Basics of Iterative Design: Crumble Ball Launcher

One of the most crucial parts of any design-based work is the process of iteration. Put simply, it is the process of Design, Prototype, Evaluate. Improving our thoughts and ideas, and accepting that our own work will likely never be perfect and will always have room for improvement are important skills. It is also important as some problems with a design may only be discovered whilst making or using a product. Iterative design irons out the wrinkles, and makes for a better end result.

To give the process a go, we decided to make a ping pong ball launcher, using the Crumble. There was, however, a crucial design constraint. Could we design one whose only powered part was a servo?

It is worth noting at this point that this isn’t necessarily a project you SHOULD do with students, unless you can definitely trust them.

After thinking for a while, we came up with our first design: a trebuchet-inspired design with the servo providing the ‘throwing force’. If the servo is capable of launching a ping pong ball, then this method should prove it.

After extending the main launch arm to the point at which it is almost too heavy, we can say that it doesn’t work very well. It definitely shifts a ping pong ball, but it doesn’t have enough velocity to keep traveling very far.

After prototyping and evaluating the first main design, we decided to go down a different route. We were inspired by a cardboard ping pong ball launcher that we found on YouTube after some research. We realised that we could use a similar firing mechanism, which uses a rubber band to provide some elastic potential energy. The servo could then be used to release the mechanism, hitting and launching the ball.

Our first attempt was much more promising. It successfully launched the ping pong ball a surprising distance! There were, however, some improvements to be made. We decided first of all to address the point of contact between the aluminium rod and the ball. We thought that area wasn’t big enough, so we 3D printed an adapter for the end.

We added the adapter and launched the ball a few times – it definitely made better contact with the ball. But there were still a few issues. The servo arm would occasionally miss the main launch shaft (aluminium rod), the body was beginning to wear down from the impact of the wooden stop and the whole thing felt a bit flimsy.

Because of the success that we had had with this design, we thought that we didn’t want to come up with a new one – instead we decided to refine and model, and 3D print a big portion of it, using a lollipop stick in place of the aluminium rod, as it felt safer.

The final mechanism works really well!

Without going through the iterative design process, our design wouldn’t be anywhere near as good. This important process happens all of the time – whether it be a blog post, a leaflet or a new product. The process of evaluating and refining work is crucial.

Improving Lives – Digital White Cane

It can be hard to imagine what life would be like if you were blind. The simplest of tasks become much more difficult, and yet those who are blind can lead very full and active lives. However, one of the larger challenges they face, is navigating the hazard-ridden hustle and bustle of outdoors.

The use of a cane to aid those with visual impairments has been around for centuries , but it wasn’t until the early 20th century that the more familiar white version came into existence.

The purpose of the White Cane is to enable the user to identify obstacles on the ground, and alert other pedestrians etc., to the fact that they have a visual impairment. The basic design has stood the test of time, but what if we could improve this design by bringing it into the modern era? By adding an Ultrasonic Distance Sensor and a motor with an off-centre mass, we can create a walking aid that picks up on objects before we get close to them and vibrates depending on how close we are to them!

To make our digital version of the White Cane, we are going to combine the Crumble (for our programmable electronics), along with some other design elements, including some 3D printed parts.

As this is more of a proof-of-concept, we are not aiming for a retail-ready design. This is much more of a prototype, enabling us to try out ideas; an important part of any Design and Technology work! We have put together a list of the key features we needed to think about:

We decided on 3D printing a mount for the Ultrasonic, which would also accommodate a ping pong ball to help the cane move freely over surfaces.

The Ultrasonic slots into the mount upside down to allow easy access to the connections, and the cylindrical adapter allows a snug fit with the main body of the cane (PVC pipe).

At the other end of the cane, we wanted an ergonomic handle, so we designed and printed a core, around which we could use polymorph to create a custom grip.

To make the grip, we heated our polymorph using a heat gun (take care – it can get hot!) and then wrapped it around the handle piece and squeezed to get a custom moulding of our grip. Make sure your polymorph isn’t too hot – it will soften the PLA!

