As an experiment, I looked at using the TAG too l to collect my tweets on the CAS conference. Used the TAGS searchable link  http://bit.ly/2rMnqLd Good morning #casconf17 pic.twitter.com/DfXI6iIWYZ — Lorraine Underwood (@LMcUnderwood) June 17, 2017 Mark Guzdial plenary talk #casconf17 pic.twitter.com/ssa97bGmdF — Dr Scott Turner (@scottturneruon) June 17, 2017 Talking about prediction #CASconf17 pic.twitter.com/yTNAPm1r68 — Dr Scott Turner (@scottturneruon) June 17, 2017 Parson's problems https://t.co/XhQQYDh87L #CASconf17 pic.twitter.com/sgTN0td7K0 — Dr Scott Turner (@scottturneruon) June 17, 2017 Great to hear more on @jobadge s Iron Man project #CASconf17 pic.twitter.com/NCT3XVylSs — Dr Scott Turner (@scottturneruon) June 17, 2017 It was good a session. #CASconf17 thank you @MattWarney @mrradburn for a good session https://t.co/80ECK0R2h6 — Dr Scott Turner (@scottturneruon) June 17, 2017 Interesting insights on teaching ...

I recently received my Airblock drone from Makeblock funded through a kickstarter. If you want to see an Airblock in action this very funny video showing it being un-boxed from the Channel 5's Gadget Shown is worth a look.  Of course I had to play with it in Air mode, it is a drone I want to see it fly. But there options for creating hovercraft and your own designs. It is controllable via an app either by directly controlling or through Makeblock's own block based programming language Makeblock both are in the same app which is a feature I particularly liked. It can be annoying have to multiple apps for the same product. Selecting Air Mode (as below) means you can control it directly or chose New Project to program it. In a new project, in design mode you can set up the interface dragging buttons into the project and then write code to go behind them. I found I needed to add a power switch in the interface.   Click on the button and you can dr...

I wanted to contol the CBiS micro:Bit Car via gestures whilst holding another micro:Bit (see Figure 1) I went for: - Button A in combination with moving the micro:bit left or right, moves 'Car' forwards or backwards; - Button B in combination with moving the micro:bit rotated forward or backwards, turns the 'Car' left or right; Perhaps not the most logical combination but fun. Figure 1: CBiS micro:bit car and 'controller' micro:bit The inspiration from this remote car idea came from four sources - CBiS Education site and seeing them demonstrating it; - Technology with Save Us Micro:bot Radio Control website  ; - DrBadgr blog on the Lunch Box robot ; - A twitter conversation @jobadge @scottturneruon #simples pic.twitter.com/1pXJEyNrSn — Lorraine Underwood (@LMcUnderwood) May 1, 2017 The approach taken is simple; the Controller micro:bit has the following operations (see Figure 2 for the PXT code) Buttons A+B ...

As a bit of fun some videos using Anki's Cozmo. Did really mean for this one to be as dark as this. Moody Cozmo - Normally happy, but just don't put it on it's side.

Recently bought a Bigtrak Rover, kind of the smaller 'sibling' of a Bigtrak (see above).  Mobile Phone It has the some of the same functionality as the Bigtrak, though no cannon sound. Control is via an iPhone or Android phone app, giving the same direction and number of steps functions (see below) found on the larger Bigtrak. Control via another device. What is different to the Bigtrak is it can be controlled remotely from a PC, Mac or Tablet via a web interface. It also uses the phone's camera to provide a video stream and remote control via on-screen controls. What it doesn't have is programmable control (or I haven't found it yet). The web interface is Flash based; so there may be problems running this on iPads. Overall A Nice, little robot that use the phone to control the robot.  A set of cones gives the option of setting up an obstacle course. Once the app is installed it is very easy to get going with this.  Wou...

At PiWars 2017 (1st-2nd April 2017), thanks to the generosity of CBiS Education , I now have one of their  BBC micro:bit RobotCar ™  . It is a sturdy bit of kit, encased in an aluminum chassis with a clear acrylic screen - it feels substantial when you pick it up.  It is based around fours motors, control by a Micro:Bit, via L298N based motor controller/shield. Batteries power, 8 AAs, the motors and a Lithium powerbank to power the Micro:Bit - all included.  More information about the technical details and example software can be found on their site  https://www.cbis.education/robotic-car-kit#  including further details on the  L298N based motor controller/shield, which I found useful for programming it.   I have experimented briefly with programming it in Python (micropython), getting it to it move forward, backward; to the right and left, using the Mu editor.  The code is shown below for those who want to try i...

I was only able to stay at Pi Wars for a short while on Saturday 1st April. Even so, as a spectator, it was good fun. Here are a few pictures (and a video) for the day. Skittles - The course designers don't make anything easy. Golf Course Obstacle Course  It was not all robots, here is a Pi Controlled Drum Machine My new toys All opinions in this blog are the Author's and should not in any way be seen as reflecting the views of any organisation the Author has any association with.
