  • Diffused 5mm Fast Flashing RGB LED - Pack of 2 (LEDFKSHF)
    These are very interesting 5mm diffused RGB LEDs - instead of having 4 pins to control 3 LEDs, they have only two leads - power and ground. When powered, the LEDs perform a flashing effect with all the colours. See the video below for the timing and look. There is no way to change the 'program' or rate as it's burned into a little chip that is inside the LED itself. We also have a version that's a 'slow fading' RGB colour cycle.

    They're fairly bright LEDs, we guess its something around 1000 mcd total. They do diffuse nicely so you can the color changing from any angle. The forward voltage of the whole LED is about 3.4VDC but you can drive them from a lithium coin cell like a CR2032 and they'll just be a little dimmer. We don't have a datasheet showing the current draw over different voltages and colors but at the 'rated' 3.4V its approx 20mA and at 3.0V its approx 10mA.

    Comes in a pack of 2 LEDs. Although the LEDs are all the same shape and have the same basic program, due to manufacturing variables they will not sync together - they'll slowly drift in and out of sync

    Bit:Bot Fully Integrated Robot for the BBC Micro:Bit

    NB. BBC Micro:Bit is NOT included unless specifically selected with the checkbox

    This (almost) ready-assembled robot requires no soldering, no wires and nothing more than a screwdriver to complete it.

    The Bit:Bot fully engages children and adults alike, allowing you to explore and code the BBC Micro:Bit using any of the languages available (not all features are supported in all languages)

    Check out these features:
    • 2 micro-metal gear motors. Both fully controllable in software, for both speed (0 to 100%) and direction (forward or reverse)
    • Wheels with rubber tyres for maximum grip
    • Really smooth metal ball front caster
    • 12 mini neopixels in 2 sets of 6 along the arms either side. Select any colour for any pixel, produce stunning lighting effects as your Bit:Bot moves around
    • 2 digital line following sensors. Code your own line-following robots and race them to see whose code produces the fastest lap time!
    • 2 analog light sensors (front left and front right) so your Bit:Bot can be programmed to follow a light source such as a torch, or you could code it to go and hide in the darkest place it can find
    • Buzzer, so you can make beeping sounds whenever you want
    • Powered from integrated 3xAA battery holder with on/off switch and blue indicator LED
    • Easily plug your BBC micro:bit in and out using the edge connector
    • Extension port for addition neopixels (such as McRoboFace)
    • Expansion connections at the front for additional sensors (Ultrasonic rangefinder available now, more in development)
    Optionally, you can add an Ultrasonic Distance Sensor (rangefinder) module. The sensor can be either soldered to the module, or connected via a socket. No soldering is required for either version. The socketed version makes it easier to connect a micro-USB lead to the Micro:Bit, but the soldered version is more robust.

  • RasWIK - Raspberry Pi Wireless Inventors Kit (CIS-S005)

    Product description

    The Wireless Inventors Kit for the Raspberry Pi (RasWIK) is an exciting and affordable addition to the Raspberry Pi.  RasWIK demonstrates that with our leading edge technology anyone (and we mean anyone) can build wireless sensors and actuators , you do not need huge experience, a degree or even any tools. We show you even how to connect the devices you build to “the Internet of Things” (IoT) service providers such as Xively. 

    Getting started is just 5 simple steps:

    • 1. Insert the preconfigured SD card to your Pi
    • 2. Plug in the Slice of Radio to the GPIO connector
    • 3. Turn on the Pi
    • 4. Power the XinoRF development board
    • 5. Launch the Python based example application on your Pi
    • That's it!........you are now past step one of your journey to wireless nirvana :)

    You can build wireless devices in just a matter of minutes.  All the code is fully Open Source, you can use, modify and even sell your own products based on this kit. 

    There are 29 fully documented projects. The 17 hardware projects take you from very basic sensors, actuators and light controls to more complicated ones that include measuring temperature and light levels. The 12 fully completed software projects show you how to do more sophisticated stuff, including posting your measurements on the Internet. 

    Out of the box all the hardware is configured to start you off without you writing a single line of code.  The kit comes complete with an SD card image that has starter software and a fully configured Pi operating system already installed.  The devices you make are even interoperable with our off the shelf wireless devices.

    In a review of RasWIK in the October 2013 issue of Custom PC , Gareth Halfacree (co author of the Raspberry Pi manual) said: "It provides possibly the simplest platform for experimenting with wireless sensor networks I’ve ever seen."

    RasWIK  won an outstanding 5 tux in Linux Format,  saw a 4 page spread in Raspberry Pi geek and has had a number of other reviews. In every review, RasWIK comes out to be an excellent way to learn more about your Pi and wireless sensing.

    The youngest WIKer we know of is just 8 years old! If he can do it, you can too :)

    Here is a 17 minute video of a presentation on RasWIK we gave at the Cambridge Raspberry Jam on 21 September 2013. 

    Features:

    • Starter examples require no soldering
    • Comes with plug in wires and a solderless breadboard
    • 4Gb SD card image (saves you lots of Pi configuration)
    • Examples use LLAP to drive the devices (LLAP devices can be mixed with our out the box wireless devices)
    • Made in the UK

  • Ultrasonic Distance Sensor (Panning) CrumbleBot Addon (BOTSONPAN)
    Panning Ultrasonic Distance Sensor for CrumbleBot

    This a simple, screw-together addon for all versions of CrumbleBot. Using the 2 mounting holes at the front, together with the power supply extension pieces (included) you can easily add distance sensing to your CrumbleBot.

    This version of the kit includes a servo to allow you to move the ultrasonic sensor left and right, using the inbuilt Crumble software commands.

    Using two Croc Clips, one for the servo and one for the for the sensor reading, as well as Crumble Software 25.2 or later, you can check if the CrumbleBot is about to hit an obstacle then avoid using a more sophisticated algorithm than just a static (non-moving) sensor. Of course, you can simply not move the sensor and use the simple software shown in the static sensor listing

    The program shown above detects an obstacle within 15cm, then looks left and right to see which direction has the closest obstacle. It then reverses out of the way of the current obstacle, before turning towards the direction with most space to move.

    No soldering is required, and the kit can be assembled in a few minutes using only a small philips (cross head) screwdriver

    Contents:
    • Ready assembled ultrasonic PCB (moving)
    • Ready assembled servo PCB (static)

  • Adafruit Sewing Needles - Pack of 20 (NEEDLES)
    Adafruit Sewing Needles

    Mighty needles, sew like the wind! This needle set is the only one you'll need for any sort of hand sewing, especially using our conductive thread and wearable electronics parts.

    Each pack contains 20 gold-eye sharps, with eye sizes ranging from #3 (1.75" long) to #9 (1.35" long). The two #3's (the largest) are too large to pass through the sewable coin cell holder but otherwise are easy to use and thread. The four #9's (the smallest) are a little difficult to thread so you may not want to use them with our conductive thread - they'll be easier to use with normal thread however. The remaining 14 needles are perfect for use with our 2-ply stainless conductive thread or stainless conductive thin yarn

  • 2-Pin Mini Slim Tact Switch - Pack of 4 (TACTSLIM)
    Pack of 4 slim tactile push button switches. Suitable for breadboards or use with the Pi TFT Screen

    Slim clicky momentary switches are standard input "buttons" on electronic projects. These are half the width of classic 6mm tactile switches so they line up better on a breadboard, just plug them into every-other row. These work best in a PCB but can be used on a solderless breadboard as shown in this tutorial. The two pins are normally open (disconnected) and when the button is pressed they are momentarily closed.