Then it was just a case of putting all of the pieces together. We used elastic bands to secure our motor mount and other Crumble components.

Finally, we just needed to program the Crumble to vibrate according to our own requirements. As a start, we got the cane to vibrate when we detected an object that is less than 50cm away.

And there we have it, our Electronic White Cane prototype! You could progress on from here in multiple ways, including, but not limited to: extending the program to make it vibrate at different rates depending on the distance away of an object; building a full-size version and testing it out by using blindfolds etc.; building a self-contained ‘finished’ version.

If you have a go at this project, or any other, we’d love to see! Get in contact with us via email, or on Facebook, Twitter or Instagram.

Using the Low-Cost FM Radio Module

Great news! We’re having a bit of a clear-out in the warehouse and as such, we have lots of fantastic deals. One of the items on offer is our Low-Cost FM Radio Module. Originally based on a commercial PCB, this module is a complete working FM Radio. It scans at the push of a button, and locks onto stations automatically.

It is a great starting point for design-based lessons, and given that there is now nearly 40% off of the RRP, it is great value for money too.

Our Low-Cost FM Radio Module

We thought that we’d have a quick go at making out own housing for the radio module. We set our sights on a simple cubic design, with a base containing the ‘Scan’ and ‘Reset’ buttons. We designed a 2D template for the main cardboard body, and then we 3D printed our other parts to make a base with buttons, a volume dial and a speaker mount.

The inside of our FM Radio

We mounted all of the internal parts to the main body, mostly using nuts and bolts. After this, we glued the body together.

Once the body had dried, we put it onto out mount. To get the effect on the switches, we used some correction fluid, which we then sanded back once it had dried. This gave us an interesting effect; almost shabby-chic.

Our finished FM Radio

Once it’s all built, it’s just a case of switching it on and tuning into your favourite stations.

If you have a go at any design work using our radio module, or any other project, we’d love to see! Get in contact with us via email, or on Facebook, Twitter or Instagram.

Pi Wars: a Story

Back in the summer of 2018, Joseph and I found ourselves at a ‘super secret’ meal after the first evening of Raspberry Fields. Apparently, staying in the same seats for the duration wasn’t allowed, and as such, we chatted to a few different people. Luckily, for our dessert, we ended up sitting opposite Michael Horne and Tim Richardson – famed for creating the infamous Pi Wars robotics competition. I had heard about the event on Twitter, and was especially interested in having a go.

To cut a long story short, I was very keen to take part! Furthermore, Joseph was definitely up for sponsoring the event with some prizes.

The good news came on the 30th of September 2018. Our application had been successful and we were set to compete in Pi Wars 2019! I was to take the reins on our entry, as Joseph is a very busy person, and as I was fairly new to python, it would be a great learning experience.

“I knew it was going to be challenging, but I hoped it would be rewarding as well”

The process of learning how to do any of this was going to be quite extensive. I’m a Raspberry Pi Certified Educator, and I had tinkered with the Pi on the odd occasion, including making a Wiimote controlled vehicle using the CamJam kit but I had never completed anything beyond this. I knew it was going to be challenging, but I hoped that it would be rewarding as well. One of the best ways to learn a programming language is to use it in context; a real application.

When discussing ideas for the robot (before we had applied), Joseph had mentioned that there was a Python library to control the Crumble over USB. This was brilliant. We could use the Pi for all of the processing power (to stick within the rules!) and the Crumble could be used as our Motor Driver board, and power any Sparkles we may want to attach.

My first step was to focus on learning Python. I’d become familiar with a couple of written/block-based languages in the past, and I had even gotten halfway through a Python course, but unfortunately it had been a while so I needed to start from scratch. I made it part way through an Udemy course, and then I started and completed the free Python course from Codeacademy. This was a big step for me. I had reached the end of a programming course, and I was feeling much more confident in getting started.

