A quick look at a x0xb0x that is being made by a work colleague (SuperNick). Since this video was made he has successfully tested board using an audio card oscilloscope to show the sawtooth and square waves.
If we are lucky he’ll make me up some tunes to go with some of these videos. I sometimes think I am going crazy due to the same six songs, over and over and over and over. Stay tuned! 😄
