On Your Phone While Driving an Electric Skateboard

Skateboards are fun, but you have to do all that pesky kicking in order to get anywhere. That’s why [Nick] decided to build his own electric skateboard. Not only is the skateboard powered with an electric motor, but the whole thing can be controlled from a smart phone.
[Nick] started out with a long board deck that he had made years ago. After cleaning it up and re-finishing it, the board was ready for some wheels. [Nick] used a kit he found online that came with the trucks, wheels, and a belt. The trucks have a motor mount welded in place already. [Nick] used a Turnigy SK3 192KV electric motor to drive the wheels. He also used a Turnigy electronic speed controller to make sure he could vary the speed of the board while riding.
Next [Nick] needed some interface between a smart phone and the motor controller. He chose to use an Arduino Nano hooked up to a Bluetooth module. The Nano was able to directly drive the motor controller, and the Bluetooth module made it easy to sync up to a mobile phone. The Android app was written using MIT’s App Inventor software. It allows for basic control over the motor speed so you can cruise in style. Check out the video below for a slide show and some demonstration clips.
It’s a popular project, and eerily similar to the one we saw a couple months back.

Baby Fogey flew on a rare calm day she's a bit to heavy with a 2 cell 500mAh nice wee plane will take her to the indoor flying club another time once I have reduced the mass so its not so fast. Here ars some more 50% Fogey's Indoor Micro Old Fogey

Maiden flight of Yellow Plane flown by a local pilot Richard to avoid instant crash I would cause. A little tail heavy but flew pretty well on a gusty day, I'm told control was good. Ended in a crash but not too badly damaged, learned a lot. I'm just chuffed if flew looks pretty good on such a windy, which is pretty standard for the south island this time of year.
My scratch built FPV platform. Took around 30 hours to build mostly Corriboard with some ply, aluminium and carbon fiber spars. Total material cost around 50 US$. Got a DT700 (see tests data here) which hopefully will be an adequate power source. Its a modular design based around an armature, so wings and tail etc are bolted on and can be exchanged for testing parts and ideas. Have a pair of KM3 wings and the Corriboard ones shown below.

Based around a stiff wooden armature and two aluminium tail spars the wings are removable for transportation. According to my calculations the wing loading is 15.5 Oz/Ft² at a flight weight of 1700 Grams. A glass fiber nose has been molded and is curing now which is around 80 grams, which will contain the FPV gear and the main battery.
