It is official. MakerBeam is available in a brick and mortar store #Rotterdam. Yeah!! @metaalwinkel @topclamp #Utrecht and #Amsterdam to come.
We made an overview for you with the specifications of our three beams put together. We believe this will be helpful in your choice what beam to use for your project.
Below is the picture and here is a link to a PDF-file.
In november 2013 a guy called Aleksandr sent us an email asking our input for a design problem. He sent us an email with some Sketchup pictures laying down the problem. He also made some sketches of possible solutions.
The brackets he proposes will not be taken into production, but the sketches are great to discuss here. They clearly demonstrate a design problem we often encounter with MakerBeam. In working on our stepper motor brackets for example we encountered the same problem. The problem in short: MakerBeam is definitely small in size!
First the problem Aleksandr had. Aleksander wanted to connect beams crosswise, see below.
He also made pictures of possible brackets that will solve this problem. He was thinking of what looks like a combination of the 90 degree bracket and the corner bracket. We could see his problem. We could also see that this problem could be easily solved by our right angle bracket. Back then we just had received some samples. This helped to explain Aleksandr we were working on a solution. You can see his drawings below and a picture of our solution at the far right.
The brackets suggested by Aleksander make clear it is not easy to create brackets for MakerBeam. Here is an overview of his suggestions.
What is not immediately obvious from these drawing is the problem of space. The corner style brackets leave no room a nut driver. Or, since you do need a nut driver, it is better said they leave no room for the bracket itself.
Let’s do the math. The diameter of the nut driver is 8mm (nut outside dimension: 5,5mm). The width of the beam is 10mm. This leaves for ony 1mm of space on both sides for the material. This is too thin for metal to make a strong corner connection.
The diameter of the screw by the way is 2,8mm (M3).
The right angle bracket is a much simpler solution. It is now available in our shop. Here is a link.
Leaving room for a hex nut driver is something that is overlooked in a number of bracket designs we received. We love to hear ideas regarding brackets and are always looking forward to receive new ideas for brackets. Or for other products suited for MakerBeam (and OpenBeam) for that matter. If you think of designs remember MakerBeam is a wonderful small and lightweight product with the emphasis on small!
Wing type bolts and hinge bearings: available in our webshop as of today.
Wing type bolts
On our wish list it still read ‘wing type bolt’. The possibility to slide in a bracket midway between brackets already fastened was our aim.
When fastening a bracket to a beam the square headed bolts need to be slided into the beginning of the beam. This is not a problem when your project is all clear and you know exactly what you want to fasten. But when you decide to add brackets between other brackets you need to loosen and remove a bracket before you can add another one. This is time consuming and our wish was to come up with a bolt that would make it easier to add screws to an almost finished structure.
We’re happy to introduce the wing type bolt: the rectangular screw head of the wing type bolt gives the possibility to add screws midway. You can insert the screw midway of a beam and turn it to ensure tightening. This makes it easier to add brackets.
The wing type bolts come in a bag of 100 pcs and cost € 8,13.
We came up with hinge bearings to extend building possibilities. Hinge bearings make it possible to rotate 2 beams relative to each other. You can use the standard bearing to have beams rotate around a fixed point or axis. Making a miniature trebuchet now is possible!
Hinge bearings are an assembled product consisting of
– Bearings (10 pieces)
– Copper saddle band clips (5 pieces)
– Axes (6 long bolts in 3 lengths: 3 cm, 5 cm and 6 cm)
– Teflon tape (18 cm)
– Square headed bolts (10 pieces)
– Nuts (10 pieces)
Hinge bearings cost €17,50.
We plan to include a manual to the hinge bearings soon.
Sam Putnam was the one who came up with the idea of MakerBeam. You can find his story on Kickstarter. He thought of all the measurements, bracket types, quantities etc. and had the first batch made.Johan here thought it was a very good product. He backed Sam his Kickstarter campaign. Unfortunately Sam did not take his idea further. The next step, a website: makerbeam.com, remained ‘under construction’ for about three years. In 2011 we created the webshop makerbeam.eu and made makerbeam available here in Europe. We are happy to announce that MakerBeam.com is officially in our hands. It is no longer under construction and redirects to makerbeam.eu.
We innovated the beams and we are planning to innovate the website as well. MakerBeam.eu will pretty much stay as it is. We will renew our webshop on the Makerbeam.com address. So… we will try to avoid it but maybe you will stumble on an ‘under construction’ notice on the .com website again this year. Sorry!!!
It is a great time to be a maker! Equipment to make all sorts of machinery is more and more available for a good price. Sparkfun, Arduino and Adafruit have made a name in accessible electronics. More and more modular systems to construct a suitable framework for your own invention are coming on the market as well. Open source hardware is booming.
There are the systems based on a repetitive hole pattern (Bitbeam, Contraptor) and the t-slot style systems (OpenBeam and our own MakerBeam). Makeblock combines both styles. Leaving repetitive hole pattern systems aside, what is the difference between these open source t-slot style systems?
MakerBeam sells beams that are 10mmx10mm and available in different precut lengths. Longest beam available is 900mm. There is a precut kit available (lengths from 40mm to 300mm). The beams are an extruded aluminum construction profile. The profile is a simple mini T-slot. The beams are black or clear anodized. The plates and brackets are stamped metal. The beams and brackets can be connected with makerbeam bolts. Size used is M3. We do not sell electronics. On our website you can find specifications and a link to Thingiverse. On Thingiverse you can find design files for makerbeams and additional 3D objects.
