Good deals (hopefully) from China

After weeks of pure software programming I am looking forward to doing some hands on.
I have an Arduino Uno at home and yesterday I went online to get a motor shield and 4 motors to make a quadcopter. However each motor itself was $30 and so I decided to start on a cheaper project instead. I ended up ordering some items from the website DealExtreme.


Here is what I bought. The prices are in USD:

HC-SR04 Ultrasonic Sensor Distance Measuring Module-133696				4	US$ 9.96
UNO R3 Development Board Microcontroller MEGA328P ATMEGA16U2 Compat for Arduino - Blue + Black-215600				1	US$ 12.23
USB-AV USB Power Current Voltage Tester - Translucent Blue + Silver -235090				1	US$ 4.44
170 Points Mini Breadboard for Arduino Proto Shield (Works with Official Arduino Boards / 6 PCS)-148870				1	US$ 5.42

And here is the price of the items or original (if available) items in Singapore:

Ultrasonic Sensor                              :S$58.50    <SGbotics>

Arduino Uno R3                               :S$32.70    <SGbotics>

170 Points Mini Breadboard (1 Piece) :S$2.90      <SGbotics>

USB Power Curent Voltage Tester      :S$15.90    <Qoo10>

While the items are cheaper, you have to remember they are clones. For the Arduino Uno clone and the Ultrasonic sensor clone I would run some tests and post their results once I get them on hand.

As for the USB Current/Voltage reader, I spent 2 hours on Sunday hunting in Sim Lim Square and Sim Lim Tower for it but could not find it. So am quite happy to get it at that price. 

If the Arduino clone works without issues it will definitely be the board being tested on in the future, especially if flight is involved.
