My family and I (wife plus two young children) are away travelling the South Island of New Zealand for our summer holiday.  At least one of the places we are staying hasn't upgraded their TV to go digital, the owners usually take their Sky decoder with them.  With our car already loaded to the gunwales with a double buggy, two kids car seats, buckets and spades for the beach, fishing rods, a small selection of christmas toys, and enough clothes to cover four seasons, packing anything e ...
Before you watch this project... see my others: - The "Scary Door" - "Project Goldie"     C http://twitter.com/Cabe_Atwell   New Year’s Eve (NYE) is always fun, especially when something fun happens at the zero time. Launching fireworks seems to be the default response to the calendar change. Having it do off exactly as the year comes to a close is key. The person that is often required to light those wicks loses out to enjoying that moment. (They have to be on the ...
Hi all,   The latest update on my project; using the raspberryPi as a controller for a hydrogen fuel cell with the intent on powering a remote controlled plane.   Hope you find the video interesting and inspiring, if so please click LIKE!   Regards,   Simon   ...

Sleepy Pi Overview

Posted by shabaz Top Member Dec 14, 2013
Introduction The Sleepy Pi is a board produced not a million miles from my home town, and it is designed to extend the Raspberry Pi (RPI) capabilities. After having examined it, the conclusion is that the board is fantastic with a rich set of functionality and extremely well-designed, and it will provide tremendous value for projects with the types of requirements listed below. This board should interest people with any of these requirements: 1.    The ability to run the RPI f ...
Introduction This was a fun project to try to make some flashing lights. Of course, it needed to be a bit more complex than that so a Raspberry Pi was used for Internet connectivity, and some analog circuitry was used to generate multiple PWM outputs to drive strings of lamps. Everything can be dimmed or particular patterns selected from any web browser. For a holiday look, the lamps were enclosed in star-shaped laser-cut acrylic. All the steps are detailed here if you wish to build something s ...
As a keen photographer, I was intrigued by what the Point and Shoot Camera could deliver. The bundle is created using the Raspberry Pi, PiFace Control and Display and Pi Camera, all packaged up in some rather smart cases.   The set up and execution of the timelapse is brilliantly simple, with the hardest part of the whole project being deciding what the subject should be. One thing I will say is choose a place that will be undisturbed by movement or light – discovering my sunrise tim ...

Hydrogen Fuel Cells!

Posted by howroyd Dec 2, 2013
Hydrogen fuel cells (in particular PEMFCs) are an exciting technology which has been around for a while now. Unfortunately, they haven't really take off (excuse the pun) due to their high cost, poor lifetime and slow transient performance.   1. So why are people still interested?   Well, firstly you have the good old "clean & green" argument. In operation, the take in oxygen (from the air) and hydrogen (the fuel), and give out heat, water and electricity. No carbon dioxide, monox ...
