Full Size Motion Seat

Finally... its been a long time coming but the firsts tests of my full size motion seat for racing simulators have been quite successful.

Its taken a long time to try out the various methods for positioning and motor control, along with coming up with a suitably strong design for the frame. The video below shows the movement in conjunction with Live for Speed using a updated custom outsim app that I wrote previously for my small scale test.  I'm holding the camera and driving so its not that easy to discern all the motion.

The seat is still not bolted to the frame securely but, I couldn't resist gingerly sitting down into it in order to turn a few laps in Live for Speed.  It's a great feeling as you accelerate off and the sit tips back, quite realistic.  What surprised me is how little actual movement is needed to create the feeling of motion.  The motion has quite decent resolution (you can see gear shifts tipping the seat in the video).

The platform design is very compact and is using Permanent magnet DC motors with hall effect position sensors. At the moment its hooked up to a 4 amp 24v power supply which seems to provide more than enough juice with my 13 stone frame sat in the seat ;-)
It needs a little extra bracing to stop some unwanted movement and a better seat that can be bolted down.  I hope to be able to produce a kit which will include the motion base pre-assembled and ready to go... so all the consumer does is bolt on the seat of their choice and race.

Bomboozle iPhone
Some of my ex-IOMO workmates have founded a studio working on casual games in flash and across other self-publishable platforms.  Check out, I've started work with them on a few projects.  One of which is an iPhone port of their popular flash game called Bomboozle, the original flash version of which can be found at

It's pretty close to being finished and our Apple App Store contact is inked, stay tuned for some screenshots and details of a release date.
