  • ** NEW ** Fusion Control Centre's Accelerometer Version 2

    This is the first in a new line of sensors that is supposed to be easier to use, more accurate, and more intuitive.

    This accelerometer has slightly better accuracy than the current accelerometer but has a couple extra things that make it tremendously easier to use. One of the big things is that instead of jumpers to select the gain it is a simple slider switch. And ontop of that, when you slide it to an option a little LED lights up to let you know that setting is registered. The +X and +Y directions are printed on the board to make figuring out what axis it is on much easier. (+Z is directly out of the board). There will be (not tested yet) an auto-calibrate function that will help make each sensor as accurate as possible. After soldering and shipping and being manhandled the pressures may be different than when I calibrate them. By laying it on a relatively flat surface face up and pressing the button, it will auto-calibrate within a few seconds. That simple. Another little extra help is the labeling of the Fusion Brain sensor connections. It labels the positive, ground, and sensor output connector. It also labels which port is X, Y, and Z. This sensor can switch between +/- 6G or +/- 1.5G. If you never expect more than 1.5G, then you will get a better accuracy over that range by leaving it in 1.5G mode. For full scale, leave it in +/- 6G mode.


    Some handy dandy pictures:

    Kinda obvious from the screenshot, but this sensor will only work with the v6 correct?

      It requires 3.3v power. It might be able to handle 4.5v to 5v, but you will be toasting it. I am working on a little adapter board that will convert the 5v of the FBv3 and FBv4 into 3.3v compatible signals. However, this will reduce accuracy/sensitivity of that channel of the FBv3 or FBv6 since it will still have to work over the 0-5v range, but now the incoming signal is 0-3.3v.

      Having said that though, the FBv3 is way unsupported, and there is enough existing sensor stock to carry forwards for the FBv4.

          Measuring G forces is the only useful thing it does

          In a car this is very useful for lots of reasons. The primary reason being if you ever take your car to the track or just like to pretend you do Many new cars are equipped with G-Sensors to show lateral acceleration through the turns (how much grip do you really have before your tires float and the back end flies around?). Acceleration forwards is good for measuring your cars actual acceleration curve (it can actually detect the moment VTEC kicks in) and also for seeing how good your brakes are.

          I used it in one vehicle to measure the braking pedal force versus actual braking. There were 2 braking systems per wheel and then the parking brake and a backup brake. The 2 main systems have a few millisecond gap between them when transitioning that some people can feel. Of course when humans "feel" something it is much worse than it is. So gathering empirical data to show it was milliseconds, not seconds was important.

          Outside of the car there are lots of options too.

            So when would this be available for purchase?

              I am hoping in 2 to 3 weeks. My manufacturer has had some delays as usual including the month long Spring Festival. :/

              The same time the relay boards (mega and mini), volume control, itty bitty brain, this, and a few more goodies for testing arrive.

                I wouldn't mind one of these in my car too . My problem is likely to be making an appropriate display embedded into RideRunner - but I'll give it a go! .
