3 Simple Hacks to Protect your Files from Theft, Piracy, and Plagiarism

Angus from Maker's Muse shows how he protects his files from theft, piracy, and plagiarism. He uses watermarks, invisible or hidden watermarks, and hiding a text into a file. All those measures can be defeated but that is just nature of the digital world.

3D Printable DIY Moka Pot Made with Formfutura Volcano PLA

Stefan from CNCKitchen in Germany designed and successfully made a fully functional 3d printed coffee Moka pot. Due to high temperature needed to reach the internal water pressure he used Formfutura Volcano PLA. Do keep in mind that this is a demonstration and not everyday usage object. The pressure build-up in a closed plastic vessel can be dangerous.

DIY Open Source 3D Printable Submersible Glider Drone

Alex Williams developed and built this sophisticated open source submersible glider drone. 3D printed elements are the main components.


Project description:

There has been a breakthrough with low cost autonomous drones and as this capability has matured a wide range of hobby and commercial applications have developed. There are no affordable extended duration underwater exploration platforms and this project aims to address this need. 
Utilising commodity hardware, 3D printed parts and an open-source autopilot, I aim to produce a low cost and versatile underwater glider capable of extended missions of up to weeks at a time. I hope that by having this platform available, it would reduce the cost of underwater projects for all, from hobbyists, amateur scientists to seafood farmers

Vitaprint 3D Bioprinter by IRNAS from Slovenia

IRNAS Institute from Slovenia is developing some serious bioprinting open source machines. Respect.


Project description:
VITAPRINT is an open source 3D bioprinting project developed by our Symbiolab. It is a platform of open 3D bioprinting, including open hardware, methods and demo files, which serves as a basis for our collaborations with researchers from science and industry. We act as the key technology partner and help them apply the convenience of 3D biofabrication technology in their specific application and facilitate the transition of ideas into operational devices and procedures.

Hack the Electronics of Monoprice Select Mini 3D Printer

Robin Reiter wanted to develop his own custom UI for Monoprice Select Mini so he needed to reverse engineer the electronics and software. He documented the entire process in detail and made an interesting video about it. it's a must-see if you are interested in the internal working of 3d printer electronics and driver software.

DIY 3D Printable Kinetic Charger Power Bank

Here is a very useful project you can make on your 3d printer with some electronic components. It's a fully functional induction powered charger with battery power bank. It charges the battery when you move it.
All structural components are 3d printed and you will need some magnets, copper coils, battery and an electronic controller.


Main components:

  1. The Inductor consists of a 9-magnetic Halbach array and three coils.
  2. PCB contains an inductor 200mA step-up-converter, a battery charger, and a battery step-up converter 5V 2A output.
  3. The lithium-polymer battery with 2800 mAh capacity.
  4. The case consists 4 parts and is made with 3D printer.

The designer, TanyaAkinora from Ukraine named it "Elveet".

Printrbot Printrbelt Working

Printrbot Printrbelt is making some nice progress. It is a continuous conveyer belt 3d printer that can print some long objects. New videos and features are released and here is a short overview.


Here is a 6 foot long sword:





Here is Wiliam Steele from Polar3D showing how the software control is implemented on Printrbelt:
