  • Crumbliser Pack of 5 - Make your own Simple Crumbs for Crumble (CRMBLSR5)
    Crumbliser - Pack of Five
    Add croc-clip-friendly connection points to your own components.

    Each Crumbliser has 4 croc-clip and 5mm screw-terminal friendly connections. as well as 4 edge fingers with pin holes on 0.1" spacing which exactly match standard pin headers.

    The croc clip connections are connected on the PCB to the 4 edge fingers.

    If you attach a 4-way female header to the finger pin holes then you can immediately break-out 4 pins of a standard header (eg. Raspberry Pi GPIO) to croc clip connectors - very useful that!

  • 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!

    Crumble Getting Started Guide

    The Crumble is an easy-to-use programmable controller. It can drive 2 motors forwards and backwards at variable speeds. It has 4 IO (Input/Output) pads which allow connections to switches, LDRs, low power LEDs and so on.

    Basic Connections

    The Crumble has been designed to encourage tinkering, using ‘croc leads’ for quick and simple connections. Pads allow terminal blocks to be fitted or a direct solder connection made, while the larger 4mm holes make an easy target for conductive thread and needle.

    Crumble with croc leads

    The Crumble software runs on PC, Mac and, in the near future, Linux (including the Raspberry Pi). Inspired by MIT Scratch, programs are simply built by snapping blocks together on screen. Sending a program to the Crumble is almost instant, allowing rapid experimentation.

    The Crumble can be extended with digitally controlled full-colour LED, called Sparkles. Additionally, several expansions board (Crumbs) are also in the works.

    Genuino (Arduino) Micro

    Code: GBX00053

    Genuino, the new name for Genuine, Official Arduino

     


    Genuino Micro is a microcontroller board based on the ATmega32u4, developed in conjunction with Adafruit. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable to get started.

  • 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)
