How To Make a Brushless Motor for Education

Exploring electromagnetism with DIY laser cut motor

laser cut brushless motor

Teaching kids about how motors work can be a lot of fun, particularly when they get to build and experiment on the motors themselves. So when engineer Matt Venn spotted a neat little 3D printed motor, he decided to make his own variation – this time using laser cut components and an Arduino to run the show.

The learning experience

Once all the kinks were worked out, the Arduino was replaced by a few cheap electronic components. This way, students have the opportunity to build the entire setup from scratch, mounting the electronics on a breadboard as they work out exactly what each component does.

The adjustable laser cut rotor has slots to hold different numbers and configurations of magnets, and this can be further extended by cutting custom rotors to suit alternate magnet arrangements.

This is a great project that encourages a hands-on approach to exploring electromagnetism by building a simple DC brushless motor. Consideration has been made to come up with a laser cut solution that can be assembled and studied within the time constraints of a science class workshop.

Matt has provided all of the files and extra info you need to get the motor up and running on GitHub, where you will also find a brief video walkthrough that highlights how the motor and supporting circuitry work.

How To Make a Laser Cut Dremel Chop Saw

Industrialize your mini DIY production line

dremel chop saw 1

Repetitive cutting for projects that require precision parts can be a time-consuming process. The need for consistency and accuracy in making several hundred cuts from small diameter pipes prompted sculptor HTMF Metal Pizza to seriously upgrade his DIY production line.

Why not use a pipe cutter?

The usual way to cut sections from the hobby pipe is to use a pipe cutter, however this tool leaves a small deformation around the inner diameter. Normally this wouldn’t be an issue, but as HTMF’s process requires smooth edges on both inner and outer surfaces, the sections from the pipe cutter are unsuitable for his needs.

Solution: the Dremel abrasive disc

An abrasive disc spinning at high speed will cut with the precision that HTMF is looking for. When controlled in smooth linear movements, the cuts will be quick and clean… so armed with this knowledge he set out to optimise the cutting process to achieve greater speed without sacrificing any accuracy.

“While I tried cutting the tubing free hand, I found I needed a third hand and there was a huge variation in size which required a great deal of re-finishing.”

Introducing the laser cut Chop Saw

The solution was to build a miniaturised ‘chop saw’ mount for his Dremel cutting tool. As well as holding the Dremel and working material securely, the chop saw houses two drawers; one to store Dremel parts and another to catch the pipe sections as they are cut. He also added a scale on the cutting table that aids in achieving consistent lengths with each cut.

See the full tutorial on how to build a laser cut Chop Saw mount for the Dremel multi-tool on Instructables. You’ll find all the files you need for laser cutting including an adapter for switching between the Dremel hand tool itself and the flexible shaft attachment, depending on which version you are using. The thoroughly detailed assembly instructions are also peppered with tips (and supporting pics) on how to best manage the trickier steps will see you up and cutting in no time.

…and if you’re wondering what’s up with this Instructables creator’s screen name, HTMF stands for Having Too Much Fun! 

 

Animated Laser Cut Fox

Playfully pouncing from frame to frame

laser cut fox animation

The inner musings of talented artist Sarah Capon have been brought to life thanks to an animated collaboration with Industrial Designer Benjamin Donnelly.

The process started off with a neat series of drawings that make up each frame of the animation, capturing the motion and physical suspense as the fox steadies itself before pouncing playfully. Sarah’s sketches were then converted and sent to a laser cutter to be etched and cut from plywood, along with a clever support bracket designed to hold the laser cut fox frames in place during filming.

Laser Cut Open Source Apple Watch Band

Introducing a different approach to achieving affordable designer customisations

OpenBand-on-AppleWatch

For those fans of the Apple Watch who like to put their own individual spin on the tech that they wear, the Open Band concept proposes to further accessorise this iconic designer accessory.

Existing currently as an in-progress exploration from Brooklyn-based rapid prototyping specialists Breakfast, the Open Band project has taken cues from the official range of Apple watch bands, and given them a laser cut makeover. The goal was to allow makers and designers with access to a laser cutter (or a service like Ponoko!) to design custom watch bands that are both stylish and affordable using familiar laser cutting materials.

