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.
Life does get rather busy sometimes. For us it was having a baby and moving house in the same week. Subsequently I’ve been rather preoccupied.
But that was nearly 6 months ago and things are getting a little more sorted out now, plus it was my birthday recently so I thought it was about time to get back in to electronics and also to add some new posts to this blog.