“After swearing I would get started before Christmas… January arrived”

After swearing that I would get started before Christmas, and not do my usual procrastinating, January arrived. It was very busy – we were heading to BETT this year to exhibit. I knew I wasn’t going to get started until February. As a part of a conversation with our Spanish distributor for the Crumble (Complubot), Joseph had been made aware of something very useful – The Pixy Cam.

After getting back from BETT, we looked into the Pixy2. It looked incredibly easy to use, it could detect coloured objects and lines, and it was possible to interface with it via Python – perfect! We purchased the camera, along with a pan and tilt mechanism, and couldn’t wait to get stuck in.

The included software for the camera was simple to use, and offered some great features – especially when it came to tweaking the camera’s settings to recognise colours (signatures) and lines (vectors). One of the steepest learning curves, however, involved interfacing with the camera via Python. It seemed that the device was much more suited to controlling via an Arduino than a Raspberry Pi, and as such, it was hard to find a great deal of information about using it with Python.

As a part of the installation process, four example Python programs were generated. I would rely heavily on these to work out what to do!

I was becoming overwhelmed with the ever-decreasing time left, and this caused me to take some drastic action – a mind map! I planned a very basic chassis to get something moving, and then wrote down what steps needed to be completed before the big day. This is called decomposition – breaking down a problem into smaller, more manageable pieces.

“I was feeling much better about the still mammoth task ahead”

One of my first steps was to control a motor connected to the Crumble, by using Python This would become my ‘Hello World’ style program. After this small, but important step, I was feeling much better about the still mammoth task ahead.

The remote control portion of the project was quickly finished – I had used the ApproxEng library for connecting to, and controlling motors, in the past, so it didn’t take much to adapt the code to work for the Crumble. Theoretically, that was the programming completed for half of the challenges!

The steepest learning curve, and the point at which I repeatedly questioned why I was doing any of this, was programming the autonomous challenges. After tinkering with the example Python programs, I decided to start with the Line following program. This wasn’t too difficult to do – I had experience with various algorithms for line following. Once I had worked out what information I could use from the Pixycam, it all fell into place quite quickly! After this, I set to work on driving towards a colour signature. This was with the autonomous maze in mind as I felt that this would be more challenging than the Nebula. Once I had the working maze code, I could reuse elements of it to help recognise, and correctly approach the four colours in the Nebula task.

I learnt a lot whilst programing these challenges:

  • Things fail – a lot. I spent a lot of time thinking, staring at code trying to make sense of why it wasn’t working.
  • Take breaks. I regularly found myself slumped at my desk, getting increasingly frustrated. I stopped, came back to it the next day and more often than not, immediately solved my issue.
  • Don’t be afraid to redo something. Some of the functions I had written were messy, and didn’t work properly. A whole new line of thinking enabled me to produce better, and more efficient code!
  • Not everything has to be perfect. This is was an amateur robotics competition, of which I am a beginner. It was better to have something clunky but working, than something that doesn’t work at all. The day before the competition, in consultation with Joseph, I decided to put my ‘fancy’ maze following code to bed, and develop a simpler version. Given that the maze was preset, and we had access to the plan, why would I even bother looking for the next alien to the left, if i knew it was a right turn?

We both thoroughly enjoyed our time at Pi Wars. It was a day of both success and failure, but it was a very rewarding task to undertake. I managed to battle my way through to the Grand Final of Pi Noon ( a 1v1 balloon popping battle), coming second after a close final. But more surprisingly, we won the beginner category! Our slow, solid and steady Crumble Robot had powered its way round to victory!

Here are just a few pictures from the day!

This whole experience has proven that one of the best ways to learn programming is to give it a context. Trying to learn something whilst not giving it a real-life context makes it very difficult, and it doesn’t ‘stick’. It is worth mentioning that this is one of the main ideas behind physical computing – blurring the lines between a computer and physical components and pieces. Programming and controlling something that you’ve made yourself gives you a fantastic feeling, and I definitely have a stronger urge to continue, more so than in the past.