OpenBand-White-on-Watch

OpenBand-Prototypes

“…we attempted to create an open source design file that would allow people to create a unique, low-cost Apple Watch band which could be laser cut from a number of unique materials, such as: wood, acrylic, acetal, etc.”

The time may be right for this project to see the light of day, but interested Apple Watch wearers will have to be patient… with no definition from Breakfast as to when, if ever, the open source design files will be released. Even still, Open Band is a thought provoking example of how laser cutting can further democratize fancy fashions in the world of high-end design.

Laser Cut Cross Stitching

laser cut cross stitch

The crafty, handmade look of cross stitch embroidery has something wonderfully warm and fuzzy about it. While the regular grid of holes speaks of an industrial precision, the contrast of woven yarn introduces a human element that is organic and inviting.

Laser Cut Cross Stitch Inspiration

The pendant above was made by Rebecca from Hugs are Fun as a gift for her dad. Over time, Rebecca has refined her techniques to become a bit of an expert at making all kinds of laser cut cross stitched whimsies. It’s well worth browsing through her website for inspiration, patterns, project ideas and even items to purchase.

How to use Laser Cutting for cross stitching

Cross stitching describes an embroidery technique of tracing out patterns using yarn or other coiled materials. In these particular examples, the yarn is threaded through a defined pattern of laser cut holes to generate the raster-like effect. With a little creative thought and planning, you can come up with many interesting variants based on this core idea.

The material of choice can be any of our usual laser cutting favorites. Bamboo ply, acrylic, metals or even leather and felt will all respond well as substrates for the cross stitch technique.

For versatile cross stitched patterns, a grid of laser cut holes will allow for quirky pixellated artwork or logos. It can also be effective to cut only the holes you need to define the form; leaving the substrate surface bare either to have presence in its own right or as an optional space for further laser etched details.

Can you give your brand a cross stitched crafty twist with the Ponoko Personal Factory? Let us know in the comments below. For more ideas for Agencies and Brands, see the other posts in the series.

How To Make an All-Wooden Laser Cut Padlock

Keeping your treasures safe 

laser-cut-lock

Knowing that your valuables are securely locked away gives peace of mind, whether you are storing the jewellery inherited from your grandma or the secret plans to your Next Big Thing. Perhaps you just need to keep someone out of your private space, or to seal off the cupboard under the stairs from monsters that lurk in the dark.

Whatever the reason is, a lock and key can be handy indeed. So instead of heading down to your local hardware store to buy one, how about building a fully functional laser cut lock of your own?

This simple and clever design from Thingiverse user PArtzzles will prevent prying fingers from finding their way into your box of treasures. The design for the laser cut lock was worked out on Inkscape, and files are available to download so that you can make a version of your own at your favorite laser cutting service. Some makers might like to adapt the lock to further boost its security credibility to a level that will stop thieves in their tracks. Well… that’s the idea, at least!

How To Make a Plaster Cast from a Laser Cut Mold

Giving traditional sculpture techniques a digital manufacturing makeover

lasercutplasterhead1

A plaster cast of your head is a great novelty, but the process of acquiring one has not traditionally been a pleasant experience. Thanks to a post by Koen Fraijman on Instructables, immortalising yourself with a sculpted bust just became a whole lot easier. How did he do it? By using laser cutting!

Scan and edit the 3D file

The process begins with a digitised scan of the subject – in this case, it’s Koen’s own head. A moderate understanding of the program Rhino is required for the next few steps, where a mold is built around the imported 3D scan. This is also the time to include locator holes, so that pins can be used to aid in lining everything up during assembly of the sliced model. Rhino’s Nest takes care of the slicing, and also prepares everything nicely for laser cutting.

It is important to choose materials carefully and make sure the layer height is correct before heading to the laser cutter. Koen decided on cardboard because it enabled a relatively easy cleanup process once the plaster was poured, and the cardboard flutes also give the model an interesting surface texture.

