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

Here is a video showing OCR recognition:




Project description:

At a lose for words? Can't describe an object? PiZero SmartGlass can help you with that by using image recognition tech. Make your own smart glasses easily with the Raspberry Pi Zero! Affordable and easy to build, retro-wearable 3D Virtual Stereo Digital Video glasses are around $75 along with the Pi Zero. This display uses composite video to connect the Pi Zero's video out pins and are easily customized. There are many applications for image recognition, which allows computers to translate written text into digital text. The PiGlasses can help with the field of machine vision, recognizing people and objects. Add a battery pack and your PiGlasses are ready to go!

Easy WiFi 3D Printer sharing with Microsoft IoT Core

I'm not a Microsoft fan but it looks like their IoT Core on a Raspberry Pi can get easy WiFi connectivity and network sharing for many popular 3D printers with simple app install.

Here is the video explaining the setup:




It currently supports the following printers:

• Lulzbot Taz 6
• Makergear M2
• Printrbot Play, Plus and Simple
• Prusa i3 and i3 Mk2
• Ultimaker Original and Original+
• Ultimaker 2 and 2+
• Ultimaker 2 Extended and Extended+

... but more will surely be added in the future ...

Here is the first real print of FunBot Pro with further details explained by Cliff:

How to remotly control ATX power supply modes with Raspberry Pi and OctoPrint

Standard ATX power supply unites are widely used to give electricity to 3d printers. Instructables user "mfoster" published a very useful tutorial on how to use RasPi and Octoprint to remotely control ATX power supply and enable you to put it in different power modes like standby mode.
The hack is easy to perform even by novice users, you need do use some code and conect some wires from Raspberry Pi GPIOs to ATX wiring.

Detailed instructions and the code can be found here:

DIY 3d printed water cooler block for small electronics

Instructables user Unprecedented developed a useful little 3d printable cooling block for his Raspberry Pi. It holds a copper penny on the bottom as contact to hot chip and it has plastic tubing taking in cool and taking out hot water and thus cooling the chip.

It can be used on variety of electronic parts with Raspberry Pi and other small computers being the obvious choice if you are into overclocking. Water cooling is silent and can take away large amount of excess heat. It goes without saying, if the water leaks out it will badly damage your electronics.
You could also use 3d printed peristaltic pump to push the water or just have it stream from faucet ...

It would be interesting to see how much could the design be enlarged ...
