Virtual reality has come a long way but some senses are still neglected. Until Smell-O-Vision happens, the next step might be feeling the wind in your hair. Perhaps dad racing a sportbike or kids giggling on a rollercoaster. Not as hard to build as you might think, you probably have the parts already.
Off-the-shelf devices serve up the seeing and hearing part of your imaginary environment, but they stop there. [Jared] wanted to take the immersion farther by being able to feel the speed, which meant building his own high power wind generator and tying it into the VR system. The failed crowdfunding effort of the “Petal” meant that something new would have to be constructed. Obviously, to move air without actually going on a rollercoaster requires a motor controller and some fans. Powerful fans.
A proponent of going big or going home, [Jared] picked up a pair of fans and modified them so heavily that they will launch themselves off of the table if not anchored down. Who overdrives fans so hard they need custom heatsinks for the motors? He does. He admits he went overboard and sensibly way overbudget for most people but he built it for himself and does not care.

A rollercoaster company in Germany called Mack Rides joined forces with a team of virtual reality developers in the spring of 2014 to create an experience like no other.
The idea came from [Thomas], a professor at the University of Applied Sciences Kaiserslautern who was working in the department of Virtual Design at the time. The thought of extending a real rollercoaster ride with an Oculus Rift was an intriguing one, so he approached Mack Rides with the experiment, and the ground-breaking research began.
Hundreds of tests were done over the following weeks and months, which provided insight into how we perceive time and space while inside VR. This led to some interesting discoveries. For one, the VR track inside the Rift could be more complex than the real one. This meant that the directions could be contorted into different angles without the user feeling much of a difference. Knowing this, the developers were able to unfold/extend the track well beyond what was possible in real life.
Another epiphany had to do with the rails, which actually didn’t have to be present in VR at all. In fact, it was better if the tracks weren’t there because the experience was much more exciting not knowing which way the ride was suddenly going to take. This made things exponentially more surprising and compelling.
By far the most startling revelation was the reduction in dizziness and motion sickness during the tests. This was attributed to the complex synchronization that the mind goes through when melding together g-forces and the actual rollercoaster rides with the virtual ones displayed inside the Oculus Rift.

This week we have been in touch with [Will Pemble], Geek Dad. After a visit to Magic Mountain in early 2013, his son [Lyle] asked “Why don’t we build our own rollercoaster, Dad?”. [Will] couldn’t think of a single reason why not. This was the start of the CoasterDad Project. Excited by the challenge of building a Backyard Roller Coaster, [Will] also thought it would be a fantastic opportunity to teach [Lyle] about physics. Family, Fun, and Physics – what could be better?
The track is made from parallel PVC pipes on a lumber frame, similar to the one we saw for the Manpowered PVC rollercoaster, but it is more varied and looks a lot sturdier. [Will] is now working on mark II of the cart made from a steel frame with skateboard wheels and has independent axles. He is planning to add a pedal mechanism with freewheel, so you can get a little extra oomph on the rises.
In [Will’s] great videos you can get a front row seat on the coaster and see that even though it is fairly compact it has enough rises, troughs and turns to keep you entertained. It may not be quite as exciting as [Jon Iver’s] homemade rollercoaster, but when finished, the rider will be able go round and round self-propelled to their heart’s content, or till they puke, whichever comes first. [Will] also explains the theory and practicalities behind making a strong, safe, but really fun coaster. Don’t miss the videos after the fold.
Have you made a backyard roller coaster, or are thinking about building one? Have you got any questions about [Will’s] roller coaster build? He’s up for making a video to answer some of them, so please leave questions for him in the comments below. We will post the video later on.
