Raspberry Pi 7” Touchscreen Display
The 7” Touchscreen Monitor for Raspberry Pi gives users the ability to create all-in-one, integrated projects such as tablets, infotainment systems and embedded projects. The 800 x 480 display connects via an adapter board which handles power and signal conversion. Only two connections to the Pi are required; power from the Pi’s GPIO port and a ribbon cable that connects to the DSI port present on all Raspberry Pi’s. Touchscreen drivers with support for 10-finger touch and an on-screen keyboard will be integrated into the latest Raspbian OS for full functionality without the need for a physical keyboard or mouse.
Technical Specification:
* 7” Touchscreen Display
* Screen Dimensions: 194mm x 110mm x 20mm (including standoffs)
* Viewable screen size: 155mm x 86mm
* Screen Resolution 800 x 480 pixels
* 10 finger capacitive touch
* Connects to the Raspberry Pi board using a ribbon cable connected to the DSI port
* Adapter board is used to power the display and convert the parallel signals from the display to the serial (DSI) port on the Raspberry Pi
* Will require the latest version of Raspbian OS to operate correctly
Features and Benefits:
* Turn your Raspberry Pi into a touch screen tablet, infotainment system, or standalone device.
* Truly Interactive – the latest software drivers will support a virtual ‘on screen’ keyboard, so there is no need to plug in a keyboard and mouse.
* Make your own ‘Internet of Things’ (IoT) devices including a visual display. Simply connect your Raspberry Pi, develop a Python script to interact with the display, and you’re ready to create your own home automation devices with touch screen capability.
* A range of educational software and programs available on the Raspberry Pi will be touch enabled, making learning and programming easier on the Raspberry Pi.
Kit Contents:
* 7” Touchscreen Display
* Adapter Board
* DSI Ribbon cable
* 4 x stand-offs and screws (used to mount the adapter board and Raspberry Pi board to the back of the display
* 4 x jumper wires (used to connect the power from the Adapter Board and the GPIO pins on the Pi so the 2Amp power is shared across both units)

Nixie Clock
“All-In-One” Arduino Nixie Clock
Detailed Description
The Arduino “All-In-One” Nixie Clock kit drives 6 IN-14 Nixie Tubes in a traditional “6 in a row” set up. It’s packed full of features, and at the end of the simple build you will have a beautiful IN-14 Nixie Clock. The board is small (150mm x 50mm), and is an easy to build and is a tried and tested design, with many hundreds of units sold.
This kit is based on an Arduino (Atmel ATMega) micro controller. You don’t need to own an Arduino to use this kit! It is self contained and runs without an external Arduino board.
The controller comes pre-programmed. You you can download, modify and upload the open source code if you wish.
This kit is ideal if you want to make an unusual or eye catching clock in a custom case.
Even better: The code is open source, with regular updates and new features.
WiFi Time Provider
If you already have a Clock with the battery-backed RTC (Real Time Clock) module, you can easily upgrade it to use the WiFi time provider module.
This gives you all the advantages of the WiFi kit. You need to have firmware V44 or later to use this.
You set the WiFi provider once once, and it never needs setting again, ever! It also allows you to configure the clock using a browser.
