I love hearing about how people are using the Pi-Stop to discover and learn, many thanks for sending me your stories of what you have got up to with them.

Remember you can now buy them directly from 4Tronix and also CPC Farnell.

I recently I was asked about using them with Python, well it was always my intention to produce a full Python workshop with the Pi-Stops, but I hadn’t quite got around to it.  Although there is the Python Pirate workshop, which I ran back on 29th Nov 2014, it used a rather specific python module for to make the Pi-Stop function as a lighthouse signal (lighthouse.py).

I decided it was about time I created a more general python module for the Pi-Stop.  So I have!

Check out the Pi-Stop Github for details and let me know how you get on with it (and feel free to add/request changes).  I shall add additional comments to the file and some additional tips on how to use it, but it should make a good starting point.

Get the module here: pistop.py

Note: It will work with the Raspberry Pi 2 (as well as Model+ versions – in all 6 locations).  But you will need the latest RPi.GPIO (version 0.5.11) for all the pins to work correctly.

Using the new Raspberry Pi 2 (or Model A+/B+) you can run up to 6 Pi-Stops independently, directly off the GPIO header.

When I get chance I’ll start writing some workshops which make use of it, as well as one which explains how it is constructed.

Enjoy!

*Yes, F is Fantastic, don’t let anyone tell you otherwise.  I would probably say PRTM – Please Read The Manual, but that isn’t quite as well known.

5V DC-DC Switch Mode Power Supply, and RGB-LED Kit User Manuals

As always, the user manual is the last item to be completed (and often never is entirely in engineering)!

I am proud to announce the release of my latest kit, a 5 way RGB-LED test module.

RGB LED Module connected up to Rev1 Raspberry Pi ready to go!

A big thank you to those who have brought the PSU Kit, your kind support meant I was able to continue developing and create this kit.

Adafruit’s Pi T-Cobbler

I recently received the Pi T-Cobbler, a very convenient way to interface with the Raspberry Pi.  It takes the GPIO header and breaks it nicely out into two neatly labelled rows and plugs directly into a breadboard.

Introducing Raspberry Pi Hobby Project Kits

PhotobucketPhotobucket

Aim of the kits:

The kits are designed with the concept of “Learning Through Practical Thinking” at its core.
The idea is that learning is much more effective when combined with physical activity and discovery, rather than straightforward reading and repetition of cold facts.  The kits will be developed which encourage development of new skills and to apply them as part of practical projects.
