[sdiy] Recording voltage changes/fluctuations for post-analysis

[Justin Owen]

Hello,

If I wanted to set up the facility to record changes in voltage at a particular point in a circuit over a period of time - let's say up to 30 minutes - and then have it in a form that could be analysed - let's say in Excel (ideally) and/or some form of graphic (as a bonus)...

...what sort of kit would I be looking at?

Voltage changes probably no more than +/- 1V and for home/small business use rather than MilSpec/CERN/NASA - basically I'm looking for a step above sitting staring at a multimeter :)

Thanks!
