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".

3D Printing Parts for Cryptocurrency Mining Rig

Cryptocurrency mining is booming again with Ethereum currently being one of the most mined coins. In many countries graphics cards (GPUs) used for the process are hard to find or are much more expensive. For mining purposes, several cards are mounted on a single motherboard with a riser connector and attached to an open external rig for more space to get better cooling air flow.
Most mining rigs are self-built by the operators who always want to get the best price to quality ratio.

Here are a few very practical 3D printable DIY modules you can make yourself and use in your setup.


Here is a somewhat typical mining rig but all the connections of metal profiles and structural elements (red and black plastic) were 3d printed:

If you don't want to keep your GPUs on a riser connected to a rigid frame to get more space or flexible arrangements for better cooling, you can use DIY 3d printed card holders.

Here is a different type of vertical GPU holder with focused ventilation opening:

Using 3d printing to build your hashing beast is a great way to ensure spare and replacement parts and it gives you much more customization options. You can also get various type of fan holders, air flow focusers, PC component holders, and many other components.

ZeroBot is a 3D printable FPV robot based on Raspberry Pi Zero

ZeroBot is a cool little 3d printable robot that is cheap and easy to make. Great for educational robotic projects. You can control it via the smartphone interface and all the software is available as SD card image. I'm making this!!!




Project description:

ZeroBot is a Raspberry Pi Zero W based robot. It can be controlled using any computer or smartphone via a web browser. The integrated camera module makes for a low latency video stream. In addition, the Raspberry Pi acts as a Wifi access point, so no router is required. The parts for the hull as well as the wheels can easily be printed on any regular 3D printer. 

Some of the key features are:

• Compact CAD design with 3D printed components

• Analog control via a joystick (and multitouch)

• Simple battery solution using only a standard power bank

• Low latency streaming (~0.3s)

• Easy and cheap to build using widely available components

3D Printable Parametric Slew Bearings

Christoph Laimer published  another very useful project. He developed a fully 3D printable and working parametric slew bearings. Since they are developed to be sturdy they can be used in many different project where a simpler 3D printed ball bearing would fail.

Since the design is parametric, you can adapt it to fit your needs. One version even has conical bearings.

Project description:

Ball-bearings are very popular for 3d-printing. However they often fail for real applications. Using Fusion 360 I've created a parametric design of a "Crossed Roller Slew Bearing". The result is a pretty accurate and robust bearing. The bearing including the rollers is 3d-printed in separate parts. There are a few screws needed to clamp the two halves of the inner race together.

Here is the full video:
