Cool project, but the link is wrong – It goes to his monitor tester (which is equally useful)…

Ahhh there we go.

Thanks lurker

i think your link is wrong … or maybe you imply that you can make a scope with that XD

A very nicely built project, but the 10K input impedance seems rather low to me..!

Neat but since I don’t know when to use an oscilloscope I guess it isn’t really for me.

What kind of voltages would something like this be able to handle? I have seen many Atmega, PC, and those other oscilloscopes but I somehow don’t think they were designed to handle very much power. I can see using it as a way to measure voltages like the pulses from a 555 so… I assume it would need to be able to handle some power.

There are many projects like this out on the ‘net. The problem is the painfully limited bandwidth, and the horribly low input impedance.

Yes, this is cheaper than getting a RIGOL and hacking it, but the RIGOL is infinitely better than this oscilloscope in every way. This is more of something that you show off to your fellow students to make them ooh and aah. It does look cool, but I can’t think of any practical use in an EE lab.

I suppose this would be good for audio-related uses, though :D

What I’d really like to see is a combination of the two projects: an oscilloscope driving a standard external monitor. Still quite neat though.

Jake, you are right, it is too limiting. Still, the most critical part of it, the ADC is rather cheap and easily available.
If somebody is skilled enough, the analog part may be modified for higher performance.I’d change the display for a Siemens S65 phone one(cheap, available, easy to connect).
The best way to make one using a normal monitor would be using an FPGA, but that complicates things.As for the Rigol scope, i am too a proud owner of the easily hackable one. Highly recommend it.