OpenBeam created beams that are 15mmx15mm and normally available in a length of 1000mm. There is a precut kit available (lengths 30-300mm). The beams are an extruded aluminum construction profile. The profile is an intricate mini T-slot. The plates are injection molded out of a high performance fiberglass reinforced plastic to make it affordable. The beams and plates can be connected with standard M3 nuts and bolts. They do not sell electronics. You can download design files.
Makeblock is an aluminum extrusion based construct platform. The beams and brackets have repetitve hole patterns and a threaded slide combining the two systems widely used. The beams are available in 8mmx8mm and 8mmx24mm in two different colours, blue and gold. They sell several matching brackets, plates and pulleys. There are different kits available, including one that is lego compatible and a kit designed to be used for education. They do sell electronics. According to their website they will be open about their product and release information on their website.
MakerBeam is only just spreading to webshops all over the globe. In 2009 there was a Kickstarter campaign for MakerBeam. This is how we got to know the product. Makerbeam started early but never fully profited from its momentum generated by Kickstarter. Only after MakerBeam.eu was introduced here in Europe it slowly got some attention. We love the size of the makerbeams. 10mmx10mm looks great, almost elegant.
We are working on our product range. There is a servo bracket in the making and a different solution for connecting bearings will be introduced in our shop soon. Brackets, other type of bearings, gears and gear racks are under consideration. The focus here is on ready available products. Manuals are something we would love to add to our product, but are still struggling to make. Kits are something we are looking into as well. Electronics are not on the menu for us though. We want to provide a professional easy prototyping framework that can be used by makers at home or in the workplace. We think MakerBeam is highly suitable for industrial use. The place where the T-slot originates.
OpenBeam started with a kickstarter campaign this year. We already welcomed OpenBeam in April 2012 (see blog post then). OpenBeam is great because it addresses the problem we came across. Since the MakerBeam profile uses the M3 standard we had hoped M3 bolts available in any hardware store would do. We got lucky on a few occasions, but finally we had to resort to making our own 12mm MakerBeam bolts. Nice as this sounds it is not what we aspire. Remember that we are not the creators of MakerBeam. We are selling makerbeam and try to make it available on the market. It is great that OpenBeam tries to resolve this and it will definitely attract customers with its compatibility to standard M3 bolts. Also we expect Terence Tam, the man behind OpenBeam, to come up with other products and manuals.
Now there is a kickstarter campaign for Makeblock. Makeblock offers just about everything. They are good and their goal is to add even more new components. A small production run took place for most of the parts. For these parts Makeblock is looking to start mass production. They are kickstarting from a different point.
Their goal is to provide a full range of solutions. It looks like they are fully equipped to do so. Makeblock looks more finished. Lego is often used in reference to open source hardware. It provides a recognizable standard. Makeblock gives the feeling of being the aluminum lego version. Absolutely wonderful and very appealing but not sure whether it will suit everyone.
Kickstarter campaigns open source hardware
|Makeblock||192||30,000||104,453 (closes end of January 2013)||December 2012|
In the 2009 MakerBeam kickstarter campaign it is mentioned that MakerBeam is thought to be the first open source construction set made available through crowdfunding. It is not enough to run a good Kickstarter campaign. The product needs to be available to customers as well. Things went quiet around MakerBeam for a long time. By making it available people start working with makerbeams and new components or 3D printed designs are being developed.
Makeblock and OpenBeam make better use of their kickstarter campaigns. The open source hardware community is benefiting from this.
It is a great time to be a maker!
With a very special thanks to Low-Tech Magazine and its article titled: How to Make Everything Ourselves: Open Modular Hardware
We added a new hex nut driver to our range of accessories. It is the very first makerbeam branded accessory! We love it. Not just because of the name. That is just a nice touch. We love it because this hex nut driver is suited for both 6mm and 12mm length bolts. It also fits our M3 nuts well.
This hex nut driver, or nut spinner, comes to replace the other hex nut drivers we have for sale. The small hex nut driver and the regular hex nut driver are no longer available in our shop. The small one could not handle the 12mm length bolts we sold. The regular hex nut driver we thought was too expensive.
The new makerbeam hex nut driver, as mentioned, is suited for both lengths. Plus it is available for a good price. The third aspect of this nut spinner we love!
MakerBeam sketchup components are now available on Thingiverse thanks to Berserker.
Here is a link to the site and a first picture of what it looks like.
We are proud of MakerBeam version 2.0. To increase corrosion resistance and increase surface hardness the beams are now anodised. As a bonus it also allows dyeing. We went with black. It looks good, but more importantly could work well in fields that use photography. Next to the black anodised beams we also sell clear anodised beams. This clear anodised version resembles the classic starter kit the most.
It was difficult to improve the profile and still completely stay in line with its distinct MakerBeam T-slot profile and width and height of 10mmx10mm. We think we succeeded. The new design has a thicker core. We hope this will strengthen the beams. The thicker core definitely has other bonuses. It gives you the possibility to thread wire on top to fit a M3 bolt. This will make MakerBeam even more versatile.
Changing the core also made the slides a bit wider. This increases the chances that standard, of the shelf, M3 6mm button head screws will fit. Whereas they just did not fit before.
There is a bit more info about the screws in our blog post from June 14th 2012. Here is a link.
