This is a full-featured dual-channel oscilloscope based on the Picaxe 28X1 (or optionally the 28X2).
The Picaxe controls the sample logic (made from just four standard 74HC series logic chips), sets the input amplifier gain and offset, reads back the sampled data and transmits it to a PC for display and further processing. That way the processing speed is not a limiting factior at all.
This scope is in practical use by a couple hundred hobbyists.
