I found this cat really helped with the programming 


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 50%

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

50% Scale of original Flitetest design. EPS foam
AUW Weight 120 Grams

She needs to lose her puppy fat and slim down to 100 Grams
2900kv C10 motor from HK with a 4.1 X 4.1 prop witha  3 cell draws it 5.4 Amps on the test rig for 123 Grams of thrust or 4.4 Oz

The weight can come down with a 3C 180mAh NanoTech 
19 Grams vs 32 Grams for the Zippy above

Found out why the maiden flight ended with Issac Newton attacking my plane. The pilot said it seemed to loose power as she turned into the wind, and he was flat out for whole flight due to the excessive weight of all that Corriboard, I have a lighter air frame in the works 1300 Grams wing loading 12.53 oz/ft², 250 Watts per Kilo Please see the spreadsheet. I think its highly likely she just ran out of juice?

This is why I suspect the battery state

Turnigy Accucel-6 50W 6A Balancer/Charger

Input Voltage: 11~17v
Circuit power: Max Charge: 50W / Max Discharge: 5W
Charge Current Range: .1~6.0A
Ni-MH/NiCd cells: 1~15
Li-ion/Poly cells: 1~6
Pb battery voltage: 2~20v

Some how or other my charger was set to a max CAPA of 200mAh so my batteries were never charged. My wife helpfully pointed out that I should have read the manual (Here is the manual) but that just isn't the bloke way, why do girls not get that?

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.

On 14.8 Volts its pushing almost 500 Grams, not so bad thrust mapping is as follows.

156 Grams 3.0 A 42.9 Watts
197 Grams 3.9 A 55.1 Watts
257 Grams 5.5 A 76.0 Watts
296 Grams 6.7 A 90.9 Watts
