For a £80 I managed to get a new HikVision DS-2CD2032-I camera which supports a crazy 2048 x 1536 @ 20 FPS!
The camera can mount NFS as well as SMB/CIFS file shares, although a few people have had issues. And here is where my issues started (I did get it working). The camera management page has a section for NAS, and you can select you server, share, CIFS as well as credentials. Read more... (568 words, 11 images, estimated 2:16 mins reading time)
We have been playing quite a bit with the new Raspberry Pi, a previous article covered video recording using a USB Webcam and a neat little piece of software called Motion. If you haven’t seen that yet, have a look at http://sjj.azurewebsites.net/?p=701. Read more... (716 words, 2 images, estimated 2:52 mins reading time)
The concept of the Internet of Things revolves around connecting everyday (household) objects to the internet. The important thing to consider is that all this data is being generated, but is only useful if something is being done with it. The Microsoft Azure Service bus allows you to process queues of such data and make it more useful. Read more... (884 words, 5 images, estimated 3:32 mins reading time)
I just managed to get my hands on the Raspberry Pi (Model B+), so now i have a spare Model B, so what to build? I also have a USB Webcam (Trust Spotlight Webcam), so a DIY CCTV sounds like a great start. Turns out there’s several different applications to using the Rpi for home automation and other similar tasks. One of the most exciting projects is to use the camera for motion detection record video/images when motion is triggered. This blog posts provides a step by step guide on how I set up my PI and cameras, well as a live webcam server, and couple of other interesting things. Read more...

I have a great little RTC from Love Electronics, it uses the DS3231 chip which is similar to the DS1307 (as shown in this article http://www.l8ter.com/?p=417)
Since I am starting out using mbed (https://mbed.org) it is probably a good example to see if the DS3231 works with the LPC1768. I started by using the DS1307 library as a guide, but then noticed that there are a few differences. (Note there is an mbed DS3231 library you can import) Read more...

Ever wondered how the pro’s physically manage to make a module? Well ok, you can get a fancy pick and place machine or send off for someone to assemble your module, but you can do it by hand. It is not as hard as expected. Read more... (1258 words, 7 images, estimated 5:02 mins reading time)
We met up last night to have a look at a .NET Gadgeteer module, picking a nice easy module to look at to begin with for: http://www.meetup.com/GadgeteerSouthCoast/. Despite being called the GHI PIR Sensor it is found in the toolbox as a “Motion Sensor”
Here is the view from the top of the module: Read more... (1060 words, 7 images, estimated 4:14 mins reading time)
When you drag a module from the toolbox onto the designer it references the correct DLL’s and adds import statements to the program.cs.

There is a case, where you can get a blue screen of death (BSOD) where your computer just dies/reboots, usually during a NetMF or .NET Gadgeteer deploy and especially if you hit the reset button (on the device) or attempt to pull out the USB cable.

I swapped the ColourSense (http://gadgeteering.net/module/ghi-colorsense) module for a triple slider (http://gadgeteering.net/module/soldermonkey-triple-slider-module).
