Strictly Cube:Bit

In previous posts I looked at using the 4Tronix Cube:Bit with Python (http://bit.ly/2DcXcei) or Adafruit Circuit Playground with MakeCode (http://bit.ly/2T0ddcN) both used to make a 'Disco-Light' essentially reacting to vibrations from a speaker and therefore indirectly react to music.

 In this post, a short experiment with the Cube:Bit combined with MakeCode is shown. First thing once you are in https://makecode.microbit.org/# is to add the MakeCode package for the Cube released by 4tronix; details on setting this up are at https://4tronix.co.uk/blog/?p=1770.

 So the basic (and it is basic) idea in the code, is change one of the pixel/LEDs colour in response to the acceleration in the three axes, with each axis controlling either the amount of Red, Green or Blue in the LED's output. The colour is shifted one pixel along each time and the process repeats. The effect is run the colours through all the LEDs. The code is shown below:





One of the other things of found I quite enjoy doing with it; is putting the cube at different angles and see what colours are produced.

Robot Software

In the previous blog posts for this 'series' "It is a good time...."  Post 1  looked at the hardware unpinning some of this positive rise in robots; Post 2  looked at social robots; Post 3  looked at a collection of small robots; Post 4 looked at further examples of small robots Robots, such as the forthcoming Buddy and JIBO, will be based some established open sourceand other technologies. Jibo will be based around various technologies including Electron and JavaScript (for more details see:  http://blog.jibo.com/2015/07/29/jibo-making-development-readily-accessible-to-all-developers/ ). Buddy is expected to be developed around tools for Unity3d, Arduino and OpenCV, and support Python, C++, C#, Java and JavaScript (for more details see http://www.roboticstrends.com/article/customize_your_buddy_companion_robot_with_this_software_development_kit ).  This post contin ues with some of the software being used with the smaller robots.  A number ...

Speech Recognition in Scratch 3 - turning Hello into Bonjour!

The Raspberry Pi Foundation recently released a programming activity Alien Language , with support Dale from Machine Learning for Kids , that is a brilliant use of Scratch 3 - Speech Recognition to control a sprite in an alien language. Do the activity, and it is very much worth doing, and it will make sense! I  would also recommend going to the  machinelearningforkids.co.uk   site anyway it is full of exciting things to do (for example loads of activities  https://machinelearningforkids.co.uk/#!/worksheets  ) . Scratch 3 has lots of extensions that are accessible through the Extension button in the Scratch 3 editor (see below) which add new fun new blocks to play with. The critical thing for this post is  Machine Learning for Kids  have created a Scratch 3 template with their own extensions for Scratch 3 within it  https://machinelearningforkids.co.uk/scratch3/ . One of which is a Speech to Text extension (see below). You must use this one ...

Scratch and web-cams in Scratch 3

Scratch 3 was launched on 2nd January 2019, so I wanted to know would Webcams still work with Scratch 3 as it did with Scratch 2. For example, in a previous post  Scratch, webcams, cats and explosions  the cat (Scratch) moved across the screen and a button burst when the object moved in the camera onto it.  Can the same thing be done in Scratch 3? The short answer is yes, but it is done slightly differently. The first change the video capture is not there in the blocks automatically; but is an extension that needs to be added. First, you need to add the extension blocks for video sensing. Go to the little icon at the bottom left of the screen (as shown below) this takes you to the extensions menu. Next, find the Video Sensing option and selected. The webcam, if enabled, with start automatically. A video sensing set of blocks is now in the list of block options.  The rest is very similar to doing this in Scratch 2. Moving ...
