Goodwood Mind Controlled Scalextric (Showcase Project!)

Commissioned by Solar Flare Studios, I was technical lead and developer for this Mind controlled Scalextric track at the Goodwood Festival of Speed 2021

Yes! The public could use mind reading headsets to control the cars!

Using Emotiv Brainwear technology, in under 8 weeks, I had to design and create the hardware and software solution to use these headsets to control real life Scalextric slot cars!

I had to determine how to control the cars via digital signals and establish how best to use the Emotive headsets to enable slot car racing controlled by the mind!
This entailed me building a Raspberry Pi micro-processor circuit to control the motor speeds using PWM and then building a framework so that I could determine the Emotive headset API data and respond accordingly.


“…The software itself merits further attention. ‘I had about seven weeks to make it,’ explained Sheehan…”

It was great that The Register Magazine gave an excellent write up!

It was interesting working with this latest generation of brainwear technology; I experimented with all sorts of different triggers before settling upon an easy task for the general public to achieve – focusing on a small dot!

After a few practice goes looking at a dot on a screen which gives you immediate feedback on how well you’re focussing by growing smaller or larger, it soon becomes easy for most people to achieve on demand and can thereby control the cars going around the track!

I used Unity3D for the visuals for the active table display and enrolling calibration process, and Raspberry Pi with Python with some electronics to control the motor power for the cars.
I had some support from Grigor for the emotiv api handshake and some comms.

… I soon realised I was going to have to make the speed control more subtle …

Here it is in use.

    Working with Copperdollar, over 12,000 people pass through our coffin doors every season! Lots of fun Kinect VJ’ing and watching and learning from people interact with my installations.

    Raspberry Pi

    I use the excellent Raspberry Pi when I need a powerful compact computer.Programming in Python, I often hook these up to my own projection mapping software and adhoc mobile phone controls.

    Interactive Table

    Utilising the very capable 7th Sense projection mapping software, I created a Unity3D app using a Kinect 3D sensor to make an interactive table for the Diageo international drinks company. The interactive table worked in conjunction with lighting and multiple projections so that the users could use it to tell a story.

    An installation at The Lab at Shell Eco-marathon Manila & Detroit 2015, with Imagination. Using 5 Microsoft Kinect sensors, this large scale interactive exhibit allowed the participants to play and experiment with different energy types. Programmed in Unity3D.


    With Inition, I made software to read RFID tags in objects which the users could reposition.Positioning these objects would further a displayed story.C#, Unity3D

    Creatures – consequences

    I created a browser friendly Unity3D app which allowed users to construct their own creatures from different segments.

    Escape Rooms and Paradox Place

    A wrote an escape game galled ‘Strootak’ which was a version of the psychological game in which you are presented with a word spelling a colour, but the colour of the text itself is a different colour… You work against the clock to press the button which matches the colour of the text.. It’s harder Escape Rooms and Paradox Place
