Whilst stocks last there is an offer for all four MyPiFi boards on eBay £18 delivered (uk) or plus delivery (row) they are for the LED board, LCD add on module, 10 LED board and the I/O port expander board giving your Pi more inputs and outputs.
Available on eBay for a short time when they have gone they won't be re added
Never really got that far with a 32x32 display, ok I followed Raspberrypi-spy s guide and got it to display things but wanted to try more out like Peter Onions excellent RGB demo.
So after running into difficulties compiling the c code from peteronion.org.uk/PiProgs I emailed Peter, I needed to add -lm to the end of the line and bingo worked straight away. The demos that Peter has included include Tetris, Clock, game of life, Squares and kaleidoscope and shows how a simple screen can be made to do literally anything.
I've since seen pictures over the tinternet showing the same displays being used to show pictures and framed in a frame too.
Many ideas and possibilities for this great rgb device.
MyPiFi add on boards for Raspberry Pi http://pages.ebay.com/link/?nav=item.view&alt=web&id=181629776059
A long time ago I reviewed the energenie Pi kit consisting of a Pi add on board and two sockets. Since then I have used ssh to ssh to a Pi to run Amy Mathers Python script that she infamously wrote on work experience at Raspberry Pi Towers.
Now since then I decided to see what else I can do and found a great tutorial http://www.penguintutor.com/raspberrypi/pi-power and followed it. Using a model a with wifi I have a device that should it go down I can ssh into to restart, but more importantly I can use a web browser and enter the Pi IP address and get buttons to choose what I want.
The problem now is I want more and more of these sockets as the Pi is about to automate my house.
Whilst I've never had a problem with the range, I've added 135mm of wire to the antenna which has a nice little hole to solder some wire to, this will boost the range so I should have no problems hitting anywhere around the house.
Feel free to have a go yourself, a starter kit of one energenie add on board and two sockets starts at £19.99 with additional sockets £10 each or 3 for £20 and the big pack of 4 for £25
Now I'm off to make that tea as the kettle has just finished boiling.
I forgot how many extra boards I have paid for over my last few kickstarters, so after taking stock of what I had left and needing to make space for future projects I have decided to place up a four board offer on eBay for £18 including free uk postage and packing, saving buyers £10 off the usual price.
The boards included are:
The LED board, three LEDs and a button with assembly instructions and demo code on MyPiFi.net
The second board is the LCD add on module so you can add any hd44780 compatable board eg 16x2 or 20x4 LCD to your project and again comes with assembly guide and demo code to get you started, all you need is to buy a LCD screen to plug into it.
The third board is the 10 LED board, this can be used with the Raspberry Pi or any other GPIO board like arduino with jumper wires or with a port expander board like my forth board.
Then we have the forth board, this is an in/out port expander for controlling things like LEDs via the SCL and SDA pins freeing up many of the other GPIO pins so you can add more to your projects and like with all my add on boards comes with extended GPIO headers so you can still use the GPIO pins.
All common kit form starting at £6 each or all four for £18 on eBay. http://pages.ebay.com/link/?nav=item.view&alt=web&id=181629776059
Here are just a few people showing theirs on Twitter.
So what you waiting for? Great way to learn on the Raspberry Pi with room to keep building and building as you get better and more confident with the Pi.
I also do discounts to code clubs and Pi shops if you are ordering in bulk too, just contact me for further details.
The huge list of projects that can be achieved with this add on board include:
Traffic Light Sequence
RSS News Ticker
Model Railway Points Controller
Internet Radio Alarm Clock
Bedroom Burglar Alarm
So far I have found averagemanvspi has done the Internet radio, but piandbash do have a forum on their site should you fall into any problems and Rob Boyle the creator is also very helpful should you approach him direct.
There will be some tutorials soon to get you going with all the functions, although the demo code is a great starter to get the feel.
While it seems to be expensive at £23 from modmypi https://www.modmypi.com/raspberry-pi-expansion-boards/pibash-add-on-board you need to remember you have several boards plugged into this one board, leds, lcd, I/o expander, buttons and temperature module so five boards into one and that's just a quick look over it, I expect with the functions combined you could claim it to have more module boards included.
So value for money, I have experience of putting out add on boards with my own MyPiFi brand and can say price wise it's cheap, no huge mark ups and you certainly couldn't get the bits yourself any cheaper as the major cost factor is the PCB.
Perhaps this is what the gertboard should have been?
