This is my first oscilloscope. Initially I tried to power it from my 9V power supply but it didn't work. I thought the oscilloscope was faulty. But when I powered it via 6 AA batteries, I realized that it works as expected, the problem was that my power supply had inverse polarity! I am happy that I didn't burn the device with it, probably it has a protection. I like it because it is cheap, intuitive and open source.
