A friend asked me about the oscilloscope I was using in my last post, you can see it in the very poor quality video at the end of the post. So I thought I’d make a quick post to explain. It’s called the DSO Nano, it’s sold by Seeedstudio and the short of it is that it’s a fantastic tool for a great price. It is limited in bandwidth, and has only one channel but I love it all the same. It has around 1MHz of analog bandwidth which is admittedly quite low – giving a useable working limit to signals of around 100KHz – but that is more than enough for audio and fine for just about everything I’ve been doing such as debugging my PWM output from my LED fader.