What do LEGO® Bricks, Mars and Football have in Common? Seismology!

On 5th May 2018, the InSight Mission to Mars was launched

The InSight Mission will put seismometers onto the surface of Mars to feel for ‘Marsquakes’  – geological activity like our Earthquakes. It has been 40 years since seismometers were last placed on the planet, using the Viking landers. However, it is the first time a seismometer will be placed directly onto Mars’ surface.

InSight successfully landed on Martian soil on Monday 26th November 2018 at 19:33 UTC.

Once the lander has got to work, scientists hope to receive the first  of its data in early 2019.

Along with the seismometer, the InSight has on board a host of other tools and sensors including: environmental sensors like wind and pressure, to help eliminate false positives with the seismometer; very precise radio transmitters, to help map the wobbles in how Mars rotates, allowing us to figure out whether Mars’ core is solid or liquid; and finally, a five meter long heat probe, which will bore itself into the surface of Mars, allowing scientists to monitor how heat travels through the planet.  All in all, we will hopefully be able to finally work out the makeup of Mars, and whether or not it shares similarities with our own planet and moon. This will then allow us to have a greater understanding of how our Solar System was born.

Alongside this amazing InSight mission, the British Geological Survey (BGS) have created a set of teaching resources and classroom activities (Project MarsQuake) which, when they become available, will utilise and share the latest images and data coming back from InSight.

Seismology with LEGO® Bricks?

As a part of this set of projects and resources, Paul Denton (BGS), worked with us here at Mindsets, to create our very own easy to use and accessible seismology tools. You may have already spotted them on our website, but we want to formally introduce the ‘Build your own Seismometer Kit’  along with the SeismicPi HAT.

The Build your own Seismometer Kit provides you with all of the parts needed to create your own seismometer – out of official LEGO® bricks! 

To understand the data coming from the seismometer kit, you need a device to ‘read’ it (a digitiser). The SeismicPi HAT digitiser was developed as a part of the MarsQuake project, alongside a BGS-led summer school project at the University of Cambridge. This unique device can be used with up to four seismometers, and can be connected to a PC via USB. It can also function as a HAT for a Raspberry Pi.

The Football Connection

During Leicester City Football Club’s (LCFC) infamous 2015-16 Premiership-winning season, they were obviously doing very well. During the second half of that season (2016), students from Leicester University, in partnership with the BGS, started a very unusual outreach project. Hazel Community Primary School, conveniently located less than 500m away from the King Power Stadium (home of LCFC), became the project’s new home, along with a seismometer.

Every time a goal was scored by LCFC, the crowd went wild; more so towards the end of their amazing season. These celebrations caused vibrations within the ground and, you guessed it, could be picked up by the seismometer inside Hazel Community Primary School. The ‘FootyQuakes’ soon became ‘VardyQuakes’, after LCFC’s star striker, Jamie Vardy.

Hazel Road School's LEGO-based seismometer picking up goals.

For the 2016-17 season, the school’s seismometer was replaced with a simple LEGO®-based seismometer, based upon the idea of a ‘Build your own Seismometer Kit’. More recently, following on from the success of the VardyQuake Project, the National Youth Agency in Leicester commissioned us to produce a special version of the seismometer kit, which will be in Blue and White – after LCFC’s home colours.

More than 50 sets worth of Blue and White LEGO® bricks.

Global STEM Launch and the Scottish Learning Festival

Last week was a very busy week for us here at Mindsets. We attended two different events, one in York, and the other in Glasgow! This meant one thing – road trip!

Tuesday saw the official launch event of the ‘Global STEM Award‘ , by UK STEM, at the highly-acclaimed National STEM Centre in York. We were there to integrate our products into the Global STEM Award, and all in all, it was a brilliant day. The event was well attended, with over 90 students from local schools, and as far afield as China! The Chinese students were on a trip to the UK, partially organised by Mike Cargill (Director, UK STEM), and it made sense to have more of a global audience for the launch of the Global STEM Award.

