Default Low-Cost USB Hobby Oscilloscope

Recently the guys over at the Make Magazine website pointed to a low-cost oscilloscope. The address is www.pdamusician.com/lcscope.

Has anyone else looked into building this? I ordered one of his PC boards, and my parts are arriving over the next few days. I'm hoping to put it together this weekend.

One thing that has always left me feeling a bit handicapped in DIY Audio is not having an oscilloscope, and this looks better than the retail USB scopes.

For less money you'd probably get a decent second hand analogue scope. Why not try that? Or do you want it to be USB?

the 150 khz bandwidth is kinda low even for audio, RF can still be a problem in audio designs.

"Visual Analyser" is a free download and turns a decent soundcard into enough of a scope/signal generator to get you started.

Thanks for the replies!

Limhes, my concerns/benefits were:

1) The storage of waveforms
2) The size of the older analog scopes
3) The cost of purchase are quickly offset by the shipping costs of one of the old "lugables"
4) The pride of ownership, akin to the building of one's own audio components
5) Being open-source, I can tweek it if I ever get the courage to

cbdb: I agree, but this is a constraint I am willing to live with until (if?) I can justify the added cost of additional bandwidth

Yer Sexyness,

why not look for a smaller foreign scope ?
I lifted an Hitachi analog/digital storage scope from the web for $60, even had a fairly recent calibration sticker.
Found both the RS232 software, to hook the scope up to a PC, and a +10Mb complete service manual for the DSO on the internet within two weeks time.

Suck it up and buy a good scope. They hold their value.

Hi Scott, thanks for the link!

From all the PC-based software I know, this seems to be the most promising!

Have fun, Hannes
