We’ll start the show off in earnest on Monday, with an episode looking at Maker’s Row, an online marketplace where businesses can find US manufacturers. Keep coming back every Monday and you’ll find episodes looking at FlyCleaners, HowAboutWe, Gotham Greens, Wool & Prince, Atavist, and others.

Oh, and if you’re wondering why we neglected the rest of New York, hey, we like those startups too. We just didn’t want this to get too broad — and Built In New York doesn’t have the same ring to it. rc toys
How an rc airplane moves and turns
Discussion / Posted by zae / 10-29-2014 @ 02:34 AM / 64 Views / 0 Comments / Reply
So now you know that radio signals are sent to the airplane when you operate the transmitter, but why does the model do what it does when you move the sticks?

All controllable airplanes have control surfaces which are attached to their parent flying surface and different control surfaces have different purposes. The primary control surfaces are rudder, elevator and ailerons.

The most basic rc airplanes will only have rudder control; the rudder is the moveable hinged section of the vertical stabiliser, or fin, at the rear end of the airplane. It controls the left/right directional movement of the airplane, or yaw; when the rudder deflects left the plane turns to the left and when the rudder deflects right the plane turns to the right.

Technology has the potential to make our lives a lot more pleasant. But have you ever considered all the ways it can be used to make them scarier?

Imagine a Jack-O-Lantern that senses when guests are near before going into scare-mode. A skull that shares secrets from the afterlife. A fully interactive laser maze. All these are possible with the Arduino, a tiny microcontroller perfect for DIY projects. rc
The social media company
Discussion / Posted by zae / 10-27-2014 @ 04:30 AM / 101 Views / 0 Comments / Reply
The social media company is increasingly becoming to the news business what Amazon is to book publishing — a behemoth that provides access to hundreds of millions of consumers and wields enormous power. About 30 percent of adults in the United States get their news on Facebook, according to a study from the Pew Research Center. The fortunes of a news site, in short, can rise or fall depending on how it performs in Facebook’s News Feed. rc wonderfullness

iPhone 6 and 6 Plus are selling like crazy
Discussion / Posted by zae / 10-22-2014 @ 04:19 AM / 237 Views / 0 Comments / Reply
Apple's latest quarter included only about a week of iPhone 6 and 6 Plus sales, but the devices already gave the company a boost. Apple sold 39.3 million iPhones in the most recent period, up 16 percent from the year-ago period. Analysts, on average, had expected Apple to sell 37.8 million iPhones, according to a poll by Fortune. The company's newest devices -- the 4.7-inch iPhone 6 and the 5.5-inch iPhone 6 Plus -- went on sale September 19, so Apple will get an even bigger boost from the products in the December quarter rc .

Part of the Sofar ethos is attention. At the Karen O show, Christine Cook, Sofar’s New York director, explained the rules: no talking, texting or selfies are allowed during the music, though people are encouraged to promote the event on social media during breaks. Audiences are also asked to stay for the whole evening, rather than arriving just in time for the headliner (one reason that Sofar doesn’t list its lineup in advance).rc online shop

Consider taking a class in basic car care or auto repair. You don’t need to become a grease monkey to keep your car forever, but if you know how your car works, you’ll have an easier time identifying trouble and you’re less likely to get ripped off by an unscrupulous mechanic. Women, especially, are at risk for being ripped off by mechanics. Knowledge is power!

Fly foam EDF

As previously mentioned, Ready To Fly foam EDF jets have really taken hold in recent times and the number of good quality RTF EDFs available has increased dramatically, to the point where it's as common to see such a jet on the flying field as it is a plane or rc helicopter - that wasn't the case a few years ago when rc jets were very specialised models.
One nice example of an entry level foam EDF is the original ParkZone Habu EDF which has since been replaced with the newer fibreglass version pictured:

While a Piper Cub makes an excellent scale trainer, a warbird like a P-51 Mustang or Corsair generally doesn't and is better suited to a 2nd or 3rd model after you've gained some experience. The faster flying speeds and lower stability of rc warbirds make them more exciting in the air, but more of a handful for a beginner to the hobby.
Having said that though, one exception to that rule is Hanger 9's PTS Advance Trainer Mustang.
The primary RC airplane controls
Discussion / Posted by zae / 10-08-2014 @ 03:43 AM / 584 Views / 0 Comments / Reply
Getting a firm understanding of rc airplane controls - what they are and how they work - will help you get much more out of your new hobby and you'll become a better rc pilot for it.

