This video show that the controller working for the first time.    !!!!!Awesome!!!!!!

I could barely keep a wheelie up and going before I started using my controller.






Tuning the code a little more before the ride.                      >>>>>>>>>>>>>>>>>>>>>>>>







Ever since I was a kid I wanted to ride wheelies.  So I built a Arduino Wheelie Controller and started enjoying longer, safer wheelie'ing.  I use an Arduino Duemilanove ATMEGA 328 to control a LARGE  digital servo powered with a homemade servo power curcuit, coupled to a hydraulic hand brake.  The handbrake is connected to a steel braded brake line that runs down and connects in place of the rear hydraulic brake reservoir.  The controller uses a triple axis accelerometer and a single axis gyro to calculate when and how much brake to apply.  This controller can be used on 4wheelers and motorcycle with rear disc brakes. 


<<<<<<<<<< Controller

1.)Arduino Duellinove

2.) Triple axis accel & single axis gyro  "Black Box"

3.) Power supply for LARGE servo

4.) LARGE DIGITAL High speed & Torque servo w/ metal gears










  I connected my servo to a handbrake like this one and mounted it under the rear fender. >>>>>>>



I used this adapter to connect my handbrake to the rear brake master cyclinder.

  • I found the the code for the controller in an old email Sweet!  I knew I set that to my self :)..
  • I'm glad my dad sad NO now that i'm older.  I have lost friends, watched friends get hurt, and have some that are really mangled up for life because there dad's didn't say no.  Good job!

    My 29yr old son wants to buy a Ninja 'cuz I used to talk so fondly of my brother's MX ride, but I just told him last week that I am his dad & I can still say no!

    I have nightmares that he'll try half the $&@# I used to on our 250.

    The old "do as I say, not what I do" syndrome.
  • @ sqt Ric LOL nothings wrong, its cool whats funny are the bikes,  I'm 30 so not old & not a spring chicken  and yes it kinda hurts longer than it use to.  :)

    What's so funny about me riding MX in the '70s?
    Ya, they had invented the wheel by then!

    Not all of us are young whipper-snappers...
  • The trippy one that i realized in hs is the fact that the wheels are giant gyros and keep a bike very stable.
  • Correct TD

  • It is conservation of angular momentum - increasing the momentum of the wheels in the 'driving forward' direction while flying through the air would increase the momentum of the rest of the 4-wheeler in the opposite, pitch-up, direction, so that the momentum of the entire vehicle stays constant.  Applying the brake would have the opposite. pitch-down, effect.
  • @Sgt Ric: I think it has to do with the rotational energy stored in the tires. I don't think the air has anything to do with it. But if the tires are spinning and the brakes are hit wouldn't it put some torque on the vehicle pushing the nose down a bit? The set up is still necessary since these adjustments are just that. 



  • I have some friends that restore those bikes and turn them in to flat trackers.  Sqt Ric it's true though.  U should get out and do a little riding.     Since the 70's?  LOL
