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.

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.
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.

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.
