  • low res heat producer :)

    The good news is that projector is cheap, lightweight and you can power it from a 12V battery or whatever, not just from a wall socket. Bad news is that screen resolution is about 320x240, not high as the specs say. The LED gets very hot in the is... Read more

  • useful helper tool

    posted bymlksa on 11/24/2013

    Good build quality. Quick lock and release. When you fold it - it's very compact. Good black finish quality. I bought it for about 3 times cheaper than our local stores offer. I'd like about twice as large arm. No other cons yet. Be careful when a... Read more

    posted bymlksa on 11/24/2013

    Good plastic quality. Buttons look like original ones. Lens shield is made from a coated glass. The hole against the USB plug lets you attach external display to the GoPro and the power source via USB. Back door lock is hard to open without a or a... Read more

  • good level indicator

    posted bymlksa on 03/10/2013

    It's a tiny PCB with separate input pin. You can show both AC and DC levels because there is a jumper that adds a short circuit to an electrolytic capacitor on input pin. The KA2284 IC has a built-in amplifier and rectifier, so you can make an as... Read more

  • simple and good charger

    posted bymlksa on 02/26/2013

    Good build quality. Doesn't overheat while charging. Uses an IC for AC/DC internal power supply. Cheap price. Large 18650 battery holder lets you insert protected cells as well. No EMI filter and no fuse in 220V circuit. A little bit high output I... Read more

  • a ready to use ammeter

    posted bymlksa on 02/25/2013

    It's an inexpensive analog current meter, doesn't need an extra shunt to work just because there is alrealy connected one under the back side cover. I't just a thick wire. I like the build quality and the look of the meter. It arrived exactly as a... Read more

  • good light for DIY projects

    posted bymlksa on 02/24/2013

    Slim and lightweight design, wide range of power supply voltage (all LEDs are connected by 3 in series, then grouped in parallel via 120 Ohm smd resistors). You can get some light even from a 9V source. Many spare connectors of different types I a... Read more

  • simple to use digital voltmeter

    posted bymlksa on 12/18/2012

    Compact size, no backlight required because of LEDs display, just two wires to connect (powered by the same battery you measure). Wide range of input voltage. Minimum input voltage is 3.2V which is too high because discharged Li-ion. batteries may... Read more

  • an useful thing for home lighting

    posted bymlksa on 12/18/2012

    This is a must when you have to double your light brightness without replacing a torch, without drilling, without using screws and a hammer. Just put this splitter instead of your bulb, then put two bulbs in it. Simple to disassemble if you use it... Read more

  • a good toy and musical instrument

    posted bymlksa on 12/18/2012

    You can play right out-of-the-box. Dual power supply (4xAA vs 6V DC). Compact and lightweight in folded state. Blue backlight of the LCD display lets you play in a weak ambient light. MIDI out (I didn't test it yet), headphone and speaker outputs... Read more
