just plugged in my little chinese 5v wall wart that come with my cnc kit form keling/automationtechnology

i was not going to use it because it felt to cheap, and i was sure it had no regulator. just for kicks i wanted to see how close to 5v it is. plugged her in and measure the dc voltage with my fluke and got 26v dc! after about 20 seconds plugged in something inside popped and let out some majic smoke!


good thing i didnt try powering my smothstepper or BOB with it! keling should stop selling those. 5V Breakout Board Power Supply | Automation Technology Inc
