  • A Basic IR Proximity Detector

    posted by DendoRacing

    Easy to interface to the Arduino. Adjustable sensitivity for each detector allows detection range to be adjusted between 2cm to 5cm. LED indicators on board display detection status which makes tuning and testing simple.
    I was able to use this to build an Arduino obstacle avoidance robot that worked very well in the right conditions.
    A basic four channel IR proximity detector that is suitable for indoor use only. If you need a more robust detector, look for something that uses modulated IR light to filter out other light sources.
  • Good deal!

    It works really nice, I didn't notice much of a difference between the official sony stick and this one.
    The red makes it really stand out. I'm currently doing a red and silver PSP and this makes it look nice.
    If you break your analogue stick and send the PSP to sony for repair, they'll charge you like $40 when it costs them about $5 and 5 mins work for some employee to open the PSP and install this, so you save a lot of money buying it from here.
    It would be nice if the sensitivity problem was fixed, though this not that bad.
    Buyers should note that the installation of this is not for beginners, you may break your PSP when installing this.
    Good value for the price, it makes your PSP look really snazzy along with red buttons.
  • Well worth the money

    Simply put, this gadget puts out a red laser beam. Brightness compares favorably to other lasers I own.
    Works fine on a 3v 2032 cell. Doesn't eat too much power. Doesn't get hot. I ordered 5, and all 5 worked (until over-volted one).
    A great bargain. A good product at a good price.
  • Bright LEDs

    posted by bradley90

    These are super bright RED LED modules. With only a 10 Watt dissipation, it is really easy to mount to a small heat sink with a small fan and not worry about over heating the modules. These modules would make fabulous emergency back lights. By keeping the amperage below 500ma, a smaller heat sink would be required and a simple constant current source could be constructed using a 78LM05 voltage regulator and one resistor. No fan would be required
    None - Just great LEDs
    Bottom line, for the money, these are awesome LEDs. They can be used in interesting DIY projects like LED communications or theme lighting.
  • Works well with 3.3V Arduino

    posted by steveo

    Works well on a 3.3V Arduino using SPI. u8glib supports this display using the U8GLIB_MINI12864 constructor. Cute little display, works well
    Datasheet is available here: http://x.openjumper.com/mini12864/
    Inexpensive 128 pixel x 64 pixel graphical LCD.
