  • Best power supply i could find for this low price

    posted by Rakkachi

    It is a small practical power supply unit, the connections are clearly marked out on the PCB. On one side there's the live/neutral input while on the other end there's the +/ground output. The solderwork on it is very good, not messy at all. The components used look solid and of medium to high quality.
    ideal for small projects that need a reliable power supply.
    small yet powerfull power supply unit.
  • Good one and perfect price

    posted by beemeeup

    With help of the very helpful Tipps in the DX Forum for this product it was very easy to set up and run it using the U8glib for Arduino.
    I will get another one on next order. Maybe I need to create a shield to make it even simplier to use.
    Easy to use product with perfect result for my needs.Good to handle with an Arduino UNO in SPI mode. This will save a lot of cables and it is still fast enough.I used PINs 10,11,13 to get it running. But I found no speed improvements using this hw MOSI Pins insted of Software SPI.
  • Really small!

    This is a really small switching power supply!!Line side has a varistor, thus some kind of surge suppression is provided.Output voltage: 5.10V (no load)When no load is attached, a witched power supply draws about NOTHING current. Ideal green replacement for those old bulky transformers.
    Still didn't measure ripple at maximum load (will put results soon), but according the specs it is around 150mV (according the specs it is 150 mW, but that is probabely a bug...)
    Nice, cheap and small switching power supply.Not worth making one youself......
  • Nice 5mW laser module

    posted by lanclan

    Very nice laser module for the price. Just apply 3VDC and away you go. I was able to get about 12mW-15mW of power out of it. Yes, unit has a IR filter.
    A more powerful laser module in this style would be nice. I recommend using 2 AAA or 2 AA batteries to power unit. Do Not exceed 3 VDC input.
    A nice start for those looking for a well priced laser module to experiment with.
  • Soundproof little circuitboard

    posted by Gabriel94

    Cheap,great quality,easy to apply to arduino builds,small,usefull in small compartments and overall a great piece of tech for DIY involving sound
    This sound sensor I had for intentions of connecting to my laserballproject to match incoming music to the pattern in which the lasers would blink it worked perfectly.
    Great piece of tech for those in need of a sound sensor for their DIY and worked very favourably for my project.
