As most profesional DSO are to expensive for an amature hobbiest I set out to make my own. The mission is to make a DSO that can rivle profesional ones like the Rigol DS1042C and others but on a budget of only €250 or €100 per channel.

The original intented featueres are:

* 105Msps
* 4Kb of fifo per channel
* 4.3" lcd (psp lcd screen)
* OSD + rotary encoders + switches to access basic functions
* 2 channels
* 8 bits resolution per channel
* triggers (single shot trigger, trigger en auto)
* time delays (0%-100%, 25%-75%, 50%-50%)
* FFT (through USB and special application on the PC)
* USB interface
* peak detection
* min-max-avg
* 8 channel logic analyzer (60 MHz, 4Kb of fifo)

The final features are:

* 80Msps
* 4Mbit of fifo per channel
* 8 channel logic analyser (60 MHz, 1Mbit of fifo)
