This sounds awesome, Hippy! Do you have any pics or video? That project deserves its own thread.Just for fun with the talk of oscilloscopes in the air I thought I'd see how well an AXE133Y 16x2 OLED board worked as an oscilloscope. It's not brilliant as it only has a resolution of 7 steps vertical and 80 horizontal with gaps but, with wire on C.0 and held to pick-up mains hum, it seems to capture 5.5 cycles of mains which gives a refresh rate of around 110 ms.
This code runs only on the AXE133Y OLED board; an LCD doesn't have the graphics mode the OLED does. It's thrown together and not optimised at all. I'll see how fast I can make an optimised version work later.
This $16 kit also has its place: http://www.ebay.com/itm/DIY-Digital-Oscilloscope-Kit-Electronic-Learning-Kit-DSO138-2-4inch-1Msps-HPj-/111953382352
