Cost: $800 | Time: 3 days
Power: The motor runs on 24 volts from two sealed lead-acid batteries, and drives the back wheels with a chain. Carnett plans to upgrade to polymer lithium-ion batteries to shave off about 12 of the board’s 60 pounds.
Going: The rider accelerates using a pistol-like trigger connected to a control box with a wire. The trigger and wire can be coiled and stowed when riding freewheel, so no electric parts get damaged or pose a danger in the event of a crash.
Stopping: To slow down, the rider squeezes a grip similar to a motorcycle brake held in the other hand, activating a rear-wheel disc brake that can stop the board far quicker than the regenerative-braking systems electric boards typically use.
The H2Whoa Credo: DIY can be dangerous.

Can you give full schematics for how to build this very cool board. If not, how can I get one?
I also want to build a board similar to this in the next few weeks and am looking for more details on exactly how the gear/sprocket was attached to the axle, how the motor was stabilized, what the underside of the back looks like, etc...thank you
[you may contact me via email]
In the video it looks like you're going really slowly. I skateboard and I'm fairly certain I can outpace you on a regular board, which weighs a five pounds as opposed to 60 and doesn't cost me money just to recharge. Who would actually spend $800 on this? Its a nice idea, but I don't really see a point in using it unless you're taking it uphill or something, in which case pedaling can get a little tiring.
Also, why did you choose to use an aluminum frame? Hmm, wood has that crutch of losing its better qualities after it gets wet. Maybe yours won't. I'm still shocked about the 60 pounds tho. That's not exactly something you can lift up pretty easily. Maybe come up with a design that weighs under 20 lbs and i'll look into it.
I am also interested in building this board. Can you email me further details?
I would like to build something similar to this, could you please e-mail me some more info on the control unit.
I saw your article in the magazine and thought this may be a good way to get around where I live without wasting alot of gas. I would like to build one for myself but the search for parts is becoming very difficult and I was wondering if you could tell me some places where you bought your parts and maybe tell me how to set up the back end of the board (wheels, brakes, trucks etc.). If you could email me a tutorial I would appreciate it. Thanks
I think i am on the same bandwagon as most of the people here and am looking for advice on where to start with the parts and the construction of the motor interface. I have lines on some of the parts but the actual connection to the rear truck is a little puzzling. Thanks.
Can you send me the entire schematics for this thing,it sounds awesome
I am like most of the commenters here, can you please email me the specs and the parts that were used?
Thanks
I would also like to know what motor and speed control components you used. Please email me, Thanks!
i really want to build a board just like this one, can you email me this stuff:
a: step-by-step tutorial
b: list of materials and tools
c: where i can buy everything i need
thanks!!!!!!!!!!
I was wondering if I could do the same for me I would really appreciate it
Thanks!!
This looks like a great project and I would like to build it with/for my son. Like many who have posted...it would be very helpful to get a list of parts and suppliers and some plans. Anything you have would be appreciated.
I would also like to build this skateboard! Please send me the instructions and parts list for building it.
Thank you!
I would also like to get the complete schematics, parts list, specs, etc.
I would also like to get ahold of the full schematics, parts list, and specs. Would you please email them to me. Thank you.
I would please like a parts list, specs, and full shematics for this. If you could please e-mail me that would be great.
Thank you very much.
I think this is a very interesting project but wish i could get full schematics and a parts list so i can create my own. I see that many other people are asking for the same thing so maybe you could add on to the article
all the components except the motor are pretty basic rc components, you can get a proper stock mountain board for about 300 buks, and you then just need a motor, esc, and controller.
I would also like to get ahold of the full schematics, parts list, and specs. Would you please email them to me. Thank you.
I am looking to make a carbon fiber board for the motor
$CAJUN$ can you email me schematics and maybe a parts list a walters.sk8r@gmail.com
I would also like to build something similar to this.
could you please email me a list of the parts, and a tutorial. thanks
whoa thats pretty sick I want know how to build one these if you could emial me all the tools and stuff I would need that would be so cool please
Wow, like most of the other posts im interested and could use some guidance could you email me schematics and where you purchased.
Thanks
I would like to build this as well I would like to see full schematics, and the parts list Would you please email them to me? Thank you.
hi can i get full schematics and part specifications
thx if not how i can i buy the skateoard or by the scheematic and stuff?
Hi there,
Can you please email me the details on how to build this projects?
Thanks.
Ken.
Hi there,
