I made my own oscilloscope and modified it.

I wanted to have an oscilloscope while repairing the audio, so I made it myself.
I needed a 9V adaptor, but the power cable was in the way, so I equipped it with a lithium-ion battery and made it wireless. I think it's a perfect product for a practical electronic craftsman.
I have posted information about the tools and equipment on Twitter.
