FPGA Digital Oscilloscope
The guys from fpga4fun have this interesting recipe for a simple digital oscilloscope which is made with the following parts:
- 1 x Pluto FPGA board, with TXDI and cable (item#1121, $39.95)
- 1 x Flash acquisition board (item#1200, $29.95)
- 1 x BNC (item#1250, $4.95)
- 1 x Nylon standoffs (item#1270, $0.95)
- 1 x Male/female connectors 2×8 (item#1275, $2.95)
That’s about $78.75 so you can also call it a cheap oscilloscope because all commercial oscilloscopes are priced higher than $70.

I’ve been looking at this “project” for quite some time, and am always on the edge… But I wonder what it would take to interface this with an LCD, like shown at http://www.youritronics.com/graphic-lcd-pannel-interfaced-with-fpga/? The skillset is way beyond me, so I wouldn’t even know where/how to attempt this, but I wonder why they (fpga4fun) hasn’t made that step yet?

it sound like allot of codding hours to do that, so maybe that’s the reason they haven’t done it yet. You have to consider that all the graphics are generated by the computer and you’d have to move this function on to a mcu.