After Tuesday’s launch, we drove straight up to Glasgow, to set up for the Scottish Learning Festival. We knew it was going to be tight – but we managed to arrive with 30 minutes to set up – and we finished with time to spare! After our very busy day, we decided it was time to unwind…

We were at the Scottish Festival of Learning mainly to exhibit the Crumble. We are finding that whilst the Crumble is well established in England and Wales, it seems that most of Scotland haven’t heard of us! It definitely made sense to exhibit.

We had a great couple of days at the exhibition, and we had a great number of interesting conversations, with some fantastic people. Everyone was pleasantly surprised to find out how easy to use the Crumble is, and how it’s a perfect first step into the world of Physical Computing.

I’ve got a Crumble Starter Kit – now what?

note: some links in this post go direct the the home of the Crumble, Redfern Electronics.

You’ve been lucky enough to get your hands on a Crumble starter kit, you’ve connected bits together and managed to get a Sparkle shining red, but now what? What else can you do with it apart from make a red light?

We’ve decided to collate a list of inspiration and ideas for projects that you can make using only the contents – and container – of the starter kit.

We’ll start with the simpler projects, before looking at a couple of more advanced ones. First up we have a simple timer. This can be made as simple or advanced as you like, but the main premise behind it is that a timer for 30 seconds will start when you press the button.

The program is simple. Wait until the button is pressed, turn on the Sparkle white, then after 30 seconds, turn it off. The program then repeats, waiting for the user to press the button to start the timer again. This could easily be extended by adding in a nice pulsing effect every second, getting faster near the end of the time limit.

Next up we have the classic ‘police lights’ project. You can start off by making only the lights, which you can then ’embed’ into a model police car. If you are feeling particularly creative, you could use the starter kit box to make a chassis, which you can then turn into your own ‘moving’ vehicle! As a starting point, we want to make the two sparkles alternate between red and blue. This could then be elaborated on, to create extravagant flashing patterns, or even use the switch to cycle between various styles!

This is one of the simplest, yet most satisfying programs! To represent police lights, we turn the Sparkles on red and blue, then after a short time, we switch their colour.

Now we have an example of a simple project, with a bit more ‘making’ involved. The lightbox is made using either the starter kit box, or another box, and a piece of paper. We then can light up the message using the supplied sparkles. To make the programming more difficult, we can control the lights via the switch, make them change colour or even fade through the RGB values.

The programming for this project is surprisingly simple, once you know how. We are going to wait for the button to be pressed, and A to become HI. Then we’ll turn on the Sparkle(s) white (you can use as many as you like with this code!). Then, each time the button is pressed, the Sparkle(s) changes to another colour, or off. The wait statement allows us time to remove our finger from the button, setting A LO. If we didn’t have it, the program would skip through repeatedly, as it runs faster than we can move!

For our final basic project, we have our very own model Zebra crossing, complete with flashing Belisha beacons! Using most of the starter kit box as the ‘crossing’, we’ve made two beacons out of  some of the lid from the box. Programmatically, this isn’t too taxing – its an infinite loop, alternating each light.

This code is nice and simple – set one Sparkle to Orange, and the other one off. After one second, switch them around so that the orange one turns off, and the one that’s off turns on orange. Wait another second before repeating. This will then give us the effect of them flashing alternately.

Now we move onto some projects for those of you who are more experienced. First up, we are going to look at a simple reaction time gamer. One Sparkle will light up after x milliseconds, then you have to press the button as quickly as you can. Within a set amount of time, and you get a green on the other Sparkle, but too slow and you’ll get red.

Now that we have moved onto something more complicated, the code has gotten longer, however, it is just as easy to understand! This program waits a random amount of time (0.5 – 3.5 seconds) before turning on the Sparkle white. It then ‘times’ us by adding 10 to our ‘Time’ variable, every 10ms, until the switch is pressed. If we took less than 350ms, we get a green flashing Sparkle, but if we took longer, it goes red! If you have a Sparkle Baton, check out this project.

