Electric skateboard?

By , September 18, 2011 9:42 pm

Like you probably know, I was doing a intern this summer. My good friend Rudy, did a intern at this place where they play with electric vehicle and other cool stuff.  Toward the end of his intern he told me that the company was moving so there where throwing stuff out. He send me pictures of what they where getting rid of! After seen the picture I had a OMG face! He told me that he will give me those things if I would trade something. That something is a video of school projet he did back in 2009. He build a musical Tesla coil and we had 4 feet long fluorescent lamp on the desk, connected to nothing, that was lighting up. So yes we did trade and I got what I wanted!

Here it is:

electric skate board

Yes I also got this ZAP electric belt driven scooter. It has inflatable wheels.

electric skateboard motor system

Like you probably imagine, I already started to make it apart.

It is in a very good shape. The problem is, the remote control. It use a wireless remote control! I don’t have it and Rudy was not able to find it.  No a problem right. I did try some reverse engineering to see if I could directly send signal to the motor controller. Not really. The controller does not receive a simple analog signal. I took the controller apart and saw a microcontroller under the thick black epoxy. I guest it receive serial data from the RF receiver. OR it’s simply broken!
My first idea is to design and build my own electronics using a Wii remote control! It’s a DC motor, should not be that hard!

After some searching, there is a couple of skateboard company

Got a helmet!

By , September 13, 2011 7:22 am

Today is my birthday and I got a super cool helmet from my girlfriend! She loves what I do but wants me to ride safe! :P

helmet for head trauma

I don’t know if you guys recall hackaday post entitle “1480W scooter motor guarantees head trauma“?  There was a pretty intense debate on helmet use! 79 comments in total! Charles from MIT also had is word on the use of helmet. He also has more crazy rolling device but does not wear a helmet.

I was able to stick my GoPRO on it. I had my GoPRO for more then 1 year now. Very useful and great video quality.  I do have a lot of videos of the scooter but did not edit them. Working on it. I am right now working on something else… look at the picture and tell me what you see…

Can you guest where is my last internship?

Here is a clue.

Yes, that’s me doing the robot in the middle!

Btw, my last internship day is friday!! After that it’s scooter and robot sumo time! I also have an important final years engineering project that has to be done before class start at the end of this month. Well, the project ends in December but we did I work hard this summer. There is one last important thing to be done. No worries, I will have tons of info coming in a few months.

The Voltitude bike

By , June 13, 2011 9:56 pm

I first saw this electric bike here.

What I love about this design is the way it folds up into this very small footprint. Have a look at the video:

It’s about 20kg (44pounds) and the max speed is 25kph (16mph).

I like the very simple graphic interface.

There website is here: http://www.voltitude.com/ and they have this neat video in french: http://www.voltitude.com/news/voltitude-on-swiss-national-tv.html
They say, they spend a lot of personal money on the project.  They have 800 pre-order and the Chinese are interested!

In the video they talk about the price and it should be between 4000 to 5000 Swiss Franc (CHF) so that is $4782 to $5980 US.

Flying quadracopter PCB

By , June 1, 2011 6:42 pm

I am 100% you saw this in the news a couples of weeks ago.

crazyflies_quadracopter_flying_robot

I was blown away by the design until I read a comment that linked to this:

 

nconev2_quadracopter_flying_robot

This is NC one V2

In my personal opinion, I think that the bolt holding the motor should be replace by something else. There is 4 of them, it’s heavy! When I worked in Hong Kong, on RC toys helicopters they use to remove every single grams of weight they could! 1 grams can change everything on very small craft like this one. I would of tried a press fit plastic adapter. The plastic adapter clips in the PCB and the motors is the press fit.

Look at that sexy components layout! Very well done!

NC one v2 getting cut in CNCThey get a normal squared PCB and they cut with the CNC.

 

Here is NC one v1

Very small!

You can visit there website here : http://www.nanokopter.at/tiki_v6/ ( in German). They are working on V3! It should be ready this summer… June 2011.

Here is the link of the first quadracopter: http://www.daedalus.nu/category/crazycopter/

If you like flying things, check this other amazing German builder: http://www.smartflyer.de/index.html (In German) He has been building quadracopter for years!

Smart Flyer III

If you know about other small quadracopter, please leave a comment!
