Check out this DIY Oscilloscope using Atmel Atmega32.

I wanted to see if I could make a useful scope using just a microcontroller and a television. The result works, but is a bit slow with a maximum sampling rate of 15,750 Hz. This is fast enough for most electrophysiology, but not for audio. The sampling rate is determined by the maximum rate of the internal A/D converter.

  1. [...] Here’s a cool DIY oscilloscope using a PIC12F675 kinda similar to the Atmega Atmel Oscilloscope. This is a simple PC voltage oscilloscope using only a PIC12F675, a 20MHz oscillator, and a RS232 level shifter. The PIC takes a sample on GP2, immediately sends it to the PC at 115,200 baud using an software asynchronous serial routine, and repeats. It sends a 8-bit value that is read by the Visual Basic software and displayed on the screen (see examples below). The Visual Basic software deduces the time period between submissions and adjusts the display accordingly. atmega, atmel, build, Circuits, Cool, diy, diy oscilloscope, DoItYourself!, educational, engineering, Hack, howto, howto oscilloscope, Industrial, make, microchip, Microcontroller, oscilloscope, PIC, science, technology, zedomax pic12f675 [...]
