Ten essential Raspberry Pi projects Ten projects for the Raspberry Pi that range from educational to fun via highly useful. This is by no means an attempt at a definitive list and the term essential is somewhat subjective, but if you're stuck for something new to do with your Raspberry Pi there may be some ideas here! 1. Have fun with LEDs LED light chaser project (© SK Pang Electronics Ltd) Bringing VR to the Web with Google Cardboard and Three.js Virtual reality is coming. You know that as a developer – you want in. The Oculus Rift, Gear VR, HTC Vive and more are making waves, yet many developers don’t realise just how much potential there is in the simplest of them all – Google Cardboard. I’ve been doing a series of IoT related articles here at SitePoint, exploring connecting web APIs to almost anything. So far I’ve covered web APIs and the Unity game engine, the Jawbone Up API and Node.js and displaying web API data on an Arduino LCD via Node.js.
Smartenit adds the sweetness of Linux Home Automation to Raspberry Pi making it HomAidPi à la mode HomAidPi-Press PRLog (Press Release) - Jul. 26, 2012 - San Juan Capistrano, CA Smartenit, Inc. There is nothing as tasty as homemade raspberry pie in the summer, and the ice cream on top makes it even more delicious, especially when it’s free. Smartenit®, a home and building automation solutions provider, has added the popular Raspberry Pi® board to their repertoire of Linux platforms that run its XML-socket based automation package. The firmware enables the RPi to become a fully-featured and sophisticated automation gateway that manages large home/building automation networks based on ZigBee®, INSTEON® and X10® protocols. “HomAidPi” in a Raspbian equipped RPi plus one of several USB automation interfaces available from Smartenit and other suppliers, provide access to a large ecosystem of automation devices that include lighting, HVAC, irrigation, appliance control, energy management, water management to name a few.
Surface data sensors during drilling - By analyzing cuttings, drilling mud, and drilling parameters for hydrocarbon-associated phenomena, we can develop a great deal of information and understanding concerning the physical properties of a well from the surface to final depth. A critical function in data analysis is familiarity with the different sensors used for gathering surface data. The primary types of surface data sensors are discussed in this page.
Hack your own radio transmitter Posted on 3 Apr 2013 at 12:02 Paul Ockenden gives a primer on how to use a short-distance radio to beam data between devices My last little exploration of the RF spectrum was actually only part one of a two-parter that continues here. We’ve done the theory test; now it’s time to get our hands dirty with the more practical side of things. I’ll be showing you how to hack together a simple and cheap system for short-range radio data communication. How to Set Up SSL on IIS 7 Introduction The steps for configuring Secure Sockets Layer (SSL) for a site are the same in IIS 7 and above and IIS 6.0, and include the following: Get an appropriate certificate. Create an HTTPS binding on a site. Test by making a request to the site.
Open Home Automation Looking for a cheap IEEE 802.15.4 transceiver? I was already thinking about hacking the Philips Hue lighting adapter. But there is a cheap (<10 Euro) adapter available from Microchip. Note, that this implements pure IEEE802.15.4, not the whole ZigBee protocol stack. If you want to use it for ZigBee, you will need an additional powerful microcontroller (at least 128kB Flash and 4 kB RAM).
my braindump: Removing Raspberry Pi partitions from SD card under Windows 7 on with the fun ... as I said the data from Google calendar events come back from the API as a Python list, and if there are no events to display the code from returns an error. After a fair bit of searching and testing I found a simple test to find out if there is any data there: eventTest = events.get( 'items', None) so that's simple to test before running the bit that causes the error.
