Yet another home automation project

Posted on June 25, 2015 by R-B One comment

Saiyam’s bedroom automation box is a standalone and multi-feature home automation project using Arduino with a set of six sensors which can be used in combination with each other to control home appliances like fans, coolers, lightening systems, etc. You just need to connect your appliance to the power socket present on the box with a plug that makes connecting anything easily. The device asks you to set a mode which means, which sensor you want to use for controlling the output (see all the modes below). Further it asks you to threshold for the sensor you have chosen (like

Arduino enclosure with a human machine interface

Posted on June 23, 2015 by R-B Leave a comment

Mircea Daneliuc from Whitehorse, Canada has tipped us off about his Arduino Enclosure with a human machine interface (HMI) consisting of an LCD and six push switches. The enclosure is a 140mm X 90mm X 63mm (5.5′ ‘x 3.5” X 2.5”) industrial grade ABS plastic with ventilation and screw terminal slots. The HMI takes only 3 analog pins of Arduino. The keypad is a simple 6 button matrix keypad. It comes with a 2.54 mm pitch female Dupont connector. It has UP, DOWN, LEFT, RIGHT, ENTER and MENU buttons. These can help you navigate and change values for any menu you

Full featured open source industrial camera

Posted on June 15, 2015 by R-B One comment

Apodiant’s entry for the 2015 Hackaday Prize is a full features open source industrial camera with Ethernet, USB, and serial outputs, along with an ARM processor for image processing. The major parts are as follows. CPU: i.mx6SL (With GPU, no e-paper interface). I have decided on this due to the ease of use. The Linux distribution is mature and has many active developers. The GPU can also be programmed with openGL. OpenCV will handle CPU image processing. Image Sensor: I have chosen the MT9M021 from aptina because I have the most experience with this imager and the price is suitable for this

PiClock: A RPi-based clock and Weather display

Posted on June 13, 2015 by R-B One comment

Hackaday user Kevin Uhlir‘s PiClock is a Raspberry Pi-based fancy clock with weather forecasting and RADAR map display features. The clock retrieves the Weather data from Weather Underground using their API (http://www.wunderground.com/weather/api/ ) and the maps are from Google Maps API. An HDMI monitor is interfaced to RPi for displaying the information.

Continuous liquid interface production enables faster 3D printing

Posted on June 13, 2015 by R-B One comment

The most common technique of 3D printing is stepwise horizontal layer-by-layer approach to fabricate 3D objects, which is very time consuming and is the same process used by most commercial 3D printers in the market. A team of researches led by Joseph DeSimone, a chemist at University of North Carolina and CEO of Carbon3D, invented Continuous Liquid Interface Production (CLIP) technique that can print 3D objetcs from liquid resin at game-changing speeds. Check this cool video of printing a 3D Eiffel Tower model using this approach. Traditional 3D printing requires a number of mechanical steps, repeated over and over again in a layer-by-layer
