skateboard
So, this is my self-balancing one-wheeled skateboard. I got inspired to create this after seeing Ben Smither’s video and documentation of his. Anyhow, if you haven’t seen it take a look at http://ben.jellybaby.net. I obviously modeled mine largely after Ben’s design. Rodger Cleye is also in the process of creating one at http://electricunicycle.com
The basics are
- controller - arduino, actually its a barebones from ModernDevice
- motor control - osmc
- motor - 350w electric scooter motor - chinese
- tire/wheel - 11×7.1×5
- batteries - 2 @ 12v x 7.5Ah AGM’s
- imu - sparkfun 2 degees of freedom
- pulleys - from https://sdp-si.com/eStore/
- weight - approx 35 pounds

oh yeah, your board is sweet!

What about using the 24 Volt 300 Watt Kollmorgan® Brushless Motor With Built In Speed Controller from electricscooterparts.com? It has a built in speed controller. I’m pretty new to using the arduino ….

Jeez, this owns a Segway any day. To think that people thought that was cool.

Hey can you put the code back up or email it to me. I am very interested in building one of these my self and would love to look over it thanks.

Hi,
sounds like a great project and looks good!
Is the programm for the arduino controller open source? Would you publish it here or send it by eMail?
One question about the batteries:
how long (how many minutes) does one batterie-load least?
Did you measure the Amps (duration and peak)?
Thanks a lot and hang on

dude, that board rocks, if you don’t make any money off your hammer control scheme, kids would love that for christmas. Now you need to build a little kicker jump.
thanks for the information on the hammer, I called you when you were still in marketing phase and info was confidential, I will be using your ideas to build my hammer, there’s nothing wrong with recieving fruits for your labor, we all have mouths to feed. thanks again and keep the inventions coming.

I think it’s one of the best Arduino projects I’ve seen. Is it possible to take a look at the pde sourcecode?
Tnx and… My compliments!

Hey Chris,
I finally got mine going. I was distracted with holiday robots! Anyway, if you want to see Leviskate footage, check out the video under the leviskate section of www.electricunicycle.com. How is yours doing? Are you still playing with it? Did you add any enhancements? Hope you are having fun. Keep up the good work. — Rodger

Awesome! Any chance you could share the processing code with us/me? I’m skateboarding myself and just started using arduino. It would be really cool to build something myself from this

So for those of you asking for the code… for good reasons, I will refrain from distribution. If you would like to discuss coding of this sort and are already on your way to something that is usable/complete, I’m happy to talk. You send me yours…

Hey, I actually just finished the mechanical side of my one wheeled skateboard… and have some nice little features in mine. for example i have a small momentary switch which controls the entire power on and off of the board rather than a big mechanical switch. when the momentary switch is pressed a relay is flipped which allows power to flow to the motor controller. the arduino is always on in a standy-by mode just waiting for someone to click the momentary switch…
i’ve written all the nice code which makes my relay flip and all the subroutines with the stand-by mode and such but i havent a clue where to start with the balancing subroutine and my research has not helped me at all! COULD YOU PLEAAAAASSSE HELP ME!!!!!!

I was wondering why you used the OSMC instead of something a bit cheaper? I am planning out one of these and I am trying to make it as affordable as possible. I was looking at the Simple H controller which is http://robotpower.com/products/simple-h_info.html . Is there any reason this would be harder to use? Or not able to use it at all?
Thanks.

I actually tried a simple-h to start with but couldn’t get it to work well. Not sure why. I futzed with it for quite awhile and then finally gave up and went to the osmc, which got me going within minutes of hooking it up. sometimes paying for the good stuff upfront actually does end up saving a lot in the end. good luck.

Hi Chris, I’m from Italy and I’m trying to build an electric skate like yours, but I need some help (I promise, I’ll not ask you the code
).. could you contact me by email?
Hope to hear from you soon, thank you

I was wondering if you had to adjust the frequency of the PWM signal from the arduino to the OSMC. OSMC is spec’d to take 2, 4, 8, 16, or 32 kHz, but the arduino analogWrite() function outputs at around 500 Hz. How did you do your PWM?
By stephen on Nov 23, 2008
7 months later and I’m finishing up on the program. I’ve got the frame, mechanical, and electrical all in place but my program is glitchy. It doesn’t respond very fast and when it finally does it doesn’t give enough power to the OSMC to make a difference. I’ve given the OSMC the same amount of power as my Arduino’s only command (without the entire balancing program) and it’s a whole lot more powerful.
I’m thinking that I made it too basic to control the board. I’m only using the accelerometer because it hasn’t given me any bad values even when I’m shaking the heck out of it. If you’d be willing, could you take a look at my program? My email is ehm724 [at] yahoo [dot] com.
