The Pi-Stop is a low cost hardware module designed to allow Raspberry Pi users to take their first steps into interfacing with the real world.
Designed with the learning in mind, everyone will recognise and identify its familiar elements encouraging their use along-side their own projects.
Move past the Stop light
The Pi-Stop is designed to remove many of the common hurdles people are faced with when getting started using hardware with the Raspberry Pi. Often it is difficult to know what components to use and how to connect them, the Pi-Stop makes it simple by plugging directly onto pre-set positions on the Raspberry GPIO connector.
By plugging the Pi-Stop directly on to the Raspberry Pi GPIO header, no extra cables or wires are needed. Unlike many other add-on boards, they do not block unused GPIO pins, keeping them open for other uses. The Pi-Stop can be fitted in 4 standard locations, allowing up to four Pi-Stops to be controlled independently or combined with other hardware.
Prepare to go!
The Pi-Stop provides a simple stepping stone, between pure screen based programming and using physical hardware to interact with the real world. Components like the Pi-Stop will provide a flexible and non-restrictive way to build understanding through experimenting.
Since it is only a step away from a bag of components, it also allows the programming of hardware to be introduced, and the electronics involved can be introduced separately, if desired. Allowing the pupils to discover they can control real things, and then again to discover they can also build their own circuits and control them in exactly the same way.
Often, people are faced with a magic board which they plug in and tell it to do stuff, however it isn't always clear to them why or how it does it. By providing something which they can remove and replace with something (apparently) completely different (- wires, breadboards and LEDs) they will be able to understand the link.
By keeping the hardware very simple, it allows better understanding of what is happening, and allows space to come up with your own projects and apply the concepts with your own ideas in mind.
GO Full throttle
The documentation and guides are openly available for the Pi-Stop for educational use. There will be guides, tutorials and workshop material available all of which can be taken as is[available as PDF format] or adapted to your own needs [available in markdown format].
It is encouraged that similar materials can be submitted back for others also to share and make use of.
The materials will demonstrate the concepts, methods and provide the building blocks to explore ideas and take learning further by with creative projects, activities and games.

This easy build bike light kit has just ten parts, making it a good introduction to electronics. The kit uses two ultra bright red LEDs, which flash rapidly, providing a highly visible light. Making it ideal for use as a rear bike light.
Alternatively it can be used as a night safety product or flashing eyes.
Caution:
- This is an educational kit and should be used in conjunction with a commercially available bike light.
The Kitronik Deluxe Rear Bike Light Kit is easy to build kit and is an excellent way to learn about the very popular 555 timer IC. The kit uses four ultra bright LEDs that can be operated in two modes; constant and flashing.
A key design aim of the kit was that it should conform to all relevant British Standard measures. Both the flash rate and brightness conform to British Standards for vehicle road lighting (2005), making it ideal for use as a rear bike light. Alternatively, it can be used as a night safety product or flashing eyes.
During testing we connected the kit to 3 x AAA batteries and ran it continuously. At 80 hours of continuous use the LEDs were still lit at full brightness. After 107 hours, although still lit, the brightness had dropped below the level at which you would want to use them. So, we estimate that with brand new batteries you could comfortably run the light for 2 hours of daily commuting for at least an entire month with the LEDs still at full brightness.
Features:
- An easy to build rear bike light project that conforms to British Standards for vehicle road lighting (2005) for both brightness and flash rate.
- Learn about the very popular 555 timer IC.
- The kit features 4 x bright LEDs.
- It has two operating modes; continuous and flashing.
- Its compact design makes it the ideal choice for designing custom enclosures.
