlice laser cutter on Instructables last year. Much of this involved people asking “where, when and how can I get one?” Well, the good news is that this diminutive digital manufacturing device is now the subject of a Kickstarter campaign, and the pledges are coming in fast.
The MicroSlice is a nifty little unit. Once you take a closer look, it is easy to see why it won the 2013 Instructables Radioshack Microcontroller Contest. Imagine a laser cutter that sits on your desktop. Not impressed? Consider that it sits on your desktop, and takes up less space than a bowl of cereal. Less space than a takeout container. Less space than a burger with the lot. In fact it takes up less space than the power supply from a regular sized laser cutter.
The MicroSlice is a Build-It-Yourself kit, uses Open Source Software, and can be easily assembled at home by just about anyone.
The MicroSlice can cut paper, and engrave wood & plastic. Kits include an Arduino UNO R3 as well as 97 laser-cut parts and all necessary hardware to get up and running. The laser diode is a 100mw red laser, similar to what you’d find inside a DVD-RW drive. An option is available to supercharge the MicroSlice with a 200mw laser.
With a truly miniature work area of 50mm x 50mm (2″ x 2″) users will be choosing their projects carefully. For bigger projects, there is alwaysPonoko.

As another calendar year clicks over, you may find yourself reflecting on the past 12 months and pondering what the New Year will bring.
Staring into the mirror is one way to indulge in some serious contemplation… and with this interesting project from Instructables user Wolfgang Kahler, gazing at your reflection can have some surprising results.
The mirror has an array of laser-cut discs at its centre, right where the viewer’s face is likely to be positioned. Each disc is connected to a tiny motor that vibrates under the control of an Arduino Uno, with visually compelling patterns achieved in what could be seen as a simple animation.
As you can see from the video after the break, this results in a dynamic interactive experience that is considerably more high-tech than the traditional fun house novelty mirror. (more…)
There are a few examples out there of DIY laser cutters, with people sharing info and tips on how to make your own laser cutting device at home.
One such project comes from Jens Clarholm, and he has put together a neat overview of just what his home-built device is able to achieve as it cuts and/or engraves various readily available materials.
The laser cutter that Jens constructed boasts a 300mW laser diode sourced off eBay mounted in a wooden frame with drawer runners facilitating movement on both axes. Controlling the mechanism is a breeze thanks to an Arduino Nano and Easy Driver combo. (more…)
Using technical expertise to explore – and indeed change – the way that people interact with and experience music is Yale student Lamtharn Hantrakul’s passion. Deep in the midst of a double major in Applied Physics and Music Composition, this latest project is playing a sweet tune.
In a process that goes from raw materials to fully resolved instrument in just 2 hours, the making of a laser cut flute forms the basis of a student workshop that gives new meaning to the concept of being hands-on with your music.
Referred to as a ‘fluterecorder’, the design is modelled on a traditional Thai flute called the Khlui.
The decision to use a laser cutter was made because it is a workflow that is easily accessible to students, as opposed to power tools that require a greater learning curve and level of supervision. An added bonus is that the laser cutter can be used to create custom etchings, enabling each student to individualise their design.
