  • Bit:Bot Robot for BBC Micro:Bit (BitBot for MicroBit) (BITBOT)
    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)

    Learn here how to control the Bit:Bot with your Bluetooth phone

     *NEW* There is now a Microsoft PXT package for Bit:Bot (thanks to Sten Roger Sandvik, @stenrs on Twitter). Go to the Advanced tab or the Tools gear icon and select Add Package, then search for BitBot
     

    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.

  • PiStep2 Dual/Quad Stepper Motor Control Board for Raspberry Pi (PISTEP2D/Q)

    Dual/Quad Stepper Motor Control Board for Raspberry Pi

    Fully Assembled - No Soldering Required

    Raspberry Pi Zero Form Factor - works with all versions of Raspberry Pi with 40pin GPIO connector

    Stepper motors (optional extra) and Raspberry Pi not included


    Available in either Dual (2 steppers) or Quad (4 steppers) versions

    Various Power Options:
    1. Powered from the Raspberry Pi 5V
    2. From the 2-pin Terminal (whatever voltage is required for the motors)
    3. Micro-USB - 5V only
    This neat little board plugs directly into the Raspberry Pi GPIO header and provides 2 or 4 connectors for our small stepper motors 28BYJ-48

    Pinout is simple:
    • Physical pins 11, 12, 13, 15 for Motor A (GPIO 17, 18, 27, 22)
    • Physical pins 16, 18, 22, 7 for Motor B (GPIO 23, 24, 25, 04)
    • Physical pins 33, 32, 31, 29 for Motor C (GPIO 13,12,6,5)
    • Physical Pins 38, 37, 36, 35 for Motor D (GPIO 20,26,16,19)
       

    Each pin has an associated white LED so you can see the stepper signals going through

    Power Supply Alternatives

    • Jumper VCC-VSTP (default). Power from the motors is taken from the Raspberry Pi 5V line
      • Micro-USB into Raspberry Pi. 5V for the Pi and the stepper motors goes through a poly-fuse which can trip if 2 motors are used simultaneously
      • Micro-USB into the PiStep board. 5V for both the Pi and the stepper motors is provided directly from the 5V USB input so no problems with 2 motors at once
    • Jumper VSTP-VIN. Power for the motors is provided from the 2-pin screw terminal, so can be any voltage that the steppers can handle. Ensure you use the correct polarity! We recommend to keep it below 12V. You will find that the stepper motors can go up to 9V and will be able to step faster, the higher the voltage that is applied, but there will be some deterioration of the life of the stepper motor at a higher voltage.



    Python Programming
    Please see the excellent example here for some pointers. You will need to change the pin numbers as above and also change the speed so it steps at a visible rate. You may also want to remove the print statements to speed it up. The lines in Red below are changed from the original to operate Motor A.

    # Use BCM GPIO references
    # instead of physical pin numbers
    GPIO.setmode(GPIO.BCM)

    # Define GPIO signals to use
    # Pins 18,22,24,26
    # GPIO24,GPIO25,GPIO8,GPIO7
    StepPins = [17,18,27,22]

    # Set all pins as output
    for pin in StepPins:
      print "Setup pins"
      GPIO.setup(pin,GPIO.OUT)
      GPIO.output(pin, False)

    # Define some settings
    StepCounter = 0
    WaitTime = 0.01



    ScratchGPIO Programming

    These pins are identical to those required by ScratchGPIO and therefore can easily be driven using simple Scratch commands:
    Set motor type for Scratch to be Stepper motor

    Set the position of the stepper motor A

    Set the speed of the stepper motor A

  • 12mm Flat/Square 5V Digital RGB LED Pixels Strand of 50 WS2801 Waterproof IP65 (LED50-2801-5A)

    12mm Flat/Square 5V Digital RGB LED Pixel String - Waterproof IP65

    NB. Photos show shorter strand, but this strand has 50 LEDs

    RGB Pixels are digitally-controllable lights you can set to any color, or animate. Each RGB LED and controller chip is molded into a 'dot' of silicone. The dots are weatherproof and rugged. There are four flanges molded in so that you can 'push' them into a 12mm drill hole in any material up to 1.5mm/0.06" thick. They're typically used to make outdoor signs. These pixels are round, but we also have some with a flat square back. It affects mostly the way the wires lie and the colour of the wires!

