> **Source:** Core Electronics is an Australian maker-electronics retailer and manufacturer based in Newcastle, NSW, run by a team of makers and educators. We design and manufacture our own product lines (PiicoDev, CE originals) and are official retailers for iconic maker and industrial brands including Raspberry Pi, Arduino, Adafruit, SparkFun and DFRobot. Orders ship Australia-wide from our Newcastle warehouse. Prices are in AUD and include GST. Pricing, stock and dispatch on this page are generated from the store's live catalog.

Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/CE05633:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description Designed with the learning in mind, everyone will recognise and identify its familiar elements encouraging their use along-side their own projects. See [this independent review](https://teachprimarycomputing.wordpress.com/2015/03/30/the-pistop/) **Note: This only comes with one individual traffic light.** ### 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. ### Pi-Stop Documentation The following material is available (in both PDF and markdown format): - [Discover: The Pi-Stop](https://github.com/PiHw/Pi-Stop/blob/master/markdown_source/markdown/Discover-PiStop.md): Learn what the Pi-Stop is and how to use it. - [Setup: Scratch GPIO](https://github.com/PiHw/Pi-Stop/blob/master/markdown_source/markdown/Setup-ScratchGPIO.md): Get up and running with Scratch GPIO ready to use with the Pi-Stop.([pdf](https://core-electronics.com.au/attachments/localcontent/WS-Setup-ScratchGPIO_15942034853.pdf)) - [Explore and Challenge Scratch GPIO: Pi-Stop First Steps](https://github.com/PiHw/Pi-Stop/blob/master/markdown_source/ExploreScratchGPIO-PiStopFirstSteps.md): If you've not used Scratch before, this will provide a quick introduction to building your first Scratch GPIO program.
