We can draw beautiful patterns with spirograph stims , and then paint your favorite colours.
Do you Know how to use Spirograph?Really?
What is a Spirograph?
A Spirograph is a curve formed by rolling a circle inside or outside of another circle. The pen is placed at any point on the rolling circle. If the radius of fixed circle is R, the radius of moving circle is r, and the offset of the pen point in the moving circle is O, then the equations of the resulting curve is defined by:
x = (R+r)*cos(t) - O*cos(((R+r)/r)*t) y = (R+r)*sin(t) - O*sin(((R+r)/r)*t) (moving circle outside the fixed circle)
x = (R-r)*cos(t) + O*cos(((R-r)/r)*t) y = (R-r)*sin(t) - O*sin(((R-r)/r)*t) (moving circle inside the fixed circle)
How to use it?
Here is how you can use the controls in this Spirograph applet:
· The first three scroll bars in the control panel let you change R, r and O respectively.
You can use the next three scroll bars to change the color of the drawing. These scroll bars change the red, green and blue values of the color (in the range 0-255) respectively.
· The last scroll bar lets you choose the number of iterations for the Spirograph. Move it to beginning and then slowly increase it to see how many iterations it takes to complete the spirograph.
· You can use the Random button to select random values for the radii and color.
This YiZhan I6s Quadcopter has no relationship with iphone 6s, it's a tiny hexacopter featuring a 2.0MP 720p camera, flip mode, 3 rates/spe...
PROS + Sporty, punchy + Wind resistant + Good radio range (>50m) + Good 720p camera + Jellofree plateform + 6min of flight time
CONS – No removable LiPo – 1.25mm miniJST battery connector with inverted polarities – No microSD card provided – YaP ?
It’s confirmed, the i6s is really fast !!! and the control range great too even without any antenna mod, you can expect to reach easily 50m. The flight time too, at good 6min that’s great.

A new way to capture the moment and the happiness around us.
A few things worth pointing out:
The i6s has an integrated camera, and it’s a 2 megapixel one at that! Given the price point and overall size of the aircraft this is pretty respectable. I’ll discuss the actual performance of the camera, along with sample footage, in the flight test portion of the review.
The battery uses a single cell 3.7 volt 450 mAh configuration, which is – strangely, considering the sizeable capacity – built-in. Also unfortunately, as a replaceable battery would – all other things being equal – have been preferable.
The LED lights are four in number (excluding the camera indicator and the purely aesthetical glowing “eyes” of the aircraft) and very bright. There is also color coding to help distinguish direction when flying. Just exemplary!

What kind of drone are you looking for?
These are the drones that most people are familiar with. Camera drones are usually ready-to-fly quadcopters that have stabilized cameras for shooting video and stills. The more popular reasons include exploring the world from new perspectives, experiencing what it’s like to fly, and capturing memories in a completely new way is a perfectly good reason for wanting a camera drone.
It's also one of the most gentle fliers that I've ever seen. Here is my new drone JYU Hornets S. * 120km/h high speed overflew the FERRARI racing supercar. * Dual GPS auto positioning system, the accurate positioning location, perfect advanced follower. * Intelligent battery could extend fly time for about 20 minutes, removable battery are easy for change. * Two antennas on the top of the transmitter to ensure a stable radio coverage. * Hovering point,Center surroundings, Hot follow performance is a great friend of photos and videos capturing.
