Miniature alphabet that you can squeeze just about anywhere
When adding small text to a laser etched design, you want to make sure the font you choose will be legible.
This tiny stroke-only alphabet is available to download from the Ponoko Showroom.The free file contains the entire alphabet plus punctuations, brackets and a few other randoms. Characters are only 1mm tall. Any smaller and you will start to loose the inside of characters like ‘A’ and ‘B’ using the heavy vector setting.
On a light wood like the bamboo the light vector setting seems to work well; while the heavy setting on plastics allow you to paint fill to improve readability.
This character set was based on the free pixel font “Wendy” which you can find on dafont. Wendy was used by Stroke-Only Font creator Josh as an initial guide when laying out the line segments. Unlike the pixel font, for this example, as many line segments as possible are joined to allow easy scaling up to larger sizes.
It is worth noting that these are only grouped lines, so you’ll need to manually place letters onto your design one by one.
Using a mini font like this is worth a try if you want to inexpensively add tiny part numbers or a website/email address to your designs.
If laser engraved fonts are your thing, the Evil Mad Scientists have a great Inkscape extension that is enables even more versatility.
iPad app makes it even easier to design for laser cutting
When we first heard about the iPad app Sketch It Make It, we were pretty excited. Now that developers Blank Slate Systems have released their clever drawing app to the public, our fingers are really twitching!
Sketch It Make It is able to rapidly transform even the wobbliest scribbles into neat geometric forms, and have them ready to export for digital manufacturing almost instantly. Whether you are laser cutting, using CNC milling or 3D printing there has quite possibly never been a faster way to turn ideas into tangible objects.
Here at Ponoko, we are very serious about bringing laser cutting to the masses. So you can well imagine that our fingers are twitching with excitement at the potential of Sketch It Make It.
Developed by Blank Slate Systems, this clever little iPad app is all about quickly and easily generating files for digital manufacturing – particularly CNC, laser cutting and 3D printing. All it takes is an iPad, a finger to poke at the screen and an idea that is bursting to get out.
As is shown in the teaser clip above, your wobbly scribbles are magically transposed into neat geometric forms almost instantaneously. There are also a number of clever ways that the accuracy can be further refined down to a precision that will have a file ready for the laser cutter in no time.
Sketch It Make It hasn’t been made available to the public yet, but if you like what you see, sign up at the source to be notified when the app is released.
DIY Kerf measuring tool refines your laser cutting precision
Although it isn’t critical on all laser cut projects, for anything with parts that fit or slot together, kerf is something that is worth paying attention to.
It may sound like a Jim Henson creation – but kerf is in fact a very real technical term. Kerf refers to the gap that is left by the cutting device – in our case, the laser beam in a laser cutter. It’s usually more of an issue when laser cutting in wood, but will also come into play when laser cutting acrylic and other materials.
Open source enthusiast Dave Chamberlin has come up with a nifty device that can be used to accurately measure the kerf of a laser cutter. The simple cutting pattern has been uploaded to Thingiverse, and includes instructions on how to measure your kerf etched right onto the device itself. Here is what it looks like:
Follow the source link below to download the file and try it out on your own laser cutter. You can also discover what else Dave is up to in his open source maker crusade over at Takeaway 3d Tech.
“Meticulously illustrated tools celebrating the tinkerers and the doers: those who build, repair and create.”
Whether it’s the finely tuned measuring devices that ensure every dimension is just so, or the brute force of over 20 different hammers and mallets, somewhere on this illustrated panel will be the tools that enable you to realise your creativity.
Vintage technical publication still grooving after all those years
Before we had those nifty little electronic transistors to build nicknacks and devices out of, machines and the designers behind them relied on mechanical precision to perform tasks. Bringing to light the 1868 publication by Henry T Brown, 507 Movements reveals just how ingenious some of those mechanisms can be… and how relevant they are for today.
Even better than simply a trip down memory lane, this magical repository is just itching to be applied in some 21st century laser cutting projects.
In previous posts, we have taken a look at online 3D mechanical resources and the very handy Gear Template Generator that help to de-mystify mechanical devices. Both of these tools help to get gears working right, but what if you need a little help figuring out which gears or mechanisms to use? That’s where 507 Movements shines.
The movements are represented in both static and selected animated drawings that are kind of hypnotic yet educational at the same time.
To demonstrate how nifty geared mechanisms can be, we’ve included an impressive video after the break (assuming gears are what gets you groovin’) of some creative cogs in action. (more…)
As wonderful as CNC milling machines are, they aren’t exactly portable. Material has to transported to and from the location of the machine, and it has to fit within the work area. The Handibot is small enough to bring with you to a work site, and it can be placed wherever it’s needed on material of almost any size.
The Handibot is something between a traditional power tool and a CNC mill. It’s a power tool made smarter with a lot of help from apps and digital fabrication techniques. Learn more about it and get one for yourself on the (already) fully-funded kickstarter campaign. (more…)
The future is looking solid for rejuvenated browser-based modeler
Fans of the 3D modelling app Tinkercad are turning their frowns upside-down with the big announcement that the company is back in action, and we’re certainly getting excited… because Tinkercad has been acquired by Autodesk.
What exactly does this mean? Well, not only is it great to see Tinkercad back in action; but with the might of this industry juggernaut behind it, Tinkercad looks to be locked into a secure future as elements are slated to filter through into the innovative suite of 123D apps and more.
Tinkercad’s revolutionary Gen6 geometry kernel played a significant role in sealing the deal with Autodesk. The strength of this browser-based solid modelling utility has already proven to be a hit within the Ponoko community. One of the notable success stories of the Ponoko API, Tinkercad makes generating SVG outputs that are ready for laser cutting or 3D printing so easy, it is literally child’s play.
With Autocad at the helm, the Tinkercad free account now has unlimited designs and full import/export functionality, making it that much more appealing to new makers and educators.
“..we have supercharged the free plan. You can now create unlimited designs, all import and export functionality is enabled and ShapeScripts are turned on for free accounts.”

Easily find software for your Raspberry Pi or offer your own creations.
The Rasberry Pi foundation has launched the Pi Store, a one stop shop for software, tutorials, games, and useful code for the Raspberry Pi. The idea is to provide an easy way to to find great software and distribute your own, thus making it even easier to get started. At launch, the store had 23 free titles and 1 paid, commercial program, so the venue is definitely favoring free sharing, at last so far.