On the theme of reaction-based games, we have our ‘Sparkle Snap’ game – The two Sparkles light up a random colour (from a predefined list), if they match you must press the button as quickly as you can. Succeed, and you’ll be rewarded with flashing green Sparkles. Get it wrong, and you’ll get red.

We’re starting off by lighting each Sparkle one of three colours. We’ve assigned ‘ColourOne’ and ‘ColourTwo’ a random number between 0 and 2, and then using selection (if statements), we’ve lit the Sparkles depending on the variable values. It’s worth noting that this section could be far longer, if you want a wider range of colours. The Sparkles are then on for either 500ms or until the button is pressed. If the time elapses, the game just continues, whereas if the button was pressed, we check to see whether the two colours (variables) are the same. If they are, then we flash green for 2.5s, if they weren’t, then we flash red for 2.5s. This game could be taken a lot further if you wanted too – making it get faster after each correct guess, adding in a penalty if you miss a pair etc.

Next up we have a slightly simpler project to the previous two – morse code. Using a Sparkle, it is possible to flash an array of messages, using morse code. This one is fairly self-explanatory, and using a variety of wait statements and repeat loops, it is easily achieved.

This is the less efficient way of making this program, but it works nonetheless! Put simply, we have flashed our Sparkle based on something in Morse Code. This is achieved by using the wait statements, to correctly display a dot, dash, the gap between letters and the gap between words. If you want another starter kit, ‘code’ based Sparkle project, check out our Lighthouse.

Finally, we have another ‘maker’ based project, using the starter kit box (or other). By colouring the box in black, and poking some carefully placed holes, we can easily make a ‘constellation’. We can then add some realistic twinkling, by randomly choosing shades of bluey-yellowy-white. Although simple to make, it is a nice programming exercise using repeat loops and variables.

Our last code segment is actually quite simple. By defining the range of various random number blocks, and placing them in the RGB sections of the Sparkle variables, we can define a random set of colours. Then, by waiting a random amount of time for changing them, we can get a realistic twinkling effect!

There are numerous possibilities when it comes to deciding ‘what to make’ using the starter kit – many more than we’ve listed here. Hopefully you’re now feeling more inspired, and have some fantastic ideas of what to make at home, or with your class. If you have other Crumbs and components laying around, don’t forget to head over to our Projects to see what else you can make.

Have a cool idea that we’ve not listed here? Please don’t hesitate to drop us a message on our contact us page, or Twitter!

Mindsets and Machine Realm have launched a Kickstarter

UPDATE: You can find the ISO-CUBE web-shop and tutorials at:

Meet the ISO-CUBE. This 3D drawing tool has been meticulously designed and developed to enable anybody to create astonishing 3D isometric drawings in minutes, and excitingly, you are now able to back it on Kickstarter.

By using the ISO-CUBE and the ‘Drawing-Block’ method, you can build up an isometric shell, which you can then ‘sculpt’ using ‘isometric addition and subtraction’ techniques. This aid makes light work of what can be difficult for the most experienced of designers – making 2D drawings look truly 3-Dimensional.

Neal Turner (Machine Realm and full-time Teacher) and Joseph Birks (MD, Mindsets) have had a longstanding relationship. Neal has a great eye for detail – he’s gone to Joseph a few times in the past with amazing designs and kits. But nothing had piqued Joseph’s interest more than the simplistic beauty of the ISO-CUBE. Being a teacher, Neal originally designed the ISO-CUBE to be more cost-effective and simpler to use than other drawing stencils on the market. Joseph wanted to help Neal get the ISO-CUBE ‘out-there’ – so what better place than Kickstarter.

Although originally designed for assisting the teaching of 3D design and isometric drawing (GCSE and A-Level), the ISO-CUBE is for anyone and everyone. Whether you are creative or not, the ISO-CUBE helps you to unlock your potential.
