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.

Check out Robin's YouTube channel:

All the code is available on the GitHub:

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:

Prusa New Water Soluble Supports

Slic3r Prusa Edition in the latest version 1.36.2 comes with improved printing with water soluble supports. On Prusa i3 MK2 MultiMaterial you now have three ways to print with support. Basic supports from the same material as on regular MK2/MK2S, water soluble supports everywhere and water soluble only on the interface layers.

Here is the video presentation:

With this features, Prusa is getting more powerful and competitive even when compared with much more expensive machines.

Future Fabrication at MIT's Center for Bits and Atoms

If you are technology and science nerd you have to see this tour of MIT's Center for Bits and Atoms.

This is the place where some amazing tech is being developed for real world application purposes.
You will see some advanced gene editing, micron level 3d imaging, and manipulation, micron level laser cutters, molecular assemblers and nano machines.  

Part 1

Part 2

Some very very cool stuff kids!!!

First look at Cloud Based Fusion 360

Many of you use Fusion 360 as main design application. Adafruit team shows us the first view at browser based Fusion 360 system. Personally, I'm more fan of the open source software and I don't like to depend on a big corporation.
