Experiences with Raspberry Pi Touch Screen

Well for once I am not going to be talking about robots, but my experience in setting up a Raspberry Pi touch screen - this is not a how to guide, a couple links to those are included in the post, but my experience of setting one up.

So the I bought the Raspberry Pi Touch Screen from Pimoroni and along with the stand/frame for it.

Setting up the LCD frame was simple with the instructions provided and the link at the end of the instructions provide some further help http://learn.pimoroni.com/tutorial/pi-lcd/getting-started-with-raspberry-pi-7-touchscreen-lcd on setting up the screen

A tutorial from The PiHut (https://thepihut.com/blogs/raspberry-pi-tutorials/45295044-raspberry-pi-7-touch-screen-assembly-guide) was very useful on how to connect the screen to the Pi. The blue side on the white ribbon cable (provided with the screen) used in connecting the two together needs to blue side down towards the LCD (as explained in PiHut tutorial) and facing away from the Pi when connecting to it, which is the bit I was unsure of. Connecting the power via the jumper leads that came with the screen means only a single power supply is need for both the screen and Pi. If you follow the PiHut tutorial the colours of the jumper leads may needed to be changed but that is not a problem.

I used Raspbian OS and when power up with a power lead (it needs to output enough current to power both devices) both the Pi and screen came on without any difficulty.

The touchscreen worked well as a mouse and the single power lead makes the system much more compact.

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 ...

WebVR 3 Playtime: Augmented Reality

I am going to try to persuade you that using A-Frame it is not hard to do some simple Augmented Reality (AR) for free, via a browser, but that also can run on a mobile device. Introduction This is part of a short series of articles about some experiments with WebVR Web-based Virtual Reality - in this case based on the wonderful A-Frame ( https://aframe.io ) . In the first post WebVR playtime 1: Basics of setting up, images and rotating blocks , I looked at setting up a scene and then rotating an object. In the second pos t, recapped the basics, then look at adding video, 360 degree video, and models developed elsewhere. In this post we are going to start looking at using WebVR as part of an augmented reality solution. I going to start by building on the great resource Creating Augmented Reality with AR.js and A-Frame by Jerome Etienne, creator of AR.js - the starting code below and the basis of the solution ...
