Designing a homemade PC oscilloscope circuit

[sinatra]

Hello all.
Does anybody arround know about any simple, easy to build osciloscope circuit that can be interfaced to a pc (serial or parallel ports)? A homemade sampling head (not real time) would already be usefull....
My old osciloscope just stoped working and I would like to build something reasonable that could replyce it
Thanks to all.
S.

Hello!

Above links are dead ?!? I searched with Google and found

https://www.bitscope.com/

witch is alive. The best of luck with building this complicate device (complicate atleast for me) :-?

Hello

I don`t know if I help you with this, but, if you have a sound card on your PC you should use the input of the sound card. You`ll have at least about 40kHz sampling rate osciloscope (depending on the type of the sond card). For display the input signal, look on the net there are plenty of these programs.

Check out epe (everyday practical electronics) website, they have produced such scopes in their recent issues.

Try this one http://www.dsoworld.co.uk/. It is extremely cheap, powerfull and fast. The only thing it lacks is Input signal level selector but I guess that could easily be made with some resistor networks.

Hi Rostfrei and others

the links in the previous posts seem to work. You have to edit the link first, you cannot press the posted link and get to the site directly.
Check the bitscope site again because they anounce some new hw/sw projects. The ongoing development of the BS was the reason why choose it instead of the cheapre ones on other HP.

Hello x 8)

I know I have to edit link first (copy & pase in new window ), but I still get 500 error.

Thanx anyway !

I know very cheap and simple device. There could only some resistors and soft on PC.

i would also suggest using a soundcard (they have verry good ADC´s)
if you need higher sampling rates it hill be expensive !!

I'm using this osiloscope , try this link.It cost me only 2$.There is two IC and I get it as a sample from MAXIM company.
