Motorized Joyrider

Nice indeed, I hope you have it fitted with airbags just in case something goes wrong, just kidding,

So what kind of motors are you using ? are they from electric window motors ?

About the software, is it simulator specific ? or does it detect joystick movement only ?

Looks like alot of fun, I am a Falcon and LOMAC fan my self, my favorite aircraft is the SU25 Frog foot, this type of motion system is perfect for that A10 and the aircraft I like.

To be honest, If I were to build this device, I would not use a projector but a big screen.

I am sure you have seen this before, but have a look at this device if you haven't already seen this vid on youtube.

I think when you sit in and use this device, you surely come out with a few bruises plus have a med kit handy.

Padraig-Airbags would be a nice touch. The motors are automobile windshield wiper motors that I tore out of cars in a junkyard. Considering how rusty and decrepit the cars looked, I was surprised all of the motors worked. The battery is an Exide Deep Cycle Marine Battery. The software is simulation specific and reads velocity changes. It does not follow stick movement. I believe that is why it looks laggy on the video.

Web,

Where did you get the 5 point harness? I'm looking for one for my fighter jet sim, and have been scouring ebay.

Thank you

This guy had a set of two belts for auction or sale on ebay. I e-mailed him to see if I could buy just one. By the time he got back to me, the auction was over but he told me he would sell me one at half the price that the two went for. I payed him through paypal and he UPS'd the belt to me:

This site gives you info about his company.

Good Luck,

Thanos-I e-mailed you but I'll tell you here as well..I redid the connection on the Basic Stamp and the "step in" utility worked fine. I did retain the angle change to 200 so it would bank to the left rather than the right. I will try the "neutral" utility the next time I fly and get blown up. Thanks so much.

Thanks for letting me know which motors you were using. Either way, you done a real fine job !

Hi All,

A quick clarification regarding the motion driver software.

The software reads flight data directly from F4's "shared memory" area. It normally uses aircraft acceleration data to generate force cues, however with the settings Web is using in the video the acceleration effects are almost completely removed and the driver output is programmed to follow aircraft pitch and roll angles directly and without any washout. The time delay between the roll / pitch motion occurring in the sim and the corresponding data output from the motion software is less than the processing loop time of the software which is roughly 50 ms.

Getting data out of the PC fast isn't too much of a problem - usually the tricky bit is getting the external hardware to react as quickly.

Nice video Web.

Thanks for making it clear, Ian.

Ian is right.

With proper external control hardware you can get motion response with no visible lag at all!!

See this video that I have made long time ago during the development of my new AVR electronics (AMC1.5):