The number of controls necessary or required differs between planes; the simplest rc airplanes will have just one single control while the more complex planes may have five, six or more. Your 'average' rc plane will have three or four controls, this is by far the most common number.

13 Attachment(s) Feetech T-SCServo 15kg Smart Control Servo Controlled By Arduino
New Product / Posted by Strongwind / 06-04-2014 @ 01:48 AM / 6,052 Views / 1 Comments / Reply
Feetech RC T-SCServo 15kg Smart Control Servo ( Controlled By Arduino)

FT-SCServo is meaning that Smart Control Servo was R&D and manufactured by FEETECH.

SCServo can work at servo mode and wheel mode.

The servo mode can be used to multi-joints robot since the robots can be controlled with specific angles. (The factory default setting is servo mode)
The wheel mode can be used to wheel-type operation robots since motors of the robots spin infinitely. (If wheel mode is available you need to program the value of position limitation the both are 0.)

If you want to reprogram servo, you need to download the PC software (SCServo_Debug), and to connect SCPC-2(Serial Control Programming Card) between servo and PC.

More about SCServo_Debug and SCPC-2 introduce please reference its instructions.

SCServo has a unique ID number to identify on BUS network.

The range from 0 to 253 (0xFD) can be used (The factory default setting is ID 1), and, especially, 254(0xFE) is used as the Broadcast ID. If the Broadcast ID is used to transmit Instruction Packet, we can command to all SCServo.

After programmed servo ID, to be best way is written it on the sticker of servo. If not, maybe you will forget the ID when you programmed many servos.
SCServo have kinds of baud rate available.

The baud rate from 38400 bps to 1M bps can be used.
They are 38400, 57600,76800,115200,128000,250000,500000,1000000. (The factory default setting is 1000000 bps)

SCServo can feedback the value of Position, Temperature, Load, Speed and Input Voltage.

Also we can reprogram the speed of rotation, the max output torque, operating voltage limit, and operating temperature limit etc.

SCServo is easy to be controlled by Arduino.

SCServo needs to have a TTLinker connect to between Arduino and SCServo.
If not please reference Connection to UART.

TTLinker is a signal conversion board. Arduino needs to convert its UART signals to the half duplex type and through TTLinker connect to SCServo. Also TTLinker have more interface used to kinds of sensor and compatible with Arduino.

Arduino library SCServo

We have SCServo library to be used when you are using Arduino to control SCServo. You can download it from website of feetechrc.com.

For example Arduino code as shown below.
#include <SCServo.h>
void setup()
Serial.begin(1000000);//init Serial baudrate
void loop()
u16 i;
for(i = 0;i < 1024; i++)
SERVO.WritePos(0xfe,i,100);//All Servo(broadcast) rotate to the position:i
for(i = 1024; i > 0; i–)
SERVO.WritePos(0xfe,i,100);//All Servo(broadcast) rotate to the position:i
This is show that using broadcast instruction to control all of SCServo on the BUS.
About instruction of WritePos, RegWritePos, ReadPos, RegWrite, Action, SyncWritePos and more introduce instruction please reference its instructions on website of feetechrc.com.

Half Duplex Asynchronous Communication

Half duplex UART is a serial communication protocol where both TxD and RxD can’t be used at the same time. This method is generally used when many devices need to be connected to a single bus. Since more than one device is connected to the same bus, all the other devices need to be in input mode while one device is transmitting.

The Main Controller that controllers of the SCServo actuators sets the communication direction to input mode, and only when it is transmitting an Instruction Packet, it changes the direction to output mode.

Connection to UART
To control the SCServo actuators, the main controller needs to convert its UART signals to the half duplex type. The recommended circuit diagram for this is shown below.
