After putting jessie raspbian onto the card and set up the configs i downloaded the lightshowpi software before wiring up the lights to a relay board. I didnt run into any problems as the lightshowpi site is well written. The only problem i did notice was my relay board being noisy but im hoping by getting a solid state relay board this will solve it.
Here is a link to the youtube video i made.

I decided a while back that after doing my Christmas tree last year in NeoPixel lights http://www.youtube.com/watch?v=uoGk0M8YdMA and using Penguin Tutors excellent DJ lights program https://github.com/penguintutor/neopixel-gui that this year I wanted a Cheerlight item (cheerlights.com) like I had run on the Unicorn Hat by ForToffee https://github.com/ForToffee/UnicornHAT Cheerlights is an internet of things where people use twitter and the hashtag #cheerlights and a colour and all items running cheerlights around the world will change colour to the current tweeted colour.
So the hunt was on for something I could use and low and behold I came across this laser cut house that had a battery pack running some plain leds inside. Once it arrived it was time to strip out the lights and add 13 neopixels inside on a long strip, but to be able to get inside i needed to use a craft knife to carefully remove the roofs and one building.
Once in place I soldered the pixels to a MyPiFi neopixel controller board and attached to one of my pi's http://smstextblog.blogspot.com/2015/03/afirstly-thank-you-for-purchasing-this.html . I then glued everything back together and then followed Tonys great NeoPixel how to guide off of adafruit https://learn.adafruit.com/neopixels-on-raspberry-pi/overview Once all the software was in place I ran the first test and all seemed fine it worked. However when I tried to run the Cheerlight code from David Bradway https://github.com/davidbradway/cheerlights I just couldnt get it to work. I asked about and was told two different things to try so tried both at the same time, the first was to use an old pi with 26 pin header and second was to use Raspbian Wheezy and not Jessie which I tried and bingo, it worked I couldnt believe it.
I have since glued the Pi and the display to some thin mdf word to keep it all together and stop the wires being pulled and this is the finished result.
There is still some coding bits to fiddle around with but apart from that this is now ready for the christmas festivities and perhaps after christmas i could remove the christmasy figures off the front and just have this as an everyday cheerlight display for my desk.
Thank you for reading and please share.

Well its why everyone is moving over to ingress, no more travelling hundreds of miles to get a smiley, getting ivy rash from searching through ivy for a micro or searching through rubbish in a layby for a watersoaked logbook that's seen better days.
I tried munzees in the summer and was bored rather quickly, scanning barcodes and quite often some that were rather weathered and wouldn't scan I needed something better, remembering that a friend had shown me an app last year but was only available for android at the time (now on iPhone too) I decided to give this new game ago.
Its called ingress, its about battling blue team (the best) versus greens (the enemy), you pick a side and that becomes your fraction. The idea is to take over portals which are places of interest and of which scores you points and linking them to other portals which can be captured and recaptured many times a day in busy spots. Portals are normally submitted to show places a visitor might not go, a work of art, sculpture, area of interest or historic value. I for one have discovered new things locally as well as visited things I've forgotten and so far other players have been great with advice and support and best of all its free.
So it looks like I've discovered a new way to pass my time and enjoy what's around me without spending loads on petrol travelling to my nearest cache. Take a look and let me know what you think.

While I recommend a 5v 4amp power supply from CPC.co.UK you can use an outdoor lights 5v 4amp supply.
Here is what you should have to start with:
1x gpio header
1x PCB board with chip already on board
3x terminal screws
Using any method you have to hold board in place start by soldering the gpio header being careful not to melt the chip.
When finished the board should look like this.

I got a Ravpower filehub through this week, an RP WD02 model and thought I would run it through its paces.
Now normally when I attend Raspberry Jams I have to take an extension lead and battle for a power socket or take an external battery pack, then so I can connect to the pi either a big laptop or my phone plus the tp link access point plus lead to power it off the external battery.
Not with this, its a six in one device. It has a wireless router that you can use as an access point or link to your mobile or plug into a hotel internet socket for internet. You also have a micro sd card slot that can be used as a card reader or a nas file server, I'm guessing it can only take up to 64gb like what I'm using but couldn't find details anywhere so enough for 15 good quality films, over 10k 3 minute music tracks or just use it for your backup images.
Next was the battery which from flat took me 4 hours to charge with the official Raspberry Pi power adapter and best of all, with one of my add on boards flashing leds last for over the length of an average pi jam to an incredible 12 hours, 14 hours with my seven segment clock display making this more than brilliant for travelling as now I don't need all these extra things just the pi, this with its included lead will also fits from the hub to the pi power socket, wifi dongle and my smartphone (plus the add on board I'm showing) simples.
So do I recommend it? well I love the tp link travel router/access point, but this was so much easier in my opinion to set up and price wise considering how many items are built into this is good value, so yes, now it means I can attend jams again without having to lunge around lots of boxes of kit.