    The pixels are connected by a 4-conductor cable. +5V (Red), Ground (Yellow), Data (Green) and Clock (Blue). Data is shifted down from one pixel to the next so that you can easily cut the strand or attach more onto the end.

    Each dot is digitally controlled, with an internal 8-bit PWM LED driver (24-bit color for 16 million different shades). The pixels must be clocked by a microcontroller, we have an example code linked below that works on an Arduino, it should be simple to adapt it to any other microcontroller.

    The pixels use 8mm diffused RGB LEDs, with a 120 degree beam width. The total max brightness of all LEDs is about 1600mcd but with the light more evenly distributed & mixed than a clear LED. (Please note: mcd ratings of LEDs are notoriously inflated by most LED sellers, so be extra-skeptical when reviewing LED ratings!)

    Sold by the strand, each strand has 50 pixels in series! Each strand has two JST SM 4-pin connectors so you can connect multiple strands in a row, as many as you wish, just watch for how much current they want. We now have LED pixel strands with the power wires (Red & White) spliced out so its really easy to connect 5VDC.

    You can drive these with an Arduino using any two microcontroller digital pins, check this library which also has example code to demonstrate the strands and be sure to read Adafruit's detailed tutorial on usage!

    You can also download the FastSPI library and our Chaser.ino sketch. Connect the Data wire (Blue) to Pin 11 and Clock (Green) to Pin 13 as well as Power and Ground

    • 12mm diameter (0.45") 75mm deep (1.5")
    • 80mm / 3" apart between each pixel
    • 50 pieces per string
    • These pixels use a WS2801 chip for full 24 bit color
    • 5V power, 60mA maximum per pixel (LED on full white)
    • Maximum current required 3A per string
    • 2-pin SPI-like protocol
    • Brightness: Red = 3.3 Lumens/300 mcd, Green = 10 Lumens/1000 mcd, Blue = 2.7 Lumens/300 mcd (mcd calculation based on full 120 degree beam)

  • MeArm - The Robot Arm taking the world by storm (MEARM)
    The MeArm is a fantastic, low-cost and easy to build robotic arm with a natty little gripper. It comes complete with all the fixings and 4 servos you need to assemble it.

    All the files for the MeArm are open-source so if you fancy building one for as little money as possible, please give it a go.


    The latest version is a stable base model and that's what you see here today. It ships with all the acrylic parts you'll need as well as all of the fixings and four hobby servos.

    The most recent instructions for the #meArm are available as a pdf and at instructables.com

    Our basic testing has involved driving the servos straight from an Arduino, using a simple shield and four 10k Ohm potentiometers. The code for that can be found in the MeArm Github

    Software exists for the Arduino, Raspberry Pi, Beaglebone Black and Espruino, as the MeArm community is amazing!

  • Adafruit NeoPixel Ring - 16 x WS2812 5050 RGB LED with Integrated Drivers (ADA-NRING16)

    Adafruit NeoPixel Ring - 16 x WS2812 5050 RGB LEDs (Model #1463)

    Round and round and round they go! 16 ultra bright smart LED NeoPixels are arranged in a circle with 1.75" (44.5mm) outer diameter. The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the colour will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC (4-7V works) and you're ready to rock.

    There is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microconroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the netduino or Basic Stamp. Adafruit's wonderfully-written Neopixel library for Arduino supports these pixels! As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around. An 8MHz or faster processor is required.

    Comes as a single ring with 16 individually addressable RGB LEDs assembled and tested.
