Opendive – Low Cost DIY Open Source 3D Virtual Reality Kit for Smartphones

About 10 days ago, I wrote about solution to record and play 360 degrees panoramic videos. One of the itmen was vrAse virtual reality case for your smartphone, and allows you to enjoy immersive 3D experience. If you’d rather do your own, than buy a kit for about 100 Euros, there’s an open source project called OpenDive that does about the same thing, and allows you to play games in 3D. All you need to do is to download the 3D files, print the head-mounted glasses it with your 3D printer, and buy the lense kit (6.99 Euros) to get a complete working system. You may have to modify the design, and adapt it to your phone dimensions. And if you don’t have a 3D printer, somebody provided instructions to do your own by cutting wood or plastic sheets. You then should be able to watch 360 deg. panorama videos, and play 3D games (See current list) as shown in the …

Open Source Prosthetic Arm Controlled By Muscle Movements

Gustavo Brancante is working on a very interesting project that let you control a prosthetic arm with your muscle movement using open source technology with InMoov Hand (which can be 3D printed), Arduino Uno R3, and Olimex Electrocardiography electromiography shield (SHIELD-EKG-EMG). This is called a Myo-Electric Prosthesis. Gabriel wrote a tutorial to use his “open arm” which I’ll summarize here. On the hardware front, you’ll also need a UDP compatible Wifi Shield configured as a UDP server with a fixed IP in the same LAN as the smartphone, and 57600 bps. TouchOSC (for smartphone and Workstation) is used with the following layout for calibration and feature selection. Finally load the program below to your Arduino board: Once everything is connected together, you should be able to do that: The demo looks impressive, but this is still work in progress, and next step will be to use a four channel EMG instead of the single channel Olimex EMG shield to be able …

PengPod 700 Linux Tablet Used As a 3D Printer Touchscreen Controller

PengPod 700 & 1000 are two of the rare Linux tablets to be available on the market. Those tablets are based on AllWinner A10 SoC which can support both Android and Linux thanks to independent developers. After a successful Indiegogo campaign, where they managed to received pledges for a few hundred units of both model, people started to receive their Linux tablets earlier this year. Francesco Santini decided to purchase PengPod 700 in order to use it as an touchscreen controller for his 3D printer (Solidoodle). He modified Pronterface, a graphical user interface written in Python to control 3D printer, for the 7″ display the of PengPod tablet, and made the change available in his github account https://github.com/fsantini/Printrun-pengpod700. He uses a SAMBA share to copy G-code files (“G-code is the common name for the most widely used numerical control (NC) programming language”), and load the required file from the PengPod using the interface above. He also created the holders to …

Replicate CAPE Adds 3D Printring Capability to the Beaglebone

Beagleboard.org launched the Beaglebone Cape Design Contest back in November, several designs were submitted, and yesterday, they announced the 3 winning CAPEs who will be manufactured and sold by Circuitco Electronics: Replicape by Elias Bakken – 3D printer cape Interacto by Chris Clark – Cape with a triple axis accelerometer,a gyroscope, a magnetometer and a 640×480 30fps camera. Geiger cape by Matt Ranostay – Geiger counter cape Since today I’ve started to write about 3D printing, let’s carry on and have a closer look at the Replicape. The Replicape 3D printer cape includes: 5 stepper motors (X, Y, Z, Ext1, Ext2) 3 high power MOSFETs (PWM controlled) for 2 extruders and 1 HPB 3 medium power MOSFETs (PWM controlled) for up to 3 fans 3 analog input ports for thermistors 3 inputs for end stops (X, Y, Z) Programmable current limits on steppers motor drivers (SMD). No need to manually adjust a pot meter. Microstepping individually programmable for each SMD from …

3D Systems Cube and CubeX 3D Printers and Cubify Online Service

3D Systems was at CES 2013 to showcase their 3D printers, and their online 3D printing ecosystem called Cubify, where you can design your own model, order the object to be 3D printed, which is then shipped to your door. They have 2 printers that are available for the home market: Cube 3D printer ($1,399) Print size: 140 x 140 x 140 mm / Resolution: 200 microns CubeX 3D printer ($2,799 to $4,399) Print size: 275 mm x 265 mm x 240 mm / Resolution: 125 microns. The CubeX can support 1, 2, or 3 printer heads in order to print objects with multiple colors and/or materials. Charbax shot a video with the company, and I’ve learnt quite a few interesting things about 3D printing: It’s been around for nearly 30 years, but only used by the industry until recently. 3D printing takes a lot of time. The small spaceship shown in the picture above takes 5 hours to print, …
