Stupid Oscilloscope Tricks W/Arduino

Post by modeller »

A long time ago I made an HP spectrum analyzer display a TV picture. Couldn't hear the sound but it was a fairly decent black and white picture (well green and white). We also used to make oscilloscopes display patterns. I thought I'd try it with the Arduino.

Here's three I got going using the Arduino - square, diamond, and circle :D I only used passive components and programming.

Completely useless but fun.

Thanks.

I got that scope back in 1986, and I paid $461 for it. A Rigol DS1052 costs about $330. However, this scope is pure analog - no "funny business" going on inside that baby! But ... I'll probably buckle and get a new digital scope, I mean the screen colors are so pretty.

Here's a hexagon -

OK one more and I'm done. Used another digital output to feed into the blanking input to create dashes on the circle. Again sorry for the bad pic.

Ah well, on to bigger and better Arduino projects.

Hmmm ... I wonder if I could get brownie points if I made the scope display the Adafruit logo? 8)
