Based on Neopixel and a special ultra-thin Arduino, it simulates the light produced by chimney flames As every year, the approach of the winter season stimulates our imagination and reminds us that electronics can do a lot, not only concretely (creating automatisms for indoor air conditioning) but also for pleasure and leisure; so here are…
Here we are, eventually the contest has come to an end and after a short consultation we have chosen the winners! Before announcing them, a few words. First of all, thanks to everyone who submitted his contribution. All the works reviewed are great and must be praised, because they represent without exception a hard work,…
Roland Hoffert, from www.eytec.de, submitted us this 3Drag (Velleman K8200 version) hack to improve the z-wobble issue, one of the most known problems affecting the RepRap family printers. Roland identified one of the weak points that could cause the z-wobble in the fixed coupler of z-stepper motor. With the standard fixing, when the z-stepper moves…
Karl Seiss from Austria made a very clever hack to a K8200 3DRag printer, turning it into a CNC drilling and milling machine. We didn’t receive from the author many details, anyway it used Proxxon long shaft drills to have a highly reliable and powerful tool. Moreover, Karl built by himself also a “vacuum support”…
Giacomo Falaschi sent us his Falla3D new printer project: you can have more details on the project by looking to this interview here. Fa)(a is a fully modular and scalable printer, able to print with any material (FDM technology) and entirely customizable in every single aspect and component. Here are some figures: Resolution: X-Y axis…
This is an unusual project submitted by prof. Hesam Hamidi, who built a linear Delta printer by using recycled parts from old scanners and dot matrix printers. This FDM 3D printer has been designed and built in 2013. Here are few specs: Build volume: 200x200x200 mm Footprint: 600×650 mm Print surface: 200×200 mm heated glass…
Alessio Fusi hacked his 3Drag/K8200 printer by replacing the original threaded rod with a trapezoidal rod, assembled with a gearbox between it and the stepping motor with a reduction rate of 50:20. In a short time, Alessio will replace the gearbox too (fully printed with the printer itself) with a 30:10 ratio that, together with…
Richard Tegelbeckers joined the 3Drag 3dprinting contest by sending us his project, a 3D Delta printer named DeltaTrix 3D, under the category 3D Making. The project is based on the fully open source linear Delta printer, power by a 32-bit ARM processor (Arduino). The resolution is high, allowing potentially 25 micron layers, and a special…
When I think about the world that we are now living, I have to (I literally must) think about open source technologies, open source frameworks and products such good that became excellent platforms to build your own distrupting software, or board. We are living the same situation with wearable devices, in such a way that…
Some weeks ago we launched our contest to see what you can do with a 3Drag printer and some results to achieve. With this post, we are showcasing you some cool stuff made by 3Drag fans: you can already find much hacks and mods for this 3D printer across the Internet, and some of these…
Probably, the best use you could do with a Raspberry Pi would be turning it in a full-fledged media center. With some tuning, a Raspberry Pi can become indeed a device that audiophiles will love, or a tiny board that can empower you television to become a 2014-like smart TV. All you need is some…
The last time I wrote about the best hacks available for a board, I had so much to choice between; now instead, writing about Arduino Yún and all of its best hacks, it was difficult to me to find really good projects, because the platform is so young. While Raspberry Pi had a strong community,…
Open-Electronics.org is the brainchild of a world leader in hobby electronics Futura Group srl. Open-Electronics.org is devoted to support development, hacking and playing with electronics: we share exciting open projects and create amazing products!
Open-Electronics.org is not just a container of ideas: it is also a web site lead by a team of engineers and geeks who will take part in the discussions and give support.
Our mission is to become a reference Open Source hacking site with ideas and feedback aimed to enrich the community.
