    Yes, they are still for sale and selling very well.

    I will contact the store to see if it is a simple clerical error. They are also available from MP3Car on Amazon:...

    Yes the FB is designed for automotive use. The inputs even though they only go from 0-5v on the FBv3 and FBv4 can read back (with big errors when Vadc > Vref) to 5.5v and it can survive with a...

    The appropriate headroom is actually 40V. That's the acceptable limit for a 12v system to ring up to in a car manufacturers world. And now with 48v systems starting to be developed the ring tolerance...

    I am here. :)

    The Fusion Brain was made at a time that Raspberry Pi and Arduino didn't exist. Out of good marketing and luck, they took off which is great for everyone. The point of the FB was an...

    Just an FYI, there is a firmware update available. This should fix any "bouncy" behaviour reported on some knobs. It should improve the finer movements on all of them.

    You can download it here for...

    With that sensor, it should work with almost anything since it is a driven output. A couple KOhms should be fine.

    Depends what sort of output impedance it has already. I usually recommend R values in the 1Kohm to 5Kohm range and those are easily found at Radioshack.

    If everything is working except 2 ports, that sounds like a hardware problem not a firmware problem. Reinstalling the firmware doesn't hurt, but probably won't help.

    If you just purchased it from me or MP3Car.com, we can swap it out if it has a bad port Dead On Arrival.

    Just a quick stupid question, but are you sure the red wire goes to the "+" marks on the analogue inputs?



    Can you add a generic voltage sensor and see what it looks like? If you add a voltage...

    Yes, AIN0 is the closest to the USB port.

    Quickest debug I can think of, have you been plugging it into the same port? FuseGL remembers what port you configure things to. What does the text file...

    Yes the inputs are 3.3v.

    And you won't get 3 equal signals on a 3-axis accelerometer when sitting there. You will get 1G in the Z direction and then hopefully 0G in the X and Y just from being...

    I'd love to help with that, but I have no idea. Hopefully this will bump it for someone else to find.

    How flexible is the PWM input the way you are doing it? The PWM value can be set between 0 (off) and 255 (full on, 100%). So if you set it to 100, you would get a 39.2% PWM.

    I can't comment on RRFusion, but there are quite a few active Fusion Brain users and new sales.

    What would you want to be illuminated? The shaft already has RGB glowing?
  18. Poll: Cool but really expensive! I actually never...

    Cool but really expensive!

    I actually never dreamed these volume knobs would be so popular. I am thinking of making a version 2. So far the ability to reprogram the functionality makes the list,...

    It should be possible. Right now I would have to do it custom for you and then using the bootloader you could modify it. But I might be able to make that configurable if I have some time to work on...

    My appendix exploded last month and I was in the hospital for a couple weeks and out of work for almost a month. I am still catching up on work-work, so this is on the backburner. Life just keeps...

    Very good idea. A substantial base to make sure it doesn't flop about.

    The question has been raised because these are selling like hotcakes, and I can't imagine that many are going for CarPC use....
  22. Poll: I think in your case, it would be best without a...

    I think in your case, it would be best without a case. The case would be more to make it a standalone knob. If you were going to mount and hide it with your own fittings, you would have to throw the...

    Does anybody have an interest for these to be enclosed in a plastic case. Something more professional and less hobbyist grade?

    It will be Class D if I design it. :)

    AB has its place, but in today's systems there is no advantage anymore. The silicon and designs used in the FETs of today are so far superior to what they...

    There are plans for a smaller, lower cost version. But I don't do small then work up. I do the best thing I could possibly think of, that nobody else has even come close to doing, then if there is...
