The good people at Pi Supply sent a rather generous swag box to review and I have been busy playing – sorry TESTING the expEYES module from the Phoenix Project in New Delhi the last week or so. The expEYES Junior is described as a ‘Science Learning and Experiment Kit’ which in some ways is selling the module a bit short. Sure at a price tag of £50 it is not cheap , but then the expEYES kit is not an ‘educational toy’ hence the Science and Learning tag. As mentioned I feel the module is somewhat undersold for a few very good reasons. It CAN work as a 4 channel PC oscilloscope; OK maybe not high grade but for a KS3 Science lesson – great value added. The expEYES will work as a waveform generator (SINE) and will also display squarewave readouts on all four channels apart from more traditional measuring and quantifying of analogue inputs. Could I also ask my faithful follower(s) if they have encountered a unit like this that is programmable with Python ? Please leave a comment below if you do – as mentioned this is a very capable little kit.

So what is in the box , I hear you say – well apart from the main module , USB cable and a CD containing software there is a selection of resistors LED’s, capacitors and some pre-cut jumper cables. The inclusion of the screwdriver for the terminals is a nice gesture, this is the only tool you will need for setting up any of the experiments.

The kit contains all components necessary to perform a great variety of science, technology and electronic experiments.

It has to be said that this kit is not ‘polished’ in terms of presentation, packaging and finish of components – but it is honest ‘whatyouseeiswhatyouget’. You might have to try a bit harder at undoing some of the terminal screws at first, wire ends are not soldered or capped possibly resulting in frayed ends and sore fingers. I will also suggest that the documentation is made a bit more ‘Junior’ friendly as the tag ‘Junior’ infers – you’re looking at  a very gifted young person to go through some of the experiments. That is NOT to say that I suggest dumbing down – merely clarifying assembly diagrams and making the instructions ‘bitesize’  will easily justify the term ‘Junior’.

And this is where i argue the value of £50 to be worth every penny – the thought and skill in devising the experiments are great if not inspirational for any person regardless of age. The  breadth of experiments and scope for learning makes this a great companion for a secondary school, easily extended into post-16. As you have guessed already I am evaluating the expEYES from an ‘educators’ point of view – I would NOT hesitate in recommending any parent to  invest in this kit for their child’s education. I’ll even go one further and say that anyone finding a fully functional USB oscilloscope with these capabilities for £50 is a wizard or a ‘giant pork pie slinger’.

OK enough ‘teaching & learning’ jabber we’re ready to go; let’s get experimenting and have some fun with expEYES.  I’m not going to cover installation of software at this stage – this is merely a 1st brief overview of capability. I have tested the software on Linux Ubuntu and Linux Mint (latest distros) and wait for it . . . drumroll . . .  yes  . . . RaspberryPi   !!


. . . . hands on Linux / Debian testing coming up very soon   . . .

    Just came across this old review and thought that you would be interested to know that a new version of expeyes has been released with much better documentation and easier to use. It has over 50 well documented experiments with pop-up helps.
