I just received my new Digital Storage Oscilloscope by JYE tech from the Seeed Studio Depot. While it is certainly not as powerful as a full fledged oscilloscope, its compact size and affordable price ($49) make it a handy tool for any electronics maker. For someone just learning about electronics this scope will help them understand the consequences of changing various component values, signal levels or circuit designs of pulse or wave-shaping circuits (oscillating circuits that produce waveforms) or let them take a closer look at serial communications. I’m looking forward to watching the waveforms as I build some simple FM synthesis with basic oscillating circuits.

Scope And Schmitt Trigger Oscillator
A nice bonus of the scope is that it is based on an AVR microcontroller and the creator provides documentation to help get you started hacking the device. Learn to program the scope here, and how to add an external trigger here. If you are interested you can read the operating instructions here.
