  • Good lamp week led

    posted by karlos1962

    Cheap and useful desktop led lamp
    Great you can use 3x AA or directly connect to USB
    Small size but not tiny
    Lightweight... you can even use it as a flashlight
    Price is not really the best for the quality but still not bad deal
    If you need a desktop led lamp with a good (not best) price and something that you can change the leds in case of need, buy this one and you wont regret.
  • LM317 Regulator Module from DX is Great

    posted by bdabill

    The circuit used in this LM317 regulator module is standard and the LM317 device is almost indestructible even when abused.The module is beautifully assembled on a very neat, labelled PCB with well-soldered joints.A small heatsink is fitted to the LM317.A diode bridge is fitted at the input so reverse polarity connection is catered for and an a.c. input can be used.The module uses a linear circuit (not switched-mode) with no inductors so is easy to understand and repair if needed in the future.Very good value for money.Delivery and service was great from DX dealextreme and UK Post Office.
    I will buy from DX again in the future.
    Very good value for money if it fits your needs.
  • Mobile power suppply

    posted by Koppen24

    Handy device, easily and accurately set. I use it in my car for media player. with 4 diodes I have the input voltage 2.5 volts lowered, then I could adjust the tension nicely at 12.5 volts. because a car when the engine is running 14.5 volts charging. The media player works well and without fault in sound or image
    the device is recommended for anyone with a laptop on the go with the car.
    Handy device for little money, certainly useful for a laptop because they are generally at a higher working voltage than 14.5 volts in a car.
  • Very good regulator

    posted by Bunny1

    Simple and robust, very usefull. You can change trimpot by fixed resistor, there are pads to do it, and it turns into a fixed voltage regulator. Overcurrent protection. Voltage adjustment is very precise.
    Small and simple, easy to fix, possible use in many experiments and prototypes. I saw some other regulators based in LM2596 more cheap, but using bobin wih low inductance, let to experience in future.
    If you need a regulator for experiments or low production electronics, use it.
  • Great little module with wide range of applications

    posted by Rhema1

    These are great voltage boosters with a good capacity. Versatile. Very smooth and stable output.
    I have a several of these units that I had purchased elsewhere for less. But delivery time was unpredictable. The price here being about $4.00 each higher. But wanted to test the delivery time and needed 3 more. So I purchased here.
    Shipping time was moderate. The device itself is great. I really like these little units.