Cutting the sliced model

Once you’ve had all the elements laser cut at your local maker space or perhaps your Ponoko Personal Factory, the mold is ready to assemble. As a bonus, all of the inner segments that make up the void can also be stacked to give you an additional head sculpture!

lasercutplasterhead3

Pour, clean up and then stand proud…

Making plaster can get a bit messy, but there are plenty of tips on Instructables and Koen includes a few handy hints in his post. After a couple of hours, the plaster will be set and it is time to literally unbox your sculpture. Because the cardboard is brittle/soggy (when wet) and the plaster creeps into all the nooks and crannies that it can, the cleanup can be a bit laborious – but the results, as you’ll soon discover, are well worth it:

lasercutplasterhead2

A very distinctive permanent record of how you would look, should you be made of (in this case) corrugated cardboard! Koen’s key innovation of using laser cutting to create a mold for the plaster cast made this process quite different to the way molds are usually taken.

With the ease and accessibility of 3D printing in workshops across the globe, it is good to be reminded that some of the old stalwarts of model making and sculpture are still viable options… even if they have had a helping hand from a 3D scanner and laser cutter.

Introspective Laser Cut Art

Organic laser cut layers come to life

Adno laser cut portrait detail

When an artist has the knack of truly capturing a portrait, the result will often have a commanding presence that engages and challenges the viewer. Andrey Adno’s portrait series In Myself uses laser cutting to add depth and personality with a distinctive visual style that is quite mesmerising.

The portraits are presented across a variety of scales, from life-sized material explorations to an enormous exhibition installation that is illuminated from within.

Adno-1

Light, shadow and the intriguing qualities of translucent acrylic all play a role in supporting the layered laser cut contours to define the form. These physical works show a high level of detail and present a novel interpretation of the artistic portrait.

Adno-2

The changing impact of light and shadow through different material explorations encourages a range of emotional responses to the portrait series.

Fans of street artist 1010 are also in for a treat, thanks to an interesting digital exploration Adno is working on. With a mesmerising organic motion, the smooth forms swirl and blend to expose and then conceal across several layers of material.

What you see in the animation below is a part of a work-in-progress; a “test version” digitally produced using Maxon’s Cinema 4d program. Although this will not become an actual physical artwork, the connection to Adno’s earlier laser cut pieces continues through the use of layers and cutout contour lines.

Laser Cut Cube Reveals Hand Painted Images

A unique image appears on each rotation of this transparent acrylic cube

cube2

There was definitely some careful planning going on when artist Thomas Medicus put together this remarkable laser cut cube titled ‘Emergence Lab’. Upon rotation, a new hand-painted image is revealed from each orientation with a dynamic three-dimensional impact. It really is quite mesmerising… continue reading below for an HD clip of the cube being rotated through all axis.

The cube consists of 216 laser cut acrylic strips assembled into a grid structure. This enables an anamorphic painting to be positioned on each side that is only able to be seen in complete clarity from one specific viewpoint. In order to retain the integrity of the transparent cube, the images have to occupy the same physical space as their counterparts on the opposite side; adding to the complexity of the hand painted designs.

cube-medicus-opposites-1

cube-medicus-collage

By using this method of construction for the cube, it makes the task of applying the images much more straightforward – but also results in unwanted reflections within the structure. To get around this, Thomas came up with a clever solution: fill the cube with a silicon oil that has the same refractive index as the acrylic structure. This gives the visual impression of a solid glass block, as the individual facets and surfaces of the acrylic strips blend away to become almost invisible.

Having a ball

laser-cut-ball

Give a bunch of people something round that can be thrown, caught, bounced or rolled… and within moments an impromptu game will have started. Even the non-sporty types are likely to join in, so strong is the allure of the ubiquitous ball.

This clever flat-packed ball from Instructables user Scientiffic is comprised of only two simple laser-cut components. Repeated and then snapped together with no need for glues or adhesives, it is a neat example of how you can make a robust and functional object from basic elements.

laser-cut-ball-pattern2

What does an object like this do for your brand?

Engaging customers with a physical object that can then become a light-hearted networking tool allows your brand to form a different kind of association at an event. Incorporating the tactile process of assembling the ball, then adding in the element of play either as an introverted solo activity or as a way to interact with others may indeed prove to be more engaging (and therefore more memorable) than the usual event swag.

A vehicle for your corporate identity

The example here from Instructables shows the components of a ball that have been laser cut from wood. Ways to adapt this design could include the addition of company branding as a laser etched detail, or even changing materials to use acrylic in colors that match your company’s colorway. Other options to generate interest and encourage interaction could involve the addition of simple electronics to illuminate the material from within, or add engagement triggers such as sound or motion sensitive functionality.
