Simple oscilloscope

This is a very simple osciloscope made with some dot matrix led display. It can't measure the frequency or the amplitude of the input signal but it can show the shape of input signal. It has one input channel. The signals in the video are a sinusoidal wave, a square wave and a triangular wave, with variations of duty-cycle.

ma è un unica matrice led?? Se si dove l'hai trovata?

[Alu10000]

No, sono 9 matrici 5x7 affiancate.

WOW!! Great work......

Could you please sharing the circuit diagram and part list........Thanks

[Magneticitist]

that is absolutely brilliant..

[calypsoCRO]

OMFG!!! you're damn crazy!!! you got thousands of wires!!! great! So, are you working in CERN or NASA?? XD

thanks

[Alu10000]

No.

[3v45b5]

it really is an awesome piece of work. I would love to have one for my synthesizer, would you mind sharing the partslist/construction manual? thanks a lot!

[samulokoo]

yeah dude very nice

[6364gg2]

Could you please document the construction? Or at least make part list?

[picbuck]

Freakin' awesome. Whoda thought it could be done.

Respect!  That's a great piece of work! What ADC are you using?
