3D printable low cost foldable Bluetooth head mounted display

Tony created this very cheap piece of DIY wearable eyespace technology. It is foldable wearable display that connects via Bluetooth with your Android or computer.

Everything displayed on this head mounted display is controlled by either an Android phone or a Bluetooth connection to a desktop. Using relatively simple display and simple Arduino means it is limited to text and very simple graphics, but this is more than enough for some useful applications like reading SMS messages and checking email.

From project description:

The OLED display is a small .96" display controlled by an arduino nano board. The display receives text and commands from a HC-05 serial Bluetooth module connected to the arduino. There is also a small speaker and RGB LED connected to the board. The OLED display, RGB LED, and speaker are all controllable over Bluetooth. 

The device is powered by an Adafruit powerboost module connected to a small 0.7Wh lipo battery. The optics are a small mirrored right angle prism and a magnifying lense. The frame and casing is all 3D printed with ABS using a Solidoodle 2 pro printer. 

The Arduino communicates with the OLED display using i2c (inter-integrated circuit). The RGB LED and the speaker use the arduino's digital output pins. The display is controlled over blue tooth using a application running on an Android phone or Linux terminal. The glasses are very portable and foldable.

Total cost ~$60.

Kudos Tony!

RepRap Phone Host 3d printing app is released into Windows mobile phone ecosystem

Bananna3d is 3D printing technologies company in Pretoria, South Africa run by Gerhard de Clercq and Pieter Scholz. They successfully developed Windows mobile phone 3d printing application.

From app description:

RepRap Phone Host is a Windows Phone 8 application that allows you to process and then ultimately 3D print STL format 3D models on your "RepRap" type 3D printer running "Repetier" firmware and in possession of a Bluetooth serial bridge.

It includes a STL and GCode render as well as our in-house developed "Bananna Chopper" slicing engine. As far as we know this is the first app the allows a model to be sliced on a smartphone.

To get the app up and running all you need is to add a Bluetooth serial bridge to your 3D printer (there is a tutorial on the RepRap site), pair with it in the Bluetooth menu and then just select it from the drop down menu inside the app and connect to it.

NOTE: This app requires a "RepRap" type printer with "Repetier" firmware and a Bluetooth serial bridge. As long as you have a "RepRap" type 3D printer you should be able to find information on how to load "Repetier" firmware on it as well as how to add a Bluetooth serial bridge.

This app has the ability to open .stl and .gcode files from email etc. as well as the ability to upload all internal STL and GCode files to your SkyDrive folders.

I have a feeling that Microsoft will react to this ... maybe buy it (them) ...

If you want it on your Windows phone here is the MS store link:

GCode Simulator & Print software - controlling 3d printing on PC, Android or via Bluetooth

GCode Simulator is software package of several programs / apps that run on PC or Android device enabeling you to simulate G-Code 3d printing on your PC and on Android and giving you full control of compatible 3d printer in paid (1,99 €) version.
This is very useful since there is plenty of very affordable low cost Androide devices such as tablets that can provide you with powerful touch screen 3d printer controller.

GCode Simulator also supports wireless printing over Bluetooth. GCode Simulator & Printer can connect to Bluetooth enabled 3D printers. Any RepRap 3d printer based on RAMPS can easily be extended to support Bluetooth by connecting a JY-MCU Bluetooth serial  module.

Video of GCode simulator on PC making a 3d printing simulation:

Ultimaker printing via Bluetooth and glass printbed customization

Petleh82 improved his Ultimaker. He added cheap Bluetooth module to enable wireless printing. He also stopped using blue tape on printbed and replaced it it with glass. To get PLA to stick to the glass print surface he coated it in mixture of wood glue and water. He successfully printed with nylon on glaass since it has problems sticking and warping on blue tape. Nice projects Petleh!





Check out previous post with a video on his one year with the 3d printer. He really shows how printers are useful and fun in everyday life:
